NOTICE:
1.
Torque valves are based on standard lubrication.
2.
If threads have no lubrication (i.e. dry threads), torque values should be increased by
33 %.
3.
If threads have been lubricated with a performance lubricant (e.g. NeverSeez®), torque
values should be decreased by 50%.

NOTICE:
An induction type bearing heater is required to expand bearings to ease their installation on
shaft. Bearings should be heated to approximately 100°C (212°F).
CAUTION:
Do not use a flame to heat bearings, this will damage bearing surfaces.
