Impeller Puller

Rogershaw said:
If you buy an internal caliper and bend the legs then the opposite direction this would then grip the rubber to allow the removal of an impeller.

A pair of engineering dividers could also be modified to do the same job

They would grip the impeller, but have no means of pressing the impeller out, which is the advantage of the impeller removal tools linked above.
 
A mate needed one so I spent a day in the workshop and made one out of bits of stainless. I also made him a split case internal bearing slide hammer / puller.
As i have the gear and the time it was not an issue.

My question would be why are your impellers getting shredded in such a short time?
Mine is as old as the boat, 37 years, is a jabsco and still going strong .

Bad luck? I have had damaged impellers perhaps 3 times in 12 years.
As suggested not really necessary to change every year so I will pull the one in situ and have a good look at it. If it is ok back it goes with plenty of impeller grease.
Thanks,

Could someone let me know what grease to use on Jabsco impellers please.
Is silicone grease any good?

Thanks

In my experience, whatever you have will do. Silicone, normal grease, vasaline will all aid insertion and lubricate the impeller for the first few seconds until the water starts flowing, after which the water is the lubricant. Impellers are usually made from Nitrile rubber which has good resistance to oil and grease.

Two sharpened toothbrush handles, I've been told. Never had the problem, 135hp Ford, but bigger pumps are easier. Must say, I would get many thousands of hours from one, like 3000 at least. I had a dry exhaust, so the cooling water outlet showed any diminution in flow instantly. Porthleven can be weedy after bad weather and some days I had to clear the seacock twice on the way out. Maybe a good inlet filter saves impeller damage? Mine was rolled up oyster bag plastic mesh.

And at the risk of telling Grannie(or Grandpa....etc. don' t forget the trick of using a tie wrap to compress the vanes and in the right direction for insertion.

I had a pump on my bench once, having changed its bearings and seals. After tiring of the tie wrap slipping off at the last moment I just stuffed the impeller in, any old how. I then replaced the cover and using grips gave the shaft a couple of rotations. Removing the cover revealed that all the vanes had assumed their correct orientation. Ever since then I’ve continued to just push all the vanes in without worrying and never had a problem.

I use an oil filter removal tool to insert my impeller, it is a large impeller though. As mikegunn says they sort themselves out once inserted.
