Repair Parts for 2pc. Timing Covers

The Cloyes Repair Parts Kit for 2-piece Timing Covers (MPN 9-221D) is a precision hardware assortment designed for technicians and engine builders maintaining or replacing Cloyes Quick Button timing covers. This kit supplies the critical fastening components—bolts, lock screws, and O-ring seals—needed to reassemble two-piece timing cover systems with proper clamp load and seal integrity. Timing cover hardware kits like this eliminate the frustration of sourcing individual fasteners and ensure you have OEM-spec components that mate correctly with Cloyes quick-button mechanisms.

The kit's lightweight footprint (0.15 lbs) and compact dimensions reflect efficient packaging of a focused component set. O-ring seals are critical in timing cover assemblies because they prevent oil weeping at the cover-to-block interface—a common failure point when original seals degrade or incorrect fasteners allow covers to shift under engine vibration. Using the correct lock screw and bolt specifications maintains consistent clamp pressure across the cover face, which is essential for preventing oil leaks on higher-RPM engines or those with elevated idle pressures. The Cloyes brand is recognized in the engine builder community for precision timing components, making OEM repair kits a straightforward choice for warranty-conscious rebuilds.

This repair kit suits engine machine shops, performance rebuilders, and serious DIY restorers performing timing cover maintenance or replacement on vehicles equipped with Cloyes two-piece covers. Whether you're refreshing a vintage engine block or addressing a slow oil seep during a larger rebuild, having dedicated OEM fastening hardware on hand prevents downtime waiting for special orders. Technicians value hardware kits because they provide confidence that every component in the assembly matches the original engineering specification, reducing comebacks and ensuring long-term seal performance.
