This oil seal goes over the bearing at the end of the mainshaft (left side), it has a hole for the clutch push rod. If yours is leaking or if you're rebuilding the transmission, it's a good idea to replace this seal. This fits many of the Honda CB twins from the 70's. The clutch push rod seal is a common leak on the CB450, if yours is weeping, replace it before it pops out or gets worse.
This is a high quality new seal produced in Taiwan. When it comes to rubber parts and seals it's generally better to install a brand new part instead of using a NOS part which has hardened due to age.
A great way to isolate where an oil leak is coming from is to clean the area thoroughly, put some baby powder on the area you suspect it's coming from, then go for a 5-10 minute ride. Voila, the leaks location is revealed! Clean everything thoroughly and install the new seal with a deep socket with the same outer diameter as the seal or a seal driver. Make sure to push it in evenly. An oil tight engine puts the mind at ease and it keeps the engine lubricated!
*Sometimes a light coating of three-bond or hondabond is necessary to keep the seal from popping back out if you have a recurring problem. We have Hondabond available.
