Re: [DML] Re: Water pump pulley. Or, how do I get the @^#$^% thingoff.

You're pressing on the pulley, not on the shaft. The pulley is made in 
two parts, the pressed flimsy outer bit and a (very) solid tube down the 
middle. You need to press the shaft out from inside this tube. You're 
probably pressing on the whole thing which is why I always use a bolt, 
or a well aligned socket as Dave says. If you need to just start it, 
there's a short M10 bolt easily accessible to the left of your engine 
holding the left exhaust bracket to the engine block with a 17mm head. 
Use that partially threaded into the shaft to get it started, then 
you'll know where you are.

As we always fit OEM pumps which include the back plate, I install the 
pulleys using a well greased bolt, nut and several washers.

I have pressed one pulley off that took about 12 tons to crack and when 
it finally came off, was a loose fit on the new pump and had to be 
replaced. Bizarre!
