[vvulture]

Hey guys,

In the process of rebuilding this 1968 40hp motor.

Can anyone help me with information regarding torque settings for the various components ? Especially the head bolts, flywheel, con rods, crankcase etc etc...

Thanks guys,
Your help will be greatly appreciated...

Thank you bobbyc... much appreciated.

However, is there any chance you could repost a somewhat larger image ? It is very small and im having a hard time reading the numbers.

Also, will these be ok for the 68 model ? I can see that the engines are almost identical...

Thank you
