1000ml Test Tube Caterpillar 1839303

The Test Tube visually confirms correct oil filling within track pins during service or assembly operations. It simulates the inner and outer cavities of a track pin, allowing operators to observe oil transfer behavior in real time. During testing, oil should flow from the simulated inner cavity to the outer cavity in sequence. If oil fills the first chamber and then stops without progressing to the second chamber, it indicates that the test and fill is not operating correctly and may require servicing or repair.Attributes:• Promotes accurate assessment of internal sealing surfaces.• Minimizes unexpected downtime through early leak detection.• Reduces risk of undercarriage failure caused by seal defects.• Markings provided at 80 percent, 85 percent, and 90 Percent fill.Applications: The Test Tube is mounted on the test and fill unit, where it visually confirms oil flow from inner to outer pin cavities, indicating correct filling, and simulates internal pin cavities and verifies correct oil distribution.
