REMOVAL AND INSTALLATION
Oil Pan, Ranger
Removal
1. Remove the engine (6007) as detailed in this section.
2. CAUTION: Mounting the engine upside down on the engine stand before removing the oil
pan (6675) may cause sludge to drop into the cylinders and onto the camshaft (6250) and
valve tappets (6500) causing rapid wear when the engine is restarted.
Mount the engine on an engine stand with the engine upright . Remove the oil pan and crankshaft
oil windage baffle (6L680).
3. Rotate the engine upside down and remove the oil pump (6600) and rear main bearing cap.
4. Remove and discard the crankshaft rear main seal.
Installation
1. CAUTION: Prevent engine assembly contamination. Always use necessary precautions
to prevent old sealer or gasket material from falling into the engine.
Thoroughly clean ALL the oil and the old sealer from the oil pan taking special care to remove ALL
the old sealer from the oil pan gasket groove in the oil pan. Thoroughly clean the oil pan.
2. NOTE: Thoroughly clean all exposed areas with metal surface cleaner F4AZ-19A536-RA or
denatured alcohol. Place special attention on removing the remains of the integral rubber
wedge seal. The tabs on the wedge seal tear away from the oil pan gasket when the oil pan is
removed and remain lodged between the block and the rear main bearing cap.
Thoroughly clean ALL the old sealer from the rear main bearing cap using a scraper and wire wheel.
The original sealer used during production assembly becomes extremely hard after it has cured. It is
extremely important that ALL old sealer is removed from all joining faces and grooves.
3. Thoroughly clean ALL oil and old sealer from the cylinder block oil pan sealing area and the rear
main bearing cap joint area.
4. Thoroughly clean ALL oil and old sealer from the area at the rear main bearing cap.
5. After all parts have been thoroughly cleaned and washed, it is necessary and extremely important
that they be wiped down with Extra Strength Spot and Stain Remover B7A-19521-AA meeting Ford
specification ESR-M5B197-A or denatured alcohol.
6. Thoroughly clean the transmission bell-housing area and the rear of the cylinder blocks (6010). Oil
removal should be verified with an ultraviolet lamp ("black light").
7. Apply a bead of Ford Gasket Eliminator E1FZ-19562-A or Loctite® 515, or equivalent sealer meeting
