I've searched and cannot find it, so.

What is the head bolt tension for the standard G150 in the Belletts?

Cheers Rob

Hi Rob
I think I recall standard is 7kgm = 50 ft lbs
I go higher to about 9-10kgm = 68-72 ft lbs
Depends on 'feel', Belletts have heapem big head bolts.
Best to
- clean out the thread with a tap
- use Assembly lube on the thread and under the head
Bolt (at a push could use engine oil but not quite as good)
Cheers
J

I'm going back a long time, but the G150 has two head bolt sizes if I recall, 17mm for the 3 Bearing and 19mm for the 5 bearing, so I would assume two different settings, be careful about overtightening.

Tis good 67GT :D

Wish it was easier to clean the head and block of the accumulated gunk.

40+ degrees then constant rain ... blah. Hard to get anything done at all.
Head is nice and clean now.
Next is to clean bolts and rocker gear, then if I can get some fine weather, the block.

Cheers everyone :D
