Step 1 Advance Adjusting Tool: Threading tool onto the advance end plug Notes:


Step 2 Advance Adjusting Tool: Lightly clamping the Light Load Advance Piston with the Advance adjusting Tool Notes:

Rev 9/15





Pump Settings: Following Pump Service

22. Step 3 Advance Adjusting Tool: Screwing tool into the Speed Advance Plug Notes:


Step 4 Advance Adjusting Tool: Clamping the Light Load Advance Piston in place Notes:


Step 5 Advance Adjusting Tool: Moving the speed advance plug in the light load advance piston to set speed advance—Pump running for Speed Advance Setting, pump not running for final “trimming” of light load advance on T2 pumps. Notes:

Rev 9/15






Step 6 Advance Adjusting Tool: Tool removal 1. Loosen Part C 2. Unscrew Part D from speed advance plug 3. Loosen Part B 4. Unscrew Part A from advance plug assembly 5. Using the end cap at low pump RPM’s bleed

air from the advance and tightened the end cap to the proper torque.

Notes:


1º of speed advance set Notes:


8. Roller to Roller setting — If set properly during assembly should not need to be adjusted. If “small” adjustment needs to be made, both RR adjusting screws need to be adjusted the same.
