When replacing the 318343 compressor housing, verify the V-band clamp size and profile against your existing turbine housing to ensure a secure seal. Check O-ring material compatibility with your engine's oil and coolant temperatures, confirming the rating matches the operating conditions of the Komatsu D155 or D355 application. Confirm the compressor wheel nut thread direction and tightening torque per the manufacturer's service manual for the specific S500 configuration.
