Abstract: A work machine with a remote diagnostic system includes a combustion engine, a pump, a coolant temperature sensor to monitor and transmit a coolant fluid temperature, a pressure sensor coupled to an inlet of the pump, and a controller. The pressure sensor is configured to monitor and transmit a coolant fluid pressure. The controller is operatively associated with the engine, the coolant fluid temperature sensor, the pressure sensor and an equipment care advisor module. The equipment care advisor module is configured to monitor the coolant fluid temperature during a start-up of the work machine, monitor the coolant fluid pressure during the start-up of the work machine, calculate an expected coolant fluid pressure based on the monitored coolant fluid temperature and the monitored coolant fluid pressure, and generate a failure code indicating a combustion gas leak when the monitored coolant fluid pressure exceeds the expected coolant fluid pressure.

Abstract: An ingress/egress arrangement for a machine comprises an operator cabin and a walkway system outside the operator cabin. The operator cabin can include a plurality of posts, including first post and a second post, and a door rotatably coupled to the first post so as to be movable between at a fully open position and at a fully closed position. An opening in the operator cabin between the first post and the second post defines a first operator ingress/egress point. The walkway system provides operator access to inside the operator cabin via the door and the opening, and provides operator access to outside the operator cabin. The door, in the fully open position, can restrict operator access toward a front of the machine and can allow operator access simultaneously to the walkway system and a second operator ingress/egress point.
