David Posted April 2, 2011 Share Posted April 2, 2011 Are there places that the fiberglass cab in a MH is prone to cracking?Thanx . . . .I've never seen any problems with the cabs. The plastic grills and the bolt on front corners with the headlite housings are another story. Also the aluminum steps are prone to breaking. We've parted out some MH's that probably had a million miles on them and the cabs have always been in one piece.

Firemack Posted April 2, 2011 Share Posted April 2, 2011 StevMy MH 612 has 1.7M miles and has no cracks on the fiberglass cab, It does have some wear and tear around the edges of the doors and step, but nothing more than 1". I have a 66 vette and has way more cracks than the MH.

I've worked on literally dozens of them as it seems I always got stuck with the "plastic fantastic" of the 1960's. I've never seen an "MH" series cab cracked from anything like normal usage, but have repaired a few "deer hits" and they are not a difficult truck to work with. The most difficult part was the usage of ladders and lift apparatus needed to work high on the cabover design.Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

mack mhe9 Posted April 3, 2011 Share Posted April 3, 2011 from what i was told the first and second years would crack above the rad tanks, front side of the dog box, was quickly fixed by mack with a new cab, my old boss worked a truck shop in denver pa and said they would take the cabs apart get the new shell reinstall everything, put the old cabs in rolloffs and away they went, cant verify but he wasn't into bs, ive owned 2 84s with no cracks.

GearheadGrrrl Posted April 3, 2011 Share Posted April 3, 2011 I've seen a lot of UPS MHs with over a million miles on them, no cracks in the cabs and still tight. Only problem I saw was the doors sagging a bit... Easily fixed by lifting up while closing the door!

BAD DOG Posted April 7, 2011 Share Posted April 7, 2011 Those MH cabs are tougher than iron. I had one that was in a really bad head-on collision and jack knifed due to the pitman shaft being snapped off the steering box on impact, it took a hell of a beating, and I think it could have been fixed but the frame had too much damage. It would have required a total rebuild. I also scrapped one for parts one time I spent a lot of time beating it with the backhoe so I could dispose of it.
