#23866763 07 MXZ 600 clutch question

Posted by xcrsp440 on 06 May 2021 - 07:32 AM

I had a 500ss that would not smoothly engage. Almost impossible to load on a trailer as you could not make small adjustments, it would move a foot each time clutch engaged.
I knew this wasn’t right. My 600 HO has a higher engagement rpm, but I can inch it along easily.
Took the clutches apart, cleaned out old debris and dust, made sure everything moved smoothly, installed and adjusted a new belt. Instant success. Much more driveable.

Never hurts to measure the crank runout either

Is the clutch kit for a button or roller style clutch?

#23794257 2003 Rev 600HO motor swap out

Posted by xcrsp440 on 12 March 2021 - 09:21 AM

The cranks on the 2003 had PTO seals that were not held in place with a plate. In later years they added enforcement to keep them seated.
My 2003 had the seal dislodged when I popped the clutched off. I tapped it back in place, but never trusted it after that.

I put a new skidoo short block in my 2003 a few years ago. It was a good decision. Rest of the sled was in good shaped, track was fresh, shocks were replaced. Had some clutch mods recently done too.
It had about 9k miles on it.
For $1600 I got a fresh sled. Did the work myself. Still runs strong. I could not have purchased a better running used sled for that price.

Probably 4 years ago a SkiDoo short block for a 600 HO was around $1600 plus a core charge.

#23770265 Using oil

Posted by xcrsp440 on 01 March 2021 - 12:27 PM

There is a port on the back of the engine that leads to the cavity holding the injection oil that lubes the water pump worm gear. The tube coming off of it leads to the oil reservoir. When you top off the oil tank, some can flow to this cavity by design.
If you park the sled top off the oil tank and Mark the oil level. See if it drops without the engine running. The longer it is parked the better, mine took the summer storage season to fill the engine.
You could try pressurizing that cavity with 5 lbs, see if it holds it too

With how clean one side is, my assumption is it was sucking in coolant.
Did you smell it in the exhaust?

#23764877 Overheating

Did the cylinder head discolor? Perhaps turn a golden color?

Hydrolock occurs when the engine ingests a large volume of a liquid into the combustion chamber. Can’t compress the liquid so the engine quits spinning. Often causes bent connecting rods.
I don’t think it happened based on your pics.

#23764129 800r seizure - Crankcase full of gas

Posted by xcrsp440 on 26 February 2021 - 10:57 AM

Did it seize, or did it hydrolock and stop turning?
I don’t know if enough fuel can be supplied to a running engine to hydrolock. Mine happened when the sled was parked and oil filled the crankcase.

#23735145 Made a mistake!! Ran my 05 Gsx with the oil light on. Damage??

Posted by xcrsp440 on 14 February 2021 - 08:59 PM

If it ran without oil and you now have low compression. You won’t get by with just a fresh top end. Your crank bearings need oil too. Figure on replacing the crank. Or get a new short block.

#23731953 Economy skis

Posted by xcrsp440 on 13 February 2021 - 10:57 AM

Depending on where your skis are worn, look at some navigators. They are a plate that bolts to the front of the skis.
I had a hole worn thru the front, the navigator covered it and really reduced darting too.


#23731943 Recoil/starter cup

Posted by xcrsp440 on 13 February 2021 - 10:52 AM

Don’t take it apart. There is a metal clip that holds it all together. It bites into the plastic. When you take that off it won’t bite the same as it did before. It will work its way off and then the recoil pieces fall behind the flywheel and bounce around the stator. Then you have a bigger headache.

As above there is a bolt thru mod people do to keep this from happening.

#23728685 2008 GTX 500SS: seized ?

Posted by xcrsp440 on 11 February 2021 - 07:24 PM

Keep us updated please.
Often people ask what is best replacement piston for redoing a top end. I shake my head, because a top end usually just doesn’t fail on its own. The busted piston is the most obvious sign something is wrong. Simply replacing it may mean it just happens again. And then the new pistons get blamed. So many upstream failures can cause the downstream damage.
A thorough investigation needs to happen before slapping in new parts.
