Default 432 Commercial

Hello all, I have a few Gravely related questions. I have an early 432 commercial. It has the rear mounted attachment lift. I found the schematic here :

http://www.oldgravelys.net/pdf/Rear_...t_IPL_1071.pdf..

I have the hitch and almost everything to make it complete, however I am missing part #'s 14721P1 which is the clevis rod, 14719, which is the clevis. Anybody out there able to help me locate these parts?


Also looking for the attachment to hook up the rotary plow and the roto tiller to the front of this machine as well. I just picked up L today with the brush mower, the rotary plow and the rototiller and would like to mount them to the front of my 432 if possible.

The parts that you are looking for do show up on E-bay that might be the place to look or at the Mow-in

I have another question about this tractor. When I got it the PO advised me that it would work in low range and reverse but not in high range or when the mower was engaged it would slow down. I pulled the engine off today and this is what I found. I believe this is the rear ring gear? any ideas what would cause this wear?

Very worn bushings in the planetary gears. Here's what I found in my Pro Master 50 that did the same thing except it would not work in low range.

The bushing is .036 clearance. It should not be more than .002 if my memory serves me.

Well that would explain things, Are there bushing kits available to rebuild the planetary or do I need to send the planetary to Richards?

You can buy bushings for replacement, but you need to measuse the pins and bolts to make sure they are still round and not oval. Those bolts are left hand thread by the way.

Here's some pictures of a worn bolt and bushing next to a NOS bolt and bushing. You can see the difference. What you can't see is that the bolt is .010 out of round.

If it were mine I would replace the orbit gears as well as the ring gear. I would also examine the sun gear (engine gear) for wear. There is also the pilot bushing to examine as well.
