Splined Yoke 02 Interfering Bolt – Vibration-Proof Splined PTO End Yoke
Interfering bolt splined yoke | B/D/G/C/E sub-types | Multi-spline options | Semi-permanent retention
The Ever-power Splined Yoke 02 utilises an interfering bolt that threads through the yoke body and presses into a dedicated groove on the PTO shaft, creating a semi-permanent connection that resists loosening under the most severe vibration. Available in five sub-type variants (B, D, G, C, E) covering 1 3/8″ Z6, 1 3/8″ Z21, 8-32×38×6, 1 3/4″ Z6, and 1 3/4″ Z20 spline patterns, the 02 series is the definitive choice for fixed-installation drivelines that are rarely disconnected.

⭐ Key Features & Benefits
🔩
Interfering Bolt Lock
Hardened bolt presses into a shaft groove, creating a semi-permanent hold that cannot vibrate loose.
💪
Five Spline Sub-Types
B (Z6), D (Z21), G (8-32), C (1 3/4″ Z6), E (1 3/4″ Z20) — the widest sub-type coverage in one product family.
⚙️
Positive Shaft Retention
Bolt physically engages a groove, preventing both rotational and axial movement simultaneously.
🛠️
Grade 12.9 Bolt Included
Each yoke ships with the correct high-strength interfering bolt for immediate installation.
🔄 Compatibility Information
Designed for fixed-installation PTO drivelines where the yoke is rarely or never removed after initial setup. The five sub-type variants ensure compatibility with virtually every splined PTO shaft standard in use today, from ASAE 1 3/8″ Z6 to ISO 1 3/4″ Z20. Fits OEM and aftermarket shafts from Walterscheid, Bondioli & Pavesi, Comer, Eurocardan, and Ever-power. Commonly specified for balers, combine header drives, irrigation pumps, and forage harvester drivelines.
📚 Selection Guide
Step 1: Identify your PTO shaft spline pattern (count the splines and measure the shaft OD) to determine which sub-type (B/D/G/C/E) you need.
Step 2: Confirm the shaft has an interfering bolt groove — a small annular channel machined into the shaft body.
Step 3: Cross-reference dimensions A, B, C in the table to select the correct series number.
Step 4: The interfering bolt is included; ensure you have a correctly sized spanner or socket wrench for final tightening.
🌾 Typical Application Scenarios
🌾 Round Balers & Square Balers
Semi-permanent connection for drivelines that stay coupled throughout the baling season.
💾 Irrigation Pump Installations
Vibration-proof retention on PTO-driven pump setups that operate continuously for weeks.
🏭 Industrial Mixer Drives
Fixed installations in feed mills and chemical processing plants where downtime for re-tightening is unacceptable.
🌿 Forage Harvesters
High-torque self-propelled and tractor-mounted harvesting equipment operating in demanding conditions.
🛠️ Installation & Usage Guide
Confirm the PTO shaft has an interfering bolt groove at the correct position from the shaft end.
Slide the yoke onto the splined shaft until the bolt hole in the yoke aligns with the shaft groove.
Thread the included interfering bolt through the yoke body and into the shaft groove.
Tighten the bolt firmly using a torque wrench — the bolt tip will deform slightly into the groove for positive engagement.
Fit the cross-and-bearing kit into the yoke ears and secure with snap rings or bearing straps.
Grease all fittings, then run the driveline at low speed to verify zero vibration before full-load operation.

⭐ Customer Reviews
★★★★★
Installed on our fixed irrigation PTO pump near Mildura — rock-solid connection through an entire season without retightening.
Colin W. — 🇦🇺 Australia
★★★★★
We use the D variant (Z21) on our OEM baler assembly line. Quality and dimensional consistency are first-class.
Heinrich S. — 🇩🇪 Germany
★★★★☆
Good value with reliable locking. The included bolt was the correct hardness grade — not always the case with other suppliers.
Marco B. — 🇮🇹 Italy
★★★★★
As a distributor, we import container loads of 02 yokes. Ever-power’s quality control is the best we have encountered.
Chen Wei — 🇨🇳 China
★★★★★
Survived our entire wheat harvest on a combine header driveline. Zero bolt loosening whatsoever in high-vibration conditions.
