Default Villiers F15 head bolt torque

Hello, have taken the head of my F15, and all looks good. Can't find the torque settings for the head though anywhere though. Have searched this forum, internet....blank. I have a workshop manual for the Villiers, including the MK15 but not the F15. I'm guessing that the settings for the MK15 in this manual will be different settings to the F15.

any clues much appreciated.

Mk15 is an OHV 150cc engine, totally different.

The F15 handbook has no torque information, but it does mention that a workshop manual was available.

Hello, many thanks for replying and for the setting. Very much appreciated.
I have the spares and operating handbook for the F15, but couldn't find it in there. Is there another manual that I could obtain?

best wishes and many thanks

They don't need to be that tight! Chance of over stretching the bolt or making it difficult to remove later, stripping the thread or snapping the head off.

I was tempted to do them up grim tight , but they weren't so tight that my daughter couldn't release them.

Any links to a maintenance manual would be very welcome. I already have the operating and spares manual.

many thanks

Don't know about this particular instance but many older engine manuals don't give torque figures - I guess 'back in the day' fitters just knew by feel when it was about right.

I have seen instructions such as "dead tight" for head bolts which I believe means as tight as you can get it by hand with a spanner of normal length for that size bolt - not your biggest T bar plus a bit of scaffold tube and both feet braced against the engine!

The F15 maintenance manual appears on ebay from time to time.

There's a pricey one here:
