51 B transmission

I have the service manual for the tractor, which seems fairly clear about how to dissasemble and reassemble.

The service manual mentions that a lot of the cap screws are held by mechanics wire. What is this, and how do I get some?

Thanks,

Kurt.

Read and follow the manual ( hopefully you have a JD one ) it will walk you through tear down and set up and adjustments.

Is JD the best place to get all the bearings, or can you recommend a anternate supplier?

I completely rebuilt my B transmission recently. The manual is very helpful and will walk you through it. I got most of my bearings from JD because the price was competitive. Once you pull some bearings out your will probably find Timken or New Departure numbers. You can use those numbers to get competitive prices.

The worst part I found was removing the bad races and bearings out of the housing and off the shafts.

If you have a bad bearing race the easiest way to get it out is to use an arc welder and weld a bead around the face. It will drop right out. A slide hammer works well too. Heat is your friend.

I have found, for every situation there is a tip or trick to help out.

Did you by any chance keep a record of the bearing numbers?

Thanks,

Kurt

My B is a 1940 which is a 4 speed. Would have to do a close cross examination of the parts book. From what I remember, the parts in the main case are mostly the same. Your 51 has two more gears on the left side external to the case under a cover.

I will take a look and see what bearings are common and send you a list.

What did you use for the mechanics wire the service manual mentions passing through the drilled heads of the various cap screws?

Kurt

The purpose is to prevent the bolts from loosening; this is used extensively in aircraft. When wrapping the wire, think about wrapping it to keep the bolt tight, tying in that direction. Look at how the factory did it, and follow their example.
