From my 73 FSM, sorry no 74
On the 1.06 pump (Fig. 34) when the fluid is
checked when hot, the fluid level will be approximately
1/2 to 1 inch below the top of the filler neck.
At room temperature (approximately 70 degrees F.)
the fluid level should be above the joint of the filler
neck and reservoir (between 1-1/2 to 2 inches below
the top of the fiiller neck).
Units equipped with a dipstick (Fig. 35) should be
filled to the required indicated oil level.
If necessary to add fluid to restore these levels, use
only petroleum fluids specially formulated for minimum
effect on the rubber hoses, Power Steering
Fluid. Part Number 2084329, or its eqpivalent, is recommended.
Caution: Do not use Automatic Transmission
Fluid.
