Hey guys,

 

Was looking for some HG torque specs a while ago and i bought another HG yesterday so i though id post up the torque specs.

 

Specs are for an ACL Ezy Fit head gasket PN BD950EZ. Specs were also the same for my ACL Mono Torque head gasket PN BD950MT

 

Torque ALL bolts to 25Nm or 18.5Ft-Lb. Torque them ALL again to 50Nm or 37Ft-Lb. Then one last time to 65Nm or 48 Ft-Lb

 

Ft-Lb = Foot pounds

Nm = Newton meters

 

Remember to do them all before torqueing them up more. in stages :P

 

Torqueing sequence:

 

8 6 1 3 9

10 4 2 5 7

 

Take it for a drive around the block a few times to get it warm then torque all the bolts up to 65Nm or 48Ft-Lb again as the heat expansion will cause the bolts to loose their torque slightly. I usualy add another 5Nm when i do this.

 

Hope this helps a few of you.

 

CHEERS

Go put it in the FAQ/Knowledge base as all it says is "as per manufacturers specs".

Maybe put a *note* saying to still check the above anyway.

don't all k series run torque to yeild bolts tho?

Nah Todd only 5k's have the shitty TTY bolts. 3k/4k ones are much better and re-usable.

....still no comparison to a an ARP though! :)

The late dished 4k's also have the TTY bolts.
