Bucket tilt

[eddieirvine]

i bought my Kubota 3940 about 5 years ago it was used when i bought it. the bucket when laid down on a level surface has always been off, i would say 2" on the one side. My question is what is the best way to tweek it back close? I know i have seen post on this before but cannot find any. Thanks

before you do anything drastic, make sure its not a simple issue like tire pressure. Especially with ballasted tires, a little pressure makes a big difference at least on the little one like I have. L is much larger but couldn't hurt to check?

I agree with checking the tire pressure first. If that’s not the cause try removing the bucket and chaining the high side to a stump and lifting.

After checking tire pressure, measure from axle center to ground on all four. A replacement tire, even if the same labeled size, may be a different physical size.

If all match, then you need to determine if the bucket is twisted, or the loader is twisted.

Also check the mounting hardware before trying to bend anything "back", I had to do this on my B, doesn't take much on the mounts to show up on the bucket.

tire pressure is good on all tires, i will start with checking all bolt connections and do some measuring from both sides, like i said it is not much but when you try and level ground dirt it drives me crazy thanks so far for the ideas

I think a 2" tilt huge. If you try to scrape up something on a cement floor, you'll end up with a groove in the floor.

With the tolerance stackup of all the components in a loader and frame, there must be some adjustment provision at final assembly. If I can find my 753 loader manual, I'll look.

well worked on my bucket today measured everything on the tractor tiers are all the sam brand and size air up to specs, it is not the bucket measuring the two quick attachments right side sitting on the seat is lower, so took and chained the left side to a stationary pole so it would not move, used a floor jack on the side that was low and gave it quite a bit of twist, i though i might of went to much but got it all off and checked it again i gained and inch and a quarter, it was off 2"now i am about a 1/2 off still but that is ok,i get some spare time whenever that will be i will tweck it some more, i took measurements on how much i raised it with floor jack so i know would know where i was at. I also talked to a friend of mine at John deere. he said they get them in all the time, usually they chain them up and do about the same thing but have a hoist they use

1) There was a very similar post within the last month or two -- some guy had a tree fall on his and bent the loader so the bucket was a few inches lower on one side than the other. Lengthy discussion. I bent my own (Massey Ferg 2660 and DL250 loader) doing dumb things prying on a locust tree stump... and then bent it back toward level by using the same sort of reversed off-center forces. BY THE WAY I can find no manufacturer who has or will share any data on torsion in FELs. The Nebraska tractor lab does not either.

2) Can you clarify how you rigged a chain and a floor jack to put corrective torsion on the loader ? I cannot picture that.

3) Good idea to look very carefully for paint crinkled off of welds and any other indications of damaged welds.

I am trying to download pictures on this post? I have done it before but i find my picture in browse when it comes up and hit download and nothing happens

 

[eddieirvine]

That worked ok but sense had a different set up

This is my second attempt and it worked great took bucket off again and stabilized the other arm against a tree and raise the other arm that was bent low up until i thought it was enough. Three attempts and measuring each time from a know part on the tractor arms it is right on now!! Happy camper

Picture says it all. Very good. Innovative way to put torsion on the loader frame for sure. I do not have a come-along anywhere near strong enough to do that "correction twist" on my larger loader but the idea is solid. In effect simulating a frame straightening machine.

Of course there is some risk involved doing that sort of thing (damage to the loader) but it's pretty darn practical. One thing I like about that technique is that once the loader "gives" some, there is a greatly reduced force from the come-along -- e.g. it does not keep pulling way beyond the correction you control.

By the way, this correction torque is limited to whatever it might take to turn over the tractor. Sounds silly but certainly true.

chance of turning over the tractor is not a problem, you would never go that far with com along to tip it, especially securing the other loader arm to the tree with a chain, have to find two tress with a good span to line up arms, other than that crank the handle inn check a known place to measure from and you will get there. i have a smaller come along 3/4 ton that would have worked but put it to max and was not enough, i bought a ton and a half made the job very easy, more tork and longer handle for more control.
