Hi there,

Small bit of oil leaking from the gear selector shaft on my NC39 Super Four, just wondering how do I change this?

Thanks in advance.

Hi Bear, not sure if you have got your problem sorted now? my cb400 superfour had the same problem, which i intended tackling prior to discovering my electrical woes.

As far as i can gather from what the guy in the Honda dealers told me after he had looked it up, the oil seal for the gear shaft fits a few Honda models, it cost me 3 quid and this genuine honda part says on the packet for CB400/CB500 and CB1100 part number 91203- KA4-771. ianyway im sure the Honda dealer will be able to asisst if this is not for your bike.

I have still yet to fit it, but they should just pop out ,carefully using a screwdriver or oil seal puller tool.
The new one , grease it and push it in using a similar diameter socket if possible.

When you do come to fit the seal tape up the splines on the shaft otherwise they just might cut the lip.

Cool. Thanks for the replies lads.
