If you’ve ever needed to build or repair a custom PTO driveline, you know how important it is to have the right yoke for welding onto your shaft. This 12 series shaft weld yoke is designed to handle the mid-range power requirements of tractors running implements that need more beef than a 6 series but don’t require the heavy-duty capacity of a 14 or 35 series.
What You’re Getting
- 1-1/16 inch bearing cap diameter provides solid U-joint support for reliable power transfer
- 2-1/2 inch cross length matches standard 12 series specifications for proper component compatibility
- 3-3/8 inch center-to-end measurement allows for precise driveline geometry calculations
- 1 x 1-1/8 inch bore size accommodates rectangular shaft profiles for secure welded connections
- Quality Weasler construction means it’s built to handle the torque and vibration of agricultural use
Built for Real Farm Work
The 12 series is the sweet spot for many mid-sized tractors running implements like rotary cutters, hay equipment, and other PTO-driven machinery. You’ll find this yoke useful when building custom drivelines for specialty equipment or when repairing shafts that have seen better days. It’s designed to work with other 12 series components, so your universal joints and mating yokes will line up properly.
Made to Last
Weasler doesn’t mess around – their yokes are forged tough and machined to tight tolerances. The bearing surfaces are precisely machined to ensure smooth operation and long life under the constant speed changes and angles that come with real field work. This isn’t a hardware store part that’ll leave you stranded.
Installation Notes
Welding this yoke requires proper technique and equipment – the heat-affected zone needs to maintain strength without becoming brittle. Make sure your shaft dimensions match the bore size exactly, and consider having the welding done by someone experienced with PTO components. Proper phasing with your mating yoke prevents vibration that’ll shake your whole driveline apart.
