Does anyone know where I can get a tool to remove a Jabsco 2.5" impeller, without spending £40 plus on Jabsco's own tool? I understand that Volvo make a bolt-like tool that screws into the impeller, but I can't find a stockist.
 
Screw drivers, as said above, they normally don't do any damage and if they did, I rarely put the old one back in anyway, else why take it out?

H, I remove mine each winter so that it dosent get a memory from being in the same position for months. I agree however that replacement is probably the better answer to this but like you I'm tight........ or should that be like Kwacker I'm tight. :)

PS How are you doing, are you back home yet or are you still giving the nursing staff a hard time.

I think you are confusing Jabsco and Sherwood pullers. Jabsco make the nicely engineered puller which at £40 is well worth the money.

The Sherwood puller is a 5/8 UNF (I think) bolt with a T bar though it and jam nut to fit Sherwood 17XX and above pump, costs about a tenner, however I do not think any Jabsco impellers are threaded.

don't use screw drivers!!!

What ever you do don't use the screw drivers - very easy to damage the soft brass pump body. also at that size it takes quite a lot of force to get the impeller out. Jabsco tool is £40 but you will have it for years. New cooling pump £500+ its a no-brainer. Take care with the brass screws that hold the cover on too - when you refit the cover they only need to be a bit more than hand tight. I changed mine to M5 X 8mm stainless steel cap head bolts that tighten with an allen key. much easier if your pump is difficult to access and you can "feel" the torque better. Keyparts (on the internet) sometimes have a small puller for Volvo 63P engines as its a pig to get at. I think this is @ £10 if its suitable.

When you reinstall the new one,lots of grease to aid slipperyness until water can get to pump and lubicate impellor vanes.Keep old unit for emergency use.

Yep but thats just for the soft gits, that stop boating every winter. or soft boats that melt if they dont come out every winter.:D

Yep, back home now, unfortunatly. Getting grief from Debs. Hospital was quite entertaining.
 
I've had my jabsco impellor puller so long I can't remember what it cost. Not much if converted into a fee per year, I'm sure. I also think the speedseal covers are a godsend; no more fiddling around searching for stray bits.

After struggling with screwdrivers for 5 years and knocking chunks of knuckles off I decided I needed a puller, £40 divided over several years is cheap enough and when you finish with it you will get £30 back on ebay anyway !

I made a puller/slide hammer attachment using 2 VP DP anode ring screws and 2x 2 inch metal strip, I would post the details but the forum will enjoy poking fun at me too much as its a bit PBO ish , I could send it to Wiggo for approval :D
 
Try washing up liquid, better for the impellor, not too bad for the water.

Silicone grease is the correct lube for impellers, thats what most come with now in the litte sachet.
I allways put some grease in between the vanes and then crank angine a few turns which spreads the grease between the vanes and the pump body then removal is a lot easier, the pullers are good but the sherwood idea is much better, just remembetr when removing sherwood impellers from the pumps with the plastic liner to make sure you secure the liner first as it will most probrably break if it comes out with impeller.
 
Do as I did, for the next 10 years struggle with screwdrivers and tape then buy the proper tool!!!

how did you get a tool to fit on an S37? not possible on mine. Not enough clearance in front of the engines.

I have to take the outlet pipe off and hammer a screwdriver into the side of the impeller. Lever sideways, I can move it the width of the hose. Remove screwdriver hammer in again and repeat.

Reuse of impeller obviously not possible but I never take the boat out of service anyway so I'm not going to worry about the memory thing - even used her this week.
 
Removal tools

Some impellers used by yammer and Volvo are threaded to allow the use of a simple removal tool consisting of a stewed bush that screws into the impeller and has setscrew that jacks out the impeller

Only problem is that there are several sizes of impeller specific tools and you only know if you have a suitable impeller when you inspect it and find the thread

When they work they are great

I changed the impellors on an s37 a few months back and there was plenty of room in front of engines to get them out. (KAD43's)
 
Thanks for all the advice, guys. I think I'll bite the bullet and buy the Jabsco tool. I plan on keeping the boat for a few years, so it's probably worth the inveatment.
