wot torque setting should the head bolts be??
also can i re use the head bolts they are high tenisal mild steel?

cheers
neal

 

i know u cant re-use CVH headbolts as they stretch so i wldnt tbh.

torque settings for CVH are:

Stage1 25nm 18lb/ft
stage2 55nm 40lb/ft
stage3 tighten by a further 90degrees
stage4 tighten by another 90 degrees

(by stages it means do the head bolts in the correct order, then 2nd time, 3rd time, 4th time )

 

they are different 2 zvh. how can u tell if they are stretched

 

they are different 2 zvh. how can u tell if they are stretched

 

they'll be stretched if theyve been used.

 

help again!! i was told that i should do them to 75lb/ft is this rite?? also is it in nm?

thanx

 

Yes if you use a std 10.9/12.9 caphead bolt m10 x 150mm long the max toque setting for these is 75lb/ft as these bolts do not stretch as they are not designed too hence the lower torque setting to the std cvh bolts that have to be toqued to yeild or laymans terms (stretch bolts)
and because they are not yeild bolts they can be re-used again and again the setting i use are:

40lb/ft stg1
65lb/ft stg2
75lb/ft stg3

run till warm then recheck 75/lb/ft

hope this is of sum help??
