 LA352 Loader bushings loose

My LA352 loader is about 1-1/2 years old, and has about 200 hours on the tractor. I've recently noticed that the bucket pins are getting REALLY sloppy. I haven't disassembled the joints yet, but assume there are some bronze bushings in there that have prematurely worn out. Have any of you experienced this? What is the typical cost for the parts to repair (ie, is it cheaper for me to pay for parts instead of transporting to the dealer)? This is primarily on the cylinder joints.

BTW, these joints have never been dry. They are greased very frequently.

I haven't seen that problem before. Not to say it can't happen but it is not the normal for sure. I'd be looking for something to be out of aliagnment.

Ok, I just got a chance to pull the pin out of one of the cylinder joints. There are no bushings like I am familiar with--just a pin. I stuck the pin in the bucket joint only, and it was very sloppy--probably 1/64" movement on both sides. Then I stuck it in the cylinder, and the same thing. This adds up to what looks like a little more than 1/32" movement in the joint. When the bucket is fully curled, this slop translates into quite a bit of bucket movement.

I looked closely at the pin, and there is definitely wear (polishing), but nothing really stands out. I guess if Kubota had intended this to be a tight joint, they would have machined it to tighter tolerances. It's not unbearable--I just don't want to cause further damage by ignoring what could be a potential problem.

To have it much tighter might cause some problems for the people that might not be as meticulous as you. It's a fine line for the manufacturer to have the pin hole tight for those that are greased regularly vs those that don't and the pin siezes from lack of lubrication. I'm going to be checking the ones we have coming thru the shop for service.

Meta, your comment "They are greased very frequently." made me think, never a good thing, Laughing out loud .....

What type of grease are you using ?

We have found that some grease is much stiffer than others, on joints were there is significant 'pinch pressure' if you use a light grease it gets displaced by the load too easily on things like the FEL.

Try using a much stiffer grease like the stuff they sell for heavy truck suspensions.

We have two sets of grease guns for our units, one with light grease for lube only, and one with very heavy grease for FEL's and other 'extreme' applications.

Best of luck.

I've been using a thicker Chevron grease (red), but I can't remember the specs on it at the moment. I like to grease the joints after doing any significant loader work since it helps displace dirt/water. That means I give them 2-3 pumps probably every 5-8 hours of loader use instead of the recommended 10 hours.

Do you guys have a grease that you would recommend over others?

I appreciate your help Art/Murf.
