Professional Installation Guide: How to Correctly Mount the 0746-136 Arctic Cat 500 6 Tower Big Pin Drive Clutch – 8 Inch 30mm
Target Audience: Repair chains, mechanic teams, off-road rental fleets
Why Proper Installation Matters
A correctly installed 0746-136 Arctic Cat 500 clutch ensures:
-
Optimal power transfer to maximize vehicle acceleration and towing capacity.
-
Reduced belt wear (extends belt life by 30-40% vs. misaligned clutches).
-
Prevention of crankshaft damage, which can lead to costly warranty claims for repair businesses.
As a 20-year manufacturer of OEM-grade clutches, we’ve documented the precise steps used by professional Arctic Cat technicians.
Tools & Preparations
Required Tools:
-
30mm clutch puller (OEM tool #0744-209 recommended)
-
Torque wrench (50–60 ft-lbs range)
-
Dial indicator (for runout measurement)
-
Belt deflection gauge
Safety Precautions:
-
Disconnect the battery to prevent accidental starts.
-
Wear gloves – clutch surfaces may have sharp edges.
Step-by-Step Installation
1. Removing the Old Clutch
-
Use the puller tool: Thread it into the clutch’s center bolt holes. Tighten gradually to avoid cracking the clutch.
-
Inspect the crankshaft: Check for scoring or rust. Polish lightly with 400-grit emery cloth if needed.
2. Preparing the New Clutch
-
Verify the 30mm bore: Measure with calipers to ensure no shipping damage.
-
Pre-lubricate: Apply a thin layer of high-temp lithium grease to the crankshaft taper.
3. Mounting the 0746-136 Clutch
-
Align the keyway: Match the clutch’s slot to the crankshaft key.
-
Hand-tighten first: Ensure full seating before using tools.
-
Torque specification:
-
Stage 1: 35 ft-lbs
-
Stage 2: 55 ft-lbs (final)
-
Pro Tip: Use a cross-pattern tightening sequence (like lug nuts) to prevent misalignment.
4. Belt & Alignment Checks
-
Belt deflection: Adjust to 1/2 inch under moderate thumb pressure.
-
Runout test: Mount a dial indicator on the clutch face. Acceptable runout: <0.005 inches.
Post-Installation Testing
-
Initial run: Operate the engine at 2,000 RPM for 5 minutes to seat components.
-
Re-torque: Cool the clutch, then verify torque (often loosens slightly after first heat cycle).
Troubleshooting Common Issues
| Problem | Likely Cause | Solution |
|---|---|---|
| Belt squealing | Misalignment | Re-check runout with dial indicator |
| Vibration | Unbalanced clutch | Verify all 6 tower pins move freely |
| Overheating | Excessive belt tension | Loosen to 5/8″ deflection |
