I - Master Link

To adjust roller chain (A), loosen set screw (B) and slide sprocket (C) on drive gear shaft (D) until it is vertically in line with drive sprocket (E).

When installing chain, position chain clip (H) on master link (I) so the split end of the clip trails in direction of travel (arrow).

Adjust chain by loosening mounting screws and moving pump until chain is tight but can still be deflected by thumb pressure. Tighten pump mounting screws.

Turn flywheel until feeder crank moves approximately 90°. Check pump chain tension. If chain is tight at this position, loosen pump (F) and adjust chain until it is tight but can be deflected by thumb pressure. Turn flywheel until feeder crank moves another 90°.

Recheck chain tension and adjust, if necessary.
