NOTES:

(1) Lubricants: Molykote G paste, Teflon-base pipe dope, graphite-base grease,

or similar lubricants. Lube first 2 threads only. Do not lube bearing surface.

(2) Torque on bolts is accomplished in 3 or 4 steps. Tighten UNIFORMLY.
(3) Rotation of bolt head is measured after bolt is "snug," with approximately

5 lb/ft torque. DO NOT EXCEED THIS ROTATION. To tighten bolts with-

out torque wrench, use rotation values.

(4) Rotation reference for bolt with nut is the sum total of bolt head plus nut, or

total of 2 nuts.
