Pressure Calibration Check
To perform this procedure, use Pressure Test Kit 32891.
1. Rotate the swivel head fully counterclockwise.
2. Clamp the tool head gently in a vise with the
handles upward.
3. Remove the RTV (98) and port plug (97).
4. Install the pressure gauge with the gauge adapter
into the port that the plug (97) was removed from.
5. Center a new test slug in the dies and pump the
handle. Note the pressure required to open the relief
valve (which produces an audible click).
6. Repeat Step 5 twice, for a total of three slugs.
The relief pressure for every slug should be
214 to 289 Bar (3100 to 4200 psi).
7. Evaluate every test slug with the Go/No Go gauge
as shown.
• If the test slug checkpoint does not fit into GO slot,
the pressure relief valve is set too low.
• If the test slug checkpoint fits into the NO GO slot,
the pressure relief valve is set too high.
• If the test slug checkpoint fits into the GO slot and
does not fit into the NO GO slot, the pressure
relief valve is set correctly.
