Cambelt change

Post by aibast » Mon May 21, 2007 7:07 am

For this job you better get a proper toolkit. Cos in here you need different things. Get a new cambelt, alighment wheel, and tensioner. If you need to change the alternator and aircon/powersteering belt then get these things to.
Image

Firs you need to remove the aircon/powersteering belt.
Image

For that remove the top powersteering pump pulley cover
Image

Next loosen the frontright wheel polts and lift the car up. Secure it with jackstands and as a safety feature, remove the wheel and but it under the car. Just in case the jackstand fails.
Image

Now remove the dirt/tust cover from the wheelwell to access the cranshaft pulley. Remove the aircon and power steering belt.
Image

Take out the polt just under the engine numberplate
Image

Rotate the engine using a wrench and a 19mm socket. So the timingmark on the cambelt cover lines up. It can be seen as a hole on top or the cambelt cover that has a point in the middle. Next try to but 7 or 7,5 mm drippbit in to the hole from the side of the engine. It should go right in and lock the cranshaft. If it doesn't have your friend turn the engine slow and easy that thing in to place. To turn the engone easyer remove sparkplugs.
Image

Now mark the camtiming mark on the engine side cover so that you can see it from the cambelt side. It is very important. I did this mistake not marking it and had to do some extra work because of that. Now remove the cambelt cover.
Image

Remove the cam belt. Then the pulleys that don't have teeth (there are 2, the tentsioner and an alighment wheel ) and replace with the new. Removal is some what a difficult, but can be done. Its a tricky job, cos there isn't a lot of space. I suggest removing the rear polt of the engine dampner and turning it up and away form your way and removing the powerteering oil reservar from its place. Just to give you more space.
Image

Then but in the new wheels (2 of them)But on a new cambelt. First but on the bottom, then the alighment wheel, after that the cam. Now comes to play the mark you did on the cambelt cover. Cos you need to get the cambelt pulley to the right place. But to get on the blet nice and tight. Turn the cambelt pulley 1 tooth forward. But the cambelt on to the pulley and turn it back so its tight and doesn't move back any more (remember you locked the carnshaft to place with the drillbit). It now scould line up the mark on the campulley and the mark on the cambelt cover. This also gives you enough slack in the belt to but in the tensioner. But the locknut on it but tont tighten it full. Only that much so it can still move on the bolt. To tighten up the tensioner. But it in its place. Get a strong and long screwdriver and use it as a lever on the rear side on the tensioner. Get the cambelt nice and tight (if you press on it it shouldn't move more than a few mm. Let your friend tighten the locknut full. PS. After a couple of hundred miles, retighten the tensioner as the cambelt streches a little when new. Sorry for not having pics of this stage. my hands where full :)
Image

Now the order is reversed to but things back together. And do but a new copper washer on the polt you removed under the engine number belt.

I meant to post here a while ago, when I changed my belt. Brill guide! Was my second cambelt change & first on my own (the other being on my 240 much easier & with an expert to hand).
Great post which helped me loads. :hopping:

One little remark,

Maybe I missed it, but to use a screwdriver to adjust the tensioner ?
On the rearside of the timing belt cover (the side that points at the passenger) there is a hole with thread, I think M8 or M10.
By screwing a M8 or M10 bolt in, you adjust the tension, and when good, locking the nut and get that tensioning bolt out.

Yes but if the car is righthand drive the brake master cylinder makes using a bolt virtually impossible !

Large screwdriver seems the only option for RHD...unless anyone else knows a better method...

The tensioner set screw hole is M6 by the way. The bolt you use will need to have about 30mm of thread. If you do not have a suitable bolt then the auxillary belt tension set screw found by tyhe alternator does nicely :wink:
