When the worn out 3208 blew chow, I was the one laying on my back that had to reseparate the BRAND NEW motor from the tranny and cold chisel the sheared off flywheel bolts that the day laborer/"pro mechanic" did not torque the bolts when he bolted the clutch to the flywheel. I was pretty steamed.
Yeah, that thing was a beast... nobody else on the gang would drive it. It had airbrakes, and even though it's gross vehicle weight was under the limit, they all thought you needed a CDL to drive it... so I drove it everywhere. I was always vigilant to not hook my thumbs on the steering wheel just for the reason you wrote of.
