HiTorque 210ftlb (OEM 175) BIGBearing Billet Pulley Blade PTO Clutch for Toro 103-0665 E631732 Z Master & Exmark Lazer Z Mower 1-631732 1-641300 1-633099 w/Larger Replaceable Pulley Bearing OEM Upgrad

HD Clutches are designed at HD Clutch and Assembled in the USA. Higher Torque: 210 ft-lbs (OEM 175 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.
