Re: Retorquing After Rebuild - Volvo Penta MD2040

I just Googled "torquing a perkins cyl head"
Here is a video :

There will be others on Youtube for different engines. The principles are the same regardless of brand.

I agree you would very likely be safe to go another 50-100 hrs to get somewhere with a mechanic & a torque wrench.

Re: Retorquing After Rebuild - Volvo Penta MD2040

All due respect to Tinkerman.
In the Video the commentator advises to torque head " Hot", it is interesting I was always taught to do it cold. Reasons being that when they are done cold you obtain the extra 'Squeeze" from the expansion of the head with heat. You could argue the bolts will expand ie lengthen when they get hot, maybe 6 of one and half dozen the other!!

I just did a quick Google for OP's benefit & didn't pay enough attention I guess.
I'd rather do it cold-makes more sense to me,but.......

Technically,you're supposed to only use head bolts once also-from my younger d-racing days,but....

Also,IIRC,you use only motor oil on the threads,but....

6 of one & half dozen the other - sounds good to me

Learn to torque in the first place or learn to take extra head gaskets and then learn to torque anyway. One bolt is all it takes.

Re: Retorquing After Rebuild - Volvo Penta MD2040

If you have a recent rebuild I would be thinking about changing the lube oil and filter around now, and adjusting the tappets.

If you have a good local VP dealer, why not book a service and have the whole job done ?
