Ranger 4WD L4-140 2.3L VIN A EFI (1997)
cup is pressed into the bore.
4. Place a new inner pinion bearing over the proper aligning adapter and insert into the pinion bearing retainer.
5. Place the outer differential pinion bearing (new or used if in good condition) into the drive pinion bearing cup in the carrier and assemble the
handle onto the screw and hand tighten. Note the 3/8-inch square drive in the handle to be used for obtaining the proper pinion bearing preload.
6. Center the proper gauge tube into the differential bearing bore. Install the bearing caps and bolts and tighten to 64-91 Nm (47-67 ft. lbs.) for the
Model 35 or 41-61 Nm (30-45 ft. lbs.) for the Model 28
7. To preload the differential pinion bearing, tighten the handle to 1.7-3.9 Nm (15-35 inch lbs.).
8. Using a feeler gauge tool, select the thickest feeler shim that will enter between the gauge tube and the gauge block.
9. Insert the feeler gauge directly along the gauge block. Verify correct reading.
NOTE: The feeler gauge fit between the gauge tube and the gauge block should have a slight drag-type feeling
10. After the correct feeler gauge feel is obtained, check the reading and this is the thickness of the oil slinger required providing that upon inspection
of the service pinion gear, there are no markings.
NOTE: If the service pinion gear is marked with a plus (+) reading, this amount must be subtracted from the thickness dimension obtained in
Steps 8 and 9. (Example: +2 [+0.002]). If the service pinion gear is marked with a minus (-) reading, this amount must be added to the thickness
dimension obtained in Steps 8 and 9. (Example: -2 [0.002]). In addition, use same new inner differential pinion bearing as in the previous steps.
