Hey, Berry!!! How about some more shots of that eye candy hanging off the red "B"? Packer

Don't have time to get my BMT AND my 1943 Pumper truck running. One of them has to go! Any one interested in a Dodge WF (1 1/2 ton) fire truck? New tires, flaps, and tubes Rebuilt carb and tune-up Runs and stops great Runs like heaven, but looks like Hell - - - new paint would do wonders!!! Asking $5000.00 Can deliver most any where. Packer

The tire is 'X' number of inches around and thats how far it will go in one revolution. That does not change! There may be some change from speed or heat but the change is not so much that it would cause any drastic changes in the formula. Radius "AT THE RIM" may change. Circumference of the tire stays the same. It will always be 110 in. (or whatever) flat or overinflated. Packer

Thanks for the kind words, Fred - - - or are you saying I'm a dummy?LOL Packer

I see a "Train" wreck in the works!!! A syncro might be great for the driver, but sure is gonna be hell on the truck!!! Imput shafts, clutch, engine, axles, drive lines - - - the list goes on!!! You cobble a gear and something is going to come apart, and right NOW!!! Better stick with what you got or get an automatic! Packer

The adjustment is something like "Down to touch and back off 5/8 (or 3/4) turn". Be sure the valve lash is set first, then adjust the Jakes. Incorrect valve lash will mean incorrect Jake adjustment. Packer

On a Cummins engine, with only one head turned on, and a new rebuild on the engine brake, the brake will kill an engine at idle. With all working and even a little oil leaking by, the brake will kill an engine at idle. With the engine idling and you here a little putt-putt-putt sound, that's an indication the brake is in need off an hour or two of TLC. The only dynatards I ever drove were while test driving at the Mack shop in S.L.C. UT. At that time, the only other engine brakes were Cummins and that was just after I had rebuilt them. The Dynatard may have been weak and I know the Jakes were strong so I may not have had the whole story. When driving with and for my Dad, we would get 350,000 miles from a set of brake linings. when drivers were add, the brake life dropped to 150,000 miles. When lease O/O were added, trailer lining went to 50,000 miles. The old Jake instructions said to "Use the same gear going down hill as going up"! Something to think about! Packer

Just got a rebuild kit for my 2 valve 237 Jake brake. The cost was $95.00 plus shipping. Got it from Tec Brake. If the 'O' rings are hard, cracked, etc. or pistons galled, the brake won't work to it's capacity. On Cummins that's about equal to the rated horsepower. Macks do not have the injector rocker arm to get top-dead-center on the exaust stroke quite as well as the Cummins engines but is still way ahead of a dynatard. Packer

Hey Thad! "If it ain't broke, fix it 'till it is"!!! The first truck I drove had 205 horsepower. It made for a longer day but also a cheaper day! Did you put a 'chip' in your pick-up? Neither did I! Back in 'The good ol' days' (about three days after dirt) the more horse power, the lower the reliabilty. You got a good one now, and you own it. Pass them at the fuel pump and get your pay-backs then! Packer

Hit me with a price we can both live with! I'm easy! Packer

Time to toss in my nickles worth! 25 years ago I new I would never need a CDL again and did not renew. Now, according to the Wyoming D.O.T., If I drive 'ANY' vehicale over 26,001 GVW, I 'WILL' have a class A CDL. This is driving my own truck, pulling my own trailer, with my own load (Old Trucks, etc. that I own)! 'AND' the GVW plate is for over 26.001lbs. This has nothing to do with the scale weight, only the GVW. It gets better! If I plate the truck for say 40,000lbs, don't be crossing the scales at 40,100 lbs 'cause the fine is way up there! Ain't the the red tape of goverment great!?! Packer

I've got a 401 that I drove 47 miles home. New plugs, new wires, rebuilt carb. FOR SALE (cheap) Packer And I may even deliver! Packer

Could you have rust in the cylinder/pistons? Takes a lot of juice to turn a rusted motor! The fact that it turns every time says that the batteries are trying, but "if" there is rust,gunk, bee hives, old stiff oil. a rag,- - - whatever. That could be taking the magic smoke and using it to turn over the engine, but jams every thing tight. (rust, gunk,etc.) Might be rusted liners,rings,pistons,crankshaft, from sitting so long without oil in the bores and on the bearings. Here's a thought - - - Is the truck in netural? I'm not trying to insult you! But stranger things have happened! (I ain't laffin) Packer

How long since the 'B' has been started? Will the batteries turn the engine over time after time but only 1-2 revs each time? It's normal for the cables to jump. It's caused by the high amp draw through the cables, making a magnetic field. Packer

Looks just like the one on my gasser. That's a partial or slipstream or luberfiner or or - - -??? The filter only filters a small percentage of the oil that the pump puts out. If you're in a hurry, pull the filter, make sure the inside is clean, fill the filter can with oil (no filter) and crank! The system is built to run on clean oil with a small amount of filtering, as opposed the full flow filters that filter all the oil, all the time. If you look at the bottom of the picture, that little line comming out is the 'Oil Filter Return Line'. That is all the oil that the filter is cleaning. The input is a hole in the block that is tapping the oil galley, letting some oil into the filter can. Hope that helps. Packer

Is this a 'Full Flow' filter? Or a slipstream/luberfiner? My 402 gasser had a little by-pass type filter that was plumbed with a 1/4 or 3/8 hole and only picked up a very small percent of the oil. I dumped the filter out, put the top back on, filled the crankcase, and drove the truck 47 miles home. A full flow filter has other problems involved but I think most have a by-pass in the filter to make sure that if the filter plugs off, oil will still go through the engine - - - But at a lower pressure reading on the Gage. Remote filter? Start it! Full flow? better wait! Packer

The S/P switch should be a gone item if you switched to 12 volt. If you left the S/P switch in and hooked everything back as a 24 volt system, - - - you might melt a battery post off and have a clicking sound under the passenger seat! (I ain't laffin) Electrical systems are a killer; they are not forgiving, they work like you tell them but maybe not as you want, and if you goof up too badly, all the magic smoke escapes! Good luck and hang in there! Before you're through, you WILL know the wireing system, even if no one else does. Packer

Good stuff Joe! I printed the whole dern thing for later!! Thanks Packer

My goodness Thad, that's a lot of info in such a short email!!! LOL "S" cams roll and are operated, by air, at 0 degrees to the brake linning. Wedge brakes are 90 degrees to the linning, and "Wedge" the brake shoes out. Saw an old Mack with what may have been an up-grade kit for Maxi/Spring brakes (they're the same thing). Had the spring cans bolted to the frame between cab and drive axle. There was a cable comming out of the can and running down and back to the slack adjusters. When the switch was operated, the spring would pull the cable which pulled the slack adjuster, which pulled the brakes on!! Packer

A quick check says: 47,459 B61 8,780 B67 Missed a B67 buy a week once - - - Glad I did!! 2,144 B421 Packer

I worked at Mack's Salt lake City, UT dealership in the late '70's. One thing that I noticed is that on the air cooled engine, if you lost one turbo, the other shelled out also. Never had much good to say about the two turbo system but - - - I have no idea what may have caused the turbochargers to come apart. Was it poor oil? Too many miles? Bad air cleaner? Bad turbo? I may never know the answer to the question. At the time I was just a youngster and was the Cummins mechanic in the shop. Did some work on Mack engines; rebuilt several, but didn't take the time to find out why the air cooled seemed to have that problem. Packer

I think if you check, anytime you haul for hire, you need a CDL. Out here in the Wild West, you can drive 'most anything, A) If you own it and if its under 28,000 GVW. I hauled a cabin kit for my son. No charge, but he bought fuel. That's OK. If he pays me $1.00 mile, I'm now 'hauling for hire' and crossing state lines (3) - - - Well, that's another ball of wax! Packer

Just happen to have a dynatard. Took it off my 237. Looks good and clean! Make me on offer!?! Packer
