RING-OIL 4549573 - Caterpillar

Note: All pressures listed in Table 1 are absolute.Note: For derates, the system reaction is immediate. In these cases, the delay refers to the customer notification only.Note: In a derated condition, the amount of derate can be determined by monitoring the "Actual Maximum Available Engine Torque %". Contact your Cat dealer for more information about the derating procedure.
