Polaris RZR Overall performance – Attain ten mph for Absolutely free

An progressively well known modification RZR owners are doing is taking away the plastic spacer that is on the crank shaft in the travel clutch assembly. This can raise your to RZR’s top speed by as significantly as ten mph.

The RZR’s transmission is a pulley dependent constant velocity transmission (PVT) that consists of three significant assemblies, the travel clutch, the pushed clutch, and the travel belt. The travel clutch and the pushed clutch each consist of two conical formed pulley halves, named sheaves. The transmission operates by sensing centrifugal force that lead to shift weights to force against rollers that force the movable sheave nearer to the other sheave to pinch the travel belt. The nearer the two sheaves are pushed with each other the more out the belt is pushed.

Elimination of this spacer will allow the two sheaves to come completely with each other exactly where the belt would move out to the most significant diameter on the sheaves. We have found this will raise your RZR’s top speed anywhere from 5-ten mph. Some will say this is likely against the initial design and style of the transmission, but we speculate that it was made without the spacer and was extra on later on as an straightforward way to limit the RZR’s top speed for liability causes. We have listened to some arguments that removal of this spacer will lower the everyday living of your travel belts, but we have yet to have any problems. A correct crack in interval at reduce speeds for the 1st a hundred miles on a new RZR or following a new belt is mounted is highly advisable to be certain a lengthier belt everyday living.

Elimination of the plastic restricting spacer is a straightforward process that requires a clutch compression software that can be purchased through your local Polaris dealer (component # 8700220)

1. Remove driver and passenger seats.

2. Remove panel that is behind the seats to gain entry to the outer clutch cover.

three. Remove the force rivets and fasteners holding the rear seat foundation and clear away from car.

four. With a screw driver loosen the clamp that retains the clutch outlet duct to the clutch cover and slide it off.

5. Remove outer clutch cover screws and clear away clutch cover.

six. Remove travel clutch assembly by taking away the clutch retaining bolt that threads into the crank shaft. (Dealing with the rear of the car the travel clutch is the clutch assembly on the remaining) To clear away the clutch retaining bolt you will need to protected the travel clutch assembly, aka the spider cage to retain it from spinning. A picket hammer deal with slipped into the spider cage functions perfectly for this. The clutch assembly is pressed on to the crank shaft and can be reasonably straightforward to knock unfastened by tapping on it with a rubber hammer. (This is exactly where the manufacturing facility support handbook would tell you to use a travel clutch puller, which you can get through your local dealer, component # PA-48595)

7. The moment the travel clutch assembly is taken off take it to a function bench exactly where you can put in a spring compression software. The moment it is clamped down you can loosen the six three/eight” bolts that maintain the clutch cover plate on. The moment bolts are taken off you can then loosen the spring compression software unloading the clutch spring and then clear away the cover plate. Before taking away the cover plate use a sharpie to mark exactly where it is aligned with the travel clutch assembly. They need to be bolted again with each other the exact same way since it is the way they were balanced from the manufacturing facility.

eight. Soon after the cover plate has been taken off you can slide the main clutch spring off and then clear away the plastic spacer that sat inside it.

nine. With the plastic spacer now taken off slide the clutch spring again on then with the clutch spring software compress the assembly again with each other until finally you can get the three/eight” bolts begun. Tighten them the relaxation of the way torqued to 20 ft kilos.

ten. Reinstall sheave assembly by sliding it again on to the crank shaft, then re put in the clutch retaining bolt that threads into the crank shaft. Be guaranteed you have the lock washer, thick washer and the plastic collar on the way they arrived off producing guaranteed the plastic collar centers in the clutch shaft as you tighten. This bolt needs to be torqued to 40 foot kilos.
