Check Compatibility Before Ordering
Universal joint cross kits may appear similar while using different bearing cap diameters or overall widths. Before ordering, confirm your existing PTO shaft matches the specifications of BYPY part number 4120S0007.
- Measure one bearing cap diameter: 42 mm
- Measure the complete cross width: 130 mm
- Confirm the joint is fitted to a compatible SFT/SO Series driveline
- Inspect the yoke bores for wear before installing the new cross kit
- Compare the original driveline identification before ordering
The C&M Difference
Collier & Miller supplies genuine PTO driveline components backed by decades of agricultural parts experience. Our team can help identify the correct universal joint by confirming the bearing cap diameter, overall width and driveline series, ensuring you receive the right replacement component and minimise machinery downtime.
Expert Maintenance Review
A failed universal joint is often a symptom rather than the root cause of driveline wear. When replacing the cross kit, inspect both yokes for worn bearing bores, cracked ears or distortion. Also check the telescoping tubes, safety guards and lubrication points for signs of excessive wear or damage.
Always replace damaged retaining clips and ensure the bearing caps seat correctly within the yoke. Excessive end float or tight spots after assembly usually indicate contamination, incorrect bearing seating or worn yoke bores. Genuine Bondioli & Pavesi cross kits are manufactured to precise tolerances to provide smooth articulation and extended service life. :contentReference[oaicite:1]{index=1}
Installation Tip
Before beginning work, shut down the tractor and implement, remove the ignition key and ensure the PTO shaft cannot rotate. Remove all old bearing cups and thoroughly clean the yoke bores before installing the new universal joint.
Press each bearing cap squarely into position using suitable workshop equipment and ensure every retaining clip is fully seated in its groove. Once assembled, confirm the universal joint moves freely without binding before lubricating the joint with the recommended grease. Refit all PTO guards and shields before returning the driveline to service.
