Where are the lubrication ramps that direct oil to the drive links located?

• A. On the guide bar rail
• B. On the chain
• C. Inside the engine cover
• D. On the guide bar rail, near the drive links

Answer: (D)

The lubrication ramps are features built into the guide bar rail that sit near where the drive links ride. Their job is to redirect oil from the bar’s oil path onto the moving drive links so they stay lubricated as they pass by the bar groove. They’re not on the chain or inside the engine cover, and placing them on the chain wouldn’t effectively deliver oil to where the drive links need it most. So, the correct placement is on the guide bar rail, close to the drive links.
