Mercury Parts Questions & Answers

• Oil Pump Assembly
  F3ZZ-6600-A
  Q: How to remove and install the oil pump and ensure proper oil pressure in four cylinder engine on Mercury Capri?

  A: Remove the oil pan. Next, take off the nut securing the pick-up tube to the engine, followed by the bolts securing the pump to the engine. Remove the pump and pick-up tube as an assembly, then separate them once they are off the engine. The pump intermediate shaft should drop out of the bottom of the distributor shaft during this process. If there is any possibility that the pump is faulty or if an engine overhaul is being performed, replace the pump, as a faulty pump can ruin an otherwise good engine. Before installation, prime the pump by holding it with the pick-up tube up and pouring a few ounces of clean oil into the inlet screen. Turn the pump driveshaft by hand until oil comes out the outlet. Install the pump intermediate shaft with the collar end in the engine block, ensuring the shaft seats in the distributor. Hold the shaft in place and install the pump and oil pan, making sure to tighten the bolts to the specified torque. Add oil to the engine, then start it and ensure the oil pressure comes up. If it doesn't come up within 10 or 15 seconds, shut off the engine immediately and investigate the cause of the problem, as continued running without oil pressure can severely damage the moving parts. Finally, check for oil leaks.
• Remanufactured Cylinder Head Kit
  F4DZ-6V049-BRM
  Q: How should the Cylinder Head be prepared for reassembly after valve servicing on Mercury Cougar?

  A: Regardless of whether the head was sent to an automotive repair shop for valve servicing, ensure it is clean before beginning reassembly. If the head was sent out for valve servicing, the valves and related components will already be in place. Lubricate and install the valves, then install new seals on each of the valve guides. Using a hammer and a deep socket, gently tap each seal into place until it is properly seated on the guide, avoiding twisting or cocking the seals during installation to ensure proper sealing on the valve stems. Since the intake and exhaust valves exhibit different leakage rates, the valve stem seals must not be interchanged. Install the valve spring shim(s) over the valve guide boss and set the valve spring, retainer, and sleeve in place. Compress the spring and install the keepers, ensuring they are seated properly in the valve stem grooves. Grease can be used to hold the keepers in place until the compressor is released. Check the installed valve spring height for each valve, ensuring it remains within specified limits; if not, install additional valve spring shims to achieve the correct height. Finally, install the rocker arms, fulcrums, and bolts, lubricating the fulcrums with moly base grease or engine assembly lube.
• Lamp Assembly
  6W3Z-13008-BA
  Q: How should headlights be aimed correctly to ensure safety on Mercury Grand Marquis?

  A: Coming to the headlights, they must be properly aligned so that it does not dazzle other road users and as-well-as to get the right projections on the roads, and the alignment is advised every 1-year or after the car has had new headlights or front-end body work done to it. The adjustment involves two spring-loaded screws: Other designs are likely to incorporate two wheels, one at the top to allow for the up and down motion and the other at the side for the forward and backward motion. In the models prior to 1991, these screws can be removed and replaced after you have removed the bezel and the screws are visible from the front and the models from and after 1992, these screws can be undone and tightened from behind the headlight with the help of a small wrench or pliers. To align the headlights you have to park the car facing a blank wall at a distance of 25 feet as what is recommended by the manufacturer and then use a masking tape to mark the middle line of the car, the middle line of each of the headlights and a horizontal line of the masking tape for height alignment. Make certain that is as level as possible, the gasoline gauge showing precisely the middle of full and empty and with no excessively heavy equipment on board. Turning the screws slightly, for low beam adjustment place the high-intensity zone two inches below the horizontal line and two inches towards the side of the road from oncoming vehicles. When using the high beam the high intensity zone should be a little below parallel to the higher horizontal part of the rectangle but one must remember that the low beam is of more use in aspects of safety. The best action is to have the headlights aligned as professionally as possible at the initial sign of a problem.
• Bearing Cone And Roller
  E7TZ-1216-A
  Q: How to adjust the wheel bearings after removal and refitting on the front of a Mercury Bobcat?

  A: The following adjustment should be carried out at specified intervals or after the hub has been removed and refitted. Begin by chocking the rear wheels and applying the parking brake, then jack up the front of the car and support it on firmly based stands. Remove the hub cap and ease off the grease cap from the hub. Wipe the excess grease from the end of the spindle, then remove the cotter pin and nut lock. Slowly rotate the wheel and hub assembly while tightening the adjusting nut to a torque wrench setting of 17 to 25 lbf ft (24 to 33 Nm) to seat the bearings. Using a box spanner, back off the adjustment nut by one half of a turn and then retighten it to a torque wrench setting of 10 to 15 lbf in (1 to 1.7 Nm) or finger tight. Ensure that the castellations on the nut lock align with the cotter pin hole in the spindle. Fit a new cotter pin and bend the ends around the castellated flange of the nut to prevent interference with the grease cap. Check that the wheel rotates freely, then refit the grease cap and hub cap before lowering the car to the ground. Additional lubricant should not be required during the adjusting operation; however, if there has been severe leakage of grease through a faulty seal, the seal must be renewed and the lubricant replenished.
