Performing a wheel alignment check on a Hitachi EX150LC-5 and EX160LC-5 excavator involves ensuring that the machine’s tracks are properly aligned and that the undercarriage components are in good condition. click here for more details on the download manual…..

Although excavators do not have wheels in the traditional sense like trucks, they do have tracks that need to be aligned correctly for optimal performance. Here’s a detailed guide on how to perform a track alignment check on these excavators, including descriptions of components involved.

### Components Involved

1. **Tracks**: The rubber or steel tracks that provide traction and mobility to the excavator.
2. **Track Rollers**: Support the weight of the excavator and allow the tracks to move smoothly.
3. **Idler**: The front component of the track system that helps guide the track.
4. **Sprocket**: The toothed wheel that engages the track and drives the excavator forward.
5. **Track Tensioner**: Adjusts the tension of the track to ensure proper contact and avoid slippage.
6. **Frame**: The main structure of the excavator that houses the engine and provides support for the undercarriage.

### Tools Required

– **Track Alignment Tool** (Laser level/Alignment tool)
– **Tape Measure**
– **Wrench Set** (for adjustments)
– **Hydraulic Jack** (if necessary)
– **Safety Gear** (gloves, goggles, hard hat)

### Step-by-Step Guide for Track Alignment Check

#### 1. **Preparation**

– **Ensure Safety**: Park the excavator on a flat, stable surface. Engage the parking brake and turn off the engine. Use wheel chocks if necessary.
– **Gather Tools**: Collect all tools and safety gear.

#### 2. **Inspect the Tracks**

– **Visual Inspection**: Check for any visible wear, damage, or debris on the tracks. Look for cracks, missing links, or uneven wear patterns.
– **Check Track Tension**: Use the track tension indicator (if equipped) or a tape measure to check the sagging of the track. Proper tension should allow for about 2-4 inches of deflection when pressed in the middle of the track between the rollers.

#### 3. **Alignment Check**

– **Use Track Alignment Tool**: Place your alignment tool or laser level on the ground parallel to the tracks.
– **Measure Alignment**: Measure the distance from the alignment tool to the track at both the front and rear of the track.
– **Front Measurement**: Take a measurement from the alignment tool to the front idler.
– **Rear Measurement**: Take a measurement from the alignment tool to the rear sprocket.
– **Compare Measurements**: The distance should be equal on both sides. If they differ, adjustments are needed.

#### 4. **Adjust Track Tension**

– **Loosen Track Tensioner**: If the tracks are too tight, locate the tensioner (usually found near the rear of the undercarriage). Use the appropriate wrench to loosen the tension.
– **Adjust Tension**: Use a hydraulic jack to raise the tensioner if necessary, or adjust the tensioning bolt to achieve proper tension.
– **Retighten**: Once the desired tension is achieved, retighten the bolts.

#### 5. **Adjust Track Alignment**

– **Track Adjustment**: If the alignment is off, you may need to adjust the idler or sprocket position.
– **Idler Adjustment**: Loosen the bolts holding the idler download Hitachi EX150LC 5 EX160LC 5 Excavator workshop manual and reposition it. Make sure it is centered on the track.
– **Sprocket Adjustment**: Similarly, check the sprocket for alignment. Slight adjustments may be necessary to ensure that it engages the track correctly.
– **Recheck Alignment**: After adjustments, re-measure the track alignment using the alignment tool to ensure that it is now equal on both sides.

#### 6. **Final Checks**

– **Rotate Tracks**: Manually rotate the tracks a few times to ensure smooth operation and check for any unusual noises or issues.
– **Reinspect**: Perform a final visual inspection of all components to ensure everything is in place and secure.
– **Document Findings**: Record any adjustments made for future reference.

### Conclusion

Regular track alignment checks are essential for the performance and longevity of the Hitachi EX150LC-5 and EX160LC-5 excavators. Properly aligned tracks reduce wear on the undercarriage components, improve fuel efficiency, and enhance overall machine performance. Always refer to the manufacturer’s manual for specific guidelines and torque specifications.
The throttle position sensor (TPS) is a crucial component in an internal combustion engine’s electronic control system. It plays a significant role in managing the air-fuel mixture that enters the engine, thereby directly influencing its performance, efficiency, and emissions. typically located on the throttle body, the TPS monitors the position of the throttle plate, which regulates the amount of air entering the engine.

As the driver presses the accelerator pedal, the throttle plate opens, allowing more air to flow into the engine. The TPS converts the mechanical position of the throttle plate into an electronic signal that is transmitted to the engine control unit (ECU). This signal provides real-time data about the throttle’s position, enabling the ecu to adjust fuel injection and ignition timing accordingly. This precise control is vital for optimizing engine performance across various driving conditions.

The TPS usually operates as a variable resistor, generating a voltage signal that corresponds to the angle of the throttle plate. If the TPS malfunctions, it can lead to various issues, such as erratic engine behavior, poor fuel economy, reduced acceleration, or even stalling. Common symptoms of a faulty TPS include a check engine light, hesitation during acceleration, and difficulty maintaining a steady speed. As such, regular diagnostics and maintenance of the throttle position sensor are essential for ensuring the smooth operation of modern vehicles.
