B21 loader bucket slop

[Leozepolusa]

Hello,

I recently purchased a 2005 B21 (994 Hrs) and would like to get rid of the slop I have at the loader bucket pins. I've roughly measured the specified I.D. and O.D.'s for the links, boom, pins, etc. and there seems to be some degree of wear throughout although not more than about 1mm. However, combining the wear on pin O.D.'s and link/bushing I.D.'s yields double the slop. There are only two bushings on each side at the boom/link locations to replace which leaves only pins to replace everywhere else if I want to avoid a big expense. I hope replacing only the pins and bushings will substantially solve the problem. Has anyone done this with good success, or am I likely faced with a big investment to fix this? If the problem persists after installing new pins & bushings, does it make sense to just live with the slop and let the cylinder, bucket, and link pin sleeves continue to wear down?

Thanks,

How much slope do you have IE does the cutting edge move 1/4" or 4", all buckets have some play but with only 1000 hrs I wouldn't think that you have that much.

It appears that I have approximately 1.5 inches of slop at the cutting edge.

Be sitting down when you get the price on pins. I replaced one pin on a B21 backhoe bucket about 6 years ago and I recall it being $28 dollars. You can go to TractorSmart.com is your online source for Kubota online parts. and and they will send you a pfd file of the B21 parts manual.

Second that on the price - $22 for the pin and $40 for the bushing.. My B21 with 320 hr has maybe 3/8-1/2" slop at the edge mostly from the bottom and top pin on the bucket where it sees the most dirt/abuse. My BH bucket is looser than the loader since I use it more but decided to wait for another summer of use.

I would do the 4 bucket pins and 2 bottom bushing on the boom then go from there.

I have same problem with L48s, top bucket pins wear fast due to dirt build up. I broke one and it was alot more than that, I think $50-60. I have broken the bucket pin on my KX121-3 2X and it is $181. Ouch. I always grease the piss out of the loader pins to push any dirt out.
