well i no longer have a toothed drive belt as it left me on the motorway friday night at 11pm >:( got recovered eventually after nearly freezing to death.
The car had been sounding rough on idle for a few days and stupidly i wanted to wait till the weekend to investigate,should have retired the car but just needed to get places. It went silent after 1.5k and i dismissed the belt being the issue.
Looking at the pulleys now they looked like they have been abbraised as they are quite shinney in places, so i dont know whether a stone or something had got caught it the belt? sounds silly.
So im going to be ordering a new one, would this be corerect?

How much play should be left in the belt once fitted?
sorry for the Q's but im new to all this
thanks for any help,
John

If i'm not mistaken, thats the charger timing belt on Jabba site. If that went on yours, the charger would have grenaded!
I guess you mean toothed pulley belt?
-
Ah sorry Nick yes thats the one! cant seem to find them online. but its defo the external belt linking the alternator

thanks nick, problem solved
-
how worn are your toothed pullies? Have you been using the proper belt on them or just a timing belt? That one we sell is a proper one.
-
they arnt that bad just a little shinny in places tbh just had another look. im guessing that it was the correct belt in the 1st place
-
If you have a stone fly up and hit it, then it could have caused it to break.

I'm on my original belt of +20K miles, an I run it with plenty of play/give, no were near as tight as either my cambelt or the OEM V-belts, keeping these belts slack will also vastly reduces bearing wear too, I can get a 180 degree twist without too much trouble between the charger and crank pulley with my belt. I have got some evidence of bits of forign body(grit/stones) getting caught between the pulley and belt, but nothing that has caused a failure.
-
right ok cheers for that info, so best to leave a slight bit of play then
-
I used to tighten mine up the same tightness as a cambelt, so you could only twist it 90deg between the bottom pulley and the charger pulley, lasted years like that. In fact I never had a belt snap, I replaced it once just because the old one was old.
-
Very strangely.....I read this thread about 4pm today. Then I popped out to do some work and on the way home my belt snapped! Gutted. So gotta order 2 asap as its my daily driver!
-
wow that spookey, i dont feel so alone now! i hate it when the daily is out of action
-
I'd advise anyone with toothed belts to carry a spare in the boot. I did even though I never needed it. It's not like you can get the correct ones in any halfords like you can with a fan belt.
-
Yeah I'm buying 2 this time so I got a spare. Messaged pete so just awaiting a reply now...

Big thanks to Raw (Andy) on here for sending the new belt out so fast. Well the cars running again but not after a bit of a game to get it on. id sourced an allen key for the supercharger mount and lowered it down, slipped the belt on and pulled the charger back up and secured it all with the correct amount of play. Fired it up and the belt was slack again and a few more goes at lifting the charger and lighten soon cure that ::). But im unconfident with my crank pully, it has no raised sides like the others so nothing to prevent it from moving about and rubbing against the engine plastics. anybody else find this? maybe its just one dodgy pully or is that normal?
Anyway had my G smiles back today! Yay! ;D
-
mine did it, it turned out to be the 19mm bolt located just below the pully on the supercharger (its propa shagged), tho i had to remove the charger to tap out the hole again and i also used a new bolt as the old one was fucked.
mine's fine now and hasn't moved at all,
i'd tap the holes out again if your'e getting movement, think the threads are M12
cheers Tom

UI don't think any of the bottom pullies on the toothed belt kits had flanges on the sides. On the toothed belt kit I used to have (which was one of the very first batch sold by PSD) the alternator & charger pullies both had flanges on.
-
yeah mine has the side pieces on the charger and alternator pullies but nothing on the crank pulley
-
ah thats a relief then

Me and my big mouth 30k, belt started loosing teeth last night(was sounding rather rough), mangaed the 50mile round trip to work and snapped about 3 miles from the house while returning from the motorfactors! Cheers to Sauce(my mate) who recoverd me with his golf
-
but it lasted 30k though? I dont think that's an issue
-
Always carry a spare belt with me, just incase and a few tools although it has only ever gone on me once so far and it did go for a fair few miles before anything happened to be honest.
The belts from pete seem to do the trick though ;)

Your right, not an issue, just a temporary inconvience really, I think it did rather well
