1975 Honda CB500T Oil Seals and Overhaul Gaskets

Oil sealing and head sealing are different purchases on a 1975 CB500T. The rubber seal kit is not the head gasket, and neither is the overhaul gasket set. The set names this model, then says it fits 5-speed CB450K models only.

1975 Honda CB500T · Gaskets, Oil Seals & Engine Hardware Buying guide

Read the overhaul note against the fitment line

You can buy seven oil seals, one head gasket, or an overhaul set. The overhaul set names the 1975-76 CB500T and also says 5-speed CB450K only. Those two claims disagree, so do not treat the set as every gasket this twin needs.

Parts to consider

1968-76 Honda CB450 / CL450 / CB500T Engine Oil Seal Kit Engine oil seal kitSeven oil seals for Honda twins, for 1968-76 CB450, CL450, and CB500T use. The individual Honda seal numbers are not printed. Use the kit when the rubber seals are hard, leaking, or no longer holding oil.View part Honda CB Cylinder Head Gasket ~ Replaces 12909-428-003 Cylinder head gasketThis is one head gasket replacing 12909-428-003, 12909-283-000, and 12909-333-000. It is written for a twin or a four-cylinder Honda, and the 1975-76 CB500T is among the models named. Buy it when the head joint is the part you are sealing.View part Honda CB Overhaul Gasket Set Engine overhaul gasket setThe overhaul set names the 1975-76 CB500T, CB450K 1965-74, and CL450K 1968-74, and the same write-up says 5-speed CB450K only. Contents are not itemized. If you need a known head gasket, buy the separate gasket by its Honda numbers.View part

Do not guess what is in the set

The overhaul set does not name the gaskets inside it. Do not assume a head gasket or an oil seal is packed in it. The head gasket you can match by Honda number is the separate gasket.

Head-gasket years versus the overhaul years

The separate head gasket is not held to the 5-speed CB450K note. Its printed years are CB500T 1975-76 Twin, CB400F 1975-77, CB350F 1972 and 1974, CB450K 1966 and 1968-74, CL450K 1967 and 1969-74, and CB360T 1975-76, then a CB360 line with no year. Those spans differ from the overhaul set.

Overhaul set and seal-kit questions

Does the overhaul set fit a 1975 CB500T?

Fitment includes Honda CB500T 1975-76, and a note says it fits 5-speed CB450K models only. Nothing says which sentence controls, and nothing states the gearbox in this model. Compare both lines to the engine you have instead of dropping one.

Is the head gasket inside the seven-seal kit?

No. The kit is seven oil seals for twin-cylinder engine assemblies. It does not describe a head gasket, and it does not mention 12909-428-003. That gasket is a separate piece. The overhaul product is the gasket set, and its contents are not itemized either.

Why does one head gasket show three Honda numbers?

12909-428-003, 12909-283-000, and 12909-333-000 are the OEM identities this one gasket replaces. They are not three gaskets in the package. Match any of them to the gasket you are removing. The 1975-76 CB500T is one of the models named for that same gasket.
