Well I put the new crank and bearings in tonight but i realized that the rod bolts are torque to yield as well as the main cap studs and bolts. So now i need more hardware (the local dealership loves me). My question is the torque spec and degree of yield for new OEM hardware. I got the torque sheet off LS1howto i just want to double check it.

All i know is when this is done the sexy black bitch better fly.

 

You're building an engine without a Helms or some other spec sheet?? Wow....how do you know the bearing clearances, crank endplay, rod side clearance, etc are right?

 

my thoughts exactly

 

i have the spec sheet off of ls1 howto but i'm double checking it to know that it's right.

 

TTY specs are:
Main bearing cap bolts(in sequence)-
Inner bolts: Step 1.....15 lbs.ft, Step 2.....Turn an additional 80*
Outer stud nuts: Step 1.....15 lbl.ft, Step 2.....Turn an additional 50*, side bolts.....18 lbs.ft.

Connecting rod caps bolts or nuts: Step 1.....15 lbs.ft., Step 2.....Turn an additional 60*

Windage tray nuts: 18 lbs.ft.

You need a book

 

yeah u'd think i'd have one since i work in an auto parts store. But they get bought up so fast. thanks for the info thats all i needed. When the rest of the bolts get here tues i'm putting this bitch back together
