Honda 23710-ZE1-613 Shaft P.T.O. 26T

The Honda 23710-ZE1-613 Shaft P.T.O. 26T transfers engine output to PTO-driven components. Wear, damaged splines, or poor engagement can interrupt power delivery and affect attachment operation.

This part may fix the following issues:

• PTO attachment fails to receive power.

• Shaft splines become rounded.

• PTO connection slips under load.

• Excessive rotational play develops.

• Drive engagement becomes difficult.

Torque Loss

Quick Check: Operate the PTO attachment under load and observe whether rotation slows while engine speed remains unchanged.

Fix Suggestion: Restore full torque transfer by renewing the shaft if worn splines no longer grip the mating component securely.

Prevention Tip: Engage PTO-driven equipment only after the coupling is fully seated.

Spline Wear

Quick Check: Examine the spline teeth for flattening, chipped edges, or polished contact surfaces.

Fix Suggestion: Exchange the shaft before damaged splines begin wearing the connected drive hub.

Prevention Tip: Remove dirt from spline surfaces before reconnecting attachments.

Loose Engagement

Quick Check: Rotate the shaft by hand and feel for excessive movement where it joins the driven component.

Fix Suggestion: Re-establish a firm connection by replacing the shaft once excessive play is confirmed.

Prevention Tip: Tighten retaining hardware whenever PTO components are serviced.

Coupling Resistance

Quick Check: Attempt to connect the PTO attachment and note any binding during installation.

Fix Suggestion: Realign the mating components and install a new shaft if worn splines prevent smooth engagement.

Prevention Tip: Avoid forcing PTO parts together during assembly.

Customer Experience: The PTO attachment started engaging without hesitation after replacing the worn shaft. Power transfer remained steady through several mowing sessions with no noticeable slipping.
