55 Ton two truck climax

[BaltoOhioRRfan]

I was wondering if anyone had this problem with these engines. The problem is the gear box gears don't mesh with the drive line gear. or that appears to be the case.

Anyone know if the 70 ton climax drive line parts are intermixable with the 55 ton climaxes?

Some are and some aren't. I have used what is available from the Parts Store for the 3 trucker to indeed repair my 2 truck one. I had issues in the driveline with cracked gears. I remember studying the parts diagrams and seeing a lot of similarities.

Some parts fit, some don't. The basics are there......I even think the innards are interchangeable. I think the worm and bull gears are interchangeable as well. But I honestly can't verify this. Wish I could be of more help.

was tinkering around with em a bit today. just something doesn't seem right with the gear box covers. not holding the drive shaft in place correctly. I could get one or two running if i could just get the gears to stay connected in the gear box

I have the same loco,it's been sitting for over two years. I also checked out the gear box,i took a close look and it looks to me that the gear box casting is not machined or casted properly, plus the ash pan cover could have the same problem. This would cause the axel and bearing to move up or down and the main drive gear will not synchronize.I tried to put a shim under the ash pan cover to hold the axle closer to the main gear and replaced the ash pan cover, but the screw is to short,so i did not want to strip the screw by forcing it down, i gave up for now,what i did is to remove the gears from the trucks and let it free - wheel and push or pull it with another loco just to see it on the track.Just like running a consist. Also i sent it to Bachmann they wanted to send me a 3 TRK, but i have two already but i asked them to send it back to me.
