I took out the wheel motor fill plug and the oil was under extreme pressure. After releasing the pressure the track worked fine. Now the motor is loosing oil big time around the sprocket where before I released the pressure there was none. It leaks a lot when the machine is running and stops when I shut it off. I suspect the wheel motor has lost it seals. Given the age of the machine what is the best approach? Buy a new wheel motor? Waiting to hear back for price from dealer. Best guesses? Are there used ones around? The dealer did not recommend seal kit as he said usually excess wear has cause the original to fail. The machine runs excellent. Thoughts?? [Reply]   [Send Email]

Once before I drained oil off the motor and I wondered then if something was bypassing. A new one is $7800. Almost as much as the machine is worth. The Parts Connection wanted $4000 for a used one. Getting the motor off and getting a free quote as to costs before I go any farther. What is the best procedure for removal? Lossen track. Remove oil lines. Then remove all bolts on sprocket. Is That it? Thanks for the help. Kevin   [Reply]   [No Email]

Then there are some that will come out but you have to break the track for clearance issues. Lastly there are some that you have to break the track because the motor, sprocket, and final drive housing are all an integral unit that has to come out together. Your best bet would be to call the dealership and ask someone in the shop. Tell them that you called the other day about buying a new one and need to know how the old one comes off. They don't need to know that you might not buy the new one from them and in most cases are more willing to help an individual if they think the dealership will get something out of it.   [Reply]   [No Email]

Your best bet would be to find someone that could do a rebuild for you. A proper rebuild will replace any parts worn out of spec, lap in any metal to metal sealing surfaces as well as replace any "soft" seals. Basically reman is as good as new and can usually be done for alot less than new. This is usually more cost effective. If available the dealership often has remans that they will swap out for your old one, but before going that route check out the link below and make a few calls to the "aftermarket" rebuilders and suppliers. I've found that they are usually alot cheaper than the OEM and the quality is usually just as good since most machine OEM's are using parts like your track motor that are actually made by another OEM so are available independently and often cheaper.

Often hyd. motors will have a 3rd smaller hose to drain off excess oil from internal leaks. If it does, perhaps it got blocked somehow. Dave   [Reply]   [No Email]
