What do i need to do to break loose the crankshaft pulley bolt

Remove old crankshaft pulley ( Harmonic Balancer), by putting sturdy socket,think its 19mm, or 3/4 " on the center crankshaft bolt, with a good size breaker bar, wedge the breaker bar in between the suspension, and drive axle, to keep the breaker bar from spinning, while, you now turn the key inside the car, to engage starter, to spin the crankshaft,which may take several attempts, of turning the key, and putting socket back on, they are very stubborn,to break the center bolt loose,
Then remove harmonic balancer, with a PULLER, which requires 2 bolts, in the threaded holes, one on each side of the now empty center bolt hole, autozone , advance, has these to loan out, only requires deposit, which they give back to you, when you return it.
Put square key in slot on bare crankshaft, slide harmonic balancer,(crankshaft pulley,while lining up the square key,and tighten crankshaft bolt.

check the bolt holes and bolts to inspect for damaged threads and repair or replace as needed. if this is good you may need to add Loctite to the threads of the bolts. use blue Loctite as this will allow removal later on if you need to remove the bolts.

Ok it seen that u having problems to break loose u crank shast pulley bolt if u don't have the proper tools to get it loose, I will suggest to do this but you goin to be carefull how to do it. Get a good side breaker bar with the sucket that fit in the bolt connect the battery back is possible that you have everything disconected but go head and install the battery cable back, with the braker bar find a spot to put the breaker bar agians too. Have somebody to go inside of the car to just try to bump the engine wich mean with the ignition switch try to start the car make sure u have the breaker bar set up to the left not to right possition(lefty loosy and righty tighty) and it will break loose

CHECK SEE IF CRANK SHAFT PULLEY BOLTS LOOSE.IF CRANKSHAFT PULLEY LONG BOLT TORQUE IS FOR 130 FT LBS FOR 1.8L ENGINE. IF YOU HAVE THESE ENGINES CRANKSHAFT BOLT TORQUE IS 174 - 181 FT LBS ENGINES ARE 3.0L 3.2L 3.5L 2.3L 2.5L IF CRANKSHAFT PULLEY BOLT IS TIGHT.THE CRANKSHAFT PULLEY ITSELF BROKEN NEED REPLACING.

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

The crankshaft pulley bolt loosens by turning Counter-Clockwise. Ensure the pulley is secure from movement so that you can loosen the pulley bolt without turning over the engine. You may need to use breaker bar to loosen the pulley bolt, or at least a large wrench.

If it's the main pulley that connects to the crankshaft and drives the serpentine belt, it's called the dampener pulley.
If the dampener pulley has worked loose or separated, you'll need to replace any damaged components, possibly including the pulley, mounting bolt and even the crankshaft and front engine housing could have been damaged if the pulley continued to turn while it was loose.
It could be as simple as tightening the bolt or as severe as a major engine rebuild. A mechanic can't know until he takes a look at it.

Yes you can. There is a woodruff key on this pulley so be sure to get a new key if your was lost. I'm assuming you are talking about the external pulley that spins your accessory drive belts (A/C, alternator, power steering) So, I have to ask the obvious question. . .How the heck did your pulley fall off the crankshaft? The bolt that holds that on is usually so tight that you need a 4 foot breaker bar to break it loose.

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.

This is a simple problem to solve.
To replace the timing belt the mark on the camshaft pulley should be aligned with the engine block/valve cover and the mark on the crankshaft pulley should be aligned with the mark on the engine block.
The marks may be a white mark or an indentation.

When this is done one of the cylinders will be at TDC (Top Dead Center). In this position the ALL THE INTAKE AND EXHAUST VALVES IN THAT CYLINDER WILL BE CLOSED (compression stroke). Get the correct cylinder. Remove the spark plug in that cylinder. Back off the piston slightly and pack a length of a small diameter rope into the spark plug hole until full. Leave one end out for removal! Now when you turn the crankshaft nut the piston will push against the rope and the engine will not turn. You can get a manual from the library, auto supply shops or internet.

Some books suggests compressed air with a sparkplug adapter. That's elaborate and too noisy.

Make sure those marks are aligned on final assembly ! The valves will hit the pistons if not.
