2012 Arctic Cat 425i - Reinstalling Air Filter

[sidmabb]

I had water in that box under the seat so I thought I had better look at the filter. By the time I got it back together I was almost in tears, and I used to work on British cars. I tried to remove the lid and it wouldn't come off until I removed the whole air box. To get it back on I had to remove the mounting bolts for that water catch box and separate it from the throttle body. I had to put the factory intake pipe on the air box 1st hoping I had it positioned right and fish it up through there. Basically the whole system is in it's own way. I also had it jacked up with both front wheels removed. Am I missing something here or is there a trick to this? I also wanted to ask if any one knows the HP rating for my machine? Arctic cat seem to think it's a secret

that sucks !! you would think changing the air filter should be as easy as checking your oil ...

i have 8 snap clips holding my lid on and i'm in and out in less than 3 minutes ...

I think yours is basically the same as the 366 model, does the lid to the air filter look like the picture? It is a bit of a pain to change it out. What I do is use a 1/4 inch socket to loosen the clamp from the air filter top to the intake snorkle. Then disconnect it from the air box. Then I pop off the three clamps (of course one is behind the unit which is real fun to get to) Then it should come out without too much trouble. You shouldn't have to disconnect the other side or take the wheel off. I turn the wheels hard left before starting and that helps. You have to work around the air deflection shield but it has enough give to it to allow slipping off the air box top.

That looks pretty close. I could not reach the back clip or the hose clamp holding the snorkel on with out removing it. Just no room to get your hand any where. I was going to take a picture today but forgot.

Reminded me of changing fuel pumps S-10 and a couple Isuzu I owned. After the second or 3rd time removing the gas tank I finally got smart and removed the whole bed instead.

Maybe I should have removed the whole front plastic/fender assembly

I was just thinking. Isn't the 366 Air cooled? Mine is water cooled and the coolant reservoir is about 1/2 inch in front of that air filter top. That explains a lot. instead of completely re-engineering for the liquid cooled engine they just stuffed things where ever they would fit.

Yes the 366 is air cooled. I didn't realize the 425 is liquid cooled.

However, the way my girl likes to hit the water holes, I might as well say its liquid cooled :roflc:

I have had the front plastics off the 366, not that hard to do but that seems a bit extreme to just change out the air filter.

That does seem like alot of work. I would see if I can place the clamp so it is more accessable next time. Maybe rotate it so the bolt/screw is facing out.

I agree with everyone else taking the plastics off is alot of work just to change the filter. Check out the service manual and see if there are any tips in there for easy removal.

Manual says rotate locking tabs and remove lid .

Luckily I don't plan on getting water in it again so It will only need checked/cleaned once or twice a year
