I have a 54d MMM mower (1023e) with the PTO shaft that must be engaged manually. I managed to break the joint on the mower gearbox and need to source a new yoke and cross/bearing assembly. Can anyone supply any part numbers or (even better) non JD sources? Everything I am finding out there is much bigger then what I need.

thanks

I didn't think JDParts would have this listed, but they do.

This is for the Auto-Connect driveshaft, but I'm sure they are the same u-joint.

So what I am after is the yoke (part of #6) in the 2nd diagram, but it looks like it's only sold with the shaft (which I don't need) for 170 bucks! (and that still doesn't include the cross/bearing). There has to be a better way to fix such a simple mistake.

Check with a local driveshaft shop they may be able to get you going.

You may be able to get away with something used off an old deck if you could find one and sometimes people have good luck going to a Kubota dealer with what they are looking for as Kubota seems to break things down more parts wise.

I bet the u-joint could be had from Tractor Supply, or any bearing shop.

u-joint failure - 60D deck on 1023e

Wish I would have seen this thread on my previous search after u-joint failure - 60D deck with mulcher on 1023e. Running RPM about 2500-2800. After stopping, and leaving the RPM full, engaged the deck with grass under the deck, and it sheared the shaft U-Joint. Called dealer and THEY INFORMED ME THERE WAS NO U-JOINT REPLACEMENT and had to buy the shaft assembly for over $500.00! After finding a shaft on eBay for $300.00, and quick delivery, installed the shaft. When looking for other deck parts for service, found the U-Joint part number AM131981, and ordered it for about $30.00 (price has gone up since original thread).
Installed the U-joint, but a pain, but now have a replacement assembly.

Recommend to users of a mulcher installed on 60D deck, engage the drive with the deck full up, low RPM, then roll up the RPM, will prevent the shaft from shearing, like others have described on this thread. Save time and expense.

I think I have found a few avenues to improve cost and availability of the solution. I have a 1023e with 60d and autoconnect. The slip-loc on the auto-connect shaft would stick open and I could close once on the machine. I clean and regreased to no avail. It appear the bushings in side the slip cover got out whack (but they also seem to float). The 90$ jd repair kit didn't work, I grinded the lip down on the yolk stem a bit and this got me through a season but next season back to sticking again. Went jd and best replacement they had was AM133971 for 300$ (it was half-shaft). 300$ every few year wasn't interesting.

So I got motivated and did some intereting.
I found the actual manufacture of the shaft /yolk/slip lock assembly. Company is Weassler. (found on an add for the repair kit on ebay). If you where really motivated you could likely order the entire shaft but I fould the just the auto-loc yolk end I needed.

this is thier catalogue https://www.weasler.com/wp-content/uploads/2016/05/North-American-Style-Driveline-Components-Aftermarket-Product-Guide.pdf
look for auto-loc
it's an auto-loc 101-0615 1" × 15 Spl. You can search this part and shows up at napa for 90$.

You can aslo find the manufacutre part number for the he repair kit Stock No. 13004015 Repair Kit for 1" × 15 Spl, it shows up at napa as well for 55$ (but photo seems wrong...hey it napa order and return if not right) but FC mason has it for 43$ and thier photo is more consitant with what I'd expect.
