David Brown 990 Rear Axle Removal

getntoed · Sep 5, 2009

We have a DB 990 with the left side brake hung-up (binding causing a lot of drag). I have not been able to get is to release. I am looking for information about how to remove the rear axle. I have the wheel off and all the bolts out. I als have the diff. lock wired up as described in the manual. Does the axle just slide out (using an engine hoist for to hold up on it). Does it take a little effort to get it pulled out away from the tractor or is somthing holding it back?

it can take a little effort to move final drives but it should'nt take much to break contact between the faces,i would suspect the brakes are still binding,you will still need to loosen the brake adjustment rod and tap back the arm at the end of the rod under the axle.tom

Thank you for the help.......it did take a little persuasion but it came out just fine once I gave the brake lever a couple of knocks with the persuader.

I found that the problem was the brake cam shaft was not well lubricated (dry) where it passes through the bushing. The seal was gone and looked as if it had been gone since it was built. Now I cannot remove the brake cam but I am letting it soak with some penetrating oil overnight. The taper bolt wasn't the easiest to get out of the brake arm either. I guess that it just takes a lot of patience and a few skinned knuckles. Have a great day!
