Inner Profile Tubing – Trilobe Shape for Bondioli Series 4 PTO Driveshafts

Description

Building or rebuilding a PTO driveshaft? This 39-inch inner profile tubing gives you exactly what you need to get that custom shaft built right the first time. When you’re dealing with telescoping driveshafts, having the proper inner tube means smooth operation and reliable power transfer without binding or excessive wear that kills productivity and costs you money.

What You’re Getting

• Precision trilobe profile designed specifically for Bondioli Series 4 drivelines
• 39-inch length gives you plenty of material to work with for most applications
• 1.102-inch inside diameter with 1.417-inch outside diameter for proper fit and strength
• Heavy-duty wall construction handles high torque without twisting or deforming
• Weasler quality means this tube will outlast cheaper alternatives

Built for Custom Driveline Work

This trilobe tubing is the backbone of telescoping PTO shafts used on everything from large rotary cutters and tillers to balers and spreaders. The Bondioli Series 4 design is common on mid-to-heavy-duty agricultural equipment where you need reliable power transmission through varying shaft lengths. Whether you’re a shop building custom shafts or a farmer repairing existing equipment, this tubing gives you the foundation for a driveline that performs.

Made to Last

Farm equipment puts tremendous stress on PTO components, and this tubing is engineered to handle it. The trilobe profile distributes loads evenly around the circumference, preventing the stress concentrations that cause cracking in round tubes. Heavy wall thickness resists crushing and maintains its shape even under the heaviest loads your implements can generate.

Installation Notes

This is raw tubing that requires machining and assembly with appropriate yokes and universal joints. Make sure to deburr cut ends thoroughly to prevent damage to seals and bearings. When welding yokes, use proper fixturing to maintain alignment – a bent driveshaft will vibrate and wear out quickly. Always balance completed shafts for smooth operation.
