F120AC rear cover replacement component

This back plate assembly serves as a replacement for damaged or worn rear crankcase covers on F120AC engines and is identified by the YS Engine part number YSF1326A. It restores the external housing sealing surfaces and attachment points while leaving engine geometry unchanged.

The item is marketed for its compatibility and service role rather than upgrades. Install this assembly if you detect oil weepage, stripped mounting threads, or deformed surfaces. During replacement, inspect the mating faces, fastener threads, and gasket seating to ensure a correct fit.

Installation guidance: remove the engine from its mount as required, match original fastener sizes, clean mating faces thoroughly before refitment, and follow standard safety steps for RC engine disassembly. This sale is for the back plate assembly only and does not include internal engine parts or consumable seals by default.

Specifications

  • Material: Not specified
  • Model Number: YSF1326A
  • Compatibility: F120AC engines

When repairing an F120AC RC engine, fit the YSF1326A back plate assembly and confirm thread and sealing surface condition to secure reliable operation.

Will this fit my F120AC without modification?

The component is produced as the YSF1326A back plate for the F120AC series and should fit standard units. Confirm hole positions and port alignment before final tightening.

Does the package include mounting hardware?

The description covers the back plate assembly only; mounting screws or seals may not be supplied. Check the seller listing for included items or reuse the original hardware if serviceable.

What prep should I do before installing?

Remove any residue from mating surfaces, inspect and chase threads if needed, replace gaskets, and ensure all ports line up to avoid leaks after assembly.

Could this affect engine balance or internals?

Fitting the correct back plate returns the external housing form and should not change internal timing or moving part relationships when installed per original specifications.
