Timing Belt

[chrisg]

In answer to your question, no you don't actually need the timing belt tensioner tool to set the tension. However if you've never done it before you'll have no reference point on how tight it should be.

On a separate note you WILL need a flywheel lock and a deep 24mm socket to get the crank pulley off.


Whilst ur doing the cam belt you should also do the balance belt and pas n alternators too.

Happy to talk it through with you on the phone - I also have all the relevant tools you'll need.....

I didn't use a flywheel lock when I changed my belts, not saying that would be the case every time but you could try first before buying the tool.

From my experience, if you want to change the belts, (and its definitely a good idea after 10 years) and you want to do it properly and re-torque correctly without damaging pulleys with chain locks or cutting the knuckles off yourself, then use the lock and follow the guides carefully as Chrisg suggests.

If you want to chance it, do that but there are risks which are significant.

The existing tension on the old belt is an indication of the correct adjustment. If you have a reasonable touch you can get calibrated that way. If it sounds like a washing machine on spin cycle, its too tight

Its not rocket science []

Good luck

[] The cambelt can be removed/replaced without removing the pulleys, the crank lock has to be used if the waterpump or front seals are being replaced and that's because the pulley has to come off to remove the rear belt cover.

Werd.


I just finished removing all the belts and rollers from White944 without removing the crank pulley. Couldn't believe what a doddle it was compared to most modern cars.

Can't put it back today as one of my new rollers is wrong[:-]

I've got the relevant tools but no tensioner gauge. But my car is a late car so the tension is easier to set than on an early car. i did my own belts and water pump etc then took it to the OPCF for a tension check. If your not sure then take it to a specialist or Porsche. Be careful though as one of the local specialist in Glasgow really likes to charge for other things he finds without letting you know first. i know a few people who have got big surprises going there.Obviously I would never say who on the forum.

If you're worried, you can borrow the tensioning tool for the cost of postage as a Club member. [8|]

Thanks to everyone for responding. I got a quote from a independent Porsche specialist in Glasgow and he said £300 upwards as he wouldn't know if it needed any rollers until the belt was off which is fair enough. I may take it there if finances permit as i know he will do it right otherwise borrowing the tensioning tool could be a good option for peace of mind. Until then I guess I shall be driving it sparingly with the fingers crossed.
On the bright side at least the flywheel locking tool can be bought for around £30.
