Thread: 300TDI WATER PUMP REPLACEMENT - PULLEY REMOVAL TIPS??? HELP

Sidelined until I can get these off to access water pump bolts.

Any Help Appreciated!!!!!

Cheers guys

Which engine?

SORRY 300TDI CHEERS

if you have an impact driver, I'd try this first.
If you tried this, then a few other things you could try:

make a small bar lever type tool to go over and around two of the bolt heads, which gives you leverage to hold the pulley better and undo each one in turn.

if you have a blow torch, remove belt and give them a small amount of heat.

sometimes a few taps on the heads of the bolts can loosen them a teeny bit too.

If it is the pulley pictured, have you tried an allen key in the centre?

Hi,
I've had luck by getting some thin rope, tying off one end, and wrapping several turns around the pulley so the rope tightens as the pulley turns, pull hard on the free end as you loosen the bolts. Like a capstan winch in reverse.

Have have aso tightened a ratchet strap around the pulley, tying off the end and loosened the pulley

I would also get yourself a 6 point 10mm socket (I use an impact socket) grind the chamfer off.
This will give you the best grip on your damaged bolt heads.

They're not big enough to be that tight. They'll be loctited. As suggested impact gun, or heat, or both. My little impact gets in there.

Try putting a rag between the pulley and the belt so it tries to pull the rag in as you turn the bolts
