Can Am Commander Clutch Problems

So, you're experiencing some clutch issues with your Can-Am Commander? You're not alone. The Commander, while a fantastic machine for work and play, is known to have some quirks when it comes to its clutch system. Understanding these issues is the first step to getting your rig back to its peak performance. Let's dive into the common clutch problems, why they happen, and how to fix them.

Why is My Can-Am Commander Clutch Acting Up? Understanding the Culprits

Before we start throwing parts at the problem, it's crucial to understand why the clutch is failing. Several factors can contribute to Can-Am Commander clutch problems, and identifying the root cause will save you time, money, and frustration in the long run.

1. Aggressive Riding Styles: Let's be honest, many of us don't baby our Commanders. Hard acceleration, frequent stop-and-go situations, and tackling challenging terrain put a significant strain on the clutch system. This increased stress can lead to premature wear and tear on the belt, weights, and springs.

2. Incorrect Belt Tension: The drive belt is the heart of the CVT (Continuously Variable Transmission) system. If the belt tension isn't within the manufacturer's specifications, it can slip, overheat, and wear out quickly. This slippage generates excessive heat, which damages the belt and other clutch components.

3. Belt Contamination: Mud, water, sand, and other debris can find their way into the clutch housing. These contaminants reduce friction between the belt and sheaves, causing slippage and overheating. Regular cleaning and inspection of the clutch housing are essential for preventing this issue.

4. Worn or Damaged Clutch Components: Over time, the clutch weights, springs, and sheaves can wear down or become damaged. Worn weights can affect the shift characteristics, while damaged sheaves can cause belt slippage and uneven wear.

5. Improper Clutch Setup: The stock clutch setup might not be ideal for your specific riding style or the modifications you've made to your Commander. Larger tires, increased horsepower, or a different type of terrain require adjustments to the clutch weights, springs, and helix to optimize performance and prevent premature wear.

6. Lack of Maintenance: Like any mechanical system, the clutch requires regular maintenance. Neglecting to clean the clutch housing, inspect the belt, and replace worn components will inevitably lead to problems.

Common Symptoms of a Failing Can-Am Commander Clutch

Knowing the signs of a failing clutch can help you catch problems early and prevent more serious damage. Here are some common symptoms to watch out for:

Slipping: This is the most common symptom. You'll notice the engine revving high without a corresponding increase in speed. The Commander might struggle to climb hills or accelerate quickly.
Jerky Engagement: The clutch engages abruptly, causing a sudden jolt or lurch. This can be especially noticeable at low speeds.
Burning Smell: A burning smell, especially after hard riding, indicates that the belt is slipping and overheating. This is a serious problem that needs immediate attention.
Decreased Top Speed: A worn or slipping belt can prevent the Commander from reaching its top speed.
Poor Low-End Power: The clutch isn't engaging properly, resulting in a lack of power when starting from a standstill or climbing steep inclines.
Loud Noises: Squealing, rattling, or grinding noises coming from the clutch housing can indicate worn or damaged components.
Belt Dust: Excessive belt dust inside the clutch housing is a sign of belt wear and slippage.

Troubleshooting Your Can-Am Commander Clutch: A Step-by-Step Guide

Okay, so you're experiencing some of the symptoms listed above. Let's get our hands dirty and try to diagnose the problem. Here's a step-by-step guide:

Step 1: Visual Inspection

Remove the Clutch Cover: Carefully remove the clutch cover, taking note of the bolt locations.
Inspect the Belt: Look for cracks, fraying, missing teeth, or glazing (a shiny, smooth surface). Also, check the belt width against the manufacturer's specifications. A worn belt will be narrower than a new one.
Inspect the Sheaves: Check the primary and secondary sheaves for wear, grooves, or damage. Run your fingers along the surface to feel for any imperfections.
Check for Contamination: Look for mud, water, sand, or excessive belt dust inside the clutch housing.

Step 2: Belt Deflection and Alignment

Belt Deflection: Use a belt deflection tool to measure the belt deflection. This is the amount the belt can be pushed down between the sheaves. Refer to your owner's manual for the correct deflection specification.
Belt Alignment: Check the alignment of the primary and secondary clutches. Misalignment can cause belt wear and slippage.

Step 3: Clutch Component Inspection

Primary Clutch: Inspect the weights and springs for wear or damage. Make sure the weights move freely in their slots.
Secondary Clutch: Check the helix for wear or damage. Inspect the spring for cracks or fatigue.

Step 4: Cleaning the Clutch Components

Clean the Belt: Use a belt cleaner specifically designed for CVT belts.
Clean the Sheaves: Use a Scotch-Brite pad or emery cloth to lightly scuff the sheaves. This will remove any glazing and improve belt grip. Be careful not to remove too much material.
Clean the Clutch Housing: Use compressed air to blow out any dust or debris from the clutch housing.

Step 5: Reassembly and Testing

Reassemble the Clutch: Carefully reassemble the clutch components, ensuring that everything is properly aligned and torqued to the manufacturer's specifications.
Install the Clutch Cover: Reinstall the clutch cover and tighten the bolts.
Test Ride: Take the Commander for a test ride and see if the problem is resolved.

Upgrading Your Can-Am Commander Clutch: When and Why

Sometimes, simply replacing worn parts isn't enough. If you're running larger tires, have increased horsepower, or frequently ride in challenging terrain, upgrading your clutch might be necessary.

Benefits of Upgrading:

Improved Performance: A properly tuned clutch can significantly improve acceleration, low-end power, and overall performance.
Increased Belt Life: An upgraded clutch can reduce belt slippage and overheating, extending the life of your belt.
Better Throttle Response: A well-tuned clutch provides a more responsive and predictable throttle feel.

Types of Clutch Upgrades:

Clutch Kits: These kits typically include new weights, springs, and a helix, all designed to work together to optimize performance.
Adjustable Weights: These weights allow you to fine-tune the clutch engagement and shift characteristics to match your specific riding style.
High-Performance Belts: These belts are designed to withstand higher temperatures and stresses, providing improved durability and performance.

When to Upgrade:

You've installed larger tires.
You've increased the engine's horsepower.
You frequently ride in challenging terrain.
You're experiencing persistent clutch problems despite replacing worn parts.
