I've just rebuilt my oil pump (new shaft, rotors and seals) - now I'm putting it back on, I'm sh*t scared of stripping threads whilst tightening the five retaining screws.
Anyone got a torque that they've used in the past on these babies ? Or is it just a case of doing them up 'good and tight' ?
My mate Paul suggested an impact screwdriver - but he's just bought a knackered BSA Bantam D3 and is therefore not to be listened to.

Here's the torque chart from the Yamaha manual...look for 'pump cover'.

12inch lbs in one foot lb...just in case you were unsure... :)

Never use an impact driver to do up screws!

Hope it helps.

Hi,
and please take normal allen screws instead of the shitty buttersteel phillipshead screws.
Then 10Nm is correct.

That's from the official Yamaha workshop manual.

Best regards

In my book Impact tools are for REMOVAL ONLY.
