The only compressors I'm aware of that had timing issues, were the earlier Cummins compressors, manufactured by Cummins. Since the couplings did not have a master spline they would fit and work any way you could stick them on. If not timed properly they would rattle even more than normal, which was really bad. If I had a failure on one of my own trucks I always tried to round up a Bendix to replace it. Mostly a used unit, to get the necessary parts to change it over. Today, it is easy to get an argument started over where they needed to be timed in the first place. I never had to tie a rope around one on a Cummins, but I have used the rope trick on starters several times. If you could teach the puppy to hold the rope or start the bolts, it would be a really good trick.

I'm glad you straightened that out, reception for anything might not be to good from under the house. It would be even more miserable if she also had custody of the dog.

PAI's complete "selectair" valve is not out of line on price as I think mine was about $60.00. I did not use it as I actually "boiled" mine in hot water, (yes, on the stove) to clean the accumulated garbage/buildup from it. It works as new now. Mine had probably never had the air filter changed in it's lifetime, (exaggeration).

My shift cylinder kept leaking internally around the hi/low piston internal to the transmission. I found it by removing only one top cover bolt and it was like a tornado through a keyhole from the air escaping. I then removed the shift cover, tore it completely down again, boiled it, (same way on the stove), then honed the cylinder with a small cylinder hone and boiled it again. It was then put back together without any problems, (so far).

I guess now you can see why "Momma" gets so angry with me. At least I changed the water before boiling the hot dogs in the same pan.

It works very well on lawn mower carb's also, Just a suggestion, but if you boil the hot dogs first you won't have to change the water. And as an added benefit, you can also clean and lubricate the parts at the same time. If you save the water to wash your hands afterward they will smell like hot dogs and she won't complain about you coming in the house smelling like grease or mineral spirits. Leave the pan outside, and the dog will be glad to clean it up. Works for me.

A buddy of mine has a '86 International cabover that has all of the sudden started overheating on the least little hill. He was haulin full time with the truck but bought a Western Star and only uses the cabover to pull a reefer trailer around a 100 mile round trip on saturday. The truck is a low mileage truck around 400,000, and the fuel is set on the factory settin. Just the least little incline it'll heat up then shut it's self down. Bobtailing it does fine, but even pullin his savannah log trailer around EMPTY it'll try to heat up. He replaced the water pump with no luck and is wondering what to look for next. Any and all help would be appreciated. Thanks guys

Joe, on models with Horton, or similar fan clutches, the same Kysor shut down also controls the fan clutch. Whether viscous or air operated the fan clutch would be the first suspect. See what it has. If it is air operated look for a manual switch. If no manual switch, jump the solonoid with a test lead to make the fan operate, and test drive it. A quick test for a suspect Cummins water pump is to attempt to lay your hand on both top and bottom radiator tanks, when the engine is showing hot. If the bottom is a lot hotter, it is not circulating. Cummins uses a lot of phenolic impellers in replacement pumps. They are prone to turn loose and spin on the shaft. Due to cavitation, over time they will sometimes lose the vanes. They always end up in the oil cooler. If you pull one of these pumps, and find part of the vanes missing, do not pass go or collect 200 dollars, but pull the oil cooler and clean it out before using the truck. If you can't find your problem, call me. James

Can I ask why anyone would use motoroil instead of lighter transmission fluid. I realize the weight is heavier with motoroil but ATF has always been a magical fluid for any temperature extreme. Looks like the motoroil would have to be changed more frequent and have more problems with heat exchange or cleanliness.

Thanks

mike

The rationale for using engine oil is that on engine mounted pumps, a defective pump seal could and sometimes would, deliver steering oil into the engine sump.

You could say, Well, it is just what you get used to. But enjoying what you do, and absolutely loving every minute of it, smooths all of the ruts out. My oldest grand daughter is 21 now, but when she was about 1 1/2 I had the first opertunity to let her have a ride in my rig. In the bright sunlight, as we pulled out into a long clear stretch of highway, she leaned forward, slapped the dash, and gave a tremendous rebel yell. My daughter, who was holding her, said she's really getting in to this. Without having to think about it, I said, honey I feel the same way every time I start out in this thing. On another note, my dad was career Air Force. Having spent most of a 3 year tour of duty in Japan with him, we were just back in the states. It was another bright sunny day, and as we left Travis Air Force Base California, dad pulled onto the freeway and started down your side of the road. He couldn't understand why I was yelling, or why all those other S.O.B.'s were on the wrong side of the road. LOL

123 oil water and egt. 456 fuel pressure boost and trans temp, 789 air pressure volts and fuel level. If you are trying to have a factory set up I just don't know Paul Van Scott has a 66 with all the guages in the speedo cluster. My 73 has all of them with exception of the air pressure mounted in the center of the all steel flat dash. What ever you come up with would suit me fine. I like the idea of rebuilding something bigger, better, faster, and neater. If it stands out, and shines like a new penny, so much the better. Quality craftsmanship never gets old or never goes out of style. Fix it the way you like it, that's what hot rod's are about. What could be better than a hot rod Mack with a 60 in, air ride cab/bunk, a hanging brake pedal, and a custom guage package.

Since you are starting with a clean sheet of paper so to speak. It all boils down to what kind of an operator you are. It wouldn't matter to some, as long as the arrangement didn't compromise the CD changer or the CB radio. I would mount them the same way that you do in your race car. With an uninterrupted clear line of sight to the most important. OIL pressure, water temp, and EGT, and I would probably clock them to read the desired results at 12 O'Clock. I would mount the rest of them the same and conveniently as possible. Someone else getting in your truck might think you were drunk when you installed them. But, you could read them all at a glance, without really looking at them. I have never had a fuel guage that lasted much longer than the warranty, so any place you can find to lay your stick would work. LOL

Guys ya can pretty much go with the simple stuff to a point on these engines but then you get thrown a curve ball EGR.Adds a new dimension to the fuel air theroy.Heat, boost preasure exhast preasure inlet air temp humity exhast leaks,yada yada,Not a simple engine anymore, sensors have targets to meet if they don't meet the targets they don't run right. there anit nothing simple about this problem, to many added features to monitor.Its not just as simple as air vs fuel these days.

I could not agree with you more, due to the complexity of the controls an internal combustion engine is no longer simple. Gas or diesel. That makes your job in the shop a lot harder. The basic engine however remains the same. But, you now have a lot longer list of possibility's that affect the same results. Separating the cause's from the results is a greater problem. Being able to separate them separates a good tech like yourself from a not so good tech. You have got a good attitude, you can handle it. I always figured that if someone designed something and someone else assembled it, then I could fix it. I'm not so sure now. I liked it a whole lot better when I could overhaul one on the side of the road.

Hello, there are not many petes down here, there is a few kenworth 60 inch bunks around and there price is around 4500.00 bucks. will get one sooner or later.

Grant

I have began to see signs that some of the California guys are selling off some really nice older Pete's. It won't be long until they can't use them anyway. California is considering raising the weight limits for agriculture to 96,000 lbs. The thinking is that they can reduce emissions by using fewer trucks. Wonder how long it will take to figure out that you can"t stop the suckers. You could get around like that fine, so could I. but the simple fact is that everybody can't. In today's business climate it is hard for me to understand why anyone would want a truck. Shipping from the states would probably preclude buying a bunk here. I have no doubt that you could buy a whole dang truck for $4500. I have a dandy 40 in. sit in I would give you if you lived a little closer. After looking your project over, I'll have to start looking for another RS700 to put it on. I can tell you now though, that I am not putting the steering wheel on the same side that you did.

If you haven't already purchased a bunk, and can"t find a suitable Mack offering, you might take a look at a 359 Pete flat top. I like the notion of having a door on each side.

Two essential elements are required to build a fire. Fuel and oxygen. Normally, until a cold diesel engine reaches operating temp, it will emit a blueish smoke. Then the closer it It gets to 200 degrees, the smoke becomes neutral. Depending on the time of manufacture, you will see either more , or less black smoke, as you add fuel to a warm engine. Black smoke is a result, not a cause. Black smoke is caused by too much fuel, or not enough oxygen. A restricted air supply is worse than too much fuel. In extreme situations the fuel will put the fire out. At highway speed if you see white smoke under acceleration, the engine is adding oil to the fuel, or an excessive amount of fuel is cooling the combustion process. Again in an extreme situation you might be seeing raw unburned fuel. A high EGT is also a result not a cause. Again, it takes fuel and oxygen to build a fire. To build a 1200 degree fire you need a lot of fuel and a lot of oxygen, or too much oxygen, thereby leaning the combustion process. The new generation electronic diesel engines are more effecient, to a point, but a lot harder to diagnose. Engine basics are still the same regardless of what controls when and where. It still is just a big heat pump. It takes BTU's to make horsepower.

I would "lie in wait" for the opportune time to bring it up.

You would be amazed at the amount of things I have said and done through the years that "Momma" brings up to further her own agenda at my expense. Sorta like laying in bed on a Saturday, after a hard work week, while she was in college. Somehow during her analysis of problematic world affairs using compassion and reasoning, I blurted out the comment; "Well if your gonna lay here and psycologize my ass, I'm gonna get something to eat. Or the time I knocked over the elderly lady sitting in her wheelchair at the grocery store, or the cheese cake comment, or tripping the fire alarm at the movie theater, or chain bindering a guys car doors shut in a public parking lot............

Rob

It would probably be a lot easier on you to just hire a couple of big boys to stop by every few weeks and beat you up.

I think I'll cry some too.

Your comments about RPM's and the chevy engine sounds a little odd. They have an entirely different reputation here. On the other hand, us ford guys here have had to suck hind tit for years. The 335 series, or Cleveland engines were in production for a short while, and you guys can still get good stuff for them. The high bearing speeds and crummy cylinder head castings of the Windsor engines are, or were a limiting factor. I am talking about normally aspirated engines. You can stuff, and puff a Honda Civic and out run anything we had to work with. I saw your coupe in your gallery, Nice. Made me think of Mad Max for some reason.

getting there, now my biggest problem is working out how I am going to keep the noise of that engine out of the cab, I wanna be able to here a mouse fart in there, any ideas?

Holden is part of General Motors/Cev, but hey if you want to rev it, dont chev it! Fords are the go, specially blown ones! my ford coupe is in my album. how ever in saying that GMs um dont have power they back there product much better than those turkeys at ford, I will never buy a new ford again in this country.

when I get to the USA will consider it?? hey whats the laws over there for driving say a mack with 3 x 45 footers hanging off the back? how grumpy will the cops get? ) would look good pulling into a truck show for a display.

regards Grant

You could hook up on site at a show no problem. If you were to show up pulling such a rig with out 14 escort cars and no permits, the police would probably $hit an entire very large cow. If you were to show up loaded as you guys are subject to, you could expect to spend 20 years in prison with out time off for good behavior.

Hi Guys.

Just found this and thought our Stateside mates might like it. Enjoy. Rod.

Good songs, and fine looking trucks

yep it sure did! firewall ready for paint now.

Looking pretty darn good. Now, is Holden the Australian word for Chevrolet. Where and what kind of racing do you do.

Hi, bring it on but um how long are your triples over there? ours are 173feet long as we haul 3x 45 foot trailers and 264000 lbs, my album has a few pics in it, the road houses are 310miles apart with nothing in between and depending where you go there is is 600 miles between 24hour road houses all the others are shut.

temp is around 120" with the occaisonal flash road fluds of 3 to 5 feet high!

Triples here would consist of 23 ft. pups. We have very strict laws about public nudity here, Three 45's would scare the pants off just about everyone. We do have flash flooding some times in the US. However, up till now I would not have considered carrying a stick to ward off reptiles and other unwanted guests. I can just see one of your 40 ft. snakes trying to get on top of the trailer with me.

My 73 RS797LST had some of each. That is not surprising, considering it's age. My observation is that the plastic seems to hold up better. It weathers better and apparently is impervious to oil, inside and outside. It is less expensive and easier to work with, but it wont stand up to heat as well. As far as to what is original, only a build sheet would tell.

The cherry picker idea is a good one. When installing the Camel Back trunnion in my RS700, I was able to borrow a heavy duty Milwaukee unit from a friend. 45 to 50 lbs. sounds about right. To begin with my impression was, hey this thing is as neat as sliced bread, what a wonderful invention. I soon found that even with a rotating base you had to position the drill close to where where you wanted to drill. Then with both hands and a knee holding the drill in position, I couldn't turn loose to turn on the magnet. No problem I just turned on the magnet first. Wham, against the frame rail, close but about an inch off, dang. Release the magnet, turn it back on, wham. Man I love this drill, but it is getting to be an arm full. I haven't reamed one locating hole and this sob is whipping my a$$. It's a good thing I'm a tough and determined old codger. I know exactly how Herb's arm felt. It takes a lot of oil to cool the tool bit, and you have to take the time to keep the mess cleaned up. Otherwise the magnet will move around on an oil slick frame. My project was compounded by the fact that the mounting holes in the used trunnion were already over sized. Once the trunnion was in place, and secure. I had to make a pilot bushing to fit the holes in the trunnion, and drill a pilot hole from inside the frame with a hand drill. Then use a piloted drill bit to inlarge the hole, then finish ream frame and trunnion to fit the trunnion bolts, which I had to make. It took the best part of two days to get it bolted in, after which I loaded up that crummy drill and took it home before I saw something else that needed drilling.

You have done it now for sure, Rob is a road kill chef. You can expect at any time now for him to start pestering either you or Knobby to sponsor him for citizenship. Since I am also licensed for triples I might come as well. Since I didn't see any buildings in your photo it might be a good place to put up a road side cafe. I can almost see it now " Rob's Road Kill Cafe" We could keep his cooler well stocked, and with acres of parking it should be a quick success. I would be interested to see more trucking pictures. Other dog is an avid photographer, and often posts pictures of his weekly travels. Click on Blogs at the top right of the page then other dog's blog to check them out. Cheers

HELLO EVERYONE. a personal freind is in the process of buying a 1958 B-61 , with a 673 engine and quadraplex. Truck comes with another 673 engine quadraplex and two axles. Looks as if i will be having the oportunity to start a restoration. I have already recieved lots of info from this site. In its life the truck was a house moving truck. thanks in advance for all your help.

Welcome to the site, all you have to do to make friends here, is show yourself to be friendly. I hope you have a good time with your project, and a fun time on the forum.

Tom, and myself, are both over the road drivers, all over the road that is. So we should fit in quite well. Either side of the road works for me. Some of the roads here are so crooked and narrow that we are able to drive on both sides at the same time. I should mention though that we don"t like spiders and snakes, or croc's for that matter. Is your govt offering a stimulus of any kind. Mine came today, a half lb. of water mellon seed, two bags of corn meal, ten baby chickens, and a case of Budwieser. I would have preferred Fosters if given a choice. Keep the pictures coming. I liked the hanging foot valve, good idea.

The firewall is going to look good. It looks like you are making holes in something else though. Be careful or you might have some holes left over. Now if they were donut holes, Rob and I could take a couple of dozen off your hands. When you set on the wrong side of the truck to drive, do you drive on the wrong side of the road? I am getting more confused than usual, it has been cold as a pickle and raining, snowing here, and dry as a powder house, and hotter than a pepper sprout where you live. Something is a little off, but not a matter for great concern. There is a rumor however that some of you fellows down under like fast Fords and cold soda pop. If that is true, and with your enthusisam for old Macks, then down under might not be such a bad place. Aside from your govt's hinky view of gun ownership that is. Write soon, James
