Pulley Measurement Note

You may see slightly different pulley measurements online for the 585521101 / Warner 5219-160 clutch path, including measurements around 5-5/16 inch, 5.35 inch, or 5.50 inch.

This can happen because V-groove PTO clutch pulleys may be measured at different points, including the belt contact area or the outer pulley flange. Match the original clutch number first, then confirm the bore, pulley profile, belt width, connector style, and deck belt path.

Before Ordering

Before ordering this 585521101 PTO clutch replacement, confirm:

• Original clutch number matches 585521101, 584800101, or Warner 5219-160
• Crankshaft bore is 1 inch
• Pulley diameter is approximately 5.35 inches
• Rotation is CCW from pulley side
• Connector style matches the integral connector-style path for this clutch
• Belt width and pulley profile match your mower deck belt
• Anti-rotation setup aligns correctly with your mower
• Mower model, serial number, deck size, engine package, and original clutch number support this path

Do not install or test-mount the clutch until fitment is confirmed. Installation marks can affect return eligibility.

Common Symptoms of a Failing PTO Clutch

• Blades will not engage when the PTO switch is activated
• PTO clutch clicks but the mower deck does not start
• Deck engagement slips under load
• Blades engage cold but stop after the mower heats up
• Fuse blows when the PTO is engaged
• Burning smell near the clutch or belt area
• Grinding, rattling, or bearing noise near the clutch
• Visible heat damage, wobble, or bearing play

Before replacing the clutch, also check the PTO switch, battery voltage, fuse, ground, wiring connector, deck belt routing, spindle drag, idler pulleys, and belt condition.

Installation and Burnishing Note

New electric PTO clutches may require a proper burnishing procedure after installation. Burnishing helps seat the friction surfaces so the clutch can develop full holding power under load.

After installation, cycle the clutch on and off at moderate engine speed with no cutting load. Avoid immediately engaging the deck at full throttle in heavy grass before the clutch has been properly seated.

For removal tips, wiring checks, torque guidance, and burnishing steps, read the PTO Clutch Installation Guide before installing.
