Dust ingestion

I have a 2013 800 trail. Just spent 3800 dollars for engine rebuild due to what the dealer called extreme dust ingestion. I bought this with about 2600 miles on it and only put on about 300 miles last summer. Now that I have a new motor what is it normal for extreme dust ingestion on these 800's or did the previous owner just not take care of it? I definitely don't want to be paying for another motor anytime soon. Any thoughts, suggestions, tips what have you I will listen to.

Re: Dust ingestion

It would be smart to install air box in bed like seen in this pic, it runs a Donaldson filter and keeps engine spotless with out hardly ever needing to replace filter.

Dust ingestion

My wifes 13írzrS 800 is a stock setup with 2,100 miles on it, i change the stock filter regularly, we live in west texas so plenty dusty in summer. I have never seen a speck of dirt or sand or anything in her intake once you remove the filter. I see no need to but extra stuff if the stock setup is maintained and it works
Now if all we rode was sand then hell yes the donaldson is a great idea

Re: Dust ingestion

I guess it depends on how much you ride, I put 3 to 4 thousand miles a year. looks like you don't ride much.

Re: Dust ingestion

I have a 2008 800 I bought used years ago. After coming on this site and read all the issue's with the stock intake system letting dust in I bought an UMP intake like a lot of people here. I use a Donaldson are filter in it from the suggestions on this site as well. I have over 5000 miles and no issue's with the motor.

Re: Dust ingestion

I recently purchased a 2011 800 S. When I removed the airbox cover I was shocked at the amount of dust inside. After searching this site I decided to do the "Grumpy Mod". Once I cut the hole for the external filter for the mod I discovered several areas where dust was getting into the air intake. The rubber around the airbox air horn and the rubber around the clutch intake air horn. I also determined the airbox lid gasket was leaking and two of the airbox clips were broken. This rzr had a foam filter inside the airbox and I could see dust inside the throttle body tube. What I have done is silicone sealed everywhere there was the potential for air leakage around the air horns and seams. I replaced the airbox lid gasket & clips and replaced the foam filter with a factory paper filter as they filter down to the smallest particle level. My "Grumpy Mod" filter is paper also as I figure the $6 to replace it is cheap insurance and should help keep the airbox filter clean. I will monitor inside the airbox and if I see any dust I will know I still have a leak in the system. Good luck!

I highly recommend the S&B particle separator. I’ve got a ‘17 without and a ‘19 with a particle separator and note a huge difference after a day of riding the exact same terrain.

The bulk, noise and price are nothing when compared to rebuilding a motor.

Re: Dust ingestion

Don't believe that s and b make a particle separator for an 800. I had an 800 's and when i sold it , it had over 16,000 miles on it. The engine was never touched. Only used stock Polaris filters. Just kept up on it and made sure that i cleaned it often and replaced it when needed. I worked at a dealer and have seen plenty of 800 come in with dirt ingested engines due to lack of maintenance.

My mistake. Didn’t realize I was in an 800 specific forum. Must be the phones fault...

Re: Dust ingestion

Keeping the air filter element clean is highest priority on a RZR 800.

The combustion air intake is that point in the center of the bed, right behind the seats. It draws air in from the underside and straight into the air box.

A very dusty location..and all the dust is on the outside of the air filter element.

The Polaris air filter element is a very high grade filter media. But you have to keep it clean so the dust doesn't break through and get into the throttle body. Dust into the throttle body gets turned to mud as it passes the fuel injectors. And that scores cylinder walls rather quickly, which allows oil past the piston rings. Which runs the motor out of oil...and there you are a dusted engine.

There are a number of air cleaners and/or air filter elements out there. But Donaldson makes the air filter element for Polaris and the Vent Racing air cleaner is a Donaldson. Do not use K&N filter elements, do not use NAPA air filter elements. Both will let dust through pretty quickly.

After each trip, remove the air filter element. Tap the edge of the rubber end on a table to knock the dust off. Use a shop vac, nozzle about an inch from the filter, and suck the dust off the element. Look up the air cleaner outlet, if there are any signs of dust in the inlet, then inspect the intake ports in the head for signs of "mud". If its present...probably too late.

Re: Dust ingestion

Thanks for all the replies and suggestions. As I said I bought this used and do not know any history of maintenance but judging by other things I have seen it was not maintained well. Does anyone recommend blowing the filter out with air after each ride? Definitely think I will get a sock for the element.

Re: Dust ingestion

I live in southern NM, and it gets very dusty here, especially in the summer. I bought mine used too, from the original owner. However, he installed a K&N filter on it, and I didn’t know any better. I noticed that is used a lot of oil, and found out the engine was “dusted.” I had the local dealer rebuild the top end, to include pistons and rings. It was costly, but I got the RZR for a good price so I didn’t feel that I got completely burned.
I only use paper filters now. No, I do not recommend blowing it out with the air hose.

Re: Dust ingestion

Amazon sells a paper filter for $15. That what I use all the time. There is no way I could afford changing a Polaris OEM filter as often as we have to do out here in the desert.
