Popular Post mackmb212 Posted January 4, 2015 Popular Post Share Posted January 4, 2015 So I finally really starting working on my truck. I have it about 90% tore down to the point I can start repairing and putting things back together. I found a lot of cracks and cracks that have been repaired already. The most interesting one is 4 inches long and in the side of the trans. 13 Quote Link to comment Share on other sites More sharing options...

Can you tell if there's any damage? yes it's a dubble overdrive quad box. I had 2 friends of mine check the trans out, took off top cover and everything looks good. I got to run the mine box through the first 3 gears and it seemed fine. 1 Quote Link to comment Share on other sites More sharing options...

Wobblin-Goblin Posted January 4, 2015 Share Posted January 4, 2015 Is this the B81 that was for sale (in NJ I think) a few months back? Quote Link to comment Share on other sites More sharing options...
Gmerrill0516 Posted January 4, 2015 Share Posted January 4, 2015 I remember seeing this one advertised for a few years. Gearharts or truck paper or somewhere. It was on a site that had some other heavy equipment as I recall. I'm glad it is getting some love. I'm still hoping to get some floor space under roof again so I can finish mine up...maybe 2015 will be the year. Quote Link to comment Share on other sites More sharing options...

mackmb212 Posted January 5, 2015 Author Share Posted January 5, 2015 The sad thing is most of the sheet metal you see in the first picture is junk. Out of everything the passenger door and the passenger headlight bezel are the only things to get reused. Quote Link to comment Share on other sites More sharing options...

mackmb212 Posted January 6, 2015 Author Share Posted January 6, 2015 I took a few more pictures today of some of the cracks and a busted bolt.The crack in the trans is more then just what I thought, it appears there is a whole piece that broke out and they fixed it with some epoxy that I thought was just a glob of grease. On the plus side all the gears look good in the main box and auxiliary.The main bolt that goes through the rear leaf spring pack is rotten and broke, I was really hoping not to have to take the back end of the truck apart but it looks like there is no avoiding it.If anyone has a b81 tractor or had one I need a official dry weight. Pennsylvania requires it on the title and the out of state title I have dose not show a weight. I had a b61 tandem axle,double frame and a paper under the seat said it was 10,500 so I can't imagine the b81 being much more then 20k.

1957B61Vt Posted January 6, 2015 Share Posted January 6, 2015 So what do you think Caused the crack in case?Water froze and cracked?Or previous transmission failure?Looks fixable though . Quote Link to comment Share on other sites More sharing options...
Brocky Posted January 7, 2015 Share Posted January 7, 2015 That close to the bottom I would say a water freeze??? A lot of old farm tractors had this kind of "blow out" when parked outside and rain came in thru the worn out shifter boot. 1 Quote Brocky Link to comment Share on other sites More sharing options...
Maddog13407 Posted January 7, 2015 Share Posted January 7, 2015 yup, agree looks like a water push out. good welding shop can weld that right up with cast iron rod. I have seen a few Mack trans broke in this same spot actually. mine has about 15 pounds of brass on it. I ended up changing out the front case with a spare. glad to see you moving along on this gem and decided not to sell it. 1 Quote Link to comment Share on other sites More sharing options...

I'm guessing a failure and maybe they were in a hurry so they just fixed the internal problems. 1 Quote Link to comment Share on other sites More sharing options...

mackmb212 Posted January 7, 2015 Author Share Posted January 7, 2015 So I found proof that some people should not be allowed to work on trucks.this is where the generator bracket should mount. Quote Link to comment Share on other sites More sharing options...
