Ranger 2WD V6-245 4.0L VIN X SFI (1997)
Bell Housing: Testing and Inspection
A concern with the rear deck of the engine would be indicated by:
^
Frequent replacement of pilot bearing and transmission input shaft bearing on manual transmission vehicles. Also hard shifting into high (not
overdrive) gear or jumping out of gear.
^
Frequent replacement of torque converter seals, input shaft seals or bearings, or transmission oil pump on an automatic transmission vehicle.
If cylinder block-to-transmission misalignment is suspected:
^
With crankshaft installed and engine rear plate and flywheel removed, attach Dial Indicator with Bracketry TOOL-4201-C or equivalent to
crankshaft. The dial indicator can be mounted by any method that holds the extension bar so it does not sag.
^
Position the dial indicator on the machined flange slightly in from the left edge.
^
Set the dial indicator on zero mark.
^
Because the shape of the flange is irregular, lift the tip of the dial indicator off of the flange.
^
Rotate the crankshaft to the 12 o'clock position and release the dial indicator tip.
^
Take the reading.
^
Lift the pointer off the flange and rotate the crankshaft so the dial indicator is just on the flange on the right side of the engine.
^
Release the pointer and take the reading. The readings should vary less than 0.076 mm (0.003 inch).
^
Attach Dial Indicator with Bracketry TOOL-4201-C or equivalent to transmission input shaft.
^
Position dial indicator on transmission flange just above and inside of hole for left transmission bolt.
^
Set dial indicator on zero mark.
^
Slowly rotate transmission input shaft and take readings from dial indicator at 12 o'clock position and just above right most transmission-to-engine
bolt hole.
^
Reading should not vary more than 0.076 mm (0.003 inch).
