The instructions from my set are in my box at work...I can get them tomorrow and post them up for you in the morning? IIRC there were two different settings, one for use with their own molyslip grease and another torque setting for with out said grease.

cossiemanden

If you use arp grease, then 40nm first time 80nm second time and 110nm third time then recheck if every nut have 110nm, then heat car up to normal driving temp, leave it for a day, then loosen nut half a turn, and tighten 110nm, but only one nut @ a time.
Have worked on thoose 5 engines i have made

BigErn

JTECHSAFF maybe thats what caused the crack then

BigErn

Place your guesses how this happened.

JTECH James

being no 4, it may have had oil pressure issues causing the bearing failure...no4 would be the first to loose its oil...

any signs of heat on the remains?

jacko

ooooooh yesssss
the bearings turned to water and disintegrated lol
