Specification Brand : HD Switch BulletPoint1 : Please check your clutch for the correct replacement. The ZTrak series used two very differnt clutches. The first was the Warner 5218-91 (this listing). They later switched to TCA15800 which is a very different clutch. This Listing does NOT replace the TCA15800. BulletPoint2 : BIGBearing: The Pulley Bearing Takes a lot of abuse and is often the first thing to fail. We use a Larger Pulley Bearing for a much longer life. We designed our Billet Pulley with a snapring making the bearing replaceable. BulletPoint3 : Tough Billet Pulleys: Billet Pulleys Reduce Belt Wear and Maintain Perfect Blade Speed. Our Billet Pulley Design uses a Snap Ring and Allows for Bearing Replacement. BulletPoint4 : High Torque Coil: 210ftlbs of Torque. Higher Torque Means this Clutch holds Strong Even in the Toughest Cuts. BulletPoint5 : Premium C3 Bearings: HD Designed and Spec’d these bearings with C3 Clearances, Premium High Temperature Grease and on Most Models a Larger Tougher Bearing. Cool Coil Technology: We use a Proprietary Composite Material Instead of Plastic. This Allows the heat to Escape the Clutch Faster. Less Heat = Longer Life BulletPoint6 : After-sales Before purchasing, please identify the model of the lawn mower to avoid making the wrong purchase.

Higher Torque: 210 ft-lbs (OEM is 200 ft-lbs). We add a few more windings to our coils to provide the maximum gripping strength to prevent damaging micro-slipping during tough cutting conditions. The HD Switch BIGBearing design addresses the #1 reason clutches fail with a larger tougher pulley bearing. Machined Billet Pulleys: It is easy to damage formed pulley and damage (even a small stone nick) damages the belt with every rotation. With our Billet Pulley design, we include a snap ring so the bearing is replaceable, making this clutch rebuildable. Clutches all run very hot; we use a composite material instead of plastic to allow the heat to dissipate much faster. This makes the HD Clutch run much cooler; extending the bearing and clutch life. HD Clutch wrote the Bearing specifications to include Premium C3 Rated Bearings and high temperature rated synthetic grease to combat heat. Less Heat = Extended Life.
