Splined Yoke 04 – With Ball Attachment
The Splined Yoke 04 – With Ball Attachment is a precision-machined PTO shaft end yoke featuring an integrated ball attachment for constant-velocity (CV) joint connections, enabling smooth power transfer at higher operating angles. Engineered from forged alloy steel with splined bore connection, it provides a secure, high-torque interface between the PTO shaft and universal joint assembly. Available in multiple series to fit standard agricultural and industrial drivelines, this yoke is CNC-machined, heat-treated, and surface-coated for continuous field operation. Supplied by Ever-power with ISO 9001:2015 quality assurance and global shipping.
Splined Yoke 04 Ball Attachment – Wide-Angle CV Joint Splined PTO Yoke
Integrated ball coupling | CV joint compatible | Up to 80° angle | Φ13 & Φ16 balls
The Ever-power Splined Yoke 04 is engineered with an integrated ball coupling that connects to constant-velocity (CV) joint housings, enabling smooth power transmission at operating angles up to 80° — far beyond the 25° limit of conventional universal joints. The precision-ground ball surface mates with a matching cup in the CV housing, maintaining constant rotational speed regardless of angularity.

⭐ Key Features & Benefits
🔴
Integrated Ball Coupling
Factory-fitted precision ball enables direct connection to CV joint housings for wide-angle operation.
🔄
80° Operating Angle
Supports angles up to 80° — essential for implements with large vertical or horizontal offset.
💪
Ground & Hardened Ball
Ball surface ground to Ra 0.4 µm and hardened to 60 HRC for smooth articulation and minimal wear.
⚙️
Φ13 and Φ16 Ball Sizes
Two ball diameters cover Series 1–6 (Φ13) and Series 7–8 (Φ16) for comprehensive range.
🔄 Compatibility Information
Specifically designed for constant-velocity (CV) joint drivelines and wide-angle joint assemblies. Pairs with CV housings from Walterscheid W2300/W2400, Bondioli & Pavesi SFT series, Comer W-series, and Ever-power CV kits. Essential for front-mounted implements (snow blowers, front mowers), articulated trailers, steep-terrain machinery, and any application where the driveline must operate at angles exceeding 25°.
📚 Selection Guide
Step 1: Confirm your driveline uses a CV (constant velocity) joint rather than a standard U-joint.
Step 2: Identify the ball diameter required (Φ13 or Φ16) by checking your existing CV housing cup size.
Step 3: Match the spline pattern (B or D suffix) and series number to the specification table.
Step 4: Ensure the CV housing and ball yoke are from the same series to guarantee dimensional compatibility.
🌾 Typical Application Scenarios
🌿 Front-Mounted Snow Blowers
Large angular offset between tractor front PTO and snow blower gearbox demands CV-capable yokes.
⚙️ Articulated Trailer PTO Drives
Constant-velocity transmission required as the trailer articulates through turns.
💾 Steep-Terrain Vineyard Equipment
Hillside grape harvesters operating at extreme chassis angles need CV joints to maintain smooth power.
🌾 Front Mowers & Flail Heads
Tractor front-linkage mowers require wide-angle PTO connections for safe, vibration-free cutting.
🛠️ Installation & Usage Guide
Inspect the CV housing cup for scoring or wear — a damaged cup will accelerate ball wear.
Apply CV joint grease (typically molybdenum disulfide based) liberally to the ball surface.
Insert the ball into the CV housing cup and rotate to confirm smooth, snag-free articulation.
Slide the splined end of the yoke onto the PTO shaft and engage the retention mechanism (push pin or bolt as applicable).
Pack the CV boot with the recommended grease volume and secure the boot clamps.
Test the driveline through its full range of articulation at low RPM before operating under load.
❓ Frequently Asked Questions
⭐ Customer Reviews
★★★★★
Fitted to our front-mounted slasher on a CLAAS tractor. The ball joint handles the steep angle beautifully — zero vibration even at full deflection.
Andy L. — 🇦🇺 Australia
★★★★★
We OEM these into our CV driveline assemblies. Ball surface finish is consistently excellent — CMM results within spec every batch.
Ulrich K. — 🇩🇪 Germany
★★★★☆
Good product for our vineyard harvester. CV operation is smooth on Burgundy hillsides. Grease retention could be slightly better.
Nathalie P. — 🇫🇷 France
★★★★★
Our articulated trailer PTO drive runs flawlessly with the 04 ball yoke. No speed fluctuation through sharp turns.
Sanjay M. — 🇮🇳 India
★★★★★
Essential for our front-mount snow blower in Minnesota. Conventional U-joints couldn’t handle the angle — the 04 solved it completely.
Tyler B. — 🇺🇸 United States
