Fuel Pump Pulley Nut/bolt

Post by Titan1995 » Thu Sep 20, 2012 2:12 pm

2.5TD Auto...in the process of removing my fuel pump to replace the seals.

I am about to undo the main fuel pump pulley nut.

Am I right in assuming that this nut undoes in the normal way i.e. anti clockwise?

I ask this as the nut is particularly tight. I have wedged an old screwdriver between the flywheel teeth and the bell housing to lock the engine. Even with a fairly long breaker bar I am not freeing off the nut. I do not want exert any more pressure if the nut in fact undoes clockwise.

I wedged a breaker bar with a 38mm socket against the propshaft. 2ft long breaker bar on the pulley nut and off it came.
Pump is not sitting on the bench.

Decision time now....do I get the pump reconditioned or just replace the leaking seals.

All was working well prior to the leak.

Huge cost difference though. £20 ish for a seal kit of £500 for the pump to be refurbished.

Having said that...the pump has been doing its stuff for seventeen years so might need some TLC.



Answers on a post card or stuck down envelope please.

yep undoes normal anti-clockwise, i personally just put 19mm on the end of a breaker, put it in place, take up the bit of slack, then snatch it, never had 1 that hasnt undone like that yet? either that or get a BIG socket on the crank nut?
