GEAR CASE DISASSEMBLY
IMPORTANT: Counter rotation (CR) gearcases use unique components and require different service procedures. Use care when working on counter rotation gear cases. DO NOT interchange parts between standard and counter rotation models. Identify gear case type before disassembly. Make sure the “CR” marking is on the end of the propeller shaft.

Remove the two retaining screws holding the propeller shaft bearing housing.
- “CR” marking
- Retainer screws
Remove the propeller shaft bearing housing from the gearcase using:
• Propeller Shaft Bearing Housing Puller Kit, P/N 354060.
DO NOT use tools designed to push on the propeller shaft. Pushing against the propeller shaft could damage the forward gear thrust bearing or thrust washer.
Install the threaded adaptor from the puller kit on to the propeller shaft until seated.
Assemble puller kit components. Hold adaptor with wrench and turn nut clockwise to pull bearing housing.
Pull propeller shaft and bearing housing far enough to loosen the PRESSED bearing housing from the gearcase housing.
