Common uses:

Checking Crankshaft Roundness

• Roundness Measurement: Crankshaft journals must be perfectly round for smooth operation of engine components. A crankshaft gauge can check for deviations from roundness, ensuring that the crankshaft won’t cause excessive wear or vibration.
• Ovality Detection: If the journal becomes slightly oval due to wear, it could lead to inefficient power transmission or damage to the bearings. The gauge can identify such issues.

Taper Measurement

• Journal Taper: Over time or due to manufacturing issues, crankshaft journals might develop a taper, where the diameter changes along the length of the journal. The gauge is used to check for taper to prevent issues in engine performance and component alignment.

Measuring Crankshaft Run-out

• Run-out: Run-out refers to the amount of deviation or wobble of the crankshaft during rotation. This can be caused by manufacturing defects or wear. The crankshaft gauge helps detect excessive run-out, ensuring the crankshaft is straight and will operate smoothly within the engine.

Checking Crankshaft Wear

• Wear Assessment: Crankshaft gauges are used during maintenance to check for wear on the crankshaft after prolonged use in an engine. The gauge can detect any reduction in the journal diameter, ovality, or surface irregularities that might affect the crankshaft’s function.

Measuring Crankshaft Alignments

• Straightness: The crankshaft gauge ensures the overall straightness of the crankshaft, which is crucial for reducing vibrations and maintaining smooth engine operation. Misalignment can lead to increased friction, wear, or even engine failure.
• Crankshaft Twisting: The gauge can detect any twisting or distortion in the crankshaft that might impact the engine’s performance and cause operational inefficiencies.
