14. Cable Adjustment:
Adjust cable with lift fully lowered. Loosen jam nut and
tighten nut on cable stud on top of column until yoke end
raises 1/4" (6mm). Back off nut one turn. Retighten jam nut.
Repeat for all four cables. Cables must fit in slack cable arm
rollers, Fig. 19.
15. Power Unit:
A. Put (4) M8-35 hex bolts through holes in column bracket
using push nuts to hold in place.
B. Mount power unit, with motor up, to column bracket
and install lock washers and nuts, Fig. 20. Run hydraulic
hose from runway through slot in side of runway to
power unit output port, Fig. 22. DO NOT use Teflon tape
on hydraulic hose connections.
C. Install and hand tighten elbow to pump until O-ring
is seated and elbow is oriented downward at
approximately 45°, Fig. 21. Continue to tighten the
locknut to 10-15 ft-lbs. (14-20 Nm), or until the nut and
washer bottom out against the pump manifold. NOTE:
You may still be able to rotate the elbow. This is
acceptable unless there is seepage at the o-ring. If so,
slightly tighten the locknut.
D. Run hydraulic hose from runway through slot in side
of runway to elbow, Fig. 22. DO NOT use Teflon tape on
hydraulic hose connections. Clean elbow and hose.
Inspect all threads for damage and hose ends to be
sure they are crimped. Attach hose to elbow using
Flared Fittings Tightening Procedure.
Flared Fittings Tightening Procedure
1. Screw the fitting together finger tight. Then, using the
proper size wrench, rotate the fitting 2-1/2 hex flats.
IMPORTANT
Flare seat MUST NOT rotate when
tightening. Only the nut should turn.
2. Back the fitting off one full turn.
3. Again tighten the fittings finger tight; then using a
wrench, rotate the fitting 2-1/2 hex flats. This will
complete the tightening procedure and develop a
pressure tight seal.
CAUTION
Overtightening will damage fitting resulting
in fluid leakage.
