Frame Fastener Torque
Requirements
CAUTION
Incorrectly tightening the fasteners may
result in failure of the fastener or incor-
rect clamp loads. Fastener failure may
lead to frame failure. Failure to comply
may result in equipment or property
damage.
• Use a torque wrench for final
tightening of these fasteners.
Due to the coating on the
threads of these bolts, be aware
that if an impact gun is used to
tighten the fasteners, they may
over-torque and break.
• When torquing, the nut must ro-
tate slightly before achieving the
torque value. If the nut does not
rotate, the fastener is over-tor-
qued and should be replaced.
• To achieve correct clamp loads,
the frame fasteners must be tor-
qued with the nut. The intended
clamp load may not be achieved
if the nut is held and torque is
applied to the bolt.
Where Nylon lock-nuts (AKA,
"ESNA" or "nyloc") are indicated in
the following tables
NOTE
The torque values and instructions
found in the following section apply
ONLY to Nylon locknuts (right image).
They do NOT apply to the all-metal
lock-nut type (left image).
