QuestionI INSTALLED A NEW ENGINE AND I HAVE NO INFO ON HOW TO SET OR INSTALL A NO ROTOR NO CAP DISTRIBUTOR CAN YOU PLEASE HELP ME. DO I NEED A SCANNER TO SET
AnswerU can only get it 2 ways there is a key way to which its either 180 out or right.
CAMSHAFT POSITION SENSOR - 4.0L ENGINE
The Camshaft Position Sensor (CMP) on the 4.0L 6 - cylinder engine is bolted to the top of the oil pump drive shaft assembly CMP and Oil Pump Drive Shaft - 4.0L Engine The sensor and drive shaft assembly is located on the right side of the engine near the oil filter CMP Location - 4.0L Engine
The rotational position of oil pump drive determines fuel synchronization only. It does not determine ignition timing.
NOTE: Do not attempt to rotate the oil pump drive to modify ignition timing.
Two different procedures are needed for removal and installation. The first procedure will detail removal and installation of the sensor only. The second procedure will detail removal and installation of the sensor and oil pump drive shaft assembly. The second procedure is to be used if the engine has been disassembled.
An internal oil seal is used in the drive shaft housing that prevents engine oil at the bottom of the sensor. The seal is not serviceable
REMOVAL - SENSOR ONLY
Disconnect electrical connector at CMP sensor CMP Location - 4.0L Engine
Remove 2 sensor mounting bolts CMP and Oil Pump Drive Shaft - 4.0L Engine or CMP Location - 4.0L Engine
Remove sensor from oil pump drive.
INSTALLATION - SENSOR ONLY
Install sensor to oil pump drive.
Install 2 sensor mounting bolts and tighten to 2 N·m (15 in. lbs.) torque.
Connect electrical connector to CMP sensor.
REMOVAL - OIL PUMP DRIVE AND SENSOR
If the CMP and oil pump drive are to be removed and installed, do not allow engine crankshaft or camshaft to rotate. CMP sensor relationship will be lost.
Disconnect electrical connector at CMP sensor CMP Location - 4.0L Engine
Remove 2 sensor mounting bolts CMP and Oil Pump Drive Shaft - 4.0L Engine or CMP Location - 4.0L Engine
Remove sensor from oil pump drive.
Before proceeding to next step, mark and note rotational position of oil pump drive in relationship to engine block. After installation, the CMP sensor should face rear of engine 0°.
Remove hold-down bolt and clamp CMP Location - 4.0L Engine
While pulling assembly from engine, note direction and position of pulse ring CMP and Oil Pump Drive Shaft - 4.0L Engine After removal, look down into top of oil pump and note direction and position of slot at top of oil pump gear.
Remove and discard old oil pump drive-to-engine block gasket.
INSTALLATION - OIL PUMP DRIVE AND SENSOR
Clean oil pump drive mounting hole area of engine block.
Install new oil pump drive-to-engine block gasket.
Temporarily install a toothpick or similar tool through access hole at side of oil pump drive housing. Align toothpick into mating hole on pulse ring CMP Pulse Ring Alignment - 4.0L Engine
Install oil pump drive into engine while aligning into slot on oil pump. Rotate oil pump drive back to its original position and install hold-down clamp and bolt. Finger tighten bolt. Do not do a final tightening of bolt at this time.
If engine crankshaft or camshaft has been rotated, such as during engine tear-down, CMP sensor relationship must be reestablished.
Remove ignition coil rail assembly. Refer to Ignition Coil Removal/Installation.
Remove cylinder number 1 spark plug.
Hold a finger over the open spark plug hole. Rotate engine at vibration dampener bolt until compression (pressure) is felt.
Slowly continue to rotate engine. Do this until timing index mark on vibration damper pulley aligns with top dead center (TDC) mark (0 degree) on timing degree scale Align Timing Marks - 4.0L Engine Always rotate engine in direction of normal rotation. Do not rotate engine backward to align timing marks.
Install oil pump drive into engine while aligning into slot on oil pump. If pump drive will not drop down flush to engine block, the oil pump slot is not aligned. Remove oil pump drive and align slot in oil pump to shaft at bottom of drive. Install into engine. Rotate oil pump drive back to its original position and install hold-down clamp and bolt. Finger tighten bolt. Do not do a final tightening of bolt at this time.
Remove toothpick from housing.
Install sensor to oil pump drive. After installation, the CMP sensor should face rear of engine 0°.
Install 2 sensor mounting bolts and tighten to 2 N·m (15 in. lbs.) torque.
Connect electrical connector to CMP sensor.
If removed, install spark plug and ignition coil rail.
To verify correct rotational position of oil pump drive, the DRB scan tool must be used.
WARNING: WHEN PERFORMING THE FOLLOWING TEST, THE ENGINE WILL BE RUNNING. BE CAREFUL NOT TO STAND IN LINE WITH THE FAN BLADES OR FAN BELT. DO NOT WEAR LOOSE CLOTHING.
Connect DRB scan tool to data link connector. The data link connector is located in passenger compartment, below and to left of steering column.
Gain access to SET SYNC screen on DRB.
Follow directions on DRB screen and start engine. Bring to operating temperature (engine must be in "closed loop" mode)
With engine running at idle speed, the words IN RANGE should appear on screen along with 0°. This indicates correct position of oil pump drive.
If a plus (+) or a minus (-) is displayed next to degree number, and/or the degree displayed is not zero, loosen but do not remove hold-down clamp bolt. Rotate oil pump drive until IN RANGE appears on screen. Continue to rotate oil pump drive until achieving as close to 0° as possible.
The degree scale on SET SYNC screen of DRB is referring to fuel synchronization only. It is not referring to ignition timing. Because of this, do not attempt to adjust ignition timing using this method. Rotating oil pump drive will have no effect on ignition timing. All ignition timing values are controlled by powertrain control module (PCM)
Tighten hold-down clamp bolt to 23 N·m (17 ft. lbs.) torque.
