Which component directly directs lubrication to drive links in the Ematic Bar Lubrication System?

• A. The drive links themselves
• B. The fuel injector
• C. The spark plug
• D. Two ramps on the guide bar rail

Answer: (D)

Lubrication in the Ematic Bar system is guided by features built into the bar itself. Oil travels through the bar’s lubrication channel, and as the chain moves, two ramps on the guide bar rail press against the oil, acting to push it along the channel toward the drive links. This arrangement ensures the oil is delivered exactly where the chain and bar surfaces contact each other, keeping those moving parts properly lubricated. The drive links don’t direct the oil themselves—they receive it. The fuel injector and spark plug belong to the engine’s fuel and ignition systems, not to bar lubrication, so they don’t direct lubrication to the drive links.
