5.9 Connecting Rod Bearings Inspection
Every 2000 hours of running, the Connecting Rod bearings should be inspected and replaced if
necessary. To inspect the Needle Bearing (smaller), remove the Connecting Rod assembly – see
Section 7.11, inspect the Wrist Pin outer diameter for deformation, if no bumps or dents are
present, insert the Wrist Pin through the needle bearing and rotate while holding the Connecting
Rod still. Notable bumpiness, roughness, knocking, or resistance to rotation would indicate this
bearing needs to be replaced. If the Wrist Pin outer diameter contains dents or bumps, replace both
the Wrist Pin and Needle Bearing. To inspect the Ball Bearing (larger), rotate the inner race of the
bearing by hand while holding the Connecting Rod still. Like before, notable bumpiness, roughness,
knocking, or resistance to rotation would indicate this bearing needs to be replaced.
Note: if bearings are not being replaced, re-pack with (RIX P/N 45-110) Polyurea grease before
installation – see Section 7.11.
5.10 Instrument Calibration
Control instruments should be verified for accuracy annually. Pressure gauges, switches, and relief
valves can be bench tested on a hydro fixture to confirm the accuracy of each device. Use only
deionized water for these tests.
