Fuel System/Aneroid CTM3274 (01JUL99) 40-58 Saran Liter Engines 060799 PN=303 ANEROID WORKSHOP ADJUSTMENT 1. Install a new aneroid on the injection pump. 2. Connect a regulated air pressure source to aneroid inlet and use a mercury manometer in preference to a gauge, as operating pressures are very low. 3. Note the pressure at which shut-off lever lifts off forward screw (B) and the pressure required to obtain full travel until rear screw (C) bottoms. -UN-08MAR95 4. Pressure specifications are: Lever lift-off . . . . . . . . . . . . . . . . . . . 76—102 mm Hg (3—4 in. Hg) 10—14 kPa (1.5—2.0 psi) CD30187 Lever at full travel . . . . . . . . . . . . 330—380 mm Hg (13—15 in.
Hg) 44—51 kPa (6.4—7.4 psi) NOTE: Lift-off pressure can be checked by inserting a shim of 0.05 mm (0.002 in.) thickness between lever and front screw; the shim will slip out as soon as the lever starts to move. 5. If lever travel requires more pressure than specified, lengthen the operating rod; if less pressure is required, shorten operating rod. 6. Once aneroid is set, repeat test to check adjustment. 7. Install injection pump on engine. IMPORTANT: During aneroid adjustment, do not touch the forward/rear screw, as these devices have been adjusted on the test stand. CD,3274,G40,37 -19-27APR92 40 58
