Question: During a routine weekly inspection, a heavy equipment technician observes that the grease zerks on the articulation points of a wheel loader appear dry and discoloured, indicating a lack of recent lubrication. The manufacturer's recommendation is to grease these points daily. What is the most likely consequence of neglecting this lubrication task?
Answer options: ✅ Premature wear of pins and bushings.
- Increased engine oil consumption.
- Overheating of the hydraulic system.
- Reduced fuel efficiency of the machine.
Correct answer: Premature wear of pins and bushings.
Explanation: Lack of lubrication on articulation points directly causes increased friction and metal-on-metal contact, leading to accelerated wear of critical components like pins and bushings. Engine oil consumption, hydraulic overheating, and fuel efficiency are not directly related to articulation point greasing.
