Rear engine case

[gordonv]

Hi guys,

I removed the rear engine case the other day. This from the engine I took back in trade from my parted out IS, a 27K miles Tourer, which had greanaded/seized. Looks like it might have been 1 or 2 rear rodes.

Besides a few small flakes of metal on the bottom, there was this I found in the seat of the output shaft, where the bearing sits.









The metal wasn't exactly where it's pictured, but it was in the area. The output shaft spun freely, no signs of binding or rough.

The area the bearing goes in looks clean. Would this part still be usable? I'll need to look over the output shaft again to see what goes into that area that was machined out where the metal has been gouged out.

Did you find out the cause of the engine failure? Curious, since these engines often go 300k and more.

Not yet. I shipped the motor up to Kelowna where a Valkyrie owner, who is also an engineer, will look at taking it apart this fall/winter. He has a "project" he said he could us the motor for.

I'll ask him for some photos of what happened inside the case, and try to find this post again and post them here. He also thinks he can weld the ruptured case back up. I figure it's not worth it, no one wants a case any ways.

If the other end of the shaft that rad in that bushing is the output splines to the U-joint a failing U-joint could be part of the cause for the failure shown.

The bore for the bearing race doesn't look to be damaged.

The bearing cage is what probably caused the damage or at least it looks that way.

With this that is pictured, doesn't necessarily make the case unusable.
