MDC Control Assembly
Ensure you install dowel pins (D300) in housing before installing control.
The pump will lose control, causing a potentially hazardous situation.
If a feedback pin comes off during operation, ensure the feedback pin is properly torqued before
continuing with reassembly.
1. Install a new gasket (D150).
2. If you removed screen (D084), install a new one with the mesh facing outward.
3. Install retaining ring (D098).
