0308051 EVINRUDE RETAINER,Idle screw

start by: a) separation of governor from fuel injection pump housing1. Remove the cover (16) from rack centering pin. Move the rack to the fuel "OFF" position, and push in on the centering pin (15). Install the cover (16) as shown to keep the centering pin in position during disassembly and assembly of injection pump housing. 2. Move the rack toward the fuel "ON" position until the slot in rack (13) is against the rack centering pin (15). The rack is now in the "CENTER" position.
Do not try to remove the fuel injection pumps if the rack is not in "CENTER" position.
3. Remove the fuel injection pumps as follows: a) Remove the caps and felt washer (1).b) Install wrench (A), and remove the bushing (2) from housing. c) Install extractor (B).d) Remove the bushing (2) and wrench (A).e) Remove the seal (3).f) Lift the fuel injection pump up and out of housing.g) Remove the spacer (9). Keep the spacer (9) together with its respective fuel injection pump. Put identification on the pumps and spacers as to their location in the pump housing.4. Disassemble the fuel injection pumps as follows: a) Remove the ring (7), bonnet (4), check valve (6), and spring (5) from barrel (8).b) Remove the plunger assembly (11), washer (12), and spring (10) from barrel (8).
Be very careful when disassembling and assembling the fuel injection pumps to prevent damage to the plunger surfaces. The barrel and plunger assemblies are fitted together, and must not be used with other barrels or plunger assemblies.
5. Remove the rack centering pin, spring, and cover. 6. Remove the rack (13), and lifters (14). Put identification on the lifters as to their location in the pump housing. Keep the lifters with their respective pumps and spacers. 7. Remove the bolt, lock, and plate (17) from the camshaft. Remove the spring and gear assembly (18).8. Remove the camshaft (20) from pump housing.9. Remove the rack bearings (19) from housing. 10. Use tool setup (C) to remove the camshaft bearings from the fuel injection pump housing.Assemble Fuel Injection Pump Housing
1. Use tool group (D) to install the rack bearing in the accessory drive housing end of injection pump housing.2. Install the rack bearing in governor end of housing using tool setup (E). The bearing must be installed .195 .005 in. (4.95 0.13 mm) below outside face of pump housing.3. Use tool group (C) to install the camshaft bearings in housing. Make sure the oil holes in bearings are in alignment with oil holes in pump housing. 4. Put clean engine oil on the camshaft bearings. Install the camshaft (1) in pump housing. 5. Install the gear (3), spring, plate, lock, and bolt (2) on the camshaft.6. Put clean engine oil on lobes of camshaft. 7. Install the lifters (4) in their respective positions in pump housing. Install the spacers in their correct locations in housing. If new lifters are to be installed, it will be necessary to check the timing dimension for the fuel injection pumps. See FUEL PUMP TIMING DIMENSION SETTING - OFF ENGINE in TESTING AND ADJUSTING.8. Put clean fuel oil on the rack, and install it in the pump housing. Move the rack to the fuel "OFF" position. Install the rack centering spring and pin. Push in on pin, and install the cover to hold centering pin in position during assembly of injection pump housing.9. Push the rack to the fuel "ON" position until rack is against the rack centering pin. The rack is now in the "CENTER" position.10. Assemble the fuel injection pumps as follows: a) Put clean fuel oil on all pump parts.b) Install the spring (8), plunger (7), and washer (6) in barrel (9).c) Install the spring (12), check valve (11), bonnet (13), and ring (10) on the barrel.
Do not try to install the fuel injection pumps if the rack is not in "CENTER" position.
11. Install the fuel injection pumps as follows: a) Turn the camshaft until lobe of camshaft is down for the pump being installed.b) Install extractor (B) on the pump. Put the notches in bonnet and barrel in alignment. Put the notch in plunger gear 180° away from the notches in bonnet and barrel.c) Put the pump into position in housing so the notches in bonnet and barrel are in alignment with dowels in housing, and the notch in gear is in alignment with pin (5) in the lifter.
Do not use force to put pump into position. If the notches in barrel, bonnet, and gear are not in correct alignment, damage to pin (5) may result. If the pump is correctly installed, the distance from bonnet to top of housing (with the pump spring not in compression) will be about .5 in. (12 mm) as shown.
d) Install the seal, bushing, and wrench (A) on the pump.e) Push down on extractor (B), and tighten the bushing by hand (finger tight only) using wrench (A) until bushing is below top face of housing. If the bushing can not be installed this far by hand, remove it. Remove the pump. Put the notches in pump in correct alignment, and install the pump again. If plunger gears are not in correct alignment respective to the rack full rack travel will not be possible.f) Tighten the bushing to 150 10 lb.ft. (20.7 1.4 mkg). Install the felt washer and the protection caps.12. Loosen the bolt in centering pin cover. Put the cover in position, and tighten bolt.end by: a) connection of governor to fuel injection pump housing
