Hope this helps.

The harmonic balancer on these engines is now press fit onto the crankshaft and requires the use of Tool J-38197 for removal. The torque specification to be used during installation has also been revised. The procedure to be used when replacing the crank sensor is as follows:

REMOVAL

1. Disconnect serpentine belt from crankshaft pulley.



2. Raise vehicle on hoist.



3. Remove right front tire and wheel assembly.



4. Remove right inner fender access cover.



5. Using 28 mm socket, remove crankshaft harmonic balancer retaining bolt.



6. Remove crankshaft harmonic balancer using Tool (J-38197).



7. Remove foreign object deflector (DO NOT use pry bar).



8. Disconnect sensor electrical connector.



9. Remove sensor and pedestal from block face.



10. Remove sensor from pedestal

INSTALLATION

1. Loosely install crankshaft sensor on pedestal.



2. Position sensor with pedestal attached on Tool J-37089.



3. Position tool on crankshaft.



4. Install bolts to hold pedestal to block face, torque to (18-26 lb. ft.).



5. Torque pedestal pinch bolt to (26-44 lbs. in.).



6. Remove Tool J-37089.



7. Install foreign object deflector.



8. Place Tool J-37089 on harmonic balancer and turn. If any vane of the harmonic balancer touches the tool, replace the balancer assembly.



9. Install balancer on crankshaft.



10. Apply thread sealer GM #(NNN) NNN-NNNNor equivalent to threads of crankshaft balancer bolt. Torque bolt to + 56 degrees (104 lb. ft. + 56 degrees).



11. Install inner fender shield.



12. Install tire and wheel assembly. Torque lug nuts to (104 lb. ft.).



13. Lower vehicle.



14. Install serpentine belt.

the garage may have did something to the crank position sensor that is located behind the harmonic balance. there is a ring gear there to for the timing

how can i set a toyota 1rz engine on timing

Hi,
The sensor is located to the right of the crankshaft behind the vibration dampner (harmonic balancer). You will need a balancer puller and a special tool to space the new sensor correctly.
(can be done also with eye spacing, but the tool is recommended to ensure proper spacing as to prevent damage to new sensor and / or harmonic balancer.) You will also need a strap wrench to hold balancer pulley in place while removing and re-installing balancer to crankshaft bolt. (helper required)

Procedure for replacement:
Remove negative battery cable.
Set parking (emergency) brake.
Release tension on serpentine drive belt and remove belt from harmonic balancer pulley. ( large pulley at bottom of engine)
Break loose lug nuts on passenger side front tire, do not remove bolts yet.
Raise and support vehicle on passenger side, remove wheel.
Remove plastic splash guard (cover) from passenger side wheel well.
Remove dampner / balancer center retaining bolt (counterclockwise, it is torqued very tight.) Use a strap wrench around pulley and have a helper hold that in place while using a 1/2" breaker bar and socket to turn pulley bolt out of crankshaft. Be careful not to rotate engine in a counterclockwise direction while breaking the bolt loose.
Using balancer puller, remove dampner / balancer pulley from engine.
You will now see the crank sensor to the right of the crankshaft bolted to the timing cover.
Disconnect sensor wiring and remove retaining bolts, remove sensor.
Put new sensor in place and screw in bolts, do not tighten them yet.
Reconnect wiring to sensor.
Now use special tool to properly space sensor. If you cannot find one at the parts store, you can space the sensor with the balancer pully held in place (not installed yet) and space the sensor evenly with the veins on the hub of the balancer pulley. Take your time and be sure it is as evenly spaced as possible.
Tighten sensor bolts.
Clean balancer hub free of any oil and dirt deposits using brake or carbeurator cleaner.
Reinstall balancer to crankshaft by tapping around the inner surface of pulley with a rubber hammer.
It is a press fit, so be sure you have it started evenly and progress slowly in a circular motion to ensure you are keeping it aligned straight with the crankshaft.
Reinstall balancer bolt using the same method as removal, torque bolt to 110 foot pounds, then tap around balancer again twice with rubber hammer, turn the engine 2 full revolutions clockwise using the balancer to crankshaft bolt, then tighten bolt an additional 1/4 turn.
Replace splash guard, put wheel on tightening lugs to finger tight and then wrench tight in a star pattern.
Lower vehicle until wheel makes contact with floor, tighten lug nuts to 115 foot pounds in a star pattern using a torque wrench.
Fully lower vehicle, remove jack.
Re-install serpentine drive belt
Re-connect negative battery cable.

End of procedure....Hope that helps!.....Mike

TURN CRANKSHAFT BOLT COUNTERCLOCKWISE TO LOOSEN. YOU HAVE RIGHT HAND THREADS.ENGINE TURNING CLOCKWISE.YOU NEED A STRAP WRENCH HOLD CRANKSHAFT PULLEY WHILE LOOSEN IT.BUT YOU NEED A CRANKSHAFT DAMPER REMOVAL TOOL.OR HARMONIC BALANCER REMOVAL TOOL.YOU NEED STRAP WRENCH TO HOLD CRANKSHAFT PULLEY WHEN TIGHTEN IT.TORQUE CRANKSHAFT PULLEY BOLT 90 - 98 FT LBS. MAKE JOB EASIER.HAVE A HELPER HOLD STRAP WRENCH WHEN YOU LOOSEN OR TIGHTEN CRANKSHAFT PULLEY.

WARNING
This procedure requires the removal of the timing belt. This is an extensive procedure requiring precision work, particularly at assembly. For more information, refer to Timing Belt Removal and Installation. Do not attempt to remove the belt without consulting the procedure; extreme engine damage may occur.

1. Drain the cooling system.
2. Remove the timing belt. For additional information, please refer to the following topic(s): Timing Belt Removal and Installation.
3. Remove the idler pulley.
4. Remove the thermostat.
5. Disconnect the oil cooler hose from the pump.
6. Remove the seven bolts and the tension spring bracket and then remove the water pump. To install:
   
7. Clean all parts well. It is good practice to carefully clean all threaded openings, especially those exposed to coolant to remove rust and scale so at assembly, an accurate torque reading is obtained. This is important since gasketless applications like this depend on even clamp loads from the fasteners to avoid distortion and leaks. Remove any old sealer (Toyota calls it packing) from the pump and mounting area of the engine. Keep oil off the mating areas.
8. Apply Formed In Place Gasket (FIPG) sealer to the pump-to-block mating surface and then tighten the bolts marked A in the illustration to 13 ft. lbs. (18 Nm). Tighten those marked B to 14 ft. lbs. (20 Nm). NOTE: The parts must be installed within 5 minutes of application of the sealant. Otherwise you must remove and reapply the sealer.
   
9. Connect the oil cooler hose.
10. Install the thermostat with a new gasket.
11. Install the idler pulley.
12. Install the timing belt.
13. Install the drive belts and adjust the tension.
14. Refill the cooling system and check for leaks.

4. Remove the fluid coupling with the fan and water pump pulley.
5. Remove the water pump. To install:
   
6. Clean the gasket mounting surfaces.
7. Install the replacement water pump using a new gasket.
8. Install the water pump pulley and fluid coupling with the fan.
9. Install the removed engine drive belts.
10. Fill the cooling system.
11. Connect the negative battery cable. Start the engine and check for leaks.
12. Bleed the cooling system.

It is not complicated, depending on what hands-on level of DIY on car. Here are what need to do, so you can estimate how easy or hard when you look through your engine. Drain all the coolant, remove the thermostat housing, remove the fan, belt. Remove the water pump pulley. There are 4 bolts to hold the water pump in place.If you think you can take them out and put them in without removing the AC compressor then you can do it. I did it twice without removing the AC. The pump was fine for the second time, but for leaking seal. At dealer, it is easier to access from the bottom since they have a lifter. But it is doable at home. Have fun if you decide to do it.
