1. Always use the torque values
above when specific specifications are not available
listed
Note: Do not use above values in place of those specified in the engine groups of this manual, special attention should be
observed In case of SAE Grade 6, 7 and 8 capscrews
2
The above is based on use of clean and dry threads
3
Reduce torque by 10% when engine oil is used as a Iubrlcant.
4
Reduce torque by 20% if new plated capscrews are used
Caution: Capscraws threaded into aluminum may require reductions In torque of 30% or more, unless inserts are used.
