Reversing Gear Yoke
I am in the process of reassembling my A4 and have come to a crossroads involving the Yoke and the Cross Shaft.
During the disassembly and inspection, I noticed some wear on the Cross Shaft from what appears to be from the set screws. This also looks like a possible source of a problem related to the shifting arm and the over-all adjustment to the reversing gear. When I reviewed an old Universal parts manual, I discovered there were keys preventing possible movement of the yoke on the shaft. The manual calls for a total of four of them. That said, there were no such keys when I took the Reversing Gear apart (PO removed them?). In addition, I find no such keys for sale on the Moyer Site or in the Overhaul Manual (perhaps I was too tired to see it). Bottom line. While even the new Stainless Shaft shown in the online catalog shows cut-outs for keys for both the shifting lever and the Yoke, where are the keys and/or how do I get some if i truly need them. Is it as simple as heading for a machine shop or does Don stock them?

Tritonfl,
You definitely, without question, need two Woodruff keys to secure the shifting yoke to the cross shaft. The Woodruff keys measure 1/8" thick and 3/4" across the top. The bottom of a Woodruff key (in case you're not familiar with them) is round. Woodruff keys should be available at any local machine shop for a couple cents each. I'm amazed that the reversing gear was functional without these keys installed. I would never have thought that the set screws alone would be strong enough to withstand the rotational forces imposed on the yoke during shifting. When you install the shifting yoke, be careful to have it centered over the round cut-out on the underside of the shaft. Don |
