O.S. Engine OS29707000 Cover Plate for GT55 Crankcase  [OS29707000]

Overview of the GT55 Cover Plate

The O.S. Engine OS29707000 cover plate is supplied to restore the crankcase sealing surface on GT55-series engines and to protect internals where the original cover is worn or damaged.

Fitting requires clean mating surfaces and correct alignment of dowel pins and bolt holes. Use the original screws where possible or equivalent replacements, use thread-lock as needed and tighten to the specified torque to avoid deforming the plate or crankcase.

This item preserves crankcase integrity and is not a power-modifying component; a correct fit contributes to steady compression and prevents oil or fuel seepage that could affect ignition and carburetion setups. Replace any spent seals or gaskets during the service.

Designed as a replacement for GT55 crankcases using the OS29707000 part number; verify part references against your engine parts list prior to ordering to ensure correct fit.
