 FEL Hydraulic Problem

I have a JD 4300 with about 200 hrs hat has largely been a lot of trouble. One of the problems is the loader hydraulics - they keep breaking. The first time was the weld on the rear hydraulic cylender shaft - it just broke off. Another time the front [bucket] cylinder started spewing fluid. Yesterday I was moving some dirt and the bucket started sagging. And then it just dropped. The shaft that lifts the bucket broke in half in the middle [inside the hydraulic cylender] and the weld broke on the other side. I did not think that I was abusing it or being hard on it. Has anyone else had problems with the 420 hydraulics or is it just me.

 FEL Hydraulic Problem

From the description, I guess that you're not driving head-on into gravel piles at speed or using the blade like a dozer or driving through big tree roots etc. There are uses that no design of realistically priced equipment is going to handle without breaking. Anyway, I think of abuse as a relative thing--use for which the equipment isn't designed. Generally, if you pay more for a piece of equipment, you expect to get more features or you expect it to be more rugged or durable. More rugged equipment has less scope for abuse. So, a curious possible conclusion from all this is that the more that is paid for equipment, the less it can be abused--not that I think there is abuse of the loader in this case. In general, loaders rely on the system pressure relief valve and relief valves in the loader SCV to protect against over-loading. Granted, the attitude of the bucket can magnify the weight of a load on various components. However, I'd expect the engineering design to be such that the loader cylinder shafts can withstand loads that don’t trigger the relief valves. Of course, it is possible in float to run out of cylinder travel and have no protection against breakage except the strength of the steel parts. However, for the most part, I expect an implement to be able to manage what ever the hydraulics are capable of. However I do recall a discussion that might be relevant. The discussion was about bent or broken cylinder shafts. I think it was backhoes and JD equipment, but I'm not sure. Several people had heard that a production run of cylinder shafts was inadequately heat-treated and were subject to failure. I'm just passing along what could have been a baseless rumor, but it might be worth checking.

Doug;

I was the person with the bent backhoe shaft, it was on a JD #48 hoe. It was replaced under warranty. The local JD rep. stated JD was having "some" problems with improper heat treated shafts. I don't know if it was with all shafts or just the ones that were used on the #48 hoe.
