Troubleshooting: Komatsu PC200-7 Track De-tracking
A common issue with tracked machinery is the track coming off the rollers and idlers (de-tracking). On a Komatsu PC200-7, this can often be caused by insufficient track tension, worn idler flange, or damaged track rollers or sprockets.
Detailed Solution:
1. Safety First: Park the machine on firm, level ground away from slopes. Lower the boom and bucket to the ground. Shut off the engine and engage the parking brake.
2. Inspect Components: Carefully inspect the idler (20Y-30-00321, 20Y3000321), track rollers (20Y-30-00016, 20Y3000016), carrier rollers (22U-30-00021, 22U3000021), and sprocket (20Y-27-11582, 20Y2711582) for wear or damage. Check the track shoe (20Y-32-11340, 20Y3211340) condition and the tightness of all track shoe bolts (20Y-32-11230, 20Y3211230).
3. Re-track the Chain: This often requires specialized tools and another machine (like a dozer or another excavator) to help lift the track and guide it back onto the rollers and idler. It's a dangerous procedure and should only be done by trained personnel.
4. Adjust Track Tension: Once re-tracked, use the grease fitting on the track adjuster cylinder to pump grease and extend the cylinder, increasing tension until the sag is within the specification found in the machine's service manual.
5. Identify Root Cause: If components are worn, they must be replaced to prevent repeat de-tracking. Growshine International can supply the necessary genuine Komatsu parts or quality aftermarket equivalents.
