Splined Yoke 13 (With Collar) — Adjustable-Position PTO Yoke for Precision Drive Line Alignment
ال Splined Yoke 13-With Collar solves a problem that fixed-position yokes cannot: the need for precise, adjustable placement of the yoke on the PTO shaft to achieve optimal universal joint operating angles. In any PTO drive line, the angle between the yoke and the cross kit directly affects vibration, bearing life, and power transmission efficiency. The Type 13 collar allows the technician to slide the yoke to exactly the right position on the PTO shaft, then lock it in place with a simple collar tightening. This makes it invaluable for custom PTO shaft assemblies, prototype installations, and applications where standard fixed-position yokes result in sub-optimal drive line geometry.

⭐ Key Features & Benefits
🔧 Infinite Axial Adjustment
Collar slides freely along the PTO shaft before tightening, enabling exact yoke positioning to ±0.5 mm precision.
📐 Optimal Joint Angle Control
Precise yoke placement minimizes universal joint operating angles, reducing vibration and extending bearing life.
🔒 Simple Collar Lock
Single bolt tightens the collar for a firm grip on the shaft. No special tools beyond a standard wrench.
⚙ Custom Assembly Essential
The go-to yoke for PTO shaft builders, prototype shops, and custom drive line fabrication.
💪 Full Series Range
Available from Series 1 through 8 including heavy-duty 1 3/4″ C/E spline variants for large tractors.
🔥 Hardened Collar Insert
The collar contact surface is hardened to prevent scoring the PTO shaft during clamping.
🔄 Compatibility Information
Fits 1 3/8″ Z6, 1 3/8″ Z21, and 1 3/4″ Z6/Z20 PTO spline standards. Compatible with all tractor brands. Particularly valued by PTO shaft assembly companies, agricultural engineers, and implement prototype workshops who need adjustable yoke positioning.
📚 Selection Guide
When to Choose Type 13: Whenever you need to fine-tune the yoke position on the PTO shaft — typically during new PTO shaft assembly, custom drive line fabrication, or when correcting joint angle problems.
Positioning Method: Install the yoke loosely, connect the drive line, adjust the yoke position until joint angles are equalized, then tighten the collar.
Standard Selection: Choose B/D (1 3/8″) or C/E (1 3/4″) based on PTO speed and series based on cross kit size.
🌾 Typical Application Scenarios
Custom PTO shaft builders who need adjustable yoke positioning for optimal drive line geometry
Agricultural implement prototyping where exact PTO alignment is being determined
Steeply angled PTO connections where precise positioning minimizes vibration
Retrofitting PTO shafts where standard fixed-position yokes result in poor joint angles
🛠 Installation & Usage Guide
- Slide yoke onto shaft loosely: Position the yoke on the PTO shaft without tightening the collar.
- Assemble the complete drive line: Connect all components to establish the actual operating geometry.
- Adjust yoke position: Slide the yoke along the shaft until universal joint angles are minimized and equalized.
- Tighten collar bolt: Securely tighten the collar bolt (typically 30-40 Nm) to lock the yoke in position.
- Verify alignment: Rotate the drive shaft by hand through a full revolution to confirm smooth operation.
- Mark position: Scribe a reference line on the shaft at the collar edge for future reinstallation reference.
