Description
When your driveline needs custom sizing or you’re rebuilding an existing PTO shaft, having the right inner tubing makes all the difference. This 39-inch trilobe profile tubing is designed to telescope smoothly inside matching outer tubing, giving you the variable length needed for different implement hitching positions while maintaining solid power transfer from your tractor’s PTO.
What You’re Getting
- Precision trilobe profile ensures smooth telescoping action without binding or play
- 23.8mm cross and bearing diameter matches Bondioli Series 2 specifications exactly
- 4.1mm wall thickness provides the strength needed for agricultural power transmission
- Standard 39-inch length fits most common driveline applications
- Weasler quality construction means reliable performance season after season
Built for Agricultural Power Transmission
This inner tubing is specifically engineered for Bondioli Series 2 PTO systems, commonly found on mid-sized tractors handling everything from rotary cutters to hay equipment. The trilobe shape isn’t just for looks—it transfers torque efficiently while allowing the smooth in-and-out movement needed when connecting implements at different distances.
Made to Last
Agricultural PTO shafts take serious abuse, and this tubing is built to handle it. The precision-formed trilobe profile maintains its shape under load, while the substantial wall thickness resists the twisting forces that can destroy lighter tubing. Weasler’s reputation for PTO components means this part will keep working when cheaper alternatives fail.
Good to Know
This is inner tubing only—you’ll need matching outer trilobe tubing to complete your telescoping assembly. When assembling, keep both tubes clean and properly greased at the contact points. The trilobe shape naturally sheds debris, but regular maintenance keeps everything sliding smoothly and extends component life.
