Description
When you’re building a custom PTO shaft or repairing a driveline that’s seen better days, having the right tubing makes all the difference. This 39-inch Bondioli Series 1 trilobe tube gives you the outer profile piece you need to get that power transmission system working properly again. The trilobe shape provides smooth telescoping action while maintaining proper strength for agricultural applications.
What You’re Getting
- Precise Bondioli Series 1 outer profile with 1.299-inch outside diameter
- Trilobe design for smooth inner tube sliding and reliable power transfer
- 39-inch length gives you plenty of material for custom applications
- Heavy wall construction with 0.102-inch thickness handles farm equipment loads
- Quality Weasler engineering built to Bondioli-Pavesi specifications
Built for Real Farm Work
This outer tube is designed for Bondioli Series 1 driveline systems commonly found on smaller to mid-size agricultural equipment. Whether you’re working on a rotary cutter, post hole digger, or other PTO-driven implement, this tube provides the telescoping outer section that lets your driveline adjust to changing angles and lengths during field operations.
Made to Last
Weasler builds this tube to handle the constant stress of PTO operation. The trilobe profile distributes loads evenly while the thick wall construction resists the twisting forces and impact that come with farm work. The precision manufacturing ensures smooth operation with proper inner tubes and maintains proper clearances under load.
Good to Know
This is the outer tube only – you’ll need the matching Series 1 inner tube, yokes, and universal joints to complete your driveline. When cutting to length, use a fine-tooth saw and deburr all edges to prevent damage to seals and ensure smooth telescoping action. Always check that your chosen length provides adequate overlap when fully compressed.
