580b brake seal leak

[ronztractor]

need some help with my 580 I'm resealing a rt side seal leak that saturated the brake linings.
I found some posts on how to replace the larger seal but I need to replace the smaller seals (2) around the differential lock shaft. can I remove the whole assembly? doing it in the vehicle seems very difficult any help would be appreciated.
Thanks.

I drilled a 1/16" hole in the seal, turned a sheet metal screw into the hole, and pulled the seal out.

ok thanks just seems so tight to get anything in there.

The small diff lock seal can be removed easily by using a modified Oring pick to slide under the seal edge, turn 1/4 turn to stand the edge up and using a pair of side cutters grab the pick and use the end of the shaft to pry against to pop it outta there, before removing it you should use something to measure the depth to reinstall the seal, I have used a piece of exhaust tubing with a stainless steel hose clamp as a stop to seat the seal in a pinch although our shop had the proper driver.

thanks so much that was very helpful, it looked like in the picture there are two seals that go in there is that correct?

mEI Was right on I was able to modify a pick and fish them out, there ended up being (4) seals stuffed in there so thanks so much for the help. the reason I did the seals was because of the oil leakage on the brake linings. I replaced all the friction material and adjusted all the linkage to the factory Manuel but still have very poor brakes. they stop on a flat surface but on any sort of hill they will not stop the tractor I would think I should be able to lock them up. Any suggestions ?

The original diff lock shaft seal was a flat seal that the seal lip flush with the metal shell, the updated seal had a spring loaded lip that stuck out past the shell and if two were installed the sealing lip on the outer seal would be ruined by pushing against the inner seal shell, one will be sufficient.
