Overview
If your PTO clutch is stamped with a Warner number, this directory can help you identify the correct replacement path.
Many mower owners find a Warner part number on the original clutch but cannot locate that number in their mower parts diagram. This happens because mower manufacturers often catalog the clutch under an OEM part number while Warner uses a separate manufacturing number.
This guide serves as a master Warner PTO clutch lookup directory and links to detailed cross-reference guides for common Warner clutch numbers.

FAQ
How do I identify a Warner PTO clutch?
Locate the Warner number stamped on the clutch housing and match the complete number, including the suffix.
Are all Warner 5219 PTO clutches the same?

What is the difference between Warner 5218 and 5219?
These are different Warner clutch families. Each family contains multiple clutch variants with different OEM cross references and fitment paths.
Can I replace a PTO clutch using only the Warner number?
Yes. In many cases the Warner number is one of the most reliable identifiers, but you should still verify bore size, pulley diameter, connector style, and OEM application before ordering.
