326108MA / 138412 PTO Clutch for Craftsman, Cub Cadet & Murray | Warner 5215-53
Overview
This aftermarket 326108MA / 138412 electric PTO clutch is a replacement for select Craftsman, Cub Cadet, Murray, AYP, Sears, and Roper lawn tractor applications using the 326108, 326108MA, 138412, or Warner 5215-53 clutch path.
Confirmed model-level applications include select Cub Cadet 2130 and 2135 tractors using the original 138412 electric PTO clutch. Craftsman, Murray, AYP, Sears, and Roper applications should be confirmed from the original clutch number or tractor-specific parts diagram.
Warner identifies 5215-53 as a replacement path for the earlier 5215-7 clutch. The original Warner configuration uses a 1-inch keyed crankshaft bore, an approximately 5.35-inch pulley, CCW rotation from the pulley side, standard mounting, and a 12 VDC wire-lead connection.
Important fitment warning: Do not order this clutch from the mower brand, deck size, engine horsepower, or appearance alone. Match the original clutch number first, then confirm the bore, pulley, rotation, belt groove, wiring, pulley offset, and anti-rotation setup.

Compatible Brands & Model Series
This PTO clutch should be treated as a part-number-first replacement. Confirm that the original clutch label or tractor-specific parts diagram identifies 326108, 326108MA, 138412, 5215-53, or 5215-7.
Cub Cadet Applications
- Cub Cadet 2130: select applications using PTO clutch 138412
- Cub Cadet 2135: select applications using PTO clutch 138412
Cub Cadet fitment warning: The 2000 Series includes several different PTO clutch and drive configurations. Do not assume that every 2130, 2135, or visually similar Cub Cadet tractor uses this clutch. Confirm the original 138412 number and physical specifications.
Craftsman & Sears Applications
- Craftsman lawn tractors: select applications using 138412, 326108, or 326108MA
- Sears lawn tractors: select AYP-built applications using the same original clutch number
Craftsman fitment warning: Craftsman tractors were built by multiple manufacturers and may use very different electric PTO clutches. The complete mower model number beneath the seat does not replace checking the original clutch number.
Murray Applications
- Murray lawn tractors: select applications using 326108 or 326108MA
- Murray-built platforms: only when the original clutch or parts diagram identifies the matching number
Murray model families may span multiple engine, deck, crankshaft, and wiring configurations. Use the original clutch number as the primary fitment match.

- Roper tractors: select applications using 326108 or 326108MA
- Additional private-label AYP platforms: only when the original clutch number matches this replacement path
Compatibility warning: AYP manufactured equipment for several retail brands. A similar chassis, deck size, or engine does not confirm that the PTO clutch is interchangeable.

Common Symptoms of a Failing PTO Clutch

- The clutch clicks but the deck belt does not begin turning
- Blades engage when cold but stop after the tractor heats up
- The clutch slips during heavy or wet cutting conditions
- The deck belt squeals, smokes, or overheats during engagement
- Burning smell near the engine crankshaft or clutch
- Grinding, rumbling, or excessive pulley-bearing noise
- Intermittent blade engagement under load
