Magnum 425 banging/rattle noise

Hi all,

i have a Magnum 425 W958144. When I start it up the atv I hear a banging/rattle noise on the "Automatic/variable polaris transmission" case (the plastic case on the left under the driver seat).

If I lift it up a bit the rattle goes away… I looks like a FAN banging away on the plastic.

I’ve taken it to the Garage but they don’t seem to know how to fix it…

I live in Europe but I would like to try and fix it myself before going to a polaris authorized shop.

regards,

P.

Tackling the rear end

I ordered the rear differential kit with all bearings and seals. Should be here today. The manual says I’ll need a axle wrench to take the axle apart but i guess any 1 3/4 wrench will do. Are there any pointers or last minute tips from any of you more experienced people out there before I tear into this thing?

new to me, 03 330 magnum

Hi new here, new to atvs in general, my wife and i bought a 570 sportsman and thats when i found this site. but my questions are about our newest member, its an 03 330 magnum 2×4. looking for advice on simple mods that will just help overall, its for our son, but i want it to run good. i have to dig into the clutches, any upgrades to that would be great, probably needs a new belt, assuming springs and buttons in the secondary too, and just a good cleaning. how about air filters? aftermarket? k&n? it needs a filter anyway. any other hints and tips are welcome, thanks!!

330 Magnum Fuel Issues

Been a while since I was here!
I have a neighbor with a 330 Magnum that his grandkids were riding a few weeks ago and ran it out of gas. They put in some gas that may be questionable, since it started running crappy right after that. He asked me to check it out for him. I normally work on farm equipment, but have done some of my own repairs (just had the starter off my Explorer 400)
I got it in my shop and drained the gas tank and carburetor and checked the gas filter. The gas didn’t look real bad, but didn’t smell right. Kind of stale. I put in 2 gallons of new gas and it started right up. I drove it a bit and it wouldn’t pull over half throttle without the air filter, but it did fine with it in. (normal?) I drove it back to his house, 3 miles and it seemed to run great.
This afternoon they took it for a ride again and it died about 1/4 mile from his house. I got there and someone had the gas on reserve for some reason. I put it to on and choked the heck out of it and it started. Drove it to his house and seemed ok. Later on he called and said it is sputtering and died on him. ‘
Is the fuel pump maybe an issue? I would think it would either work or not. Not intermittent like this. Or a carb issue?
Thanks for any input!

newbie here

I’m thinking of buying a 2000 model 325 magnum 2×4. Price is reasonable. Problem is the rear end was replaced with a 2001 rear axle and the rear wheels don’t fit. My question being will the original hubs from the blowen axle fit on the new axle or am I looking at having to purchase new rear wheels? Any help will be appreciated. Thank you.
