Rework Procedure
Four seals need to be replaced on each oil mist detector (OMD). The o-ring seal under the OMD flange will need to be replaced. The seal washers on the bottom of the detector head will need to be replaced. The large seal under the detector head will also need to be replaced.
Note: Do not remove or loosen the nut which positions the OMD flange.
Note: Refer to Image1.1.1 for OMD details.
Note: For C175 seal replacement only, the detectors behind the thermostat and fuel pump can be removed without removing other iron. The detector head should be removed first. This will allow the body to rotate for removal.
First remove any wires connected to the OMD.
To remove the OMD loosen the two bolts which secure the OMD flange to the block side cover.
Once the OMD has been removed loosen the two M6 screws under the OMD head unit. The OMD head will then be removable. Please use caution removing the screws from the OMD body as there are screw retainers which keep the screws in place.
When the two M6 screws have been removed replace the old seal washer with the 524-7006 washer then reinsert the screws into the body and screw retainers.
Replace the large seal on the bottom of the detector head then reinstall the head back onto the body. Tighten the M6 screws to 2 Nm or the washers may leak after installation.
Replace the o-ring on the OMD flange then reinstall the OMD. Tighten the two side cover bolts to the proper torque.
Connect all wires associated with the OMD. Repeat the procedure for the next OMD.
