Genuine BYPY® SFT Inner Profile Tube
Restore the telescoping section of your heavy-duty PTO driveline with this genuine BYPY® SFT inner profile tube. Designed to suit compatible Bondioli & Pavesi® SFT/SH and SFT/SO Series PTO shafts, this genuine replacement inner tube delivers the strength, precision fit and durability required for high-horsepower agricultural applications.
Part number 122553000 features the genuine SFT four-tooth profile and is manufactured to slide smoothly inside the matching outer profile tube while transmitting high torque under changing operating lengths. It is the ideal replacement for inner tubes that have become bent, twisted, cracked or excessively worn through years of demanding field use.
Manufactured with an outside diameter of 61.7 mm (D1) and a wall thickness of 5.75 mm (T1), this genuine Bondioli & Pavesi replacement tube maintains the original driveline geometry and telescoping performance while allowing damaged components to be repaired without the expense of replacing the complete PTO shaft.

Check Compatibility Before Ordering
Inner profile tubes can appear similar while using different profile shapes, outside diameters or wall thicknesses. Before ordering, confirm your existing driveline matches the specifications of BYPY part number 122553000.
- Confirm the driveline is an SFT/SH or SFT/SO Series
- Verify the tube uses the genuine four-tooth SFT profile
- Measure the outside diameter: 61.7 mm (D1)
- Measure the wall thickness: 5.75 mm (T1)
- Inspect the mating outer profile tube for excessive wear
- Compare the original driveline identification before ordering
The C&M Difference
Collier & Miller supplies genuine PTO driveline components backed by practical agricultural parts knowledge. Our experienced team can help identify the correct replacement tube by confirming the driveline series, profile type and critical dimensions, helping minimise downtime and ensuring the correct fit the first time.
Expert Maintenance Review
When replacing an inner profile tube, inspect the complete telescoping assembly. Excessive wear on the outer tube, worn yokes or damaged universal joints can significantly reduce the service life of the replacement component. Check both sliding profiles for twisting, scoring, corrosion or excessive rotational clearance before reassembly.
Clean both telescoping members thoroughly and apply the recommended PTO grease before assembly. Correct lubrication allows the profiles to slide freely under load while reducing friction and wear. Also inspect the PTO safety guards, bearing support rings and retaining components before returning the driveline to service. :contentReference[oaicite:1]{index=1}
Installation Tip
Before beginning work, shut down the tractor and implement, remove the ignition key and ensure the PTO driveline cannot rotate. Remove the damaged inner tube and inspect the mating outer tube for distortion or excessive wear before fitting the replacement component.
Lightly grease the sliding profiles and confirm the telescoping action is smooth throughout the full operating range without binding. After assembly, verify the universal joints articulate freely and all PTO guards and shields are correctly fitted before returning the machine to service. Never operate a PTO driveline with damaged or missing safety guarding.
