Title: C15T gearbox oil quantity
Post by: cee-b on 13 Jun, 2021, 18:37
I have just changed the gear oil on my C15T.

I was expecting to put in half a pint, but the oil started running out of the level plug at approx 150mls - roughly quarter of a pint.

This seems like a piddling amount of gear oil (particularly in a bike not exactly renowned for hanging on to every drop of oil that is put into it!)

Any ideas on why it might take so little? The level/drain plug was fitted by the previous owner - does anyone know whether there are plugs that fit, but are set to a different level?

Cheers
Col

Did you empty all the original oil out?

Yes I did.

I was surprised at how little came out and thought it must have been leaking. However, it is likely that it had just been topped up to the level plug not filled with a measured amount

I just drained my B40 yesterday and approx 1/2 pt came out.
