21400 Meyer Ground Wire Lock Washer Internal External Tooth 5/16"

A New Meyer Pump Ground Lock Washer # 21400.

This lock washer has external and internal teeth. When installing the lock washer onto a Meyer pump, it should be tightened enough that it digs into the paint a bit for sufficient grounding. It is placed onto bolt 15102 and between the cable terminal and the base of the pump.

This applies to most Meyer pumps.
