Engine case plug?...
« on: April 07, 2020, 05:40:04 AM »
I have the engine on a stand and cranking it to build UP oil pressure before starting it up. There is a plug on the alternatorside in the bottomhalf of the crankcase that keeps poping out as the engine builds up oil pressure... Do i miss something? Wat is suposed to keep this plug in place? It a cb 400

The alternator cover needs to be fitted

The plug is inside about 15 mm, so putting on de cover does not prevent the plug of popping out. Stays a mystery to me...
