How To Replace Polaris Pro-Ride Reed Cages

How To Replace Polaris Pro-Ride Reed CagesWorn reed petals can cause hard starting and poor throttle response. If your sled’s two-stroke, reed-inducted engine is irritable or has more than 2,000 miles, the reeds might need service. Polaris Pro-Ride reed cage replacement might seem daunting, but it’s actually pretty easy. Here’s how to do it.

 

 

 

Step 1 remove body panels

Step 1: A small screwdriver or side cutter works well to pry out plastic rivets.

Step 1: Remove Body Panels
Remove both side panels and set them aside, then remove the two screws that fasten the hood to the chassis near the handlebar riser block. While standing on the right side of the sled, slide the hood forward about one inch to disengage its tabs from the console and then lift up the hood so you can unplug the wire harness from the gauge. Remove the hood, and then pry out the plastic rivet that secures the left side of the console to the fuel tank; this allows access to the fuel pump for Step 6.

 

 

 

Step 2 remove secondary clutch

Step 2: Remove the screw that attaches the nosepan to the left footrest to make clearance when you slide the secondary clutch off of the jackshaft.

Step 2: Remove Secondary Clutch
Use the ‘L’ shaped belt removal tool from the tool kit to remove the belt from the machine. Squeeze the brake lever and use a wrench or socket to remove the bolt that holds the secondary clutch on the jackshaft. Remove the clutch and set it aside while being careful not to lose any alignment shims that are on the jackshaft; the shims tend to stick to the hub on the clutch.

 

 

 

 

 

Step 3 disconnect oil level sensor

Step 3: This connection for the oil level sensor is inside a fabric wrap near the front of the clutch guard.

Step 3: Disconnect Oil Level Sensor
The clutch guard and oil tank need to be removed to access the engine’s intake. Start by removing the hook-and-loop fabric wrap that covers the wires and connectors near the front of the oil tank. Now follow the wire that leads from the oil-level sensor in the oil tank to the male/female connector; disconnect the sensor.

 

 

 

 

 

 

 

Step 4 reposition oil tank

Step 4: Make sure the cap is tight before tipping the oil tank out of the way.Step 4: Reposition Oil Tan

Step 4: Reposition Oil Tank
Unhook the two rubber straps that hold the oil tank to the clutch guard and remove the two bolts that attach the oil tank to the engine control unit (ECU). Reposition the oil tank out of the way and secure it with a bungee cord or zip tie.

 

 

 

 

 

 

 

 

Step 5 remove clutch guard

Step 5: The voltage regulator (on left, under oil tank) and ECU do not need to be separated from the clutch guard.

Step 5: Remove Clutch Guard
Unplug the wire harness from the ECU and voltage regulator, but leave the ECU and regulator bolted to the clutch guard. Twist off the four nuts that fasten the clutch guard to the chassis, remove the clutch guard and set it aside.

 

 

 

 

 

Step 6 disconnect fuel lines

Step 6: Fittings for the fuel pump on the 2014 600 Rush Pro-R we used for this story did not require a special fuel-line disconnect tool, but it is required for earlier models. Buy a set at an auto parts store for about $10.

Step 6: Disconnect Fuel Lines
Remove the bolt that attaches the fuel filter bracket to the airbox, unhook the two fuel lines from the fuel pump and unplug the wire connection from the fuel pump. Be sure to note each fuel line’s attachment point – supply and return – before disconnecting.

 

 

 

 

 

 

Step 7 disassemble airbox

Step 7: Three separate parts stack up to make the air silencer assembly. This is the bottom part, called the air silencer.

Step 7: Disassemble Airbox
Tip the intake tube out of the airbox and carefully disconnect the wires from the temperature/air pressure sensor that’s attached to the intake tube. Remove the tube and set it aside.

 

 

 

 

 

 

Step 8 remove air silencer

Step 8: A screwdriver that is at least 12 inches long makes it easier to loosen the clamps that hold the air silencer on the throttle body assembly.

Step 8: Remove Air Silencer
Four retainer clips secure the upper airbox to the main air silencer. Unhook the clips and remove the upper box from the chassis. Now use a long No. 2 Phillips screwdriver to loosen the clamps that secure the intake silencer to the throttle bodies. With the clamps loosened, remove the air silencer to reveal the throttle bodies.

 

 

 

 

 

 

 

 

Step 9 remove throttle body assembly

Step 9: The oil pump arm has a friction-fit plastic fitting that attaches to the throttle body assembly.

Step 9: Remove Throttle Body Assembly
Use a screwdriver to loosen the hose clamps that secure the throttle bodies to the intake boots on the crankcase. With the clamps loose, carefully pull the throttle body assembly a short distance away from the engine and locate the oil pump arm – it’s connected to the assembly between the magneto and PTO throttle body. Carefully push the arm off of the assembly, tip the assembly up and out of the way and hang it with a bungee cord or zip tie for full access to the reed cage assembly. The fuel rail that is directly above the throttle body will not need to be removed from its mount on the engine.

 

 

 

 

Step 10 access reed cages

Step 10: It is especially handy to use a swivel socket to remove the intake boot bolts because other components here make for tight quarters.

Step 10: Access Reed Cages
Each reed cage assembly is secured to the crankcase with six bolts. Use an 8mm socket on a quarter-inch drive ratchet to loosen the bolts. With the bolts out, remove the intake boot assembly to access the reed cages.

 

 

 

 

 

 

Step 11 inspect, service or replace

Step 11: Reed cages don’t wear out, but their petals can erode, crack or chip. This set of had been used for 1,300 miles in a 2014 Rush Pro-R with the 600 Cleanfire engine.

Step 11: Inspect, Service Or Replace
With the cage in hand, inspect the petals for chips or cracks. Test tension by lifting the petals with a fingernail and releasing; they should make a firm “snap” noise when released. If the reed petals are worn out, you can replace them with new petals from Polaris. Otherwise, the aftermarket sells complete cage assemblies.

 

 

 

 

 

Polaris Reed Cage Service Tips

  • On reinstallation of the reed cages, note that the intake boot assembly has ‘P’ (PTO) and ‘M’ (magneto) molded on it to ensure correct orientation on the crankcase.
  • A shot of carburetor cleaner will help the throttle bodies slide back into the crankcase intake boots. WD-40 also works, but since that fluid is so slippery the boots could slip off when the clamp is tightened.
  • Put the end of a roughly 12-inch long 2-by-2 wood block against the front side of the left footrest and strike the block with a hammer. This will bend the footrest so there’s more clearance to easily sneak the belt between the footrest and edge of the secondary clutch’s outer sheave.
  • Reed cage mount bolts torque spec is 9 foot-pounds; tighten the bolts in a crisscross pattern.

  1. I am stuck and need help. I changed the outside pedals just fine. but how do you change the pedals on the inside? I am having trouble removing the cast aluminum piece in the center. Any help would be much appreciated! Thanks!
