What are the core mechanical specifications I should check?

Before ordering, confirm the crankshaft diameter, pulley size and rotation direction on your mower so the clutch engages correctly. This ACEBRI unit is specified for common commercial/consumer mowers and tuned to 200 in-lb torque with CCW rotation.

• Pulley diameter: 6.375 inches

How is installation and maintenance handled for this PTO clutch?

The clutch installs like the OEM units: remove the belt, disconnect battery/key, unbolt the old clutch and transfer any required shims or pulleys. ACEBRI recommends checking air gap and, if needed, removing the brake shim when excessive wear produces too large an air gap.

• Always remove key and disconnect spark before service
• Check and restore the air gap per mower manual; remove brake shim if clutch won’t engage hot
• Use supplied torque spec and match pulley alignment to avoid belt wear
• Routine visual checks: mounting bolts, electrical connector, and pulley runout

Will this clutch deliver durable performance in different temperatures?

ACEBRI manufactures the clutch from high-quality, heat-treated steel to resist deformation under heat and cold. The design emphasizes higher initial torque for positive engagement and a robust braking surface to reduce slip under load.

• Heat-treated steel construction for temperature stability
• Special manufacturing process for elevated initial torque
• Engineered braking surface to limit slippage during heavy cutting
• Quality testing intended to match OEM durability expectations
