SMC106L worn bearing
Hi,
We are facing a problem on a compressor SMC106L. The crankshaft bearing was totally screwed. It has run for 6 years without problem. We replace the sleeve and it was worn again after 8 hours (see worn sleeve attached). We have made many tests on the oil system to be sure everything is working properly :
- Oil pressure at 65psi
- Pressure drop in filter at 5 psi
- Oil control working
- Oil cooler leak test is ok
- Thermostat, relay and solenoid valve on oil cooler are ok
- No unusual vibration on start-up
- All other parts seems fine
What else could have cause this issue?
