Final answer:
When inspecting a gear type oil pump, gears and housing are inspected for scoring and damage, but there is debate over whether gear thickness and backlash also need to be measured. Professional practice usually requires these measurements for optimal pump performance and longevity.
Step-by-step explanation:
When cleaning and inspecting a gear type oil pump, there are different viewpoints on whether certain measurements need to be taken. Person A suggests that inspecting the gears and housing for scoring and damage is sufficient, implying that gear thickness and backlash are not typically measured. On the contrary, person B believes that it is essential to always measure gear thickness and backlash as part of the inspection process.
In professional settings, both of these aspects can be crucial for ensuring the longevity and proper function of the oil pump. Gear thickness determines the amount of wear which can affect the pump's efficiency and performance. Backlash, the amount of clearance between meshed gears, impacts the pump's operating noise and the smoothness of gear engagement. Although visual inspections for scoring and damage are important, ignoring measurements such as gear thickness and backlash could lead to overlooking issues that can cause pump failure or suboptimal performance over time.
