Wheel Horse 520H Axle seals

Recommended Posts

acc7484

Hello All,

 My recent purchase of a 520H has been nothing but one issue after the other. 

The PO claimed he replaced the Axle seals. So I removed the hubs to inspect. The  thrust washers were very worn the seal did not look much better. 

I replaced the seals with SKF 11124. They were not correct for this application, oil was bleeding all over. 

 After a little research I found the correct seals and thrust washers. 

So one side is fine the other is still leaking. Did I miss something? I taped up the axles so as not to cut the seal when sliding them on.

The correct seals are 1/2 inch wide. with a duel lip. 

Is there a special procedure for this?

Thank you for all you help and advise.

How is the axle bearing on the side that is leaking?? If the axle has excess up/down, side to side movement this would indicate that the bearing is bad. This excess movement will damage the seal in short order.

If the bearing is good, make sure the axle is smooth in the seal area. 

I had an issues with repop seal manufactures. You are better off getting those seals away from EBAy repops. 

I use https://wheelhorsepartsandmore.com/shop-now/ good quality there as well as a few others.

Also, you can tap the seal in a little deeper and that will cause it to run on a different area of the shaft.

Always use the tape. I don't spiral wrap the shaft, I put a long piece over the key area, letting it hang over the end of the axle.

Apply oil to the seal and axle before sliding it on.

Himmmmm,

Sorry I missed this first time around, I usually suggest turning the hub around and using that as a ' slide hammer ' to tap the seal into place.  But you got it so all is well.
