An hour? How many have you done in an hour?It should take you about an hour as long as you have the special tools to lock the camshaft and the diesel pump.
Look on the clutch bellhousing for a rubber plug. Remove this plug and rotate the engine round to the scribed mark you'll see on the flywheel. This sets your datum.
If you haven't got the locking tools I can sell you a set cheaply.
This engine was one of my designs from around 25 years ago. Book time is around 1 hour.An hour? How many have you done in an hour?
If he did it in 4 he'd have done well.
Your memory is not all it should be, old chap.The screws are normal thread, they are the typical poor quality allen screws that VW fit (not deep enough).
Are you using an allen socket or just allen keys, you need the best allen socket you can get for these.Try a torx bit if you have one, but only if it fits very tight.
I have undone these using a stud extractor that fits on the outside of the bolt.
Unfortunately on that engine this a very common problem.
One thing to check before you fit the new belt is to take off the water pump and see if it has a plastic impeller, if it does replace it with one that has a metal impeller, why they fitted a plastic impeller lord only knows.
A good Allen head socket should move them.Hello everyone, I am now 2 hours into the job and I am stuck, as I cannot get the V belt pulley off!
The 4 allen screws holding the pulley in place are seized, and are getting damaged. (unless they are reverse thread??).
I tried the ususal WD40 and the tapping with a hammer whilst applying force, but none of them move.
Never heard anyone recommend using a Torx bit in an Allen head before. That truly is shameful
Well, that's the problem then.Hi there,
I was using a Halfords 3/4 allen socket, however the fit didn't seem right from the start.
An extremely good answer from a very naughty boy.Why would rescuing someone from a disaster be shameful, if the allen screws have spread open (which they nearly always do if they haven't been removed before and rusted up)?
The splines of the torx bit dig into the corners of the hexagon and can give good grip, enough to undo the bolt.
Some of us have to use initiative at the sharp end of repairing motor vehicles, if that's shameful, then guilty as charged.

Glad you're not a surgeon.
Mind you, they can bury their mistakes.
Like car-man I have nearly 40years in the motor trade, and I was not kidding when I said hammer and chisel, many a time other mechanics in my garage came to me to remove nuts/bolts, and very often the hammer and chisel were the only tools to do the job.The thought of hammer and chisel on pulleys, be they timing or crankshaft pulleys, only leads to disaster and real expense. We'll see what develops.
