Gear ratio adjustment in a machine like the Kobelco SK115 or SK135 excavator is an important process that can affect how the machine performs. Here’s a simple explanation of what gear ratios are and how to adjust them, assuming you have little mechanical experience:

### Understanding Gear Ratios

1. **What is a Gear Ratio?**
– A gear ratio is the relationship between the number of teeth on two gears that are meshed together. It determines how many times one gear turns compared to another.
– For example, if Gear A has 10 teeth and Gear B has 20 teeth, Gear A will turn twice for every one turn of Gear B. This can affect speed and torque.

2. **Why Adjust Gear Ratios?**
– Adjusting gear ratios can help improve performance for different tasks. For instance, a higher gear ratio might be used for speed, while a lower ratio could provide more power for heavy lifting.

### Adjusting Gear Ratios on Kobelco SK115/SK135

1. **Gather Tools and Safety Gear:**
– You will need basic tools like wrenches, screwdrivers, and possibly a jack for lifting the machine.
– always wear safety gear such as gloves and safety glasses.

2. **Locate the Gearbox:**
– The gearbox is usually found near the tracks or under the machine. This is where the gear ratios are set.

3. **Consult the Manual:**
– Before making any adjustments, it’s crucial to consult the operator’s manual for your specific model. The manual will provide details on the gear ratio settings and any specific procedures.

4. **Identify Adjustment Points:**
– Look for adjustment points on the gearbox. These could be screws or bolts that hold the gears in place.

5. **Make Adjustments:**
– Depending on the design, you may need to either tighten or loosen these points.
– If you want to increase the gear ratio (for speed), you may adjust the settings to allow for a higher gear. If you want to decrease it (for more power), adjust it to a lower gear.

6. **Test the Machine:**
– After making adjustments, lower the machine back to the ground and test it. Try operating it at different speeds and loads to ensure it performs as expected.

7. **Recheck Adjustments:**
– After testing, recheck the adjustments to ensure everything is secure download Kobelco SK115 SK135 Parts workshop manual and correct.

8. **Keep Records:**
– It’s a good idea to keep track of the adjustments you’ve made. This will help you in the future if you need to revert or make further changes.

– regular maintenance and checks can also help ensure your gear ratios remain optimal over time.

By following these steps and understanding the basics, you should be able to adjust the gear ratios on a Kobelco SK115 or SK135 excavator effectively.
Keyless entry is an innovative Automotive technology that enhances convenience and security for vehicle users. This system allows drivers to unlock and start their vehicles without the need for a traditional mechanical key. Instead, it typically utilizes a key fob or smartphone equipped with RFID (Radio Frequency Identification) or Bluetooth technology. The key fob emits a signal that is detected by a receiver in the car when the user approaches, allowing the doors to unlock automatically.

In addition to unlocking the doors, many keyless entry systems are integrated with push-button start mechanisms. This feature allows drivers to start the engine simply by pressing a button, provided the key fob is inside the vehicle. This not only simplifies the process of entering and starting the car but also offers enhanced security features. For instance, the vehicle can be programmed to recognize only specific key fobs, reducing the risk of unauthorized access.

Moreover, keyless entry systems often come with additional functionalities such as remote locking and unlocking, trunk release, and even panic buttons, which can be activated in emergency situations. The technology has evolved to include smart features, such as proximity sensors that recognize when the driver is nearby, further streamlining the user experience. Overall, keyless entry represents a significant advancement in Automotive technology, combining ease of use with improved vehicle security.
