I'm in the process of changing a timing belt on a 2.3L engine. I removed the plugs and set the #1 piston on TDC on the compression stroke. I now have to remove the crankshaft pully. Can someone please tell me how I go about this without turning the crankshaft counter cloclwise?
You may have to move the crankshaft a bit while you loosen the bolt and then reposition it at TDC before you take off the pully. Getting the bolt loose usually isn't too bad, I've used an air impact wrench which doesn't really move the crank but you can also put a socket with a breaker bar on it, rest the bar against the frame rail and bump the starter which pops the bolt free in an instant. But of course you then need to reposition the crank at TDC...
u can also fill the cylinder with nylon rope threw the spark plug hole to break it lose
i do that 1st then break the crank bolt lose then remover the rope an roll the motor to tdc by hand. then u can remover the pully
Many use this method: Use a socket and breakover handle. Put a cheater on the handle long enough to go under the passenger side frame. With the coils disconnected, have a bud hit the starter. This is usually enough to break the bolt loose. I would never put any foriegn material in the combustion chamber. jd
If the belt is being changed for maintenance, the following method can be used, and is much easier for the novice as you don't have to worry about timing.
1: Pull the timing cover and access the belt.
2: Using a light colored marker, mark the belt and the cam sprocket at the same spot on the sprocket and belt in two different places.
3: Do the same with the auxilary sprocket, only space the marks differently so you will know which is which when you reinstall the new belt.
4: Mark the crank sprocket and belt. One mark will suffice as it is hard to access.
5: Remove the timing belt and lay it on top of the new belt lining up the belt teeth.
6: Mark the new belt even with the same marks you made on the old belt.
7: Install the new belt lining up the marks on the belt with the marks on the sprockets.
8: Tighten the idler tensioner.
10: Turn the engine over by hand a couple of revolutions in a clockwise direction when standing in front of the engine (normal crank rotation). Recheck your marks. (Note: Never turn a belted engine in the wrong direction. It is almost guaranteed to skip a couple teeth.)
11: If everything check, complete re-assembly, and drive happy. jd
