Install and hand tighten Branch Tee to pump until O-ring is
seated. 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
Branch Tee. This is acceptable unless there is seepage at
the O-ring. If so, slightly tighten the locknut.
CAUTION
Over tightening locknut may tear O-ring or
distort threads in pump manifold outlet.
10. Hoses: Clean adapters and hose. Inspect all threads
for damage and hose ends to be sure they are crimped,
Fig. 10. Install hose and hose clamps, Fig. 12 & Fig. 16.
Flared Fittings Tightening Procedure
1. Screw the fittings 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.
