DESCRIPTION

The Ford-Thompson power steering

pump is a belt driven slipper type

pump which is integral with the reser-
voir (Fig. 1). It is constructed so that

the reservoir is attached to the rear

side of the pump housing front plate
and the pump body is encased within

the reservoir (Fig. 2).

IN-VEHICLE ADJUSTMENTS AND REPAIRS

PUMP BELT TENSION

ADJUSTMENT

Pump drive belt tension cannot be

checked accurately using the
•
thumb

pressure or belt deflection methods.

Correct belt adjustment is assured

only with the use of a belt tension

gauge.

1.
Check the belt tension with a

belt tension gauge tool T63L-8620-A.

With a new belt, or one that has been

run for less than 15 minutes, the ten-

sion should be within 120-150 lbs.

With a belt that has been run for

more than 15 minutes, the tension

should be within 90-120 lbs.

2.
To adjust the belt, loosen the

mounting bolts incorporated on the

front face of the pump cover plate

(hub side) and one nut at the rear of

the reservoir. Fix a 9/16 inch open

end wrench on the nrojecting 1/2 inch

boss on the cover -'plate a"hd pry up-

ward to correct tension on 6 cyl. en-

gines.

MAJOR REPAIR OPERATIONS

DISASSEMBLY

Disassembly of the pump and its

subassemblies must be made on a

clean work bench. In repairing any

hydraulically operated unit, cleanliness

is of utmost importance. Clean the ex-

terior of the unit with a suitable sol-

vent and drain as much of the fluid as

possible.

If only the reservoir is to be re-

moved, plug the inlet and outlet open-

ings with masking tape or plugs. Do

not immerse the shaft oil seal in sol-

vent. If only the rotor shaft seal is to

be replace, see Rotor Shaft Seal Re-

placement outlined in this section.

1.
Assemble the adapter plate (Tool

T69P-3A674-A) to the bench mount-

ed holding fixture Tool T57L-5OO-A

(Fig. 8).
