🔍 Key Concepts

• Identify what type of system this is by tracing how the motion from the central mechanism is transmitted to components D, E, F, and G. • Think about the purpose of tall, sealed cylinders mounted above a hydraulic or mechanical linkage system on a large diesel engine. • Recall how large slow‑speed marine diesels change direction of rotation and what kind of force is needed to move the camshaft assembly.

💭 Think About

• From the illustration, what do B and C appear to be connected to, and do they seem to deliver lubrication, control oil, grease, or stored energy? • If the device attached to H, I, J, K, L, and M has to move something heavy quickly and accurately, which of the answer choices best matches that kind of task? • Does component F look like a bearing or wear point needing constant lubrication, or does it look more like part of a motion‑transmitting linkage?

✅ Before You Answer

• Verify whether any oil passages or grease lines run from B and C directly to F (they should be clearly shown if that were their function). • Check if B and C resemble accumulators or pressure tanks feeding a hydraulic piston (H/I/J/K/L/M) that then moves the linkage to D/E/F/G. • Confirm which of the choices describes a function that would require a pair of pressurized cylinders rather than a small pump or simple lubricator.
