Thread: ARGH rounded bolt - 300tdi PAS pump pulley

Normally, the bolts for the PSteer pulley come off with just the tension of the belt - but you've past that point.
Find one of these:



I found mine at super c wrap some years ago - whether or not they carry them now is unknown.

Generally the fan goes off first so you have room to move.

Then, use a six point ( impact type) socket. LR hardware is notorious for rounding using 12 point or even metrinch sockets. ( Especially the bellhousing nuts). You may have to give the ratchet a tap with a hammer to break the hold, but it should work.

If you do destroy the bolts getting them off - no big deal, they're only M8 x25mm (and some washers)

When you refit them they don't have to be super tight - and some anti seize might help in the future.

Put the belt back on, and you'll have to use a small cold chisel now they are rounded off. They aren't very hard IME and round easily. I use a ground down 10mm single hex 1/2" drive impact socket and one of these http://www.pbtusa.com/pdfs/70865I.pdf
too. 1 hit not 25 hits
When replacing the bolts watch the length carefully, as there isn't much room behind the flange for longer bolts.

Langy, thanks for that.
I've noted though that my PS pulley isn't grooved, as the smooth side of the belt goes over it. Does that differ from the norm?

I have a set of IRWIN bolt grip removers that will do the job but will destroy the bolts.

I think Langy was meaning the water pump pulley, which is grooved AND can cause the same issue with difficult bolt removals

That tool is great. I'll get me one of those.

agreed. I initially bought it to remove and tighten tdi crank bolts, which we do quite a bit, but it gets lots of other tasks too

worth its weight it has saved me many times, especially with honda engines that rotate anticlockwise and have a rh thread crank bolt so you can't undo them using the starter...

I'll order one tomorrow. Thanks for the advice.

Honda engines: I shudder at the thought.
