Dashpot: Testing and Inspection

Dashpot Test (Diaphragm)

1.

Check vacuum hose for leaks, blockage, kinks, and proper fit.

2.

Connect a hand-held vacuum pump to the dashpot diaphragm. Apply vacuum and observe dashpot linkage. The diaphragm assembly should hold
vacuum and linkage should move freely. If not, replace the dashpot diaphragm assembly.

Dashpot Test (Vacuum Valve)

3.

Connect a hand-held vacuum pump to the "DASHPOT" side of the vacuum check-valve. Apply vacuum and observe gauge. Vacuum should bleed
off slowly. If vacuum check-valve holds vacuum or bleeds off too quickly, replace the vacuum check-valve.
