When an additional load is applied to a diesel engine which is using an inadequately inflated air bladder clutch unit, you can expect_______________.

Aexcessive wear on the thrust bearings
Bpneumatic seizure
Cchipped reduction gear teeth
Doverheating because of slipping shoes
AI Explanation

The correct answer is D) overheating because of slipping shoes. When an additional load is applied to a diesel engine using an inadequately inflated air bladder clutch unit, the clutch shoes will begin to slip against the drum. This slipping action creates friction and heat, leading to overheating of the clutch assembly. The other options are incorrect because they do not directly result from the slipping clutch scenario described in the question. Excessive wear on thrust bearings, pneumatic seizure, and chipped reduction gear teeth could occur due to other issues with the diesel engine or transmission system, but they are not the primary consequence of a slipping air bladder clutch under increased load.
