Torque tol 0%, -15% of torquing values. Unless otherwise specified use torque values listed above.
All locknuts or lubricated fasteners: Use 75% of torque value. (i.e. 1/2"-13 GR5 = 76 ft-lb; 75% of 76 or .75 x 76 = 57 ft-lb
Additional Torque Values
Front Roller Gang Slide
(1" Hex Flange Locknuts)
Tighten 1" nuts until they make contact with gang slide and then back nuts off
1/3 revolution (2 hex flats). Some additional backing off of the nuts may be
necessary to allow the gang slide to move easily. See
“Front Spike Roller
Angle”
on page 36.
