This is an aftermarket part, not a genuine part — the model numbers are used only to identify the saws it fits.
Rebuilding a crankcase means setting the bearings and seals correctly or the engine will not hold crankcase pressure and will fail quickly. This is a job for someone with the right tools and experience.
