I have a 1985 Johnson 2.6L that I am replacing the stock gearcase with a Bobs Performance Nose Cone. Ithe has the integrated LWPU. I got this unit for $150 but it was in need of some refirbishing. I called Bobs and asked about the internals. They said that the stock internals would work because it is a stock unit with the LWPU.

My dilemma:

1. I don't have a OMC shim guage so I don't know if the spacing between the shims and the gear is correct. Any way I can measure it with a tape measure or a feeler guage?

2. I don't have the special tool to remove the driveshaft bearing that's inside the gearcase. Any way to remove it and replace it without that tool?

I have the OMC repair manual for this motor but it doesn't give the specific measurements for the shim spacing.

Any and all help is appreciated
