Otherwise, the set up worked the same and the brake linkage was the same.
IOW, the entire set up was exactly reversed from the configuration on the left clutch and with a strange right angle ball joint to boot. The fine threaded adjustment rod with the right angle ball joint was attached to the clutch throwout lever - but the ball assembly was much larger. Today I pulled the cover off the RIGHT steering clutch (for comparison) and, lo and behold, the entire configuration was DIFFERENT! The spring loaded ball joint coupling (AT 17365) was attached to the RADIAL arm linked to the steering lever (vs the clutch throwout lever as on the left clutch). Separate subject: All my previous posts on this subject dealt with a problem in my LEFT steering clutch. 350 - LOADER, CRAWLER 350 Crawler Tractor - PC921 350B - BULLDOZER 350B and. Maybe the design engineer for the 350 thought you need fine adjustment on clutch links? design engineers can be a bit anal like that.

I always thought these kind of threads were used on machine tools such as lathes for fine adjustments. None of it makes sense for use on a bulldozer. I can also tell you how I got the broken ball stud out of the steering lever but all that might be more than anyone wants to read in one post. Why does that ball coupling seem prone to break and why did JD use machine threads on the adjuster rod? I have theories for both if anyone is interested in hearing. There is no force pulling against the threads at any time during normal operation. Of course that weakens the thread structure in the coupler a bit, but the new jam nut (a standard 3/8 fine thread) should take most of the pushing stress when you activate the steering lever as long as you snug the jam nut against the adjustment coupling (17365). Great Idea but very hard to get set properly.
When they came with the wet brakes they installed an automatic self adjuster. You will see under the seat the 2 spools for the clutches, usually you do not have to do anything there. The tap went through easily since there is not much difference in the pitch (24 vs probably 28).

The 350C has wet steering clutches and brake band. My solution (after lengthy discussion with my JD parts person who couldn't figure it out either) was to run a 3/8 - 24 tap through the clutch shaft coupling (17365) and rethread it. If you lay the old and new parts side by side, you can barely see the difference, but it becomes obvious when you try to put the old jam nut on the new adjuster rod or screw it into the clutch shaft coupling (PN 17365). The new part has standard automotive fine threads (3/8 - 24) on both the adjuster rod as well as the ball side that screws into the steering lever. The problem is the old L shaped link with the ball and socket (PN AT17364) has a different thread pitch (smaller, machine thread I think) on the adjuster rod than the part they want to give you to replace it (AT317916, I'm guessing). Tests and adjustments, required to keep the tractor operating efficiently, are explained in detail.Been there, fixed that - just yesterday (I think). Dimensions of many new wearing parts are given as an aid in determining when parts replacement is necessary.
