thanks guys, although don't think my face will be very soft after a couple of hours struggling with the starboard engine impeller which is conveneiently mounted on the side of the engine right next to the fuel tank. Thanks Volvo!

Depending on the type of pump, Volvo do a range of very simple impeller extractors which only cost around £3-£4 (cheap for Volvo).

Phil,
the only puller I know of is the Jabsco one which is about £35? Even with this I've got to cut the T bar off and replace with a nut as there isn't room to rotate it when in situ. Do you have any details of the Volvo one? It's a big pump, 3.75" diameter across the vanes and about 2.5" across the hub

Re: Impeller putting back!!!!
Was shown this trick by my local MAN engineer....carefully put a couple of wide (need to be wide so they don't cut the impeller vanes) diameter cable ties around the impeller and tighten (the right way!!!!).
Slip in a bit cut the first tie, slip in some more, cut and so on depending how wide your impeller is.

I got one from Poole Marine Services at Southampton Boat Show.

It's not much more than a nut and bolt- much smaller than the Jabsco - but they are supplied for specific pumps. Suggest you call them for details.

thanks for that- had heard about using ties and have bought some that seem to be suitable based on your description. I have also had to make up a centre shaft to stop the impeller twisting when putting the ties on which was just a long bolt clamped in a vice with the bolt head that fits the splines on the impeller hub.

Hi Nick,
Two screw drivers either side of the impellor and gently lever out, of course a puller is best but if it won't fit try the screwdrivers.
For getting it back in, if you already have a stock of it use KY jelly! if not then as already said fairy is fine. The best tool I have ever found to squeeze the vanes together so that the impellor can be inserted into the pump body is a piston ring tool. It can be obtained in most car spares shops for just a few quid and works really well. Use plenty of KY/Fairy on the inside of the tool before tightening the tool onto the impellor.
Good luck
Barry

yes, but they only work on the latest volvo impellers that are modified for the tool. When I asked this a few weeks ago, another suggestion was instead of screwdrivers use toothbrushes, as the plastic handles wont damage the pump housing.
