15827A 1 Mariner BODY, FUEL PUMP

TIMING MARKS2. Remove the plug from the timing pin hole in fuel injection pump housing and install timing pin (1).
TIMING PIN INSTALLED
1. FT887 Timing Pin (Fabricated Tool).3. Remove bolts (2) and tachometer drive assembly (3) from the fuel injection pump camshaft.4. Remove the drive gear (4) from the fuel injection pump camshaft.
PUMP DRIVE GEAR (Typical Example)
2. Bolts (three). 3. Tachometer drive assembly. 4. Drive gear.5. Remove retaining screw (5), washer (6), and small outer camshaft gear or automatic timing advance (7) from the engine camshaft.
CAMSHAFT GEAR
5. Retaining screw. 6. Washer. 7. Small outer camshaft gear.
TIMING ADVANCE
5. Retaining screw. 6. Washer. 7. Automatic timing advance.6. Install puller (8), with spacer (10) over the shaft in the camshaft and spacer (9) on spacer (10) as shown and remove the gear from the camshaft.
REMOVING GEAR (Typical Example)
8. 1P2321 Puller. 9. 8S5579 Spacer. 10. 9S9155 Spacer.Install Camshaft Gear
1. Heat the gear to a temperature of approximately 400° F (204° C) before installing on the camshaft.
Do not heat the gear with a torch. Do not heat the gear to a temperature of more than 600° F (315° C). Heating the gear with a torch or to a temperature of more than 600° F (315° C) may cause the two drive dowels for the timing gear to loosen and come out of the gear.
TIMING MARKS2. Align slot in gear hub with the pin in the camshaft. Install the gear on the camshaft with timing mark on gear aligned with timing mark on crankshaft gear. Be sure the gear is completely seated against the shoulder of the camshaft.
Do not drive the gear on the camshaft. Serious damage can result to camshaft or camshaft thrust pin.
3. Align holes in small gear with dowels in large gear and install the small gear.4. Align pin (11) in washer (6) with hole (12) in camshaft and install washer (6).
INSTALLING WASHER (Camshaft Gear)
6. Washer. 11. Pin. 12. Hole.
INSTALLING WASHER (Timing Advance)
6. Washer. 11. Pin. 12. Hole.5. Install retaining screw (5) and tighten to 108 36 lb. in. (124.5 41.5 cm.kg). Stake screw (5) in two places.
Stake retaining screw (5) carefully. Heavy blows on washer or retaining screw can force the shaft extension too far into the camshaft and eliminate all end clearance.
STAKING SCREW (Camshaft Gear)
5. Retaining screw.
STAKING SCREW (Timing Advance)
5. Retaining screw.6. After retaining screw (5) is staked, the gear requires .003 to .027 in. (0.08 to 0.69 mm) end clearance to prevent binding against the washer, camshaft end, or camshaft gear.7. Put timing plate (14) on the engine and thread bolt (13) into the timing gear.
TIMING PLATE INSTALLED (Typical Example)
13. Bolt. 14. 5P950 Timing Plate.8. Install drive gear (4) on the fuel injection pump camshaft with the holes in the position shown and the part number facing out. To be able to advance the timing adjustment without removing the front cover, position gear (4) in the direction of the arrow so the bolt holes in the fuel injection pump camshaft are off center as shown. The bolts must thread freely into the holes in the fuel injection pump camshaft.
GEAR INSTALLED
4. Drive gear.9. Install tachometer drive assembly (3) and tighten finger tight.
PUMP DRIVE GEAR INSTALLED
2. Bolts (three). 3. Tachometer drive assembly. 4. Pump drive gear.10. Install bolts (2) and tighten the bolts to 32 5 lb. ft. (4.4 0.7 mkg). Tighten the tachometer drive assembly (3) to 50 10 lb.ft. (6.9 1.4 mkg).11. Remove the timing pin from the fuel injection pump housing and install the plug in the timing hole.
