Seal, stopper ring, or top cap

Match the seal to 35 x 48 x 10.5 / 11mm. The stopper is the metal ring above that seal, a pair that names this twin. The cap is the 35mm tube bolt, usually two per bike, with an O-ring.

Seal, ring, and cover rubber

The seal set is 35 x 48 x 10.5 / 11mm, and the title names CB500 with CB750, CB650, and CB550. Stopper 51447-KL4-951 is the metal ring above the seal, a pair that names the 1975-76 CB500T. Cover rubbers are a separate pair under 51601-300-000. Do not put a cover rubber in the seal bore.

Cap bolt and the 35mm wrench

The cap replaces 90123-300-000, includes its own O-ring, and uses an M28 x 1.5 thread on a 35mm tube. It is sold each, and two per bike is the usual count. A fork cap wrench is named at 35mm for these caps. No other wrench dimension is given, so match that 35mm size only.

Seal, ring, or cap bolt?

Does the stopper ring replace the seal?

No. The ring sits above the fork seal, a pack of two, replacing 51447-KL4-951, and it names the 1975-76 CB500T. The seal is the 35 x 48 x 10.5 / 11mm set. Order both only if both pieces are worn.

How many cap bolts do I need?

The bolt is sold each, and the description says usually two per motorcycle. Each one includes an O-ring and uses an M28 x 1.5 thread. The fitment includes the 1975-76 CB500T plus CB750, CB550, and CB450K 1970-71.

Are the cover rubbers the fork seals?

No. Cover rubbers are a set of two replacing 51601-300-000. They name the 1975-76 CB500T, CB750K through 1976, and CB450 and CL450 models. They are not sized 35 x 48mm. Use them on the fork covers.
