I have hauled semis all over the country and have been stoped by a few state police with a 32 foot dual tandem trailer and a single rear wheel ford f350 superduty. The cops were more worried about if I was hauling commercially or for my self, when I explained that it was a retired truck they were just fine and were very pleasant. I have never had a problem as far as loading, unloading and hauling. I did loose a wheel bearing in Pennsy. one time but I dont believe that was the trailers fault (chinese bearing). Is your dove tail in the up position on that trailer or does it not have one? I have had v8 superliners on my truck and trailer so a b should be a cake walk. Morgan

Is the old reefer unit used as a stand alone power unit??? That would make one hell of a air conditioner!

could it be he got a bad batch of his famous road kill chill? Got to watch those "possums" this time of year, They have have a build up of toxins from the winter months.

Thanks for the help Pawel! I searched for a while and found the information on another web site. Got my gaskets today and hope to have it back together this weekend.

Morgan

can someone help me with the proper procedure for setting the over head on this engine, I need the clearances for the intake and exhaust and jake brake. I need the torque specs for the head bolts also, It is a ntc400 1983 engine. Thanks

Morgan

Bollweeviel, I think I have found the issue with the head bolts. All the bolts were on the outside of the rocker boxes. The ones that were broken were corroded. The rust would expand and put pressure on the bolt with the pitting of the bolt and heating and cooling. I talked to a friend of mine that is a Cummins mechanic at Indianapolis cummins branch, he said it is quite common in our part of the country but unheard of in other parts of the country. He also did his magic and got my cpl number and the correct number for the fuel pump and injectors. The pistons look very good, you can easily read the part numbers on the top and the sleeve part numbers. I am planning on dropping the pan and checking the bearings. I like your tip on the push tubes. Those injector tube sure do take a beating If your pump is turned up and the injectors don't flow enough fuel it can really add up to some serious pressure on the valve train. This engine has been left stock so I dodged and bullet there, I contacted the owners that ran the truck and pulled the engine. He said that the engine was majored no too long before the truck was rolled over and totaled. Did you look at all the pictures of the engine in my gallery? I posted a link to it in my last message. I thought It looked fairly clean, I think the guys I talked to were shooting straight when they talked to me. Thanks for your input!!!! If you know of anyone that has a cummins powered superliner thats junked I am looking for a front engine crossmember. THANKS

Morgan

OK, got some time tonight to tear into this engine, as I removed the heads I found 2 more head bolts broken, one was broken down below the deck so I would have never got it removed without removing the head, I think the old engine looks good and clean inside. I have some photos with captions in my gallery labeled 81 superliner.

Morgan

Ok I have the CORRECT block number for my engine 11139721, This engine and the other must be built almost at the same time with block numbers so close. I will change the head gaskets, and I might as well grind the valves and check the rods and mains. so much for a quick and cheap install. I will know what I have and hopefully I won't have to go back in to the engine for a while. Do I need to document my engine pull and work with pictures and up dates with it's own thread or do you guys seen all this stuff and is all "old hat"? Thanks

Morgan

Ok, where is a good place to get parts for these engines, Parts are high these days and funds are low. I hate to spend too much for a truck thats more or less not going to "earn its keep". I have seen the after market stuff is cheaper but I know the quality might not be there. Thanks for the information on the engine, but I also gave you the incorrect number(yes I am a dumb ass) I will get the correct number. I called cummins on the phone and also two autorized dealers and they really didn't want to give me any info other than it was a ntc400. no CPL or anything else, they said it couldn't be done.

Morgan

Thanks,

This is a motor that I will be installing into the truck, I haven't heard it run yet. The good news it is the front head so going back in for repair might not be as bad as say the rear head. This engine also has no cpl tag, I have the block number will that get me the information on the engine? 11136723 who do I talk to to get the info?

Morgan

Hi,

I have a 855 cummins for my superliner, While pressure washing and cleaning I found it to have a broken head bolt, I used a punch and spun out the rest of the bolt. Is this common? Would the headgasket have a chance of being ok?

Morgan

Would this truck been built with a v8 engine?

federal safety standards. I was told this by members of the PPPSI during a presentation they had during one of our truck club meetings. The man was very knowledgeable about fire trucks, Boyers are his speciality. I am no firetruck buff, but after his "show" I never have been able to find a truck made after the mid seventies that was open cab. Now that I have said this I am sure that someone will post a bunch of 80's models with open cabs....As for the riding on the tailboard that was a big NO,NO when I was on the volenteer fire dept. they said it was outlawed sometime before I started. That could be an Indiana thing though. This is the basis on witch I have my information.

in the early 70's safety regulations required that the cabs were closed. they also outlawed riding the tailboard at about that time also. Most rual fire departments had closed cabs and most urban had open cabs, not much need for a open cab truck in the country because most were pumpers.

I went on thursday afternoon, It was great. Got lots of 'goodies' to take home. I always enjoy the MATS show. I wish I could get in on thursday morning during the VIP times.

Morgan

The engine is referred to as a 350 cummins v8, I have seen a few pictures of these but, most are not turbocharged, they were made to pull doubles on the new york thru-way, backed with a quadraplex. all 10 were made for the same company Mcbride in new york state.

Morgan

One thing to take into concideration on the number of single axle b75 is, quite a few of them were equiped with a tag axle making them look like a tandem, I have noticed a lot them in old pictures that had tag axles installed for over the road work. I have a single axle b733, and remaints of a b79. the 733 is a cummins powered with a turbo and the b79 should have a v8 cummins engine, the v8 before the 555 and 903. I am not for sure the cid of the original engine but it is long gone. the first two years of production of the b7x's production the trucks have the smaller b61 style radiator grille also something to look for,

Morgan

I will be cutting back on truck shows as well. I want to go to Walcott this year with my truck, and that will blow the entire budget. No other far away shows for me this year.

Ok, This could be done, although It would be easier to install it in another chassis for sure, R700 or superliner comes to mind. anyways, first on the list is to move the cab back basiclly making it into a b73/75 configuration. To address the radiator issue using a later b73/75 alum. radiator and headlamp parts would take care of the hood width and cooling issues. The extra few inches need for the difference between the cat and the cummins could be fudged between engine placement and firewall massageing (read sledge hammer) or set the cab back farther and make your own hood. I have seen a b75 that has a detroit 60 series in it, I think its johndeere colors also, or at least yellow. Very long hood indeed. Lots of steering box mods also, I guess you could adapt and new power steering box and column while you are at it, posibily a first generation superliner front axle steering box combo. Not a chore for the faint of heart or pocket book!

Morgan

Rob, I am thinking that you will need to install a speedometer gear adapter inline, You know the little boxes that are usually stripped out and causing the speedo not to work on the old stuff. I think the "pencil gear" in the truck trans has very little tolerence unlike automobile aplications.

Happy b-day

Hey, Thanks for all the Happy Birthday wishes. I have to admit I have been neglecting my "online" time somewhat. I keep busy with my family and I have been working on an off breed (International r 205) restoration that has been in the shop entirely too long as it is. I decided a few years back to take on some side work restorations and I am having to use all my spare time meeting my obligations to them. In good time I will get to work on my own trucks someday..... I hope. Rob came over my way a week or so ago and had a good visit with him. I will not be able to make it to Macungie or Mass. this year due to rising fuel prices and non-rising wages. I am planning to go to Walcott this year and if they will let me in I want to take the superliner. I should have the engine repaired by then, inbetween working on these other trucks. Maybe I can convoy over with Ron,Mike and Rob( note to Rob... Keep one truck together and operational, otherwise I WILL BE FORCED TO bring a trailer in order for you to join in..) I also need to install a camshaft in to "aunt B" and find a doaner air compressor for it also. SO.... If anyone wants to take a few weeks off of work and come over to my place for some "R and R" (note.. that stands for remove and repair not rest and relaxation")we can fix you right up....

B61fred..... 40 years old, About damn time I reached the summit, I wonder if I got any brakes?

My b61 did the same thing, mine started at 42 mph and ended about 48 mph. I found out what it was by mistake though. The trunion stand bushings were worn out and the tandem would wiggle a little bit left to right. They should give a little in a turn. It would start an ostilation at those speeds and would shake pretty good then get less and less. I would imagine that it would come back at a higher speed but my truck was not capable of reaching that speed.

try the John Deere and Oliver rubber seat spring guys, The tractors from the late fifties used these rubber torsion springs and they are being reproduced. The ones from the tractor seats can be used with a little work.

I have an idea, Maybe if you would mark the back of the tire in four spots and drove it down the road with your camera. You might see that if say mark number 3 is always on the ground when the hop starts then you might have idea where to start. If the position of the tire has no bearing on the hop then you know to try another area. If its a rotational out of balance problem it should have a cosistant mark hitting the ground.
