Uk Rallye Timing Belt

Recommended Posts

custard-rallye

im fiting a new timing belt to my 205 this weekend, does anybody have any tips as i just started my apprentiship as a mechanic.

 

i had a look on auto data and it looked fairly easy.

 

does anything need to be moved or any help would be great.

It is dead easy. You only need to take off the 3 parts of the timing belt cover. The top and middle section are held on by a few M6 bolts and nothing else. From memory you only need to take off the alternator belt and pully to get off the lower timing belt cover. The belt and tensioner are then fully exposed and easy to work on.

 

I use a cut down 6mm drill bit (about 40mm long) to lock the flywheel and a 10mm bit to lock the cam pully.

 

You'll need a 6mm square sump plug spanner/socket for the hole in the tensioner. Mine is a Draper one a cost a couple of quid.

 

Definitely replace the tensioner as it often gives out before the belts do. Not replacing it is a false economy.

 

Don't forget to take out whatever you use to lock the flywhel before you try and turn the engine over on the starter! Done that before and had myself stumped for about 5mins :)

To lock the bottom end an M6x25mm bolt works perfectly and an M10x25mm fits the cam pulley as mentioned.

 

It's actually an 8mm square key for the tensioner, not a 6mm

Just remember to tension it properly and make sure it is centred on the tensioner.

 

Some people use the twist 45 degrees method.

 

I personally use a fishing weight for 1.5kg tension (as described in the haynes manual) since its very easy to get this wrong and end up with a wizzing sound

i did the timing belt yesterday everything was fine until i started it today and it started making that wizzing sound what causes it to do that to much tension or not enough??

If it is a whining noise it is probably too tight. A whizzing could be that one of the covers is rubbing on the belt, so check that also.
