Attaching Cross Arms
•
The Cross Arms are bolted to the flange bearings by 5/16” x 1” hex bolts.
•
Don't forget the spring lock washers under the bolts!
•
If the bearing is turned in its housing, it may be necessary to twist it into alignment in
order to fit the 5/8” bolt head in to the clearance hole in the Bearing Plate.
•
Start bolts by hand, and tighten to 9 ft-lbs (108 in-lbs) torque.
•
Note the Counterweight Arm and Shock mounting nuts on the North Cross Arm. Both
bearings should be flush with the top of the Cross Arms.
Shock, Bumper Bolt, and Counterweight Installation
•
Bolt the upper half of the Shock to the Cross
Arm using the 1/2” x 2” hex bolt and hex nut.
•
Do not tighten down on the urethane bushing –
there should be enough play to allow free
movement of Shock eye (approx. 1/16”).
•
Attach the lower half of the Shock using the 1/2”
x 2-1/2” hex bolt and hex nuts.
•
Using two 3/4” wrenches, tighten the nuts to 40-
50 ft-lbs torque.
•
The Bumper Bolt does not need to be tightened
between the head of the bolt and the jam nut.
•
Using the 1-1/2” wrench or adjustable
wrench,tighten the Bumper Bolt jam nut against
the welded nut to 75 ft-lbs.
•
Install the counterweight as shown. At this point,
the position of the Counterweight is not critical.
Somewhere close to the lower 2/3 of the
adjustment range is a good starting point.
