FILLING THE GEARBOX

The gearbox filler plug is on the side of the gearbox, so it is impossible to get a standard one-litre oil bottle alongside it. I filled a squeezy oil bottle to the brim, and bent its spout intothe filling hole. I was able to squeeze about two-thirds of a litre in, then refilled the bottle agan, and squeezed the second two-thirds in, this bringing the level to the maximum.

A large syringe is another option if you can get one.
