Fig. 1-Timing MarkUse JD-281 or JDE-81-1 Flywheel Turning Tool to position number one piston at top dead center. When the timing pin is inserted in the hole in the flywheel and the timing mark (A, Fig. 1) is visible on the injection pump governor weight retainer, the number one piston is at top dead center on the compression stroke.3-179D Engine (ROTO-DIESEL Fuel Injection Pump)
Fuel Injection Pump Only
Escaping diesel fuel under pressure can have sufficient force to penetrate the skin causing serious personal injury.If injured by escaping fuel, see a doctor at once. Serious infection or reaction can develop if proper medical treatment is not administered immediatetly.
Fig. 2-Loosen Injection Lines at NozzlesTo relieve high pressure in the fuel system, slightly loosen fuel injection line connections at each injection nozzle with two wrenches (Fig. 2).
Fig. 3-ROTO-DIESEL Fuel Injection Pump RemovalDisconnect throttle linkage (B, Fig. 3) and electric shut-off wire (C).Disconnect fuel return line (A) and fuel supply line (D). IMPORTANT: When removing injection lines, DO NOT turn pump outlet fittings. Turning these fittings may damage pump internally.Disconnect injection lines (E).Close all openings with caps and plugs.Remove injection pump gear cover from timing cover.Remove drive gear attaching nut from injection pump shaft and spring washer.
