'99 4 cyl timing belt replacement

hawkaye -> '99 4 cyl timing belt replacement (2/12/2008 12:14:39 PM)
I am replacing the timing belt on my '99 4 cyl. The crankshaft pulley bolt will not loosen using my electric impact wrench. I have a large breaker bar and can put about 600 ft lbs of torque on the bolt, but the engine turns over. How do I "lock" the crankshaft in place so that I can apply the necessary torque on the bolt? My Haynes manual says "remove the flywheel/driveplate cover and use a prybar wedged against the ring gear teeth or a converter bolt to hold the crankshaft while loosening the pulley bolt ... " I believe I have found the cover they are refering to, but it appears I would have to remove the bolts which fasten the transmission to the engine to get the plate off. Any suggestions? Will I have to $pring for a pneumatic high-torque impact wrench to get this crankshaft pulley bolt off? Any Toyota mechanics out there who can tell me what they do in their Toyota Service Dept?

Yes, an air impact wrench should do the job but first try this: Look at the front of the pulley and you should see two small threaded bolt holes on the face. These are the same holes used to attach the puller. Don't use a jaw type puller that pulls from behind or the pulley could be damaged (it is 2 pieces held together by a rubber material). You want to find a piece of wood or something else that can be attached to the pulley using the bolt holes. The threaded holes are standard metric sizes available at any decent hardware store. The piece bolted to the pulley should long enough that when the pulley rotates the board, etc. binds with the floor or a solid part of the car and thus keeps the pulley from rotating. When making this part drill a hole for the socket and wrench extension to access the bolt. The above method works very well and can also be used to install the bolt.

Yes. I do see those two threaded holes. I'll find a piece of scrap wood and see if I can make something that will work. It seems like your suggestion should work. I'm wondering if TMC has a tool made just for this purpose. Thanks for the input. I intend to change the timing belt next week. I'll let you know how it works.

Toyota does have a special tool for this job. It looks like a round flat plate with a hole in the center that bolts to the pulley. The handle bolts to one side of the plate.

That procedure works very well, indeed! I now have a new timing belt on my friend's Camry and everything is purring nicely. Thanks for the suggestion!

Great!
