Getting ready to start reassembly of engine - after a burned piston engine failure. Just got the block, crank and head back from the machine shop. Kit includes new head bolts.
I have the manual, thanks to this forum. The torque specs (pages 9 - 11-16) list many torque to yield TTY bolts.
My previous experience tells me replace all TTY bolts, Is this necessary or recommended?
Head Bolts? 44ft-lb + 90deg + 90deg YES I am going to replace.
Injector hold down? YES I am going to replace.
Crankshaft -
Main Bearing Bolts? 40ft-lb + 90deg ? Necessary or Recommended?
Rod Bearing Bolts? 44in-lb + 221in-lb + 90deg? Necessary or Recommended?
Vib Damper Bolt (10.9)? 240ft-lb + 90deg? WOW! Necessary or Recommended?
Flywheel Bolts? 33ft-lb + 90deg? Necessary or Recommended?
Camshaft -
Exh. cam Sprocket bolts? 159in-lb, not TTY, but manual says "Do NOT reuse"? Replace?
Cam tower bolts (24 of them). 80in-lb. Not TTY, reuse?
Any others?
After reading many threads on the vibration damper, should I replace it? Mine is single pulley with no visible problem.
