Cylinder Liner Gauge Measurement Procedure
1. Zero Calibration
- Step 1: Insert the zero-setting tool to depress the bore gauge thimble
- Step 2: Rotate the dial until the main needle aligns with “0”
- Verification: Confirm zero point is accurately set before measurement
2. Height Adjustment
- Optimal Position: Set measurement point 5mm below piston ring edge
- Adjustment Method: Turn the nut on the screw eye to fine-tune probe height
3. Measurement Process
- Preparation:
- Thoroughly clean cylinder liner surface
- Clear scavenge ports of debris
- Positioning:
- Place measuring tool according to guide marks
- Ensure bore gauge remains perpendicular to liner surface
- Reading: Record measurements at both front and rear reference points
4. Safety Protocol
Prior to measurement, implement LOCKOUT/TAGOUT:
- System Shutdown:
- Disable start mechanism
- Secure starting air valve CLOSED
- Fluid Isolation:
- Shut off fuel supply
- Drain lubricating oil system
- Mechanical Safeguards:
- Engage gear turning device OFF
- Block cooling water circulation
- Lock turbocharger rotor
