8TEN Gen 3 Electric PTO Clutch for Cub Cadet Warner Craftsman White Outdoor 1755341 717-3036 1742518 274-2807

What It Is

The 8TEN Gen 3 Electric PTO Clutch engages and disengages the mower deck blades on select Cub Cadet, Warner, Craftsman, and White Outdoor lawn tractors. It is a direct aftermarket replacement for the OEM part numbers listed, designed for residential lawn tractors with 42–54-inch decks.

Fitment & Compatibility

Before buying, verify these three things:

• OEM cross-reference: This clutch replaces part numbers 1755341, 717-3036, 1742518, and 274-2807. Check your current clutch’s stamped part number.
• Physical measurements: The clutch has a 1-inch bore (for a 1-inch crankshaft) and a 3-bolt mounting pattern on 4.25-inch centers. Measure your existing clutch’s bolt hole spacing and shaft diameter.
• Machine models: Fits Cub Cadet LT/LTX/GT series (e.g., LT1042, LT1050, GT1554), Craftsman DYT4000/GT5000, and White Outdoor tractors with Kohler or Briggs & Stratton engines. Not for zero-turn mowers or older single-cylinder engines with a 7/8-inch shaft.

Pro tip: Remove your old clutch and measure the depth (stack height) – typically around 2.75 inches. If your replacement is taller, the belt may rub the frame.

Key Things to Know

• Installation difficulty: Moderate. Requires removing the drive belt, unplugging the electrical connector, and unbolting the clutch. A puller tool is often needed to separate the clutch from the crankshaft – do not hammer it off.
• Quality note: This is an aftermarket (not OEM) clutch. Some users report slightly noisier engagement than OEM, but it holds up well for residential use. Check the air gap – it should be 0.012–0.020 inches. If too tight, the clutch may drag.
• Common gotcha: The PTO switch must be in the “off” position and battery disconnected before removal. Reversing the wiring polarity will blow the internal diode. The connector is usually a 2-pin flat plug – match wire colors (typically black/red or green/black).
• Belt alignment: After installation, rotate the pulley by hand to ensure the belt tracks straight. Misalignment can cause rapid belt wear or clutch failure.

Should You Buy It

Buy this if you need a budget-friendly replacement for a Cub Cadet or Craftsman lawn tractor with a 1-inch shaft and 3-bolt pattern, and you’re comfortable with moderate DIY installation. Skip it if you require an exact OEM fit for commercial use or have a zero-turn mower – in those cases, spend more on a genuine Cub Cadet or Warner clutch.
