The colloquial term "Ferguson 28" is sometimes used in Australia and New Zealand for later models of the TE-20 including the petrol TEA-20 and diesel TEF-20.[citation needed] "Ferguson 28" has never been an official tractor model designation. Initially the TE20 had the 'Continental' Z120 23HP engine, as did the Detroit-built TO20 introduced a year later. The 80 mm bore 'Standard' petrol engine was phased in in mid-1947 as the TEA-20, approximately 3,000 of the 20,500 tractors built to 31 December 1947 being TEA-20s. Subsequent to the introduction of the 85 mm bore TED-20 in April 1949, the petrol engine was also made with an 85 mm bore, which increased its power to just over 28 hp. The term "Fergie 28" refers to the nominal horsepower of the later range of tractors. To benefit from the reputation of the later models in the used tractor market, the 23HP TE-20 is often advertised simply as TE-20; only very rarely is it referred to in Australia as a "Ferguson 23". In North America the 'Standard' petrol-engined TEA-20s with the 85 mm bore were known and advertised as TE-2085s.

- **Understanding the Sway Bar Link**
- The sway bar link connects the tractor's rear axle to the chassis and helps control side-to-side movement. If it's worn or damaged, it can lead to instability while driving.

- **Tools Required**
- **Wrench Set (Metric and Standard)**
- Used to remove and tighten bolts and nuts. Having both metric and standard sizes ensures you can fit the correct size.
- **Socket Set**
- Offers a variety of socket sizes for easier access to bolts in tight spaces. A ratchet handle allows for efficient turning.
- **Pry Bar**
- Used to help maneuver parts into position if they are stuck or difficult to align.
- **Torque Wrench**
- Ensures that bolts are tightened to the manufacturer's specified torque, which prevents damage from over-tightening.
- **Jack and Jack Stands**
- To lift the tractor safely, allowing access to the sway bar link. Always use jack stands for safety when working under the tractor.
- **Safety Glasses**
- Protects your eyes from debris while working.
- **Gloves**
- Protects your hands from sharp edges and contaminants.

- **Replacement Parts**
- **Sway Bar Link**
- Inspect the old sway bar link for wear, cracks, or bending. If it shows signs of wear, a replacement is necessary to maintain stability.
- **Bushings**
- Rubber bushings may need replacement if they are cracked or deteriorated. These help reduce vibration and noise.

- **Step-by-Step Replacement Process**
- **Preparation**
- Park the tractor on a flat surface and engage the parking brake.
- Wear safety glasses and gloves.

- **Lifting the Tractor**
- Use the jack to lift the rear of the tractor.
- Place jack stands under the tractor to ensure it is stable and safe to work on.

- **Removing the Old Sway Bar Link**
- Locate the sway bar link near the rear axle and chassis.
- Use the wrench or socket set to remove the nuts securing the sway bar link on both ends.
- Carefully pull the old sway bar link out of its mounting points.

- **Installing the New Sway Bar Link**
- Position the new sway bar link in place.
- Hand-tighten the nuts onto the bolts to hold the link in position.
- Use the torque wrench to tighten the nuts to the manufacturer's specifications. This prevents over-tightening and potential damage.

- **Replacing Bushings (if necessary)**
- Remove the old bushings from the sway bar link mounting points.
- Push the new bushings into place, ensuring they fit snugly.

- **Final Steps**
- **Lower the Tractor**
- Carefully remove the jack stands and lower the tractor using the jack.

- **Test Drive**
- Take the tractor for a short test drive to ensure stability and check for any unusual noises.

- **Conclusion**
- Regular maintenance of the sway bar link is essential for safe tractor operation. If you encounter significant wear or damage, consult a professional for further assistance.
