Power Steering Pump Ford LTD Crown Victoria I

DESCRIPTION

The C-II pump is a belt driven, ten slipper pump which has an integral fiberglass nylon reservoir. Spring loaded slippers within cam and rotor create the pumping action. A flow control relief valve maintains pump volume and pressure.

The pump design incorporates a pump pressure fitting which allows the pump pressure line to swivel; this is normal and does not indicate an under-tightened fitting. An identification tag attached to reservoir body indicates pump model. Use model code when requesting service parts, as slight differences in internal components do exist.

TROUBLE SHOOTING

Refer to TROUBLE SHOOTING - BASIC PROCEDURES article in the GENERAL TROUBLE SHOOTING section.

LUBRICATION & TESTING

For further information see POWER STEERING GENERAL SERVICING article in the STEERING section.

PUMP BELT TENSION

Note. Pump drive belt tension with Belt Tension cannot be checked using the thumb pressure or belt deflection methods. Adjustments must be made with a belt tension gauge.

Conventional "V" Belt System

Check the belt tension with Belt Tension Gauge (021-00019) or 021-00021 or equivalent). New belts with less than 15 minutes use should have a tension of 120-150 ft. lbs. (534-667 N.m). Belts that have been run for longer than 15 minutes, should have a tension of 110-130 ft. lbs. (401-533 N.m) for 3/8" "V" belt.

Pivot System Adjustment

Loosen pivot bolt and insert proper tool into square hole in pivot bracket. Lift up on pivot bracket to obtain proper belt tension and tighten pivot bolt to proper specification.

Fixed Pump System Adjustment (2.3L Engine)

Belt tension is adjusted by pivoting alternator. Do not try to pry against reservoir to obtain proper belt tension. Pressure on fiberglass reservoir may crack the reservoir.

Note. Do not pry against reservoir to tighten belt. Pressure on fiberglass may crack reservoir.

Removal & Installation (RWD Models)

Drain reservoir by disconnecting fluid return line at reservoir. Disconnect pressure hose at pump and remove bolts from mounting bracket. To install, reverse removal procedure. Adjust belt tension. Refill and bleed pump.

2. Remove 4 bracket mounting bolts. Using Pulley Remover (T69L-10300-B), remove pulley. Remove pump from bracket. To install, reverse removal procedures. Using Pulley Installation Tool (T65P-3A733-C), install pulley. Adjust belt tension. Refill and bleed pump.

Removal & Installation (Escort, EXP & Lynx, Except Diesel, & All RWD Models)

With pump removed from vehicle, drain as much fluid as possible through filler neck. Install Pulley Remover (T69L-10300-B) on pulley hub and remove pulley. To install, reverse removal procedure. Using Pulley Installer (T65P-3A733-C), install pulley flush with shaft.

Note. When removing pulley, do not apply in and out pressure on pump shaft. Damage to internal thrust areas could result.

Removal & Installation (Gasoline Tempo & Topaz)

Remove radiator overflow tank. Mark pulley and hub position. Remove 3 bolts and 2 pulleys from pump. To install, align pulley and hub, then reverse removal procedures.

Removal & Installation (All other Gasoline Models)

1. Remove radiator overflow tank to access pulley attaching screws. Mark pulley-to-hub position for reassembly to maintain balance.
2. Remove pulley attaching bolts, and remove pulley. To install, reverse removal procedures.

Removal & Installation (All Models with 2.0L Diesel)

Remove drive belts. If equipped with A/C, remove alternator support bracket and alternator. Disconnect pressure lines and drain fluid from pump. Remove 4 counting bracket bolts. Using Pulley Remover (T69L-10300-B), remove pulley. To install, reverse removal procedures. Using Pulley Installation Tool (T65P-34A733-C), install pulley. Adjust belt tension. Refill and bleed air from pump.

Removal & Installation

Place pump in vise and remove outlet fitting, flow control valve and spring. Remove reservoir by twisting side to side and lifting. Discard "O" ring. To install, apply petroleum jelly to new "O" ring, and reverse removal procedure.

Scheme 1

1. Remove pulley, outlet fitting, flow control valve and spring. Remove reservoir from pump. Mount "C" Clamp (T74P-3044-A1) vertically in vise with screw at top. (Scheme 1): Pump Positioned in "C" Clamp
2. Place Lower Support Plate (T78P-3733-A2) over pump rotor shaft. Install Upper Support Plate (T78P-3733-A1) into upper portion of "C" clamp. Place pump, shaft down, into "C" clamp and tighten until a slight bottoming of valve cover is felt.
3. With a small drift punch, push inward on retaining ring through hole in side of pump housing. Using a screwdriver, pry retaining ring from housing. Loosen "C" clamp, remove upper compressor plate, and remove pump. Remove pump valve cover and discard "O" ring seal.
4. Push on rotor shaft to remove shaft, upper plate, rotating group assembly and 2 dowel pins. To remove cover plate and Belleville spring, slam pump housing on flat surface. Discard "O" rings. Pry rotor shaft seal and seal retainer from housing.

Disassembled Pump. Scheme 2

Scheme 3

Scheme 4

1. If rotating group was disassembled, place rotor on spline shaft. Rotor is symmetrical, and can be installed either way. (Scheme 3) Install retaining ring at end of shaft. Place insert cam over rotor with recessed notch on cam facing up.
2. With rotor extended approximately half way out of cam, insert one spring and slipper (groove facing the cam profile) into one of the rotor cavities beneath recessed cam flats. Then repeat the procedure on the cavity opposite the one installed.
3. Index cam either one space right or left at a time about rotor. Insert remaining springs and slippers until all 10 cavities are filled. Turn rotor carefully so that previously installed springs and slippers do not fall out.
4. Install rotor shaft seal with Seal Driver (T78P-3733-A3). Drive seal into bore until it bottoms. Install seal retainer in same manner. With pulley side of housing facing down, insert 2 dowel pins and Belleville spring (dished surface upward) into housing. (Scheme 3): Assembling Cam and Rotating Assembly
5. Lubricate inner and outer "O" rings with power steering fluid and install on lower pressure plate. Insert lower pressure plate over dowels and into housing with seals facing front of pump.
6. Install pump into "C" clamp and using Seal Driver (T78P-3733-A3), press lower plate lightly into housing until it is felt to bottom.
7. Install cam, rotor and slippers, and rotor shaft assembly over dowel pins and into housing. (Scheme 3) Place upper pressure plate over dowel pins with recess directly over recessed notch on cam insert and approximately 180° opposite square mounting lug. (Scheme 4) (Scheme 4): Upper Pressure Plate Installation NOTE: Stepped holes must be used for dowel pins and recessed notch in cam insert must face toward reservoir approximately 180° opposite square mounting lug on housing.
8. Lubricate and place new "O" ring on valve cover. If plastic baffle is loose in valve cover, apply petroleum jelly to baffle and install into position on valve cover. Insert valve cover over dowel pins with outlet fitting hole directly in line with square mounting lug on housing.
9. Place assembly in "C" clamp and compress valve cover into pump housing. Install retaining ring with ends near access hole in housing. Lubricate and install "O" ring on pump housing and install reservoir.
10. Install flow control valve and spring into valve cover. Use new "O" ring seals on outlet fitting and install into valve cover to specified torque. If flow control valve is cocked, it may become stuck in valve cover. Do not force valve forward since chips may shear off and carry into valve bore.
11. Lubricate and place new "O" ring seals in the outlet fitting. Install the outlet fitting into the valve cover, and tighten to 25-34 ft. lbs. (34-46 N.m)
