Thread: Wrong yoke for my TH400? Counterbore?

Tweet

Okay all - one more question. Before I purchase the $100 "counterbore" yoke, I decided to pull the tail off my tranny and see what was causing the yoke to stop it's travel. Turns out that the threaded shafts have a metal shoulder about 1/3" wide with an o-ring that is stopping the yoke from going the full length onto the shaft. I'm thinking about pulling out my p-grinder and smoothing out the metal shoulder, which would allow my yoke to slip in all the way and I likely wouldn't need to have my driveshaft shortened because of the extra slip it would give me. (It would also save me $100).

Anyone know of a reason why I shouldn't do this, or problems it may cause? I wouldn't think that by smoothing this out all around the shaft I would cause any balance issues.

Thanks...

Hobo, think about the torque that twists the splines on the yoke....now think about your grinder leaving nicks or stress risers in the shaft....what you would be trying to do is to make a lathe part using a hand held grinder!! What if you screw up and the shaft breaks? Is that a $100 error? What if the shaft breaks and the yoke goes sideways and takes out the transmission tailhousing/case? That may be at least $3 alone..... If you're asking, my advice is to pony up the $100 and do it right.
