View Full Version : Stubborn Impeller wont come out, any ideas?

I cant get my impeller out. I lubed up the vanes with "personal lubricant" and spun the engine over to move it around good and the impellor still wont come out. I am using two paint can openers to try to pull the impeller out. It is being a pain and wont budge. Is there any tricks to this?? I sprayed some penetrating oil inside the impellor as I suspect that the spline shaft is corroded to the impellor, thus making it difficult. I figured If I let it sit there till nite time, rotate the engine so the impeller is 180 degrees to get coverage on both sides, and spray it again then let it sit until tomarrow morning and try it again. I am curious if anyone else has any other tricks to this...... I tried the search and really didnt find much.... :( Any help would be greatly appreciated. :)

Wow, never heard of the "paint can opener" trick failing. Bummer! I'd do what you're going to do: re-lube & try again. My guess is also corrosion onto the shaft. The good penetrants I've had luck with are PB Blaster and Kroil (that one is mail order only I think). I'd spray it good, tap it lightly with a hammer, put a vce grip really tightly on the vanes if you can, then give it a good yank! If that doesn't do it, I'd maybe remove the pylon to get better access, then maybe try a little heat from a torch. If all that fails, let the dealer try!
Good luck!

If all else fails, grab it with a pair of needle nose pliers and pull. Might not make for too good a spare afterwards, but it'll come out. Just be careful of your pump housing.

One trick I used, was 2 pair of big needle nose pliers 180 deg apart and if you tear a blade on the impeller just move to the next pair of blades, with plenty of WD40 sprayed into the hub and shaft. When you install the new one, use plenty good wheel bearing grease inside the hub of the impeller and on the impeller shaft. I use LUBRIMATIC Marine ANTI-CORROSION Wheel Bearing Grease and next time you change impellers the grease will still be in the hub and on the shaft. Good Luck!

UMP

can you possibly get a feeler gauge in between the impeller shaft & the impeller?

to get some of the corrosion out

I tried several times today before I posted here. I figured I would let that penetrating oil work.

THe visegrips is a good idea. I already have a spare impeller, so I am not worried about ruining this one thats in there now. I already have some anitsieze to put on the shaft for the new impeller. so this dont happen again. I will try again tomarrow morning. I will give it a tap with a hammer, carefully. What did you mean by being careful of the pump housing? can you hurt it? :confused:

Thanks for all the help!! :D

Yes, it's brass...therefore soft enough to dent or deform if you start getting too rambunctious with your various tools.

I bought an impeller from overtons two seasons ago and it came with a little tube of glycerine. Isn't that what astroglide is? :) Makes sense. Water based. Doesn't eat up the rubber impeller.

I have always used an allen wrench. Put the short end around and behind the impeller then pull with vice grips. You can also lightly tap the grips with a mallet or hammer. Rotate sides and check shaft for progress.

I've often used TMC No. 1's dualing needle nose method. Works like a charm when properly lubed (wire pulling lubricant works well). I always find that getting the new one in is a bigger pain.

Hoosier Bob
04-01-2006, 09:02 PM
What are you grabbing Easty, the rubber? Never tried it but may work. The allen key fits great (use the biggest that will fut) and pushes the impeller off. Always pops off but I may have never had a problematic impeller!

this is what the dairy industry has used for years for the rubber impellers of the transfer pumps, ice cream machines, etc... works great on o-rings also

Melting point 120 degrees? I would think the water would keep the impeller shaft cooler than that. this is what the dairy industry has used for years for the rubber impellers of the transfer pumps, ice cream machines, etc... works great on o-rings also

I'm just grabbing the rubber vanes. With enough lube, I can be gentle. No way for that not to sound bad. But I stay away from the pump housing this way and I have a stack of spare impellers, so if I mess one up, I don't worry about it much.

If everything else fails, there's always an "impeller puller". The special tool is available from outfites like SKIDIM, but if you talked nice to your dealer they may even let you borrow one for the afternoon? Haven't had one stubborn enough to need this hardcore of a method, but the impeller puller will definitely get it if nothing else does.

AWESOME Erk!! :headbang:

Well, I read all your posts, and I will try again tomarrow. I am thinking I will get it. I will try the double vise grip method. I will tap with a hammer too. I think I can get it. I will be sure to put antisieze on the new one for SURE!

Astroglide, I have used it, but not on the boat!!! :D

I have some of that petro gel too, we used to use that on our Ice cream machine at my parents grocery store years ago. its sterile, no germs for food use. I use it for o-rings on my jacuzzi filters and pumps. works like a charm for that. doesnt harm the rubber at all.

Anyone have any other ideas, I am still listening!! :wavey:

Thanks again!!

After wrestling with mine, and the limited space in the v-drive, I bought a puller and have never regretted it. As for installing, I always found it easy if you lubricate it and turn it with the palm of your hand while pushing hard to insert it. The vanes will fold down while rotating and it will slip right in.

I got his pair of needle nose vise grips, and when I came home tonite, I grabbed my pair and got a good grip on the impeller gave a strong pull and..... nothing... so I tried again, one helluva strong pull, and out pops the impeller!! :toast: SO I am gonna put the new impeller in tomarrow, I want to clean the housing out with soap and water to make sure I get out any traces of pentrating oil so it dont harm the new impellor. I will install the new one first thing in the morning, and then the next project, The new engine cover insulation!!!! :dance:

Good deal. Hope you marked the position of the impeller or at least remember where the little tick mark was.

As for the engine box insulation, the best thing I did with that mod was let somebody else cut that thing up and install it. The old stuff peeled out pretty easy. The old adhesive took some scrubbing to get out. By the time it came to cutting patterns, I'd had enough.

Check out the "hot to" on www.wakesiderides.com. It's very good and full of pictures.

The side pointing out should say Johnson 812 on it. Just make sure the notch on the new on is in the same position as was the old one. You sort of have to manipulate the vanes a bit to get the new on in there. Lube her up good UMP.

UMP, if the bomb didn't go off at your house, then if it is installed improperly your propshaft key will be 180 deg. off, which will cause you steering wheel to pull to the reverse side of the rear view mirror! :steering:

You can solve that problem if you use the notch removal tool that comes with the impeller puller. After properly conducting a notchetomy, it doesn't matter which way the impeller is installed.

A bit of a thread jack but impeller related. Last fall I put in a Globe impeller (blue ones that are suppose to be able to run dry for 15 minutes). Although someone posted they had problems at low idle, mine ran fine with no problems the two times I took it out. This morning, I put the boat in at the ramp for the first time and no cooling. Pulled the Globe out and put a Johnson impeller in and headed out on the lake. Nothing but the original from now on...and having a spare impeller and puller made it a 15 minute job. I did notice the notch for the first time but have no idea what it's for.

Was the boat stored all winter? If so, it was probably a good thing to change the impellar anyways.

West Marine sells the impeller pullers....I bought one and it makes taking them out very easy. I bought it because the previous owner of my boat only changed the impeller when it went bad...probably had been 3-4 years since last changed when I tried pulling it out...

Someone else had posted a while back that they screw two drywall screws into the rubber, close to the hub and then pull on those with pliers or vice grips.....

The smaller Jabsco is what I had and it worked great. I had to unscrew the center piece to get it to work in my V-drive as there wasn't room because of the rear transom. So I just pulled on the cross bar once it was in place and out came the impeller.
