Adjustments MAINTENANCE AND LUBRICATION Oil Pump - 400 Engines 1. Before adjusting the oil pump, check engine idle RPM and carburetor adjustments in your owner's manual supplement. 2. Loosen the throttle cable jam nut and turn the adjuster in or out until there is 1/16″ - 1/8″ (.16 - .32 cm) throttle lever travel before the throttle slide starts to open. See your owner's manual supplement. 3. Place very slight pressure on the throttle lever until all freeplay is removed from the throttle cable (to the point where the carb slide is just starting to rise). 4. Lift the boot (1) up off the adjuster sleeve (2). 5. Remove the oil pump cover and loosen the cable adjuster locknut. 6. Adjust the oil pump cable until the marks align (3) when the throttle slide just begins to rise. 7. Tighten the locknut. 8. Recheck the adjustment. If it's 3 correct, slide the boot all the way down over the upper portion of the bottom nut (4) to ensure good sealing against water entry. 9. Reinstall the oil pump cover and gasket. 1 2 4 103
