IMPORTANT:
Perkins 3681P054 is a timing gear cover gasket for the Perkins 1100 series (1103C/1104C/1104D). Cat equivalent is 226-8766. The Perkins 1100 series timing cover uses multiple gasket pieces in different positions — this is one specific piece. Do NOT assume all 1100 series timing cover gaskets are the same. Cross-reference: if your parts book shows Cat 226-8766, this is the identical gasket.

Perkins 1100 series engines are used in Massey Ferguson tractors, Cat backhoe loaders (as 3054C), JCB equipment, and many other OEM applications. Failure symptoms: oil weeping from the timing cover area. When replacing, inspect the front crankshaft seal and replace if hardened — the labor overlaps. Clean all old gasket material from the cover and block surfaces before installation.

⚠️ Cross-ref: Perkins 3681P054 = Cat 226-8766. Verify specific timing cover gasket position.
