Anyone know what the standard cossie rod bolt torque setting is, as i dont have a databook anywhere handy.

Also, whats the standard journal size on the big ends and mains.

(just pulling apart the supposedly "rebuilt" engine ive just aquired to check it over)

So far its looking a little like it was stevie wonder's practice engine if its really not been run since it was built like i was told

Oh, and also ARP head stud torque values on the YB


CheeRS

 

so it hasnt been rebuilt then? or just badly done

 

Chip, have a butchers in the Technical Essey forum.

All the cossie workshop manuals are in there

 

Rod bolts....

Stg 1 28nm
Stg 2 55-60nm

 

Its been rebuilt, but not as recently as i was led to believe, and im a little nervous about a couple of things, but will need to investigate further first.

TBH though, at what it owes me, i cant really complain too much, especially as rather randomly it happens to have a steel flywheel thats never been used and a brank new borg and beck clutch (clutch isnt any use to me, but is certainly saleable)


Steve_B, thanks

GurnE, i couldnt find any torque values in there :S and also i doubt it would cover ARP bolts as they arent standard.

 

I have used the same torque specifications as standard, on both the top and bottom, NEVER had any failures.

 

standard journal sizes:

main bearings - 56.975-56.959
big ends - 51.993-51.977

hope this helps! have got the values for ground cranks if you want them?
i didnt know arp rod bolts had 2 be torqued differently?
