DF90A Gearbox Drain Hole Thread Size

[Daneyboy]

DF90A Gearbox Drain Hole Thread Size, I think it is 10mm, can anyone please confirm for me. Need to buy a hand pump to change out gear oil but not sure of drain hole thread size.

If you take a look at the service manual on page 0A-13 you will find info and confirm that thread size for draining the gearbox is 10mm (Gearcase bolt).
About hand pump... if you don't have one yet, take a look at Quicksilver hand pump (yellow and white) that is made for quarts. Video how it looks in action.

If you can’t find the correct thread you can get a cone shape top for your oil jug and just squeeze the oil in. Not as neat as the proper setup but it works.
