Proper track tension adjustment is critical for maintaining the performance, safety, and longevity of Komatsu excavators, such as the PC200-8, PC360LC-11, and PC490LC-11. Incorrect track tension can lead to premature wear, track derailment, or reduced stability, increasing downtime and repair costs. Komatsu service and operator manuals provide OEM-compliant procedures for adjusting track tension, ensuring optimal operation. PDF manuals from Manualskart.com offer instant access, searchability, and affordability, making them ideal for this task. This guide, provides a step-by-step process for adjusting track tension on Komatsu excavators, based on standard procedures found in Komatsu manuals. Keywords like “Komatsu track tension adjustment” and “excavator track maintenance” are integrated for discoverability.
Why Track Tension Adjustment Is Important
Track tension affects the excavator’s undercarriage, traction, and stability. Proper adjustment, as outlined in Komatsu manuals, ensures:
- Reduced Wear: Prevents excessive strain on tracks, rollers, and sprockets.
- Improved Stability: Maintains safe operation on uneven terrain.
- Enhanced Traction: Optimizes digging and maneuvering performance.
- Minimized Downtime: Avoids track derailment or component failure.
- OEM Compliance: Aligns with manufacturer standards, preserving warranties.
PDF manuals from Manualskart.com are affordable ($10–$50 vs. $100–$2,900 for printed manuals), instantly downloadable, and searchable, enabling efficient and accurate track tension adjustments.

Step-by-Step Guide to Komatsu Excavator Track Tension Adjustment
This guide is based on standard procedures from Komatsu operator and service manuals, such as those for the PC200-8, PC360LC-11, and PC490LC-11, and reflects industry-standard practices for undercarriage maintenance.
1. Identify the Excavator Model and Manual
-
Process:
- Locate the excavator’s model and serial number on the nameplate (e.g., chassis, cab, or counterweight) or in documentation (e.g., Komatsu PC200-8, PIN KMTPC12345678901).
- Download the matching operator or service manual from Manualskart.com by searching the model (e.g., “Komatsu PC360LC-11 operator manual”) and verifying serial number compatibility.
- Purpose: Ensures the correct track tension adjustment procedure for your specific model, as specifications vary.
- Example: For a Komatsu PC200-8, download the operator manual from Manualskart.com to find track tension guidelines.
- Pro Tip: Contact manualskart@gmail.com with the serial number if the manual isn’t listed.
2. Locate Track Tension Adjustment Procedure
-
Process:
- Open the PDF manual in Adobe Reader (get.adobe.com/reader).
- Use Ctrl+F to search for “track tension,” “undercarriage maintenance,” or “track adjustment.”
- Find the section detailing the adjustment procedure, typically in the maintenance or undercarriage section of the operator or service manual.
-
Key Information:
- Location of the track adjuster (grease fitting and valve).
- Recommended tension measurement (e.g., track sag distance).
- Tools and safety precautions required.
- Example: The Komatsu PC360LC-11 operator manual specifies the track tension procedure under “Maintenance,” including a target sag of 320–340 mm for standard tracks.
- Pro Tip: Bookmark the track tension section in the PDF for quick reference during adjustments.
3. Gather Tools and Materials
-
Tools Needed (per Komatsu manuals):
- Grease gun (manual or pneumatic) for injecting grease.
- Wrench (e.g., 19mm or 24mm) for the adjuster valve.
- Measuring tape or ruler for checking track sag.
- Pry bar or wooden block for lifting the track.
- Personal protective equipment (PPE) like gloves and safety glasses.
-
Materials Needed:
- OEM-specified grease (e.g., lithium-based grease, as listed in the manual).
- Cleaning rags for removing dirt or old grease.
- Example: The Komatsu PC200-8 manual recommends a high-pressure grease gun and NLGI No. 2 grease for track adjustments.
- Pro Tip: Use the parts catalog from Manualskart.com to order OEM grease or replacement adjuster components if needed.
4. Prepare the Excavator and Work Area
-
Process:
- Park the excavator on a flat, stable surface to ensure accurate measurements.
- Search the manual for “safety precautions” or “track adjustment preparation.”
- Follow instructions to:
- Lower all attachments (e.g., bucket) to the ground.
- Engage the parking brake and turn off the engine.
- Depressurize the hydraulic system to prevent accidental movement.
- Clean the undercarriage to remove dirt or debris around the track adjuster.
-
Safety Protocols:
- Wear PPE to protect against grease or debris.
- Ensure bystanders are clear of the work area.
- Avoid standing directly behind the track adjuster valve during grease release.
- Example: The Komatsu PC490LC-11 manual mandates cleaning the track frame to access the grease fitting safely.
- Pro Tip: Place a tarp under the excavator to catch grease spills, as suggested in some manuals.
5. Measure Current Track Tension
-
Process:
- Search the manual for “track tension measurement” or “track sag.”
- Lift the track slightly using a pry bar or by rotating the track to create slack.
- Measure the sag (distance between the track and the lowest roller) at the midpoint between the idler and sprocket.
- Compare the measurement to the manual’s recommended sag range (e.g., 320–340 mm for a Komatsu PC200-8).
-
Tension Guidelines (per Komatsu manuals):
- Too Loose: Excessive sag (e.g., >340 mm) indicates the track needs tightening.
- Too Tight: Minimal sag (e.g., <320 mm) indicates the track needs loosening.
- Example: The Komatsu PC360LC-11 manual specifies a sag of 320–340 mm for standard tracks, or 270–300 mm for swamp tracks.
- Pro Tip: Take multiple measurements to ensure accuracy, as uneven ground can skew results.
6. Adjust Track Tension
-
Process:
- Locate the track adjuster grease fitting and relief valve on the track frame (refer to the manual’s diagram).
-
To Tighten:
- Attach the grease gun to the fitting.
- Pump grease slowly until the track sag reaches the manual’s specified range (e.g., 320–340 mm).
- Stop pumping if resistance increases significantly to avoid over-pressurizing.
-
To Loosen:
- Loosen the relief valve slightly (e.g., 1–2 turns) using a wrench, allowing grease to escape.
- Release grease slowly until the sag reaches the specified range.
- Tighten the relief valve securely after adjustment.
- Re-measure the sag to confirm it matches the manual’s specification.
- Example: The Komatsu PC200-8 manual instructs pumping grease until the sag is 320–340 mm, then tightening the relief valve to 98 Nm.
- Pro Tip: Release grease in a controlled manner into a catch pan to avoid environmental contamination.
7. Verify and Test the Adjustment
-
Process:
- Search the manual for “track tension verification” or “post-adjustment checks.”
- Rotate the track forward and backward 1–2 times to settle the tension.
- Re-measure the sag to ensure it remains within the specified range.
- Start the excavator and test track movement on flat ground, checking for smooth operation and no derailment.
- Inspect the adjuster valve for leaks or damage.
- Example: The Komatsu PC490LC-11 manual recommends running the excavator slowly for 10 meters to confirm proper track tension.
- Pro Tip: Mark the adjusted position with a paint pen for future reference, as suggested in some manuals.
8. Document and Schedule Regular Checks
-
Process:
- Record the adjustment details (e.g., date, sag measurement, grease added) in a maintenance log.
- Follow the manual’s maintenance schedule (e.g., check track tension every 50 hours or weekly).
- Save the PDF manual for future adjustments.
- Example: The Komatsu PC360LC-11 manual suggests inspecting track tension every 50 hours or after operating in muddy conditions.
- Pro Tip: Save the PDF on a tablet or cloud drive for on-site access, compatible with Komatsu workflows.
