Your link didn't point to anything. If you look at the diagram under "cylinder", you can see the guillotine that needs to be replaced with SS as part number 23. If you have not changed the bellows or spring, you may want to change those as well. You will need one guillotine (and bellows and spring) per cylinder.

The stock aluminum ones can melt and send parts into the cylinder, creating quite a mess. The SS is good insurance to keep that from happening...

so, the ones in the diagram are the OEM aluminum gillotines, right? Does anyone know where to get the SS gillotines?

The aluminum ones aren't sold any more, when you order from any dealer, you get the SS ones.

Not sure, but the old number 5132690 has been substituted by 5134492, which is the stock number for the 2005 model and is SS. If you have the part number 5134492 then it's SS.. or pull the valve and check with a magnet. I'm betting if they are 2 years old, they are SS, unless the parts were sitting on the dealer's shelf for a long time... (not likely, but possible..)

i hope that the pn is on the part. don't think i can check with a magnet, because SS is non-magnetic and aluminum is also non-magnetic.

Pure stainless is not magnetic, but depending on the amount of other things in the batch, it may show magnetic properties. If the valves have chromium in 'em, they may be magnetic. For example, the wif has SS Reverewear pots and pans, not magnetic. But she has some SS bowls that are. Go figure.

Another way to check... the aluminum valves are solid and smooth all the way across. The steel ones have hollowed areas on the back to decrease weight. If your valves are not smooth all the way around, then they are SS

I just added SS valves to my 03 XC 800.

A good indicator if they are SS or not is weight. Aluminum have hardly any weight to them. Not much help though if you dont have the 2 side by side to compare

The Polaris SS valves I received are hallowed out on the engine side as mentioned above by BC Dan. The core or depression doesnt go all the way through - but its definately noticeabe.

My old aluminum ones where a solid profile all the way down the guillotine.

ves

are the 800 and the700 ves valves interchangeable on some years? I just cleaned mine on 2002 700 with 8000 miles on it, they show some ware but looked good. I see low milage ones on ebay in good shape for cheap, but most or 800 0r 600 valves, my dealer wants 85.00 each for new ones. from the looks of mine,im not scared of low milage used ones in good cond. if they will fit, or am I just stupid?

The valves are specific for the engine, a valve for a 700 will be smaller than an 800. The guillotine part of the valve is the shape and size as the cylinder.

I ordered mine from partspitstop.com - they sell Polaris OEM parts at a reasonable price (Grand Rapids, MI).

Like most dealerships, they have a web app that lets you see exploded views of the sleds various assemblies - and you can see pricing and add parts right into your basket.

There are a ton of Polaris authorized dealerships out there that have this feature.

From what I can gather - aluminum valves are no longer an option.
When you order - you will most likely get the SS valves. You may see a "part number xxxx - substituted by xxxx in the description.

I also believe if your sled had aluminum valves - the springs may need to be updated as well to correct spring pressure (heavier valve??). I ordered new springs, valve nut, bellows and valves just to be sure i have the updated hardware. I know my sled was bone stock - and the springs that came out where not the same type as the new ones sent.

Some of the vets here can confirm if this is true or not.

question re: the exhaust valve (guillotine) part...

1) one of my guillotine valves separated from the dome cap/nut (threads in nut look to be completely stripped). The valve itself appears undamaged. Is it possible for the gillotine valve to slip down into cylinder enough to damage piston, etc? OR does the 'stops' prevent it from going down too far?

2) if i replace one Aluminum valve with new SS valve - does this mean i also need to replace the other valve (so that i have two SS valves)...or is it OK to have one aluminum and one SS valve?

I see that there is a SS replacement guillotine valve for the 800 VES engine.

Is there a SS replacement for the 700 VES engine?

Not sure. There are a lot fewer issues with the 700, as the cylinder has adequate cooling around the VES valve to keep it cool. The 800 has no cooling around the valve, that's one of the reasons for the upgrade to titanium and then to SS. The 700 has different part numbers for 2002, 2003, and 2004-05 so it would suggest Polaris made changes to the part as the engine evolved. I have not heard of any 700 valves failing, though.

If you replace one, you should replace the other one to ensure they are lifting at the same time to keep the engine power balanced for smooth operation.
