Before installing the steering gear, apply a sodium soap
fine fiber grease to the gear mounting pads to prevent squeaks
between the gear housing and the frame. Before positioning
the gear, note the flat on the gear lower shaft must index with
the flat in the coupling flange. Make certain there is a
minimum of .040" clearance betweeen coupling hub and
steering gear upper seal. Install the coupling flange hub bolt
and torque to 30 ft. Ibs. Before tightening the steering gear
to frame bolts, shift the steering gear as necessary to place
it in the same plane as the steering shaft so that the flexible
coupling is not distorted. Tighten the steering gear to frame
