Wheel Motor Leak

J_J · May 16, 2006

They make a 60 in for the 1430 which would probably work.

Got the wheel motor off last night. Boy what a job. I tried to use a wheel puller to get the hub off and ended up breaking the puller so I took the whole thing to the hydraulic shop today. The 4 bolts holding the motor in place were nearly welded on with rust and I had to use a small sledge tapping the wrench to get them to budge.

The owner of the shop looked at the motor for maybe 2 seconds and said "it's a White (brand) low speed high torque wheel motor" without me telling him anything. I was impressed. He said he could determine the remaining specs once they opened it up.

He spun the shaft by hand and said he felt the motor had severe wear internally. I think he was surprised when I told him it was only 4 years old and maybe 600 hours on it. I asked about replacement cost and he quoted around $400 for a new one. They charge $60 per hour shop labor so it may be cheaper to buy a new one that rebuild the old one.

If he was surprised as to the wear after that many hours I wonder if he can identify why it deteriorated in such a short time frame? Is there something we can all learn as to preventative maintenance that perhaps we are not doing now?

Bob,
I took the wheel motor into a hydraulic shop last week. It took them a week to getting around opening it up. They also had a hard time getting the hub off so it wasn't just me!
They said it did not look too worn and just needs a new seal.
Problem is, they can't find the exact specs in order to get the correct seal kit. Does anyone know the model # of the wheel motors used on a 425 built in 2002?

You must have missed my post about getting the seal from PT and taking the motor in for a reseal. Post #884990 PT will probably have the fight one. The hyd shop may only be guessing. PT does things this way for a reason. You have to purchase the parts from them. Sometimes you can determine what brand they are using. They wanted almost twice what I paid for a hydraulic pump on the steering circuits. Same pump they were using. Pt could overnight the part to you.

This thread discusses the PT425 wheel motors in great detail:
web page

( The White part number is 400230W3122AAAAA )

( I bought the replacement from the local White Hydraulics distributor. White's web site lists the distributors. Nationally, Precision Fluid Power sells them over the web, although you need to ask for a quote. They run about $320 plus shipping. )

Note that these are the "high torque" motors, which PT started using in 2003-4, so it might be a different model.

While you are buying a replacement wheel motor, why don't you buy the version with the integrated drum brake (K31 vs W31)? I think that would be money well spent.

Keeping the hydraulic fluid clean is about the only thing you can do, and not reverse the wheels.

Thanks for the information. I got a quote from PT of $486 + shipping for a replacement. I like your price much better!

I decided to get the repair kit from PT and let the local hydraulic shop do the work. Repair kit was about $50 + shipping. I hope labor doesn't put me over the $300 mark.

Well I guess I am in deep pooh! I reversed the wheels when I swapped all the 2 plys for 6 plys. By accident of course, wasn't paying attention and too laz.. I mean tired to swap them back. Mabe when I replace all the wheel motors I can correct this obvious defect.

I am sure that there are others that have had failures on their wheel motors, but were ashamed to admit it. Sure it looks good and should give better stability, but the cost of wheel motor replacement will get their attention at $400 plus. They should not even charge you a half hour on that seal replacement if they are any good at all. Make sure they check out the wheel motor under a load when it is put back together, and give a warranty for their work.

I was considering reversing mine also. I have been waiting to see something like this on here. Sorry it had to be at your expense though /forums/images/graemlins/confused.gif

A little voice kept saying don't do it. Along with a few voice's on this forum. Glad now I listened to it. Once again sorry for your expense and down time. Hope she runs trouble free from here on in.

Thanks for being big enough to admit you reversed the wheels, it may save someone else, (me for one) from going through the same thing.
