SXR How to get the pump off!

[kawi_mods]

Hey Guys

Im trying to get the pump off my SXR i have the nozzle off and the pump cone how do you get the back shaft (marked in red) out with out the tool???


The problem I'm having is I'm turning the hole engine over.

Are you just trying to pull it off the ski or pull it apart to change the bearings?

If just trying to remove it from the ski, you only have to pull the four bolts holding it to the hull (P/N 92002B) in that picture. Then just pull it backwards....it can be stubborn.

That piece is threaded into your impeller. So you have to have your impeller removed by using a special tool inserted into your impeller, then a wrench on the flats of that shaft and unscrew it.

+1 to what Waternut said, if you are just trying to remove the pump from the hull, unbolt the 4 Allen head bolts then pull/persuade backwards until it slides out.

ya all I'm trying to do is pull the hole pump so that i can drill and tap another hole for dual cooling

so that will work i can just pull straight back and it will slip off the splined inner shaft?

Yep, if you have the 4 Allen bolts out, then it's just a matter of working it off. You can gently pry, but your pump shoe is plastic, so don't pry too hard, just watch what you are doing.

ya thats got it off i just slowly forced it off

Now the fun will be putting it back on haha

Thanks guys!

Grease up the splines well. Should slide back on nice and easy.

Alright cool now another question

i hear boring the stock nozzle will give a little more bottom end cuz it allows more water though, is that true if so what nozzle is bored and what size? can you do both ( In the pic the black steering nozzle and or the regular nozzle?)


What are the stock sizes of both and how big can i go?

 

[john zigler]

bore the aluminum pump reduction nozzle. 80mm is a good size. leave the steer noz. ( plastic piece).

changing to a wet wolf freestyle cone will also let the water collapse sooner as it comes out of the stator vein section, and will give similar results to a larger exit nozzle. we have done both before, with good results on some skis / set ups.

alright thats exactly what i was looking for. also i forgot to say i have a blowsion stubby cone on there does that work well with the bored nozzel?

Also i am going to drill and tap the pump for dual cooling where should it be drilled?

I was thinking where the red holes are in the pictured.?


Is that an ok spot to drill and tap?
i thought about the other side where it looks like there should be one but it would interfere with the steering cable

bump

 

[Cannibal]

Mine's drilled exactly across from the stock one, so in the first picture, you stock one is located at 3 o'clock, you can add another one at 9 o'clock.

Then loop the hose under the pump reduction nozzle to the tube.

ya i was thinking that but does it clear the steering cable bcuz it is in line with the cable and when i mocked it up it looked like it would interfere with the cable?

If it doesn't interfere than great and i have my answer!

 

[Cannibal]

That's where mine is, no problems with cable interference. Might want to mock it up and maybe put it a little higher or lower if needed, but it works for me.

 

[kawi_mods]

alright cool is yours on a SXR? cuz if so than i don't need to mock it up if you've done it

 

[Cannibal]

Yep, SXR, it was done when I bought it. I can snap a pic when I get home, pump is already out, so no biggie.

 

[kawi_mods]

Ya That'd be sick thank's man! are you running a wet pipe? if so can you snap a pic of the cooling line set up?

THANKS AGAIN!

 

[Cannibal]

Everything is out of the ski, so no pics there, sorry. But I was running one line to the exhaust manifold for engine cooling with 2 coming from the head, one went to a pisser, one went up to my hot hands.

The other line went to the bottom of my wet pipe head pipe, then out the top of the head pipe to a T with one going to a pisser and the other going to a Jetworks flow control valve then to the stinger fitting.

My water temps around here never really get out of the 60s, if you rode in 80+ degree water, your setup might need to be different.

OK not quite following so i took a pic and marked out what i was thinking


(Green) is water in 1 that will be the new hole tapped in the pump going to the head.
(Blue) is water in 2 and will be the stock hole off the pump going to the exhaust manifold.
(white) is the exhaust out coming out of the head pipe bottom to the back of the ski pump area or at least i think thats what it is.
(Pink) is the water outlet coming off the head to the pisser.
(Red) is the water out of the top of the head pipe to the pisser.
The Exhaust chamber is still "T'd" into the (pink) line to the pisser.
(Orange) that i believe is the gas tank vet and it went to the stock pole now i Have RRP so what should i do with it??

Will that work? If I'm wrong please correct?? Any better ways of doing?
All thoughts and comments would be great THANKS!
