timing belt procedure

[MitsuBoost]

i have all the other belts removed and im ready to remove the timing belt, but as i referred to the service manual, it says to remove the camshaft and oil pump sprockets... is this really necessary? i dont see why the timing belt and the BS belt couldnt just be removed by loosening the tensioners and idler pulleys. This is my 1st time doing this on a DSM but ive done several timing belt jobs on VWs and Nissans so im pretty familiar with the procedure..

For the timing belt you don't need to remove any sprockets. For the Balance Shaft belt you need to remove the CRANKSHAFT Sprocket. At least on my 92 TSI I had to. I would suggest getting a new Timing belt tensioner as thats what I did since mine has 91k on it. Actually I replaced ALL the pulleys. I also removed my oil pump sprocket, big mistake, I totally didn't know what I was doing so I rotated the engine since I had the cylinder head off and I forgot where the oil pump sprocket went or I mean to say how it was last aligned.

Read this a few times and then tackle the job:

Oops my bad you have a 97...look on VFAQ for the 2G guide and it may be a little different from mine as I have a 1G. The VFAQ site has lots of helpful information and how to's.

You do not need to remove anything from the crankshaft.

If you are patient, you can work the BS belt around the blades for the crank sensor.

Bring the belt out using the notches cut into the crank sensor blade. You can install the new one using the same method.

job well done!! I was real close to paying a shop to do it only cuz ive been so lazy to get under my car but when i was quoted $350 i said "time to roll out the tool box again I now know what you are referring to when you say "blades" Thanks for the tips. Oh and btw, i didnt have to remove any sprockets but i wonder why the factory manual says to remove the cam and oil sprockets

The factory manual for some reason makes the assumption that when you replace the timing belt you will be replacing the BS belts. To do that you have to remove the sprockets. I just did my timing belt and had to improvise on some of the steps otherwise i would have had to do alot more work then was really needed.

Mostly because at the time when you need to replace your timing belt, you should be replacing your balance shaft belt as well. If it goes, there goes your new timing belt too, after all.

No problem and no idea. Mitsubishi must prefer the hard way, don't they know we are lazy Americans?
