Item  Qty  Part  Specification Description 
Do not use a torch in order to heat the ring gear. 
Maximum permissible temperature of the ring gear for installation onto the flywheel is 320 °C (608 °F).
12  1N-3825 Bolt  Before assembly, lubricate the threads with clean engine oil, molybdenum disulfide, or a graphite base lubricant. 
Use the following procedure to tighten the bolts:
Tighten the bolts to 100 ± 5 N·m (75 ± 4 lb ft) in numerical sequence as shown in Illustration 2.
Again, tighten the bolts to an additional turn of 180 ± 5 degrees.
Replace all the bolts at the time of service.
