Polaris RZR 800 & Ranger 800 Drive Belt Guide: Which Belt Fits (2008-2014) and OEM 3211162

The 800-class Polaris machines are the ones that refuse to die. There are RZR 800s and Ranger 800s still working hard that are pushing twenty years old, and the people running them are usually the people who fix their own stuff. The problem is that parts support has thinned out, the OEM part numbers have been superseded two or three times, and searching for "RZR 800 belt" turns up belts for five different machines.

This guide sorts out which CVT drive belt actually fits an 800-class RZR or Ranger, what the OEM number cross-references to, and what to check on a clutch this old before you put a new belt in it.

Which belt fits: 2008-2014 RZR 800 and Ranger 800

The good news is that the 800-class machines almost all share one belt. The bad news is that "almost" is doing some work in that sentence, so check your year.

If you would rather run a heavy-duty aftermarket belt, there are machine-specific SuperATV options too: the RZR 800 heavy-duty belt, the RZR S 800 belt, the RZR 4 800 belt, and the Ranger XP 800 belt.

OEM cross-reference

The current Polaris number for the 800-class belt is 3211162. If you are looking at an old parts diagram, a shop receipt or a belt still in its box in your shed, you may see one of the numbers it replaced:

• 3211162 — current Polaris part number
• 3211118 — earlier number, superseded
• 3211133 — earlier number, superseded

The Hunterworks equivalent is HW 800. It is the S-dimensioned belt for this platform, made in the USA, with a stronger cord and a compound that tolerates more heat than the belt Polaris originally shipped.

One warning worth repeating: the 800 engine went into a lot of different chassis over a lot of years, including 700-class Rangers and Sportsman ATVs that use related but not identical belts. If your machine is a 6x6, a Crew, or anything that has had a drivetrain swap, call us with the VIN at (662) 631-9254 and we will confirm it rather than let you guess.

How to change the belt on an 800-class RZR or Ranger

This is a straightforward job on these machines — the clutch cover is accessible and there is no electronic nonsense in the way. Budget an hour the first time.

1. Park it properly. Flat ground, park brake on, engine cold. A CVT housing that has just been run will burn you.
2. Pull the clutch cover. Remove the outer cover bolts and work the cover off. On a machine this age expect the gasket or seal to be hard and cracked; have a replacement on hand.
3. Note which way the belt faces. Belts are directional. Look for the arrow or the printing before you take the old one out, and photograph it if you are not sure.
4. Get the old belt off. Open the secondary (driven) sheaves and roll the belt out over the top. Do not pry against the sheave faces with a screwdriver — you will gouge them and the new belt will shred on the burr.
5. Inspect before you install. This is the step everybody skips and it is the whole reason belts fail twice. More on it below.
6. Fit the new belt. Correct direction, seated in the secondary first, then rolled onto the primary. It should not need force.
7. Clear the dust and check the ducting. Blow the belt dust out of the housing. Then check the CVT intake and exhaust ducts — on a fifteen-year-old machine they are usually cracked, collapsed or missing entirely, which cooks belts.
8. Re-cover and break it in. Torque the cover bolts evenly and follow a proper belt break-in procedure. Twenty easy miles buys you a lot of belt life.

What to check before the new belt goes in

An 800-class clutch has a great many hours on it. If the last belt failed early, the belt was usually the symptom and not the cause.

• Sheave faces. Run a fingernail across them. Glazed, scored or grooved faces will not grip a new belt properly.
• Bushings and play. Grab the primary and the secondary and check for wobble. Worn bushings let the clutch cock sideways under load and chew belt edges.
• Clutch alignment. Misalignment twists the belt on every single revolution and gives you no warning at all. Our guide on how to check clutch alignment on a Polaris UTV walks through it.
• Belt deflection. Too loose and it slips; too tight and it runs hot and drags.

If you need to get the primary off to do any of this, the Polaris 800/570 primary clutch puller is the correct tool — it pulls the clutch without damaging the crankshaft threads, which is a repair you very much do not want on a machine this age. Pair it with the Polaris primary clutch holder tool to hold the clutch while you break and re-torque the bolt.

When the belt is not the real problem

If you are replacing belts every few hundred miles on an 800, worn-out stock clutching is a common culprit. The weights and springs in a clutch with that many hours on it no longer shift the way they did new, so the belt spends its life at the wrong ratio. A complete clutch system — the DuraClutch for Polaris RZR 800, the DuraClutch R Series for the 2008-2014 RZR 800, or the DuraClutch for the Ranger 800 — replaces that worn clutching rather than feeding it new belts. Our guide to choosing a UTV clutch kit covers when that is worth the money and when it is not.

FAQ

Does the RZR 800 use the same belt as the RZR S 800?
Yes. The RZR 800, RZR S 800 and RZR 4 800 all take the same belt, as does the Ranger 800.

What does OEM 3211162 replace?
It supersedes the earlier 3211118 and 3211133 part numbers for this platform.

Will a Sportsman belt fit my RZR 800?
Do not assume so. Several Polaris ATVs share the 800 engine but not the belt dimension. Call us with your model and year.

How long should a belt last on an 800?
On a healthy clutch with good ducting, a long time. If you are getting a few hundred miles, something upstream is wrong — alignment, worn sheaves, or tired clutching.

Can I change it on the trail?
Yes, these are among the easier machines to do it on. Carry a spare belt and the basic tools.
