Thread: Repalcing a 300tdi injector pump - auto 94

If you dont want to pull off the timing cover, you will need this:

But to be honest, unless you know the condition of the '94 belt, idler and tensioner I would be pulling the cover off and giving it the once over. The clearest instructions for 300tdi T-Belt change out can be found on the UK Difflock website.

But, to remove the viscous fan you need a 32mm flat spanner its reverse threaded.

Thanks for the reply.

I had read that thread and I am confused as to what you do with the plate. Do I undo the 3 bolts that hold the existing plate on, then screw 3 new bolts through my new plate and then undo the IP from the other side? Do I leave the big central bolt where it is?

As regards the viscous fan, I presumed there was a nut at the front, but I can't see a nut, just a funny cover that doesn't seem to come off.

Just a little more help please...

Thanks, Erik

So the nut on the viscous fan is the one in between it and the pully??? I had thought it would naturally be on the outside, between it and the radiator...

Correct. The nut is hard attached to the fan, and it screws onto the pulley.

I gather you can make up some sort of plate and do it without redoing the timing, but I am having trouble understanding how.

I can get TDC with an injector removed and a bit of wire down into the engine. This also coincides with getting teh injector pump locking pin in, but I can't find a corresponding locking thingo on the crown wheek, starter rinng thingo. There is a bolt hole at the bottom of it, but I can't see or feel anything that feels like a slot that would hold a locking pin.

Do I take the whole timing belt cover off to be sure. In which case, how do i get the fan off? (Not the bolt, but the viscous bit, so that I can get access to the bolt). Or else what do I screw things into on teh injector pump plate that will hold it all in place while I remove it and how do I remove it if a plate covers everything????

Erik

The flywheel locking pin hole on an Auto equipped 300TDi is behind the small tin plate cover on the vertical surface of the flywheel housing off set to passenger side, there are 2 bolts holding the plate on. The larger of these 2 bolts , once removed is the place that the Flywheel lock is screwed into, so the locating hole on the flywheel is on the forward facing side of the flywheel and not on the bottom edge as in the Manual gearbox equipped 300TDi., Regards Frank.

Just a caution BTW, if you have to take the front cover off - and to do that you will have to remove the harmonic balancer - DO NOT rely on the above mentioned locking pin to hold the crankshaft while you undo the crank bolt which retains the harmonic balancer - you will in all probability sheer that "locking" pin.

And the alloy housing isn't strong enough at that point, it can twist.
How do I know? I choose to remain silent on the grounds that I might incriminate myself.

See if you can borrow a tool that holds the front pulley instead.
Whereabouts do you live?

Yes, don't touch that.
