Removal of Chain Case on snowmobile

So I got this 98 Polaris 600 XC snowmobile that the chain case is leaking. I mean, when you put in oil, it immediately runs out the bottom.

Does anybody have a service manual describing how to remove this and replace the gasket ?? Looks like the last time, the belly pan was loosened up by removing some rivets.

Any body ????

Should just be bolted on .. no? Last one I worked on was a '78 J/D Trailfire , so I'm a little rusty ...

This pic might help. Looks like just a few bolts & your in business. http://www.nielsens.com/fiche_section_d ... &fveh=6302

Ruck, I had one of these.
I had to remove the cover to install Reverse. It is simple: Just 3 or 4 bolts hold it on. The gasket is more of an O-ring style moulded rubber. Sounds like you have a O-ring that broke or slipped, or you have a damaged chain cover. Hopefully you can remove the cover, put the O-ring back in position, then reinstall the cover, and your good to go. A 10 minute job.
You MIGHT have to remove the Tuned Header first.

Smitty,

Thanks for the link.

Chris, the issue is getting access to the lower bolt. Damn molded belly pan covers it up. I'l have to look at it again tonight.

I got to get this thing ready for the next storm coming in. Now if only the shoulder holds together enough for me to drive the damn thing.

Yeah, I forget if I went thru the Belly pan, or got a socket on the nut from inside the belly pan, underneath the chaincase. There might be an access hole for that bolt in the belly pan, but my memory fails me. If you can't get the bolt off from reaching UNDER the chaincase, you can drill a access hole thru the belly pan, then just use some RTV Silicon to plug it back up when your done. I do not believe I had to do that.
If I find my manuals, I'll copy the page for doing this.

That's the issue Chris. The belly pan is an inverted "U"for the IFS bar to attch to the frame. And the bushing to that bar is shot(will be replaced with this repair) and the sleeve is stuck in place. Bringing tools home from work to remedy that !!!! It will be out tonight.....

Next time, buy a Ski-Doo!!

Nope no doo-doo here..........Although the E-tec's are looking better and better !!!

Got it fixed and ready to fly tomorrow after I wake up. Hopefully there will be too much snow to go to work and I can play catch up on some mileage. The grandkids got cheated last weekend. Everything right now is getting the sled ready for my Maine trip the first week of March. And I got to get some cars out of the shop until then. I'll be missing a few trips to Potter but that is OK. Maine is where it's at !!!!!!!!!!!!! Now if only we can send some snow their way........

I miss snowmobiling. Like I said, the last one I rode was a '78 John Deere Trailfire 440! Had a Kawasaki engine ... wasn't a bad sled for the price, but compared to whats out there today, it's a dinosaur to be sure. The suspension is akin to placing those silver or black screen door closer pistons on the skis ... My ol' man holed a piston during the first 300 miles ... But like I said the price was right. I think it was $700 out the door ... next to the lawn equipment!

I bounced that thing off a few trees in my learning stages. My ol' man had to pull all the trim off the cowl & repaint the whole thing. I was about 40 lbs. soaking wet on a 400lb sled. I must have been a funny sight going down the trail at 50 mph!

As I reported last night I fixed it. Pulled it out of the heated garage and put it in the shed all ready for this AM.

Well I wake up as most around here to being in the middle of a blizzard. Well not technically a blizzard but it was snowing like all get out. Couple of passes with the truck mounted snowplow. And good to go.....NOT. Sister-in-laws Alaska Cast Console had issues last night. Diagnosed it as a bad control box for the feed. It defaulted to max. Was pushing hot ash off the grate and when cooled left a plate sized klinker that shot down the stove. A trip to the local dealer and all is well again.

A couple more passes with the truck and an attempt to use the backhoe to move some snow around. It was blowing too much to use the backhoe so time for a sled ride.......down through the field and due to the heavy snow cover and a real bad right shoulder I can't turn to the right too well at all. I get it stuck about 150 yards from the shed. It bogged down in 2 feet + of snow. A call to the son in law for help...We shoveled and moved 5 feet or so and then shoveled again. After the 5th or 6th time, I call it quits and go get the tracked snowblower to make a path through the field for the last 75 yards. 2 hours later we're both soaked through and through but the sled is back in the shed.

I know one thing for sure, for now I will keep it on the flat field in sight of the house. I'm getting too old for *censored* like this and having a bum shoulder doesn't make things any easier.
