Solution Summary: Shim Kit Available to Correct 400 Series Mast Claw Looseness on the Mounting Frame

Publication Date: Dec 18 2002
--------------------------------------------------------------------------------

**Paper copies of solutions may not be the most current solutions**

Complaint or Symptom: The loader is loose on the mounting frames. A gap is created through heavy usage between the square tubing of the mounting frame and the front pad of the claw retainer of the mast.


Problem or Situation: The contact surface area is reduced. Also refer to DTAC solution 43992 for loader mounting frame and mast adjustment.



Solution: Shim kit AW32306 is available from service parts beginning February 15th, 2003 to weld to the mounting frame to eliminate the gap and prevent looseness. Instruction W49388 is included in the kit.

Solution Summary: LOADER DOES NOT ATTACH TOTRACTOR PROPERLY

Publication Date: Sep 7 2004


--------------------------------------------------------------------------------

**Paper copies of solutions may not be the most current solutions**


Complaint or Symptom:

Loader does not attach to tractor properly. Loader mast is loose on mounting frame or front frame does not engage mounting bracket.

Problem or Situation:

Loader frames have not been adjusted correctly during installation.

Solution:

Using the following procedure, adjust frames to remove looseness in mounts or to allow front frame to engage bracket.

Detach loader from tractor.
Loosen rear frame hardware and rotate top of mounting frames toward rear of tractor.
Tighten hardware to specified torque.
Install loader onto tractor, allowing loader mast to rotate rear frames as loader rotates into position.
If masts remain loose on frames, repeat procedure, loosening hardware at mast arm to front frame connection to allow masts to rotate further on rear frames.

Additional adjustment may be obtained by enlarging rear frame bolt holes to 19 mm (.75 in.).

Also, slots in front latch AW29199 or AW29755 (depending on loader model) may be elongated toward rear of loader to allow further rotation of masts on frames.

AK; Evidently, there is a shim kit available from JD. The dealer explained that , due to loader geometry, it is critical to have the machine on a level surface to determine where to shim. There are four points of contact on each side and each wears differently. ( this is the part where my head starts spinning ). Their procedure is to weld the shims in place.
My problem is why should this have to be done with only 425 hrs.?
I remember looking at literature from JD, before I bought my tractor, explaining how the loaders are engineered for each unit and rigorously tested.
Seems to me they should last a lot longer without this annoying problem.

Your

- why should this have to be done with only 425 hrs.

I was wondering what do you lift with your FEL?

Can you shake both sides by hand?

I don't know why yours is that bad with only 425 hrs. and mine is
just a little loose, only on one side with about 802 hrs.

JD4300; The loader is used for snow plowing, bucket work with toothbar and with forks for logging. I am also suprised at how fast it is wearing. Both towers can be swayed back and forth.

Joec; Thanks for the info on the shim kits. It's probably going to happen one day.

Meantime I've come up with a very temporary fix for the winter using Simpson gusset plates. I bent them as shown in the pics and slid them into place bending the "tabs" over to hold them in place.
I only tried this on the front claw as these are the worst. I fit two in the right side and one in the left.
The loader stays on most of the time so the plates should stay ok.
It's too cold out to try it out today but I'll let you know how it works out.

I could only fit four pics on this post so I will do the rest on the next.

Here are the rest.

Please keep sending suggestions. Thanks.

There is a shim kit for my JD790. Has anyone actually done this or used one?

Update.

Well, I plowed last night and today. We got about 18".
The temporary shims took A LOT of the slop out of the loader operation. I was pleased and a bit suprised. They held their position just fine with vigorous use of the loader.
I am going to pick up a slightly thicker gusset plate and try and get it down to just one on the right side.

Good news! Any talk with your dealer on the factory fix? Or is it too spendy?

Last time I spoke with the dealer, he said that they could send their road service up to look at it and possibly install the shim kit here. He suggested I wait until there is another call in my area for the travelling mechanic to save on $.
I've had them here for warrantee work in the past several times and they are good.
We have not talked $ yet. I'll let you know what I come up with.

Hope you can get it fixed, if you could find out from the dealer

why it got that loose, would really appreciate the information.

 

[Chuck4310]

Just thought I would give you an update.
I found some thicker flat stock and changed the length and bends slightly to hold in position better. Works better with one piece of material on each side.
It also seems to have reduced the gaps in the other contact points.
This "fix" is only temporary, but it sure has tightened things up. I've been moving a lot of snow lately, and I can feel the difference.
