Question balance shaft belt and timing belt

ok, i am needing to replace my balance shaft belt, and i'm going to replace my timing belt while i am at it, i have the kriket tool and the settings for it. my question is, how do i go about removing these belts, i have a haynes book and that says nothing about the belts. if you have replaced these belts before, your input would be greatly appreciated. i don't have any "special tools" other than the kriket tool, and a vast selection of normal hand tools (aka metric socket set, just about any non special tool available) thanks for the help. matt

I have a Haynes manual and followed it when I did my belts. In one spot it says that it should be performed by a dealer but in another spot it gives you the instructions on how to do it. You can also look at <a href="http://www.clarks-garage.com/" target="_blank">http://www.clarks-garage.com/</a> for instructions. The only special tools that are needed are a flywheel lock so you can lock up the flywheel while removing the crank pulley and a spanner to remove the balance shaft rollers. If you find a set of 90 deg. needle nose pliers you may get by without the spanners.

If you are just replacing the belts and not doing seals you do not need to remove the crank pulley, if you are careful you can weasel the cam belt past the outer pulleys, this will save a lot of time and agro. Good luck Mark T.

P.S. when you are finished make sure to turn the engine over by hand before starting it up, if there is a problem you will feel it and stop before any damage is done. It is possible for the cam to spin on its own and cause all sorts of problems.

MHT it seems like you have done a few of these before. When you weasel the timing belt on, be careful not to force it or it will damage the belt. If you do it that way, you won't need the flywheel lock.

If the car has more than 100k miles, consider doing the front engine seals, especially the oil pump seal. Be sure to get a new sleeve for the oil pump. When I did mine, I got new sleeves for all (camshaft, both balance shafts and oil pump/crankshaft). My car has 148K on it.

well, the engine is in the car, so i don't need a flywheel lock if i just leave it in gear. i was planning on doing the front seal, as it is leaking a little bit. i talked to a mechanic about the oil pump sleeve, he said that was not needed. so i didn't get that. thanks for the info, i'll check it all out.

You still need a flywheel lock, at least I did on my car. I tried putting my car in gear and applying the brakes but for some reason it wouldn't work. If this is going to be your only time removing the pulley you can probably get by with a screw driver locking up the flywheel. If you are going to do this more than once though or if you lack another pair of hands to hold the screwdriver, I recommend getting the flywheel lock. Do a search for it, I believe there is a place where you can get it for around $30.
