How do I remove my 2 Series NOP Trochoid pump from the electric motor?
Only 2 screws need to be removed, and the pump will slide out of the motor hosing flange. If you look closely at the M8 cap screw there are 2 that are painted the same as the pump and 2 that are not as in a in a X pattern. The 2 that are painted sandwich the pump together and was painted as the pump was manufactured. The other 2 opposing cap screws attach the pump to the motor and are plain black oxide color. Removing just the 2 plain black oxide color screws is all that is needed. If uncertain slightly loosen 2 opposing screws and see if the pump will separate from the motor flange. If not, retighten and try the other opposing 2, and by twisting them back and forth the pump should pull straight off the motor ** A few ways to prolong the life of the Nippon Oil Pump is to have a regular preventive maintenance program for the machine. A routine to change & replace the fluids and filters will significantly increase the life of the Nippon Oil Pump. Unfortunately I have seen OEM manufacture
