Wheel Motor Leak

Barryh · May 26, 2006

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.

tlb,

Just curious...

How many hours are on your PT?

I'm running reversed wheels AND I've loaded them with windshield washer fluid (and tire sealant). I loaded the tires about 100 hours ago and reversed them about 50 hours ago.

Personally, unless this becomes a chronic, "high failure item" from doing that, I'll trade the increased safety and stability for the increased cost of maintenance. I bought my PT to work on hillsides, because it is one of the best machines to work on hillsides, and these changes increased its capability to do so. I've attached a picture of the kinds of areas I'm using it...

If I can't safely use it on my slopes, then I don't need the PT -- it's really that simple...

So, how does reversing the wheels result in a seal leak? I've seen other numerous seal issues without the wheels being reversed.

Just curious...

Reversing the wheels moves the load out further on the shaft than the motor is designed for. It is agravated when you rollover something on the outer edge of the tire. It puts more stress on the motor with that side load. Will it result in failed seals? Who knows? /forums/images/graemlins/crazy.gif

If we're talking about the reversal to increase width [which I believe is the case here]:

This puts more axial twist agaisnt the shaft; while the deflection should be mininmal, every little bit will contribute to seal failure. However, if the seals fail without accompanied bearing wear, I can't see the reversal being the primary culprit.

More likely I'd imagine contamination or very high cyclic loading (which loader work creates in all directions: both axial directions, as well as pressure cycles; torque too, but this should not affect the seals).

So, I'd say not reversing is a possible preventative measure, but wouldn't worry about it if you prefer them reversed. More inportantly keeping the oil clean, and avoiding ramming the loader or other high impact activties should give maximum seal life.

Sorry, I was watching hard drives format (kind of like watching cement dry) and had a few moments to kill. /forums/images/graemlins/tongue.gif
