That's what it sounds like to me too Mike. Ron

Carl, I think the bolts you are looking for are known as step bolts You can't get them at your local Home Depot but any industrial supply should be able to get them for you. Ron

Congratulation Mike, good luck with it! Ron

You said a mouthful there Mike! Ron

For 11-22.5's you would use a 22.5x 8.25 rim. Can't answer your other question. Ron

What Vinny said! Ron

That B-813 sure looks familiar, I bet Matt Pfahl knows every nut and bolt on it! Ron

Sorry Doug, I thought he needed some company, and I couldn't resist! Ron

Congratulations! Ron

The later "MH"'s rode a lot better than the earlier ones. There were three different designs for the cab pivot bushings. The first ones like you have are metal threaded pins into metal threaded bushings. The last style were rubber sleeved bushings (like the old control arm bushings in 70's cars) They were believe it or not the same exact pivot bushings that were used in the last "F" models (Interstaters) We had four of the older style 2 were '85s and 2 were '87s. When the last two came which were '93s the difference in the ride was unbelievable. I converted three of the older ones over to the latest style. I don't know if there are any of the parts still available to do this and it was to say the least a lot of work. The parts needed were the two pins with lock nuts and the two bushings, that was the easy part. The hard part is that the frame brackets along with the knee brackets on the cab have to be machined to accept the new bushings and pins. If you look at later "MH"'s you'll notice how the headlight panels in the area of the pivot bushings have an extra cutout towards the outside, that is to accommodate the later pin arrangement. There was a service bulletin explaining how to do this. Just thought I'd throw the idea out there. Ron

You're right Neil, he bought a bunch of stuff from us. Ron

I re-read your post. The cylinder your talking about is only on the right hand side and in actuality is the safety prop. It keeps the cab from going all the way over and also has a latch mechanism that keeps the cab from falling once it's in the service position. These cabs will only tilt to the service position, they were not designed to tilt to the full 90 degree position. Ron

Nice looking truck! The first "F" models did not have hydraulic cab jacks. They had a torsion bar lift system. Those two round castings at the hinge point between the cab and bumper are where the torsion bars are located. More than likely one or both of them are broken. Anyway to tilt the cab you have to unlock the cab using the handle inside of the cab. (looks like the emergency brake handle for a "B" model) It's at the back of the cab in the center. The safety catch release is a cable that you pull located at the R.H. door jamb, it's cable with a loop in it. After the main lock is unlocked you pull the safety catch and manually push the cab up. Make sure the gear shift is in a gear that will clear the opening in the cab when you raise and lower. It will probably be extremely heavy due to broken torsion bars, but it could always be worse, could be a sleeper! The torsion bars for a day cab and a sleeper were different due to the big difference in weights. I have know idea where you could find replacements, but you have to get the cab up first before you can replace them anyway. Ron

Welcome to the nut house! Ron

Happy Thanksgiving to all my friends on BMT I wish everyone a safe and happy holiday. Ron

Don't think I've ever seen a truck with dual Farr air cleaners on it before! Ron

Congratulations Leslie! Ron

Invoice to follow! Ron

Don't know whether this was just a rumor or not but I'd always heard that the New York State Police bought a bunch of '59 Chevys and much to the their disappointment found that at very high speeds they would actually tend to lift in the rear end. Ron

They're 9670's Ken. Ron

Ken I'm not sure but I don't think Martins ever had 4070b's, but I do know by '93 International had discontinued the 4070's and was producing the 9670's. Ron

1,400,000 miles, just broken in! Ron
