Warning about tweaking the 419 FEL

[tomrscott]

A service tech at a local JD dealer, a guy that has been pretty helpful, while we were talking about the loader, happened to mention to be careful when lifting something heavy, especially trying to get something unstuck, that it is important to get a straight bite on the object so that the left and right arms lift approximately equally.

He said he has seen a couple 419's come in with a permanent twist in the loader frame from putting extreme uneven stress on it. He didn't really know exactly what the guy was doing when it got tweaked, but it may be worth being careful about. This is out of hundreds that this guy has probably seen, he has seen a couple, so it doesn't sound like a terribly chronic problem, but I respect the guy enough to pay attention.

He did say that one guy had tried to jack his 790 hydraulics up to something like 3800 psi and that was undoubtedly one of the ones that got bent.

This might be particularly worth paying attention to if you put in a pressure relief shim kit to raise the hydraulic presssure even to 2500.

For whatever it is worth, I'm going to be kind of careful about lopsided lifting. YMMV

I have a 4310 with a 420 FEL , I have about 50 hours on it since new. After taking deliver and getting it home I notice that the bucket was not parallel to the ground. The right side is about 1 ½ lower that the left. I have tried to adjust the loader support brackets and have not been able to get the thing level. I wonder if mine is tweaked and if so would the dealer warranty it? Or is it normal for the bucket to not be parallel with the ground?
Thanks for any input.

"I have about 50 hours on it since new. After taking deliver and getting it home I notice that the bucket was not parallel to the ground."

First, check your tire pressures all around. It doesn't take much difference (in pressures) to make the tractor appear "twisted" or leaning. When I noticed the ROPS was on a distinct "list", none of the tires appeared low, but one was...

Unless you know your ground is perfectly level and flat, you really don't know if you have a problem. Using a 6 foot straight edge and a level to determine how flat and level the area is can give you a reasonably good reference surface to work from.
Then you can determine if you even have a problem, and a good surface to work from, should any corrections be necessary.

As with any mechanical device, it's important to distribute the load as much as possible. If you put all the stresses on one corner (using one bucket hook on the end of the bucket instead of using both outer hooks with a properly rigged chain or strap, for example), one risks over stressing the components of the loader on one side of the tractor.

Thank's for the warning Tom .... you know a little common sense and caution goes a long way /forums/images/graemlins/crazy.gif.What did the JD man say about shimming the hyd???
