Nope, everything looks good. The trans has been replaced by the previous owner. I am wondering if the bellhousing, trans case, or rear mounts are different.

Me likey

I need to find that guy.

It is a 685 with the original 237. What are the differences in the chassis? I am having a strange engine mount issue. It has been like this since I bought it, and I am finally getting around to fixing it. The snout on the front cover does not go all the way through the front engine mount. The rear isolators were worn out and allowed the engine to slide back a little. When I replaced the rear bushings, I also did the front. I put a portapower on the trans to push the engine/trans as far forward as the rear mounts would let it go. It is not far enough. The balancer is still right against the engine mount. I believe there is a difference in the distance from the rear mounts to the front mount on an RL vs a standard R. I have no way of knowing for sure.

Hey guys, I am new here and needing some info on my old Mack. What is the difference between a 600, 685, and a 700? I am having an engine mount issue.
