LA434 loader freeplay

[thebicman]

Have a B2601 with the LA434 loader. While installing loader this weekend I noticed a lot of play in the upper loader boom. I'm assuming there should be very little slop if I move boom side to side with weight off pin. Asking before I remove loader to inspect. Always grease and just over 100 hrs.Thanks.

Is it easier to remove and inspect pins with loader attached or not?

The play you should be concerned with is back and forward.

Side to side play is normal and allows the loader to center itself in the frame which is bolted to the tractor.

Doubtful you have any issues!

Good to know. Thanks. If I did want to remove upper pin should loader be installed? Looking at it I would think all load is removed from upper pin if loader is installed and bucket down.

Installed, but be careful as it can shift when you pull the pins.

I have a 2019 B2601 with LA435 loader, at under 200 hrs. loader arm would occasionally disconnect from the loader quick connect frame. this is the reply from kubota.

changed all fluids and filters 2 times 50 and 200 hrs. grease all fittings 3-4times a week depending on use. the part with wear does not have a grease fitting. looks like a bad design!

How does the pin secure to keep it in place? The older ones have a little sliding pin that fits in a hole in a bracket. It can’t come out.

I have a 2015 B3350 and it has the pin retainers, I was also looking at the thickness of the steel that the pins go thru, looks like 1/4”, straight as an arrow, and i beat it up pretty hard last summer building a rock wall, dragging and pushing hugh rocks around.

LA435 on the 2019 has a quick connect feature only had the loader off 2 times 1 to take pictures to send to dealer and 2nd time at the dealer. so they could take more pictures. It looks like a piece of pipe approx 1 " long on each side welded to the loader arm that fits inside a locking collar there is no grease fitting and does not show any lubricating point on the owners manual. Have moved approx. 100 10 yrd dump truck loads and dug up approx 6 tree stumps so far. approx. 220 hrs on tractor so far. No problems with mower so far.

There are no grease fittings on that pin because there is supposed to be zero movement at that joint. From the pictures you show of the wear on the mount, something obviously went wrong, there’s too much movement at that joint. Looks like quite a bit of metal on metal movement. I suspect the loader wasn’t mounted correctly or something is out of spec and the loader mount isn’t matching up with the loader arms. There shouldn’t be any wear at that point at all.

The side that is worn looks like your back blading a lot?

I have seen it happen on bx's. Specifically the BX bulldozers.

Basically, it's the same thing I've been saying for many years. The tractor has limitations and a BX is a glorified lawn mower that just happens to have the same features as a bigger tractor; but it don't have the robustness as a bigger tractor. IOW, asking too much of it WILL result in weird stuff happening.

Now they're putting QA loaders on B series and similar to the BX, if you ask too much of it, it's gonna let you know.

Lastly, that's gonna have to go back to a dealer for them to inspect and make a call to the warranty department if you want warranty to help you with it. Contacting customer service is generally a waste of time, as they do not have the tractor in their posession, no way for them to know what's causing it if it's not there in front of them for them to see all of the components.

On the BX's if you don't have the loader levers TOTALLY locked, the loader will come off when you put a load on it. I don't like the design for that reason; in addition exactly 0% of owners will actually check the lock levers during operation to make sure something didn't pull one of them loose.

I don’t really like those QA loaders, mine is the old style with the big pins you slide in the side, there’s no way it’s coming off.

Both sides are worn about the same. most of the time was moving dirt and tree limbs, brush and firewood. approx 50 hrs digging with backhoe. have not noticed any way to adjust movement of the arm. Any ideas would be appreciated Thanks

I have a much bigger machine but I have slack in the mounting pins too. I drop some 1/4" angle iron in the top. It takes up 75% of the slop.
From your picture it looks like you have the wrong size pins in the holes. Either look up and get original pins from a dealer for it or measure the holes and see what size is closest to the size you measure.

What pins? Are you perhaps seeing THRU the hole and the background steel appears to be a pin?
