What's wrong?
The Miller Enpak A60GBH on 2021-2022 Maintainer Crane W/ Service Body trucks is an auxiliary power unit. It supplies power for service-body equipment without relying only on the truck's main engine. A sheetmetal guard inside the unit is supposed to keep the Enpak drive belt and pulley away from the power cable, fuel hose, and nearby wiring.
On affected trucks, that guard was reinstalled in the wrong position after Maintainer installed body wiring. Instead of shielding the cable and hose, the misplaced guard can push them toward the moving belt and pulley. As the Enpak runs, belt contact can wear through a power cable or diesel fuel hose, damaging the cable or allowing fuel to leak.
There is no dependable warning sign before failure while the Enpak is operating. If the power cable is damaged, the Enpak can fail to start. If the fuel hose is damaged, the unit can stall or leak fuel.
