Splined Yoke 03 Non-Interfering Bolt – Reusable Secure Splined PTO Yoke
Non-interfering bolt | Reusable connection | Z6 & Z21 | Unlimited assembly cycles
The Ever-power Splined Yoke 03 uses a non-interfering bolt and groove system that locks the yoke firmly on the shaft without permanently deforming either component. Unlike the 02 series interfering bolt, this design allows hundreds of assembly/disassembly cycles with zero wear — making it ideal for agricultural contractors, hire companies, and maintenance workshops that regularly reconfigure drivelines.

⚙️
Z6 & Z21 Splines
Available in 1 3/8″ Z6 (B) and 1 3/8″ Z21 (D) configurations.
🔄 Compatibility Information
Suitable for shared-use and multi-implement operations where drivelines are reconfigured frequently. Fits 1 3/8″ Z6 and Z21 shafts from Walterscheid, Bondioli & Pavesi, and Comer. Popular among agricultural contractors managing diverse machinery fleets, hire companies renting PTO-driven equipment, and maintenance workshops performing regular driveline servicing.
📚 Selection Guide
Step 1: Count the splines on your PTO shaft to determine B (Z6) or D (Z21) sub-type.
Step 2: Confirm the shaft has a non-interfering bolt groove (a smooth annular channel without deformation marks).
Step 3: Match bore dimension A and ear width B to the spec table for correct series selection.
Step 4: Keep a spare non-interfering bolt in your toolkit — they are inexpensive insurance against field delays.
🌾 Typical Application Scenarios
⚙️ Contracting Fleets
Operators managing 10+ implements who need to swap drivelines daily without wear.
🔄 Equipment Hire Companies
Rental machinery that must be reconfigured for each client without component degradation.
💾 Workshop & Maintenance
Service centres performing routine PTO overhauls and driveline inspections.
🌾 Seasonal Implements
Equipment stored off-season and reconnected annually with no reassembly issues.
🛠️ Installation & Usage Guide
Verify the shaft groove is clean and undamaged — the non-interfering design requires a smooth groove surface.
Slide the yoke onto the splined shaft and align the bolt hole with the shaft groove.
Thread the non-interfering bolt through the yoke body until its tip rests in the groove without excessive force.
Snug the bolt to the specified torque — do not over-tighten, as this defeats the non-interfering purpose.
Fit the cross kit and grease all zerks with EP lithium grease.
To remove later, simply unscrew the bolt and slide the yoke off — no force, heat, or puller required.
