Posted: 22:00 - 17 Apr 2017 Post subject: Generator head bolt torque |
|
|
Hi, apologies it's not a bike engine but the generator does power my bike's tyre warmers. I have a Powercraft 3200 generator that looks to have a head gasket that's on the way out. I can get replacement parts for it fine but I can't find a repair manual for it anywhere.
Because of this I have no idea what torque the head bolts should be. Has anyone here rebuilt a generator engine before that would have a rough idea what they might be? I won't know what thread size they are until I pull it apart. I was going to try tightening them with a torque wrench set to increasing increments to try and guess the torque, but if they're stuck fast (it's about 5 years old) that won't be any use.
Cheers |

Simply torquing the bolts isn't a great idea. If the gasket is on it's way then it's probably that the head or barrel has a warped surface. ____________________ a.k.a 'Geri'

I have never, never never not ever not even on my home-built 400hp turbo bike gone back later to re-torque the head bolts, and I've never suffered from not doing it. ____________________ a.k.a 'Geri'

Hi everyone, thanks for the info. Tried contacting Aldi but they want receipt numbers which I don't have - bought it 5 years ago.
I've got hold of a gasket set for £18 so whipped the head off. Bolt looks to be steel, either zinc plated or stainless, I can't tell.
Bolt dimensions are: M8, 1.25 pitch, 55mm long. Head looks to be cast aluminium. Bolts have 'KY' on the top of them

Good shout on the GX engine, I'll have a look. Old head gasket looks OK to me but it is definitely leaking air from the top part, once the engines up to temp you get one side blowing cold air through the gasket and the other hot.

If it is a warped head then I'll not be too upset spending £18.
Thanks |
