plastic chaincase cover?

754bigbore · Mar 28, 2008

What the hell is that all about? Just snowchecked a 09 800 155 rmk, anybody know if these have these cheesy covers on them? I see the dragons have a magnesium one on them. coming off my bulletproof 03 edge, this is dissapointing for a $11K sled!!

Plastic covers are a waste of time and money, they melt and warp easily just to save half a pound in weight. The magnesium will be light, but that is a fire starter so don't get that can hot or poof just like the XP's.

This is what they look like when the hood vents get stopped up with snow.

And yes it spewed oil. New one 105 $ I put heat insulating tape on the new one. No more problems.

Tape is OK... Aluminum (not mylar) coated fiberglass is much better.

No isulation plus can = problems

DaveRT.... 2006 600?

Magnesium is some nasty stuff to catch fire. I'm sure there's lots of videos on this stuff, but mag when on fire and exposed to water (snow) could do some serious damage........ not something I'd wanna be around.

Here's one example

2007 600 cfi switchback
I used an adhesive backed aluminum and fiberglass tape.

I cut and fit the tape to the cover. Has lasted over 1200 miles without lifting off the cover. I also covered a coolant hose that had the plastic sleeve melted. I discovered the melted and leaking cover when I was repairing the melted off recoil cord, at night, 5 deg. below F. in front of the cabin we rented for a week of ice fishing. It does start with the strap in the tool kit wrapped around the clutch. Must of started it a doz. times or more that day on the lake fishing. I replaced the cord with new when I replaced the cover. I also used the tape and made a shield for the recoil cord, and now keep the front vents clear of snow.

Is there an option out there to replace the plastic??? off another year sled, or an aftermarket one?

I know there was an aftermarket one made there for a while, just don't remember who it was made by.

Thanks for the info guys. Looks like I will try and find an insulating tape, but first will try and find the aftermarket supplier for the cover.

mountainhorse · Mar 31, 2008

the only aftermarket covers I've heard of are from RTI, they made the 2005 Billet aluminum covers... will not fit the 2005 - 2008

They were about $300 each from what I remember.

What if a guy fabbed up a little heat shield for it??? How big of an issue is this really????

Oh ya baby, this stuff burns. At least you know if your stranded and need to light a nice bright signal fire you could use the cover?

So what kind of insulation do you put between cover and can? Thermo-tec self adhesive or exhaust can wrap? Both?

I remember a discussion about wrapping the exhaust to keep heat out of the engine conpartment and away from other components. Conclusion was the increased temperature of the exhaust might change the tuning of the pipe.

I thought that Polaris switched to mag covers in 06? I remember the huge selling points of the 06 900 and 700 were the fact it had 10 pounds set lower in the chassis with a different chain case and the new injectors?

On a side note, my 900 is in the shop again for hitting a tree and after I duck taped it back together to be snow worthy, i blew the chain case out. Blew the seal and lost all the oil climbing a hill and on the way down it turned to mush. My plastic cover is split and leaking like a siv as well.

They should have stuck to aluminum..Its a worry you don't need in the powder, especially with a brand new sled!! Anybody had any problems with the magnesium covers? May just have to bite the bullet and buy a mag cover from polaris and fab a heat shield and/ or insulated tape. Going to have to use something on the plastic cover regardless because of the lightweight can.

What size , type and years are interchangable? Particularly to the IQ chassis.
