I bought some second hand crower rods and bolts so they came with no manufacturers specs, does anyone know what the torque setting should be? Also is it wise to use any lube on the bolts when assembling. Also does anyone thread lock theres?

 

buy arp bolts and use the stretch method use the lube that comes with the bolts or moly lube i am guessing.

 

Will the crower bolts i have not be ok? they are probabley just as good as ARP

 

i would give crower a call and get the correct specs fo the given bolts and there required torque and stretch readings

 

Ha haa i think i will email them as im in the uk and the cost of a phone call to the US will be more than new bolts! good idea i will look them up now.

 

The first anyone would need to know in order to help you is the diameter of the bolt.

 

they are around 8mm or 5/16"

 

Bump as no reply from crower.

 

which rod is it again ill give them a call for you and get the information

 

tired calling i know why you didnt get a response is because they are closed for the holidays open up back on jan 3

 

Oh right i will wait for there reply then. Thanks for going to the trouble to ring them for me.

 

bump, anyone?

 

Crower finally got back to me. They said 25ft lbs using engine oil as lube. Does this sound about right?

One can use any type of lube when using the stretch gauge method.
When using a torque wrench one must use the supplied lube which comes with the bolts.

 

Ive done a search on the stretch method and it does look to be a lot better. I think i might get a set of new bolts. Just for reference Crower said 25 ftlbs using 10/40 engine oil as lube.
