What's wrong?
The crane mount bolts on the 2019-2020 Maintainer Service/Mechanics Body fasten the Palfinger PSC4389 crane base to the crane mount plate on the service body. Those bolts are supposed to reach deep enough into the threaded crane base so the crane stays clamped to the mount while it lifts and moves loads.
On the affected bodies, the supplied mounting bolts are too short for the 1.5" thick crane mount plate. Maintainer found only .75" of thread engagement, while the design review called for at least 1.25". With too little thread holding the crane base, the bolts do not have the intended grip. The repair uses longer 3.25" bolts in place of the 2.5" bolts to add thread engagement.
An owner or operator would hear the bolts disengaging from the threaded crane base. If all four mounting bolts disengage at the same time, there is little to no warning before the crane is no longer secured.

What's the safety risk?
A crane that detaches from the vehicle creates a serious injury or death risk for people nearby. Listen for an audible sound from the mounting bolts, and stop using the crane if you hear it. Schedule the bolt replacement soon so the crane is secured correctly. Repair is free at any franchised Maintainer dealer.
