4-CYCLE OVERHEAD VALVE ENGINES - Small Engine Discount

OVERHEAD VALVE TORQUE SPECIFICATIONS
The torque specifications listed in this chart are to be used for replacing components after disassembly, not for
checking an existing engine bolt torque. Checking a torque value on a new or used engine may be lower due
to torque relaxation that occurs on all engines from thermal expansion and contraction. However, sufficient
clamping force exists and a re-torque is not necessary.
Specifications below ten ft. lbs. torque are listed only as in. lb. measurements to encourage the use of an inch
pound torque wrench for greater torque accuracy.
