Crankcase Cover Overview

The O.S. Engine OS29067010 cover plate is supplied as a replacement for crankcases identified with the 91SZ-H cover code. It focuses on restoring proper enclosure alignment where the original has been removed or degraded.

Installation follows common RC engine servicing practice: remove the old cover, clean the mating faces, align the replacement plate and torque fasteners evenly to sustain crankcase alignment. It is well suited to tasks such as seal renewal and piston or bearing reassembly.

By maintaining consistent crankcase geometry this plate supports predictable compression during bench tuning. Consider it a routine service spare rather than an upgrade to engine specifications.

How can I confirm this is compatible with my engine model?

Check your engine documentation or the casting/cover markings to confirm the 91SZ-H pattern before ordering; cross reference with your service manual for certainty.

Will replacing the plate affect tuning adjustments?

Replacing a worn plate restores original crankcase dimensions and helps keep tuning consistent, but the plate alone does not increase power or change core engine settings.

Should I use sealant when refitting the cover plate?

Sealant is usually unnecessary if mating faces are clean and fasteners are torqued correctly; only use gasket material or sealant if the engine service instructions specify it.
