Loader Repair vs replace bucket links

I'm curious what a $160 bushing looks like. It must be plenty fancy.

I'm curious what a $160 bushing looks like. It must be plenty fancy.

Knowing Kubota it probably looks like a steel insert bushing, bored for the correct sized pivot pin.

7J275-64510, NLA from Messicks but Coleman has 2-5 day lead time. Note that it says it is for an LA844, so no guarantee it will fit properly.

Yes, it should be fancy, alas it will likely just be a soft sleeve. I do plan to press one of mine out to confirm ID and OD, in case some handy person would be inclined to turn me one or two from a 660 rod/tube. Or, if we're really lucky one can be found at McMaster.

This also doesn't address the play at the bucket cylinder tube end, however.

Been getting replacement parts I need from Coleman's right along. Their shipping is less than Messicks (unless I can order what I need from my dealer) and they ship very promptly as well. Some stuff I really cannot make in the shop at any savings. The dog bones (parallel linkages) are a different story however as well as the bushings and pivot pins. Steel, in general has become quite expensive today and alloys like stainless and aluminum is even more. I do have a pretty large inventory on hand of bar stock and ground bar in mild steel and stainless. Thank the lord for that. Until something gives with the economy, I dread buying any.

The plot thickens

7J275-64510 discontinued by Kubota although some dealers still have stock
It's used in the following FELs

​

LA1055 LA1055-50

LA1065 LA1065A

LA854 LA844

7J275-64510 has associated part number 116060040 which may be the manufacturer's number but web search results in no additional information

Looks like we either need to bite the bullet and pay $300+ for a pair of $5 parts, have a set machined which entails one of us obtaining dimensions, or live with bucket slop

OK, confirmed some measurements:
OD of bushing is 1.500 +/-0.003"
OD of a new pin 7 for this link is 1.185"
ID of rod eye is 1.497"

I fumbled around with this set to get the bushing pushed out about 1/2" to measure it and the rod eye: Powerbuilt Ball and U Joint Service Set, 23 Piece. The bushing would jump about every 1/2 turn of the wrench, so it was in there good.

As of right now I'm looking at getting 13" of this and shipping it to my brother with a lathe. OD will need to be turned down and the ID will need to be increased to an appropriate dimension, likely 1.190 to 1.195". If all goes well, we should be able to generate 4 bushings at 2.20-2.25" each, with material left over.

In other news, as noted previously, the cylinder barrel pin also has some play, note the pin does not rotate in the weldments as it is bolted on the far side.

Sounds like a plan. Once your brother gets set up he can probably make coffee can full of those bushings in not much more time than making four for you. Especially so when the ID and OD are already so close.

It's nice to have a little bit of machine shop capability at home. Even nicer when retired, as it gives old friends an excuse to stop by, use the tools, and share projects.
