Alternate Method to Seal Clutch Case

After having the same water in the clutch case problem as others, I used a different way to seal the cover. I didn't care for the
grease and silicone way so I used an RV tape used to seal roof leaks. It sticks to just about anything and can be scraped off to remove. It is the number one RV sealing tape so I figured I'd give it a try. I used it in between the cover screws since the gasket is crushed between the screws but open gaps between them. And after many good size puddles and water holes I opened the drain screw and bone dry! Eternabond Tape, thought I would pass this along.

Outsiders Motor Company has a seal kit for the Sportsman 570. Haven't purchased the kit yet, but I think I eventually will, no problems with my clutch cover leaking yet.

In regards to the link indyred570 posted, are people having problems with the airbox sucking dirt with the factory gasket? Although its new, I have thoroughly checked mine and it seems to make an airtight seal.

No problems here, just posted the link as an option to a better gasket if the oem looked bad or leaked.

From what I've seen, most leaks, especially on the newer machines, are from behind the INNER cover. I've never had any leaks through the outer cover so long as you have a good seal and you put the cover on straight and alternate tightening the screws. They also don't need to be too tight. Just good and snug. I go through some pretty deep river crossings to get into the back country and have never had a wet belt.

Hey rockhound thatís a good idea! Iíve been using a peelable rtv used in service applications and thatís worked well too. Always like to see other ideas that work well.

Like most have said here already, a lot of leaks are at the back cover.

I had already taken the back cover off and did silicone the ring and new zip tie, just wanted to share the front cover as an alternative to grease and silicone. But hey, whatever works for everyone else is good too!

What I'm saying rock, is that I've never seen any reason to add anything to the outer cover. As long as you have a good seal installed it won't leak under normal conditions. I suppose if you stay submerged a lot you might need something extra. I have had to spend an hour or two of shop time trying to get the RTV OFF some machines to access the clutches because the owner THOUGHT they were waterproofing it. It was an expensive lesson for them to have to pay me a couple hours labor for what should have been a 1o minute job just to get the cover off. Not to mention that once you go down that road it will NEVER seal properly again unless you spend a lot of time scraping and pealing the crap off there.
