damn impeller!!!

[chrisdoc0608]

i have spent the last hour trying to get my impeller off. i dont have the spline tool, but i used an extra midshaft and and put the splines in it, and used a pipe wrench on the midshaft and a pipe wrench on the impeller, i put heat on it, penatrating oil, and had me and another guy stand on each wrench and it wouldnt budge.... what else can i try. i would like to get my new impeller on b4 i ride tomarrow.

Heat the hub of the impeller, ice the shaft.

Reverse threads, make sure you are turning the prop clockwise

Lots of heat. I think they come with locktite from the factory. Need to get it hot enough to melt the locktite or any of that chalky white corrosion. If that fails just use a cutting wheel to cut it off.

seriously, ive done this. been there, hated it, gave up, broke a pump mount ear... gave up AGAIN.

get a BENCH mounted VICE

put the shaft holder tool in the vice, slide the shaft in, and put the impeller spline tool in the inpeller, and get on it with a BIG wrench ( pipe or other) and put your weight on it.

the driveshaft will twist until it gives.

I have never had to use heat or penetrating oil, or anything like that, but I had ALOT of problems until I got a bench mounted vice to hold it all via the driveshaft spline tool.

Heat is your friend and just make sure your turing it clockwise, its a left handed thread. (been there done that before):banghead:

we ended up taking one of mine to a local jetski shop, they got it off in like 5 minutes. it was a last resort after we broke our vice mounted bench.

 

[Mouthfulloflake]

if they got it off in 5 minutes, can we assume they simply had a bigger/better vice?

haha

Be sure and use anti seize when you install the new impeller, it will make it a lote easier to get off the next time. I have had one that was tough to take off before, used a lot of heat and a big pipe wrench, and it finally came off. Check the runout of the drive shaft after you get the old one off, and straighten it if is out of tolerance.

 

[chrisdoc0608]

i have no clue how to check the runout of the drive shaft or how to straighten it. im abt to take it to a shop and see if they can get it off

The bench mounted vice is definitely helpful. I had a huge beefy bench mounted vice and snapped it trying to press a u joint out. Almost broke my sternum when it snapped. My point is that without a vice i put a big box end wrench on teh spline tool and then used 2 c clamps and clamped it down to the bench. Worked about the same.

I think you said you didnt have a spline tool. I would suggest getting one or you will probably maul the drive shaft up pretty bad.

 

[WaveDemon]

mouth is right. one of the times I changed an impeller I didn't have access to a bench so we put a wrench on the spline end and drove a truck over the wrench. then we put a 6' long 2" pvc pipe over the other wrench and it turned pretty easily. it's all about a long pipe!

 

[chrisdoc0608]

ended up getting it off. took it to the dealer and they couldnt get it off, so i went back there to take a look bc they claimed the drive shaft would break if they took it off. turns out the morons were spining it the wrong way, i gave it one try with the vice and it came off.... woohoo time to go ride

 

[RideItLikeYouStoleIt]

Im glad to hear you got it off. Thats pretty pathetic that the dealership did that. Im putting a total loss on my sj now wish me luck.

all i have to say it that the 12/17 is awesome.... it hooks up so much harder, and the advanced timing makes my mid range rip......those mods were well worth it
