Turning Crankshaft by Hand

Hi, we have recently replaced the head on our Westerbeke 40 (Perkins 4.108) and are now trying to set the tappets we need to turn the Crankshaft by hand. Is there a special tool we need? our crank pully has an opening for a socket of 1 and 1/8". Do mechanics have a special tool or is there another way we haven't thought of.

Thanks

Re: Turning crankshaft by hand

Usually a breaker bar and socket with an extension will do it.

A socket on the balancer bolt will work just fine. Be sure the fuel is off and the battery is disconnected.

I turn my 4.108 over with a large adjustable spanner.

Re: Turning crankshaft by hand

Am I right in assuming that you don't have a 1&1/8" socket and are looking for another solution?
