Clutch and Transmission Guides
How to Measure a Tractor Clutch Disc Before Ordering
Clutch disc inquiries should include the OEM number, outside diameter, spline count, hub profile, and photos of both faces.
A tractor clutch disc should be checked by OEM number first. If the number is not available, measure the outside diameter, count the splines, photograph the hub, and show both friction faces.
Production year, transmission option, and previous component replacement can affect the correct disc. International buyers should send the old disc photos before ordering so visible details can be compared.
Reference Table
| Outside diameter | Measure the full disc diameter across the friction surface. |
|---|---|
| Spline count | Count internal splines carefully and photograph the hub. |
| Hub offset | Show the side profile to compare raised hub direction. |
