I am working on a comp for a lowboy.
The comp model number is coplandmatic
There is a device about 1/3rd the way up the crankcase that is screwed into the comp.
It looks like a plug with a screw head in the middle.
in other words the plug is screwed into the comp and the screw is threaded into the plug.
When I backed out the screw I see what looks like a rubber plug or something black at the base of the threads.
The plug is very tight and I do mpt want to force it until I know what it is.
I want to change / check the oil level and this looks like the best place to drain old oil. I dont see a plug anywhere at the base of the comp.
Does anyone know what this device is before i take it out??
