Frame: Description and Operation
FRAME AND BODY MOUNTINGThe frame is made up of two steel channel rails and riveted crossmembers, except for the transmission support crossmember and engine support crossmember which are bolted. The E-550 is a bolted together split frame. Vehicle application determines the crossmembers used.
The vehicle body sits on rubber body supports. There are lower and upper body supports to keep the vehicle body from sitting directly on the frame.
