Message: <blockquote data-quote="clr1001" data-source="post: 13886" data-attributes="member: 1570"><p>I spoke with Perry on the phone earlier today, and he suggested I ask the forum: I recently (yesterday) purchased a Bobcat 853. The engine and hydraulics work great, BUT it has a (or several, in my opinion) big problem which occurred before I bought it: The left rear axle seal went out. Then the bearing(s) went out. I believe all the fluid is gone. The seal and bearing are completely chewed up. The driveshaft has been running on the upper edge of the axle, causing the axle to bulge. The driveshaft is pretty chewed up out next to the wheel hub. To further aggravate this situation, the lip that runs around the wheel hub that holds the studs on (that holds the wheel on) is COMPLETELY worn down--I'd guess about an inch of meat that encircled the axle is gone from the hub, and I didn't measure how much axle meat is gone. Other than that, I think the machine is in great shape. It's got 3655 hours on it. I was thinking about taking it apart and rebuilding it. Here are my questions: Should I just scrap or trade the thing, or should I rebuild it? If I trade/scrap it, then it's somebody else's problem, but if I choose to rebuild it, I'm gonna need some manuals. Are there any parts diagrams available on the internet for my 853? Also, do I have to take the machine apart from the top? It looks like the belly pans don't come off, so that's what I am thinking has to be done in order to get at the drivetrain. I don't have any manuals yet, but I have to figure out how to detach the drive axle from the inside. If I rebuild it, I was thinking about putting in a new axle shaft, bearings and seals. For the axle itself, I was thinking about cutting the old axle back to where it is solid, welding a new piece of pipe (axle) in with flush edges, and then welding another solid sleeve over the top of the entire piece of axle that sticks out from the side of the frame, and then butt-welding that sleeve to the frame of the machine. That's the only thing I could think out to make sure the strength is there so my welds don't break with all the wear-and-tear on the axle. Any thots? Thanks.</p></blockquote><p></p>
