Hose Installation

Hose Fittings
Lubricate the "O" rings for the high pressure fittings with power steering fluid before installation.
The high pressure fitting torques are not to exceed 20 Ft. Lbs.
Over tightening may result in failure of the "O" ring seals.

Tip: A good rule of thumb - tighten approx. 1/4 turn after you feel the "O" ring seat.
The fittings are designed to allow the line to swivel slightly even after torquing.

Suggested Order of Hose Installation -
1. Booster Inlet to Power Steering Pump
2. Booster Outlet to Gear Box
Tip: Use some cord or wire to support these two hoses from the master cylinder during install
to prevent rotation and "O" ring damage.
3. Return Lines - starting with the Power Steering Pump (short hose).
