Timing Belt

Hi all. Finally I am done with my timing belt change job, last week. I did not captured the step-by-step procedures on how to change the timing belt, there's a lot of websites offerings the guide. Herewith I recommend this website for your reading if you wish to DIY your timing belt change. The Youtube videos attached on last post should be more than enough as your reference.

In addition, let me share some lessons learnt from this exercise;

1) You may use whatever technique to jam-up the crankshaft, even better if you have the special tool. Please prepare a bar that can be linked to your socket wrench when unbolt the 24mm bolt. It is VERY TIGHT, and please don't over burden yourself, its bad for your back.

2) Before unbolt anything, have the sprocket and shafts set to TDC, and ensure they are all meet the marks. Don't turn anything if you unbolt even the sprocket until you re-install the timing belt, this ensure no timing adjustment potentially will occur. In my case I took this opportunity to unbolt each sprocket, clean them up and ensure all oil seals in good shape.

3) Note that there are 2 type of timing belt for 940, pre 92 model and post 93 model. Look carefully on part number, they won't fit each other, even the tooth pattern is different.

the tooth design is different!

the old belt marking ('91 and '92 models)


the new (wrongly delivered) belt marking ('93 and above models)

Other than that, I think had been discussed and elaborated in other pages as well!! By the way, had successfully installed my first DIY timing belt! Alhamdulillah.

Good Day!
