1983 Honda CB1100F · Gaskets & Oil Seals Buying guide

Sealing a leak or rebuilding

Single gaskets suit a one-cover job, such as the valve cover or clutch cover. If the engine is coming apart, compare the Athena set contents with the separate gaskets and seals you would need.

Reading seal sizes

Seal listings give three figures: inside diameter, outside diameter and thickness. The crankshaft seal is 25 x 42 x 8 and the oil pump shaft seal is 25 x 47 x 10, so similar seals are easy to mix up. Measure the old seal before ordering.

Cover gaskets one at a time

Separate gaskets are listed for the alternator cover, left crankcase cover, clutch cover, oil pan, spark advancer cover and starter motor cover. Each listing gives the OEM number it replaces, which helps when a single cover is weeping.

Gasket and seal questions

How many camshaft holder seals does the engine need?

The listing says one camshaft holder seal is required per engine. It is a triangular rubber piece with rounded corners, sold each, and replaces OEM 91311-425-000.

Does the Athena set include valve stem seals?

Yes. Its contents list 16 valve stem seals, four exhaust headpipe gaskets and the camshaft holder rubber seal, along with the main engine and cover gaskets.

Is the engine cover bolt set a stock part?

No. It is a stainless steel set of 38 smooth-head Allen bolts with two Allen keys, sold as a cosmetic replacement for the visible engine cover fasteners on the CB1100F.
