--------------- END SUPPLEMENT ---------------
Due to intake port and inlet valve deposits, 3600 Customer Services recommends shutting off the oil mister pump or pumps on all 3600 Engines using heavy fuel oils (HFO). Use the following procedure to disable the 7C-1190 Pump or Pumps. Note: 3606, 3608, and 3612 Engines have one 7C-1190 Pump. 3616 Engines have two 7C-1190 Pumps.

1. With the engine shut down, disconnect the lubrication lines (B) from the 7C-1190 Pump (A). As each lubrication line is disconnected, use 9L-8493 Caps and 9S-5518 Plugs to block of the lines and pump connections.
2. Remove the two bolts (C) that fasten the pump (A) to the adapter (D). Remove the pump from the adapter.
3. Remove the 7C-1642 Coupling (F).
4. Be sure the O-ring seal (E) is in position adapter (D). Reinstall the pump (A) on the adapter (D) with two bolts (C). The lubrication lines (B) and pump ports should remain capped and plugged.
NOTE: If the mister lines are leaking, remove the lines. Leaking mister lines can result in a boost loss.
