Complete Shield Kit Fits New Holland BR7090 BR780A
Best for: New Holland baler setups needing a dedicated shielded CV kit. This kit replaces OEM 87517842 and features an 80-degree CV joint for smoother operation with limited space behind the implement. It is well suited for hay baling and forage operations where PTO positioning can vary.
Why picked: The kit provides a compatible shield and CV joint configuration for BR7090 and BR780A units, streamlining maintenance and replacement. The 80-degree CV is designed to reduce input shaft binding at sharp angles during baling cycles.
Caution: Verify exact s/n and compatibility with your model to avoid mismatches. Some installations may require additional mounting hardware not listed in the kit.
CV PTO Driveline Tractor Half Shaft 1-3/4″ 20 Spline Yoke
Best for: Tractors using Star Profile Tubes with wide-angle CV joints, providing smooth power delivery across a broad range of motion. The 55-inch length supports mid-length drive configurations common in older or mid-sized tractors.
Why picked: The CV design helps cancel torque fluctuations inherent in single Cardan joints, improving ride quality and machine operation under heavy field tasks.
Caution: Check the exact spline size and end yoke to ensure compatibility with your implement and input shaft. Replacement may require precise alignment during installation.
PTO Universal Drive Shaft Kit – 1310 Series
Best for: General-purpose PTO drives where a robust, cut-to-length solution is needed. The 1310-series joints are common in many farm and industrial applications, offering versatility for various implements.
Why picked: This kit is selected for its adaptability to multiple machines and its straightforward replacement approach when standard-length drives are not feasible.
Caution: Ensure the joint size and yoke match your existing PTO connections to avoid misfit or vibration issues. Custom cutting may be necessary for precise fitment.
Front Drive Shaft for Jeep Grand Cherokee
Best for: Jeep Grand Cherokee owners needing a front drive shaft replacement for 2002–2004 models with a 4.0L engine. This option emphasizes precise balance and corrosion-resistant coating for durability in on-road and light off-road use.
Why picked: The kit is manufactured to original standards to support stable handling and power transmission in crossover or daily driving scenarios, making it a practical option for vehicle owners seeking a straightforward upgrade.
Caution: Verify vehicle-specific reference numbers (65-9767, 659767, 52105884AA) to confirm fitment before purchase. Not intended for non-Jeep applications without adapter considerations.
Weasler CV Unequal Cross Bearing Kit
Best for: Implement systems using Weasler 2580 CV series cross and bearing kits, with unequal cross bearings for better torque handling in tight spaces.
Why picked: The kit supports upgrade flexibility, allowing interchangeability with E-, M-, or standard cross-bearing sets, which can simplify future maintenance and part sourcing.
Caution: Ensure compatibility with your specific Weasler drive shaft model and cross-bearing size. Mismatched kits can lead to improper fit or premature wear.
Buying Guide: CV Joint PTO Shaft Considerations
What to assess before buying
- Application and compatibility: Confirm the exact vehicle or equipment model, spline count, joint angle tolerance, and shaft length to avoid misfits.
- Joint type and angle: 80-degree CV joints suit sharper turns; some tasks may require standard CV or universal joints with specific angle limits.
- Material and durability: Look for high-quality steel and corrosion protection for outdoor or off-road use. Balance and vibration dampening reduce wear on other components.
- Installation and fit: Some kits require cutting to length or precise mounting hardware. Verify whether your setup needs additional hardware not included in the kit.
- Interchangeability: If you own multiple machines, prefer kits that allow cross-compatibility with E-, M-, or R-series cross bearings to simplify future replacements.
Choosing by scenario
- Farm work with irregular PTO angles: Prefer 80-degree CV joints and longer shafts with robust mounting.
- Older tractors with 2580 or similar tubes: Look for full CV/half-shaft combinations designed for 2580-series systems.
- Vehicle drive shafts (non-farm): Use vehicle-specific drive shafts with precise reference numbers and balanced construction.
Comparison snapshot
The following quick notes help with side-by-side decisions:
- Best all-around: PTO drive shaft kits with universal joints and 1310-series compatibility offer broad applicability for both farm equipment and light vehicles.
- Best for tractors needing wide-angle CV: 80-degree CV joints deliver smoother operation under sharp turning and rough terrain.
- Most vehicle-specific option: Front drive shafts for Jeeps and other models, designed to fit exact reference numbers and mounting arrangements.
Frequently asked questions
- What is a CV joint PTO shaft?
Answer: It is a power transfer shaft with a constant-velocity joint that allows for angular movement between the power source and the implement, reducing torque fluctuations and vibration. - How do I know which spline size I need?
Answer: Check the PTO input or implement yoke specifications; common sizes include 1-3/4″ or 1-3/8″ with matching splines such as 20-spline or 6-spline configurations. - Are all CV joints interchangeable?
Answer: Not always. Some kits are model-specific or series-specific (e.g., 2580 or 1310), so verify compatibility before purchasing. - What maintenance is needed for CV PTO shafts?
Answer: Regular inspection for wear, lubrication of cross bearings, and ensuring protective coatings remain intact to prevent corrosion and fatigue. - When should I replace a PTO shaft kit?
Answer: Replace if you notice excessive play, visible damage, unusual vibration, or compromised balance that affects machine operation. - Do these kits require professional installation?
Answer: Some installations can be DIY with proper tools, but others may require alignment, cutting, or torque specifications best handled by a professional.
