when you say face seal , I think you are talking about the white concaved ring that sits behind the output shaft , I have reused them without a problem -------------- but if I had it apart I would change it , I hate to have to do things twice
Face seals are 2 precisely machined metal rings with rubber o-rings backing them. The machined pieces are so precise that when they are put together face to face they can spin on each other without leaking oil. They are the seal that allows the sprocket to spin while the motor is stationary without leaking the carrier oil. Face seals are also used in the under carriage rollers and idlers. If you have an external leak of gear oil on your drive motors the face seals are more than likely bad (thats if you notice the leak). The face seals in the drive motor are very expensive ($200+ last time I bought them) and thats why I want to reuse them. I looked at the parts break down of the drive motor and it looks like I might not even have to mess with the face seals. Now I just need to get the motor apart. The 8 bolts that hold the motor together are rusted in there pretty good. Salt does wonders to metal
Now I got you with the face seals , there was no discription of machine in your post , I picked up the words travel motor and was thinking wheeled machine , see now it is listed under tracked loader ------------ I will change the bearing housing assembly or a brake pack OEM from Bobcat but gave up on rebuilding , I am not working on my own equipment and have to warranty the work and have found that going back into them can become pretty regular even using the OEM parts , "NONE" of the local hydraulic shops in New Orleans area will even touch a Bobcat tracked loader travel motor assembly , I gave a small local hydraulic shop 14 partiall\cores that I had robbed brakes and or housings that were still good off of and he said it was going to give it a try , it's been over a year and he still ain't got one out yet , I should have taken them to the scrape yard and got a couple of cases of beer with the money -----sometimes the dealer gets factory remaned units for $2,800 , a complete assembly is going for $4,300 , the housing assembly is at $1,200 ------------ those bolts do get hard to get out , I find a cut off of an allen wrench and a combination wrench with a hammer works well , luckily when you buy a new housing they give you new bolts ----------Face seals are 2 precisely machined metal rings with rubber o-rings backing them.
