Hi Guys,

Had the 964 out last night and after a 30 min perfectly fine drive, I put my foot down and just had a mass of hesitation, pinking, rasp and a gradual pick up in speed until it burst into life and off it went.. Backed off, tried again and it wasn't as bad but still had a miss, revving the car in neutral, no problem, revs fine. Got home and I could hear a miss but it seemed to clear itself, so it is very much intermittent.

The plugs are new, they proper spec Beru ones. The leads are not too old. I don't drive the car much, had it out for a meet last time and it performed faultlessly.

The caps and the rotors appeared clean the last time they were off when I did my valve clearances(less than 200 miles ago) but they did have some mild wear on some of the tips, so I am going to change those as part of a refresh to cure this prob. Whilst I am doing that, it makes sense to change the belt in the dual disti setup as I have no record of that being changed.

So my question, has anyone gone about swapping the belt themselves? Is it a worthwhile DIY or best to ship it off to a specialist for a full service? (If anyone does that).

Thanks
Mark

Have a look here

A member here Diddi seems to specialise in this and a number of people on here have used him for both parts and full refurb service.

Perfect, thanks for that, that's got me on the right track!

I am going to pull mine off and see what is needed, then contact diddi to source the bearing kit, should change all of them while there.

Parts list isn't huge and other than a link on ebay.de, no idea where to get the bearings.

Belt CONTI CT-1032
3 x INA 7201 (32x10x12,45mm)
1 x INA NX12
Pin

Someone on ebay.de selling the kit for 180 euro

Just pulled mine apart, belt had been done before and only just starting to show some age.

2 of the 7201 bearings need replacing as I can wobble the centre slightly, so I need to locate some of those.

How are they best removed?
