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.

### Torque Converter Replacement on a Massey Ferguson TE-20 Tractor

#### Tools Needed:
1. **Wrenches**: Metric and standard sizes (for bolts and nuts).
2. **Socket Set**: Including a ratchet and extension.
3. **Torque Wrench**: To ensure proper torque specifications.
4. **Pry Bar**: For leverage on stubborn components.
5. **Screwdrivers**: Flathead and Phillips.
6. **Pliers**: For clips and small components.
7. **Jack and Jack Stands**: To lift the tractor safely.
8. **Oil Drain Pan**: To catch any fluid.
9. **Torque Converter Replacement Kit**: Includes the new torque converter and any necessary seals or gaskets.
10. **Brake Cleaner**: For cleaning surfaces.
11. **Safety Goggles and Gloves**: For personal protection.

#### Safety Precautions:
1. **Wear Safety Gear**: Always wear goggles and gloves to protect against dirt and debris.
2. **Secure the Tractor**: Ensure the tractor is on a flat surface, engage the parking brake, and use wheel chocks.
3. **Disconnect Battery**: Remove the negative terminal to prevent accidental starts.
4. **Use Jack Stands**: Never rely solely on a hydraulic jack for support.

### Step-by-Step Procedure:

1. **Preparation**:
- Disconnect the battery.
- Drain the transmission fluid into an oil drain pan.

2. **Remove the Engine Cover**:
- Use the appropriate socket and wrench to remove any bolts securing the engine cover. Set it aside.

3. **Remove the Drive Belt**:
- Loosen the tension on the drive belt and remove it from the pulleys.

4. **Remove the Torque Converter**:
- Locate the torque converter’s mounting bolts. Use a socket to remove them.
- Carefully pry the torque converter away from the engine using a pry bar if it is stuck.

5. **Inspect and Clean**:
- Once removed, inspect the area for any damage or debris.
- Clean the mounting surfaces with brake cleaner to ensure a proper seal for the new converter.

6. **Install the New Torque Converter**:
- Position the new torque converter in place, aligning it with the engine mounting points.
- Gently push it into place, ensuring the splines engage properly.

7. **Secure the Torque Converter**:
- Install the mounting bolts and tighten them to the manufacturer’s torque specifications using a torque wrench.

8. **Reinstall the Drive Belt**:
- Place the drive belt back onto the pulleys, ensuring proper alignment.

9. **Reattach the Engine Cover**:
- Secure the engine cover back in place with the appropriate bolts.

10. **Refill Fluid**:
- Refill the transmission with the correct type and amount of fluid as specified in the manual.

11. **Reconnect Battery**:
- Reattach the negative battery terminal.

12. **Test the Installation**:
- Start the tractor and check for any leaks or abnormal noises. Test the torque converter by engaging the tractor in gear.

### Common Pitfalls to Avoid:
- **Incorrect Torque Specifications**: Always refer to the service manual for the correct torque settings to avoid damaging components.
- **Debris Left Behind**: Ensure that all surfaces are clean before installing the new torque converter to prevent leaks.
- **Misalignment**: Make sure the splines of the torque converter are correctly aligned with the engine to avoid premature failure.
- **Fluid Leaks**: Double-check all connections and seals after installation to prevent fluid leaks.

### Replacement Parts:
- Ensure you have a complete torque converter kit that includes any necessary gaskets and seals to ensure a proper fit and avoid leaks.

By following these steps and precautions, you can successfully replace the torque converter on a Massey Ferguson TE-20 tractor.
