Each shut-off group has the parts needed for one engine. Only one of the control groups given in the chart will be needed for each engine, and the control group used will be according to the rated speed of the engine. The control group, solenoid valve group and/or air control valve group must be ordered separately because they are not part of the shut-off group. For System Operation and Troubleshooting information for hydra-mechanical shut-off, see Service Manual FORM SEBR0511.Reconditioning Of Engine Oil Pump And Installation Of The Control Group
(1) Disconnect the engine starting system and shut off the fuel supply. Installation of the hydra-mechanical shut-off group will be made easier if the intake manifold for the right side of the engine is removed.(2) Some engine oil pumps must have parts removed and new parts installed. See the following four illustrations for the engine serial numbers and parts to be removed: Remove manifold assembly (1) and shaft (2). Remove cover assembly (3) and shaft (4). Remove cover assembly (5) and shaft (6). Remove plate (7) and cover assembly (8). (3) Install a new shaft (9) as a replacement for shaft (2), (4) or (6) according to the model and serial numbers that follow:D379 68B2540 - 68B5182; install a 5N3796 Shaft (9).D398 66B3561 - 66B4180; install a 5N3796 Shaft (9).D398 66B4181 - 66B6058; install a 5N3800 Shaft (9).D399 35B688 - 35B1274; install a 5N3800 Shaft (9).D399 35B1275 - 35B3634; install a 5N3804 Shaft (9).(4) For all engines with serial numbers given on illustrations 1, 2 and 3 install 1N9349 Seal (10) (seal lip toward inside of oil pump) in the new 5N3806 Housing Assembly (11). Install housing assembly (11). On all engines not already so equipped, install 5N3810 Gasket (12) and 8N1839 Cover Assembly (13). [Some late model engines already have the 8N1839 Cover Assembly (13).] For D379, 68B3060-68B5182 and D398, 66B4163-66B4180, one additional 7F8698 Bolt and nine 5L6267 Washers are needed to install housing assembly (11). For D379, 68B2540-68B5182, D398, 66B3561-66B6058 and D399, 35B688-35B3634, use the L2070 Bolt and S1590 Bolts with 5M2894 Washers to install cover assembly (13). (5) Put a 5N3813 Coupling on the end of the oil pump shaft. For D379-68B5183-up, D398, 66B6059-up and D399, 35B3635-up use the 5N3812 Gasket and the former bolts and washers that fastened plate (7) to cover assembly (8) (see step 1, illustration 4), to fasten control group (14) to cover assembly (13). For earlier engines, use nine 5M2894 Washers and one T573 Bolt, four L1143 Bolts and four 1A2029 Bolts, to fasten control group (14) to cover assembly (13). (6) Remove the three plugs from the rear of cover assembly (13). Remove the 3J5389 Pipe Plug from the oil pan (in front of the oil pressure regulating valve) and
