Ranger 4WD V6-245 4.0L VIN X SFI (1999)
CAUTION: Do not turn the crankshaft or camshaft during the removal and installation procedure or the fuel system timing will be out of time with
the engine, and possibly cause engine damage.
CAUTION: A special tool must be used during the installation of the new synchronizer assembly. Failure to follow this procedure will result in the
fuel system being out of time with the engine, possibly causing engine damage.
1. Install the special tool on the camshaft synchronizer by rotating the tool until it engages the notch in the camshaft synchronizer housing and the
armature.
CAUTION: It is very important to coat the gear on the camshaft synchronizer with super premium motor oil or equivalent, prior to installation.
Failure to do so could result in gear failure.
Note: During installation, the arrow on the special tool will point to 60 degrees off the engine centerline, then rotate clockwise until the oil pump
intermediate shaft and camshaft gear engages.
2. Install the camshaft synchronizer housing assembly so the arrow on the special tool is 15 degrees from the centerline of the engine.
3. Install the bolt.
4. Install the camshaft position (CMP) sensor. For additional information, refer to Camshaft Position (CMP) Sensor in this section. See: Camshaft
Position (CMP) Sensor
