Information:
Fuel Filter Group
(1) Remove clips (1) and (2). Remove tube assembly (3) and elbow (4) from the fuel transfer pump on the replacement engine. Installation of new line is shown in Fuel Lines Group, Page 8.Fuel Tank Group
(1) Remove the fuel tank from the machine; see the Service Manual. (2) Fabricate boss (1) to the dimensions shown. Make 1/8" - 27 NPTF threads in one end. (3) Drill a 20.0 mm Ø (0.78" Ø) hole (A) through the bottom of the tank as shown. (4) Put boss (1) in hole (A) with the threaded end extending below the bottom of the full tank as shown. Make a 3.0 mm (0.12") fillet weld all around the boss.(5) Clean and install the fuel tank; see the Service Manual.Fuel Lines Group
(1) Remove fuel inlet hose (1) and tube assembly (2) from tube (A). (2) Install 307946 Elbow (3) and a 3J7354 Seal in the fuel transfer pump. Install 2V4869 Fitting (4) on elbow (3). Cut a 360.0 mm (14.17") length of 5P1465 Hose (5), and connect it to fitting (4) and tube assembly (A) with the former clamps.(3) Install 6D238 Valve Assembly (7) in the boss installed in the fuel tank (see Step 4, Page 7). Fasten 5G5681 Tube (8) to valve assembly (7). Use L2072 Clamp (9) to hold the other end of tube (8) in position. Install clamp (9) under bolt (10).(4) Install 307941 Elbow (11) and a 3J7354 Seal in the fuel return port of the fuel injection pump housing. Install 2V4869 Fitting (12) on elbow (11).(5) Cut a 520.0 mm (20.47") length of 5P1465 Hose (13), and connect it to fitting (12) and tube (8) with a 1P4278 Clamp (14). An optional step to the above procedure is to connect a 60.0 mm (2.36") length of 5P189 Tube to valve assembly (7). Cut a 2000.0 mm (78.75") length of 5P6442 Hose and connect it to 2V4869 Fitting (12) and to the 5P189 Tube with a 1P4278 Clamp. Tie the hose to the machine to prevent damage to the hose.Electrical System
(1) For all machines, connect the alternator wire of the harness to the alternator.(2) For machines 80U1-80U6734, remove the original voltage regulator. Put tape over the wire connection to the wiring harness so it will be out of the way. The alternator for this engine has a built in voltage regulator so the original voltage regulator is not needed for the electrical system.Flywheel Group (For Replacement of 7N9437, 1W163 or 2W7488 Engine Arrangements)
(1) Remove the flywheel from the new replacement engine.(2) Install a new 7W2290 Flywheel Assembly, and fasten it to the crankshaft with four T489 Bolts. See the Service Manual for the procedure and the bolt torque. If necessary, use of the former flywheel from the engine being replaced is acceptable.Installation Of Ether Starting Aid Group
The ether starting aid is no longer a required component of direct injection engine arrangements.(1) If the machine is equipped with an ether starting aid group, its reuse is optional. To reuse,
(1) Remove clips (1) and (2). Remove tube assembly (3) and elbow (4) from the fuel transfer pump on the replacement engine. Installation of new line is shown in Fuel Lines Group, Page 8.Fuel Tank Group
