OCPTY 917-04127 Electric PTO Clutch Replacement for Cub Cadet: 01008544, 01008544P, 717-04127, 917-04127 for MTD: 050615, 01008544, 01008544P for Ogura: GT1-JD08

What It Is

The OCPTY 917-04127 is an aftermarket electric PTO (power take-off) clutch that engages and disengages the mower blades on your riding lawn tractor. It’s a direct replacement for worn or failed clutches on Cub Cadet, MTD, and select other lawn tractors using the same mounting pattern and electrical connector.

Fitment & Compatibility

Before buying, check these three things:

• OEM part cross-reference: Confirmed fits Cub Cadet OEM numbers 01008544, 01008544P, 717-04127, and 917-04127; MTD OEM 050615, 01008544, 01008544P; Ogura GT1-JD08. If your tractor’s OEM part number isn’t on this list, measure carefully.
• Physical measurements: This clutch has a 4.5-inch outer diameter, a 1-inch shaft bore (for a 1-inch crankshaft), and a 3-bolt mounting pattern on 3-inch center spacing. Verify these against your old clutch.
• Electrical connection: Uses a standard 2-pin flat connector. Check that your tractor’s wiring harness matches—no adapter included.

Key Things to Know

• Quality variance: At 3.5 stars from 10 reviews, expect inconsistent QC. Some units work fine out of the box; others may have loose bearings or short lifespan. Inspect carefully before installing.
• Installation difficulty: Moderate. You’ll need basic hand tools (wrenches, socket set) and a puller to remove the old clutch from the crankshaft. The supplied hardware may need thread locker—use blue Loctite on the mounting bolts.
• Air gap adjustment: The clutch comes pre-set, but you may need to adjust the air gap (typically 0.010–0.015 inches) if it doesn’t engage smoothly or slips under load. Check with a feeler gauge.
• No warranty details listed: Aftermarket clutches often carry a 1-year warranty. Confirm with seller before buying—returns on electrical parts can be limited.

Should You Buy It

This is a budget-friendly option if you’re handy with tools and comfortable with potential fitment tweaks. It’s best for older Cub Cadet or MTD tractors where OEM parts are expensive or discontinued. If you want guaranteed reliability and easy installation, spend more on a genuine Cub Cadet or Ogura clutch.
