Hi
i want to change new koyo bearings and oil seal for Differential Output Shaft

can I use old Collapsible Spacer for GKN Differential Output Shaft reassembly ?
or better buy a new one ?

 

New. If all the planets align you may get away with reusing an old one in limited circumstances but hardly worth the hassle.

 

Buy a new one.

 

NEW one, and while your out getting them, buy some more beer.

 

I just finished doing this yesterday. It does take a lot of torque to crush the spacer, make sure the bearing is oiled and can slide on the shaft, plus grease the face of the washer and nut.

My bearing didn't move easily on the shaft so I ended up stripping the threads of the nut Then I reused the old spacer and pressed the bearing on the shaft until it was seated.

 

This is my first post on Jaguar Forums! I've been on jag lovers for years but it's been quiet there lately.

Here's a different take... The spacer is collapsible to take into account variation in output shaft housing machining. Housings are fairly variable, but bearings aren't. They generally are a consistent size. If you measure your old bearings and new bearings and find them to be the same thickness, then you can reuse the crush spacer. If I'm wrong, you will not have wasted much time because You measure the bearings preload by the amount of torque it takes to turn the assembly... if after assembly you find I'm wrong and you don't get the right reading, take it all apart and do it with a new sleeve.

The only reason I'm suggesting this is because the amount of force it takes to crush that sleeve is huge. It took me forever, and I was constantly scared I was going to overdo it.

 

That it does. I had the stub axle in my vice and was turning the nut with a wrench that seemed like it was sized for working on locomotives.

I had to grab it with both hands and brace myself against the bench to get it to turn. Messed up my knee for a week when I got the angle wrong and put too much pressure on my knee. Be careful!
