Information:
These fuel heater groups raise the temperature of the diesel fuel before it goes to the engine so it will flow freely in cold temperatures. Engine jacket water is used to heat the fuel in the heater. These groups are installed in similar procedures for all machines. See the instruction that follows for the correct installation procedures. Use pipe thread sealant on all pipe thread connections.3T1356 Heater Group (D8L)
(1) Drain the coolant from the radiator, and drain the fuel from the fuel tank. Disconnect heater hoses (1) and (2) from the heater. Install 8T2270 Tees (3), (4) and (5), as shown, where hoses (1) and (2) were removed. Connect hoses (1) and (2) to tees (3) and (5). Install 6J7366 cap (6) on tee (4). (2) Remove fuel filter (7) and stud (8). Put 9S3263 Thread Lock on 8N2101 Stud (9) and install stud (9) where stud (8) was removed. Install 8N9730 Fuel Heater (10) and an 8N2301 Seal on stud (9) with 8N2100 Connector (11). Put thread lock on connector (11). Tighten connector (11) 3/4 turn (270°) after it makes contact with heater (10). Install fuel filter (7) on connector (11). Connect 4V3410 Hose Assemblies (12) and (13) to tees (3) and (5); use thread lock on the threads. Connect hoses (12) and (13) to fuel heater (10) as shown, with two 5D1026 Clamps.3T6833 Fuel Heater (D8L)
(1) Drain the coolant from the radiator, and drain the fuel from the fuel tank. Remove cover (1) and plug (2); these parts will not be needed again. Install 6T6 Cover (3) and a 4N790 Gasket where cover (1) was removed; use the former hardware. Install 5P7747 Valve Assembly (4) and 307964 Elbow (5) in cover (3). Install 6B4661 Bushing (6), 9N3666 Valve Assembly (7) and 17004 Connector (8) where plug (2) was removed. (2) Connect 3T7673 Hose Assembly (9) to valve (7); connect 3T9872 Hose Assembly (10) to elbow (5). Put hoses (9) and (10) in position under the radiator and along the frame left rail. Fasten hoses (9) and (10) to existing bosses, bolts or brackets with 5D0718 Clips (11), S509 Bolts and 5M2894 Washers. Fasten hose (10) to the radiator guard with 9M4972 Clip (12), an S509 Bolt and 5M2894 Washer. (3) Remove fuel filter (13) and stud (14). Install 8N2101 Stud (15) with 9S3263 Thread Lock where stud (14) was removed. Install 8N9730 Fuel Heater (16) and a 8N2301 Seal on stud (15) with 8N2100 Connector (17); turn the connector 3/4 turn (270°) after it makes contact with the fuel heater. Install fuel filter (13). Connect hoses (9) and (10) to fuel heater (16) with two 5D1026 Clamps.6T1863 Heater Group (D9L)
(1) Install two 62325 Elbows (1) and (2) in 8N9593 Heater (3). Fasten heater (3) to an existing boss on the frame with a 6V2855 Grommet, 6V2853 and 6V2854 Clips, two S1591 Bolts and 5P1075 Washers. Disconnect heater
