Static Procedure (Model VP-20 ONLY)
- Remove the timing plug on the injection pump head and rotate the engine to TDC. Mount dial Indicator and adapter (D84P-9000-D) to the injection pump head. See Fig 1
. Preload indicator about .01" (.25 mm) is indicated on the dial indicator.
- Rotate the engine clockwise until lowest value is displayed. Set the dial indicator on zero. Turn the engine clockwise until No. 1 cylinder is at TDC. Using TDC Aligning Pin (T84P-6400-A), hold the engine at TDC and check the measurement of the pump plunger with reference of the mileage on the timing belt.
- If the measurement is not correct, loosen pump and install Rotating Tool (T84P-9000-B). See Figure
& Figure
. Rotate the pump until the proper measurement is attained. Retighten the mounting bolts and nuts in the following sequence: nut on inside of front flange near engine, nut on outside of front flange, then rear bolts.
- Rotate the engine a few times and recheck specifications after setting engine on TDC. If the measurements are correct, reinstall injection pump timing plug.
