This afternoon, after a diff seal-free w.e. I finally succeed in removing this one. This seal was made of 3 circular crowns (1,2 and 3 in the picture I have just posted) with the 2nd and 3rd crown free to move. A very big and complex seal, nothing to compare with the new simple seal I'm going to fit in my diff. A last thing: I have not seen the washer 539745 that from Les' picture appears very thin. The only think I see now is a cylinder that protudes for less tha 1" from the bearing surface and that wraps around the pinion. The flange is stopped by this part or not? And, 'cause I've bought the washer 539745 too, I had to fit it or not and after, provided that I have no play in the bearings and that my diff is a rover one, can you suggest me the maximum load I can tighten the pinion?
Bye!
