This comprehensive guide is your ticket to a successful DIY polaris xpedition clutch kit install. We’ll cover the incredible benefits, the exact tools you’ll need, a step-by-step walkthrough, and the crucial post-install care that ensures longevity and peak performance. Let’s get those tools out and unlock the beast within your Xpedition.

Why Bother With a Clutch Kit? Unlocking Your Xpedition’s True Potential

Before we turn a single bolt, let’s talk about the “why.” A clutch kit isn’t just about going faster; it’s about making your machine work smarter, not harder. The primary job of your Continuously Variable Transmission (CVT) is to keep the engine in its optimal powerband, and a clutch kit fine-tunes that process.

Here are the core benefits of a polaris xpedition clutch kit install:

Restored Power: If you’ve added larger, heavier tires, you’ve effectively changed your final drive ratio. A clutch kit corrects the gearing, bringing back that snappy, responsive feel you lost.
Improved Belt Life: A properly calibrated clutch reduces belt slippage, which is the number one killer of CVT belts. Less slip means less heat, and less heat means a longer, happier life for your drive belt.
Enhanced Low-End Torque: For technical trail riding or rock crawling, a clutch kit can provide a smoother engagement and better low-speed control, preventing jerky movements and improving throttle response.
Better Back-Shifting: Back-shifting is the transmission’s ability to downshift quickly when you hit a hill or get into thick mud. A good clutch kit makes this process faster and more efficient, keeping your RPMs up and your momentum going.

Gearing Up: Essential Tools and Parts for Your Clutch Kit Install

A successful job starts with having the right tools on hand. Rushing to the auto parts store mid-install is frustrating and wastes time. Gather everything first for a smooth, professional experience. This is one of the most important polaris xpedition clutch kit install tips we can offer.

Required Tools & Supplies:

Clutch Cover Removal Tool: A specific tool to release the clutch housing bolts.
Primary Clutch Puller: This is non-negotiable. You need the correct puller for your Xpedition’s primary clutch. Do not try to use a generic gear puller, as you will damage the clutch.
Clutch Compression Tool: A bench-mounted or handheld tool is necessary to safely disassemble both the primary and secondary clutches to swap springs and weights.
Socket & Wrench Set (Metric): You’ll need a variety of sizes, typically 8mm, 10mm, 15mm, and others.
Torque Wrench: Critical for reassembly. Clutch components are sensitive to torque specs to prevent damage and ensure safety.
Impact Wrench (Optional but Recommended): An electric or pneumatic impact wrench makes removing the primary clutch bolt much easier.
Brake Cleaner or Isopropyl Alcohol: For cleaning the clutch sheaves.
Clean, Lint-Free Rags: For wiping down all components.
Safety Glasses & Gloves: Always prioritize your safety.

Your Clutch Kit Components:

Familiarize yourself with the parts in your kit. It will typically include:

Primary Clutch Spring: Controls engagement RPM.
Flyweights (or Clutch Arms): These control how the clutch shifts through its range as RPMs increase.
Secondary Clutch Spring: Controls back-shifting and belt tension.
Secondary Helix (Optional): Some advanced kits include a new helix, which changes the shift characteristics.

The Main Event: Your Step-by-Step Polaris Xpedition Clutch Kit Install Guide

Alright, let’s get to the fun part. This section details how to polaris xpedition clutch kit install safely and effectively. Take your time, stay organized, and double-check your work. We’ll break this down into manageable phases.

Phase 1: Access and Removal

Park on Level Ground: Ensure the vehicle is stable, in park, and the engine is cool.
Remove the Clutch Cover: Locate the plastic outer clutch cover. Use your clutch cover tool or an 8mm socket to remove all the bolts holding it in place. Carefully pry the cover off.
Inspect the Clutches: Before you remove anything, take a look. Is there a lot of belt dust? Any signs of glazing on the belt? This is a good time to assess the health of your system.
Remove the Drive Belt: You may need a belt removal tool that threads into the secondary clutch to spread the sheaves apart, allowing you to easily slip the belt off. If you don’t have one, you can carefully “walk” the belt off the secondary while rotating it, but the tool is highly recommended.
Remove the Primary and Secondary Clutches:
- For the primary clutch (the one on the engine), use your impact wrench or a breaker bar to remove the center bolt. Then, thread in your primary clutch puller tool and tighten it until the clutch “pops” off the tapered crankshaft.
- For the secondary clutch (the one on the transmission), simply remove the single center bolt and it should slide right off its splined shaft.

Pro Tip: Take a marker and draw a line across the faces of the secondary clutch sheaves before you take it apart. This helps you re-align it perfectly during reassembly.

Phase 2: Disassembling and Modifying the Clutches

This is where your clutch compression tool becomes essential. These clutches are under significant spring pressure. Attempting to disassemble them without the proper tool is extremely dangerous.

H3: Upgrading the Primary Clutch

Mount in Compression Tool: Secure the primary clutch in your compression tool.
Compress and Disassemble: Apply pressure with the tool to compress the cover. Remove the bolts holding the cover on. Slowly release the pressure to safely decompress the old spring.
Swap the Flyweights: With the cover and spring removed, you can now access the flyweights. Remove the pivot bolts and pins, swap the old weights for the new ones from your kit, and re-install. Make sure they move freely.
Install New Spring: Place the new primary spring from your kit into position.
Reassemble: Use the compression tool to press the cover back down, align the bolt holes, and re-install the bolts. Torque them to the manufacturer’s specification.

H3: Upgrading the Secondary Clutch

Mount in Compression Tool: Secure the secondary clutch in the tool.
Compress and Remove Snap Ring: Apply pressure and use snap ring pliers to remove the snap ring holding the helix and spring in place.
Swap Components: Slowly release the tool’s pressure. You can now remove the helix (if your kit includes a new one) and the old secondary spring. Install the new spring and helix from your kit, paying close attention to the orientation and any specific settings recommended by the kit manufacturer.
Reassemble: Use the compression tool again to press everything back together and re-install the snap ring, ensuring it is fully seated in its groove.

Phase 3: Reinstallation and Final Checks

You’re on the home stretch! Reassembly is just the reverse of removal, but with a few key details to watch for.

Clean the Sheaves: This is a critical step. Before re-installing the clutches, thoroughly clean the sheave faces (the surfaces the belt touches) with brake cleaner or isopropyl alcohol and a clean, lint-free rag. This removes any oils or residue that could cause belt slip.
Install the Clutches: Slide the secondary clutch back onto its splined shaft. Slide the primary clutch onto the tapered crankshaft.
Torque to Spec: Install the center bolts for both clutches. Use your torque wrench to tighten them to the exact torque specification listed in your Polaris service manual. Do not guess! Improper torque can lead to catastrophic failure.
Re-install the Belt: Use your belt removal tool to spread the secondary sheaves and slip the belt back on. Ensure the lettering on the belt is facing you so you can read it.
Re-install the Clutch Cover: Put the cover back on and tighten all the bolts.

Post-Install Checks and Break-In: The Job Isn’t Done Yet

Your work in the garage is done, but now it’s time to follow a proper polaris xpedition clutch kit install care guide. Breaking in the new components and your belt is crucial for performance and longevity.

First, start the machine in neutral and let it idle for a few minutes. Rev the engine gently a few times to ensure the clutches engage and disengage smoothly.

Next, you need to break in the belt. Drive for 20-30 miles at varying speeds, avoiding full-throttle accelerations and high-speed runs. This process mates the belt to the newly cleaned clutch faces and heat-cycles it properly. After the break-in ride, allow the machine to cool down completely.

Troubleshooting Common Problems with Polaris Xpedition Clutch Kit Install

Even with a careful installation, you might run into an issue. Here are some common problems with polaris xpedition clutch kit install and how to fix them.

Symptom: Engine hits the rev limiter too easily.
Cause: The flyweights are likely too light for your setup.
Solution: You’ll need to install heavier flyweights or add weight to your adjustable flyweights if your kit has them.
Symptom: Machine feels sluggish, RPMs are too low.
Cause: The flyweights are too heavy.
Solution: Install lighter flyweights to allow the engine to rev higher into its powerband.
