Splined Yoke 11 Heavy-Duty Push Pin – Large-Shaft Splined PTO Yoke
Heavy-duty push pin | Series 6–50 | Full B/D/G/C/E range | Large-bore drivelines
The Ever-power Splined Yoke 11 is engineered for heavy-duty, large-shaft PTO drivelines from Series 6 through our largest Series 50. Featuring a reinforced push pin mechanism with deeper groove engagement and thicker yoke walls, it handles the elevated torque and bending loads found on combine harvesters, large balers, industrial chippers, and mining equipment while retaining push pin quick-release convenience.

⭐ Key Features & Benefits
🔒
Heavy-Duty Push Pin
Reinforced spring pin with deeper groove engagement for secure retention under high axial loads.
💪
Full B/D/G/C/E Portfolio
All five spline sub-types from 1 3/8″ Z6 through 1 3/4″ Z20 for universal heavy-duty compatibility.
🔧
Series 6–50 Coverage
From mid-size to the largest industrial PTO shafts — unmatched range in a single product line.
⚙️
Reinforced Wall Thickness
Increased cross-section on yoke ears and bore wall handles elevated bending and torsional loads.
🔄 Compatibility Information
Purpose-built for heavy-duty and industrial PTO drivelines with large-diameter splined shafts. The full B/D/G/C/E sub-type range covers every major spline standard including 1 3/4″ Z6 and Z20 for industrial applications. Compatible with heavy-duty shafts from Walterscheid W2500/W2600, Bondioli & Pavesi 8-series, Comer Industries, and Eurocardan. Used on combine harvesters, large square balers, industrial wood chippers, concrete pumps, and mining conveyor drives.
📚 Selection Guide
Step 1: Identify your spline type — heavy-duty applications often use 1 3/4″ Z6/Z20 or 8-32×38×6 rather than the lighter 1 3/8″ options.
Step 2: Select the correct sub-type letter based on spline pattern.
Step 3: Match the series number to your shaft/tube bore dimensions in the spec table.
Step 4: Verify the push pin groove diameter and position are compatible with the 11 series reinforced pin.
🌾 Typical Application Scenarios
🌾 Combine Harvesters & Headers
Powers the high-torque drivelines feeding crops through the combine threshing mechanism.
🌳 Industrial Wood Chippers
Handles extreme shock loads from large-log feeding operations.
💾 Concrete Pump Drives
Heavy continuous-duty applications requiring large-shaft PTO connections.
🏭 Mining Conveyor Drives
Industrial-grade PTO connections for underground and surface mining equipment.
🛠️ Installation & Usage Guide
Heavy-duty shafts are heavier — use a support stand or hoist to align the yoke during installation.
Depress the reinforced push pin (may require more force than standard pins due to heavier spring).
Slide the yoke onto the large-diameter splined shaft until the pin snaps into the deep groove.
Verify engagement by attempting to pull the yoke off — resistance should be firm and immediate.
Install the heavy-duty cross kit (note: large series may use bearing strap retention rather than snap rings).
Grease all fittings generously — heavy-duty applications consume grease faster than standard duty.

⭐ Customer Reviews
★★★★★
Running Series 11 yokes on our CLAAS combine harvester in the Wimmera. The reinforced pin handles the header loads without any issues.

★★★★★
We use Series 42 and 50 in our industrial chipper manufacturing. Yoke quality exceeds our expectations for the price point.
Wolfgang H. — 🇩🇪 Germany
★★★★☆
Heavy-duty and well-engineered. The thicker walls give visible confidence. Spring is strong — you need a firm push to depress the pin.
Alexandre D. — 🇫🇷 France
★★★★★
Series 8 with C (1 3/4″ Z6) sub-type for our concrete pump drives. Running 12-hour shifts with zero failures.
