GPR Impeller removal...?

Guy's, I know I have asked this question before, but here it is again.. Which way do I need to turn the impeller in order to remove it on my GPR...? I have been going nuts trying to remove it (turning clockwise) and this damn this does not want to budge.. I even heated the thing up.. Now somebody please tell me I am turning it the wrong way.. I promise this will be the last time I ask this stupid question (I will right it down this time)..

Thanks in advance, Charlie Z

Left handed threads, do the exact opposite of what you normally do to loosen a nut.

When you put the impeller back on, paint the threads with an anti-seize so that it is not hard to remove the next time.

this thing is killing me!

Salty, Thanks for the reply... I looked at my stock impeller threads and noticed just what you are telling me (clockwise to remove). This damn thing is frozen on there... I need to take it to my buddies shop where his vice and table are a little more stable..

Thanks, Charlie Z

Charlie,

You need to put it on a stable vice, heat it up real good and turn it Clockwise. I had a difficult time removing the impeller, it took almost 20 minutes with the heat gun and a strong wrench to finally remove my stock impeller. If you can't do it yourself, I would suggest that you take it to a local shop, they do it for a few bucks and save yourself some hassles...

When removing impellar's that have been put on with locktight I would suggest heating with a propane torch. The locktight 'gives' at approx. 300 F. I dont know how hot your heat gun gets but I would think it would take forever to achive that kind of temp. My 2 cents. Take it or leave it.....:

While on this loc-tite topic, do all of you reapply loc-tite on your impellers? I never do and have never had a problem. I do however put antiseize compound on the threads and the impeller comes right off when I swap. Is this a good idea? I also never use loc-tite on my pump bolts. I use antiseize on those babies as well and the same goes for spark plugs. Come to think of it, I never use loc-tite on anything. For intake grates, rideplates, sponsons I use a dab of silicone on the bolts

Zoltan,

my mechanic threw me for a loop when last I took the GPR to him for impeller swap and he put anty seize on all bolts and the prop.

Told me he never uses anything else!

Mario temps are falling?

I guess I am not alone then. No one ever told me about this and I just went on my own instincts. I hate it when bolts strip or torx, phillips and allen heads round themselves out. Loc-tite has it's purpose on engine components, but not on areas I frequently tinker with like the pump, imp., rideplate, intake grate and sponsons.

Same here. Only, on the 650 I had to pull it out and reseal the crankcase because I used blue and it didn't hold. Otherwise, I don't use any in the same locations you say, mainly because if something *were* to come loose, I'll probably catch it as I'm always in the pump. Nothing loose other than the crankcase, yet.

You just have to get a stable and substantial vise and a looooong cheater bar)) Who was it that said' Give me a place to stand and I can move the earth' ) or something closely equivalent to that. hehe oh yea if by some chance it's a stock yamaha prop, use box end only as the open end will collapse the integral nut.

Charlie, you can tell by simply looking at the blades. The leading edges of the blades are going to be turning in a direction that forces a tightening effect when it's spinning/processing the water through the pump(if not the impeller would just turn right off the shaft) So the water in effect keeps the impeller tight on the drive shaft(counterclock wise). So you loosen the opposite direction which is clockwise or reverse threads. That's how to remember!!!!! (or reverse threads). You should analyze the motion/direction of the impeller that is going to keep it on the shaft then you can tell which way to turn to loosen. Don't try to remember per say just look at the impeller and pump and you can tell by blade design etc.... Hope this makes
