PCM Starter Housing Spacer Kit | 97452
Get the starter-to-flywheel engagement right the first time. This OEM-specification starter housing spacer kit provides the precision shims needed to correctly position the starter motor housing on PCM inboard engines, ensuring the starter drive gear meshes properly with the flywheel ring gear.
Incorrect starter housing spacing is a common cause of hard engagement, grinding on startup, and premature ring gear wear. Too little clearance and the drive gear drags on the ring gear; too much and it fails to engage cleanly. This kit gives you the correct spacers to dial in the fit to specification during starter installation or replacement.
Best Use Case
Best suited for use during starter motor installation or replacement on PCM inboard engines where the housing-to-flywheel clearance needs to be set or corrected. Also the right kit when a starter is grinding or engaging harshly and inspection reveals the housing position is the cause rather than the starter motor itself. Commonly needed after engine rebuilds, bellhousing replacements, or any service that disturbs the starter mounting position.

Parts Desk Insights
Spacer selection should always be based on measured clearance between the starter drive gear and flywheel ring gear — refer to your engine’s service manual for the specified clearance range before selecting shim thickness. This kit is specific to PCM engine configurations; confirm fitment using your engine model and serial number before ordering. If you’re replacing the starter motor itself rather than just correcting the housing position, bring the engine model and serial number to the parts desk to identify the correct starter for your application.
