Compression testing can also reveal early signs of wear. A drop in compression indicates potential issues with the cylinder or piston.
How It Relates to Other Metrics: Early detection directly impacts equipment downtime. By catching problems early, you can schedule repairs proactively, minimizing unplanned downtime and keeping your operation running smoothly.
Personal Story and Data:
I learned this the hard way. I had a Stihl MS 462 with a US Chrome cylinder that I used extensively for felling large trees. I was so focused on production that I neglected regular inspections. One day, the chainsaw started losing power, and I noticed excessive vibration. Upon inspection, I found a deep score in the cylinder wall. The damage was so severe that the cylinder needed to be replaced, resulting in a $500 repair bill and three days of downtime.
After that experience, I implemented a regular inspection schedule. Every 50 hours of use, I visually inspect the cylinder and perform a compression test. This simple practice has saved me hundreds of dollars and prevented numerous unexpected breakdowns.
Example:
Let’s say you track your inspections and find that cylinders inspected every 50 hours last 20% longer than those inspected every 100 hours. This data justifies the time spent on regular inspections.
Actionable Insight:
Create a maintenance checklist that includes regular cylinder inspections. Schedule these inspections in your calendar and stick to the schedule. Use a borescope for a more thorough inspection of the cylinder walls.
Relevant Metrics:
