Advance-Design Trucks
1948
• 216.5 cubic inch engine; low pressure inline-6 engine with 30 psi oil pressure gauge.
• 235 cubic inch engine was available on larger trucks; this was also a low-pressure inline-6 engine with 30psi oil pressure gauge.
• A closed-type vacuum-operated engine ventilation system (PCV) was available on the new 3742 Forward Control Delivery Chassis series. These trucks were used for stop-and-go delivery and a lot of standing-running, with insufficient windstream for the standard road draft tube engine ventilation to be affective (needed to minimize oil dilution and sludge formation).
• Significant internal changes were made to both the 216 and 235 engines.
• Cloth-braided wiring.
• During 1947-48, the Chevrolet painted grille-bars and "back splash" bars were body color. In addition, the leading edge of each painted outer bar had a horizontal stripe matching the cab stripe.
• On chrome grilles, only the outer bar was plated and the "back splash" bars were painted the body color, same as the painted grille.
• Windlace around door is black rubber and secured with metal strips screwed in place.
• Gas tank is still under bed.
• Bed still contains 9 boards.
• Headliner center bow is screwed in place.
• Redesigned three-speed transmission now uses column shift with linkage attached to the transmission case side; and, the parking brake is now activated by a pedal through the left side of the floorboard (allowing the driver to easily exit on the curb/passenger side - the exterior door lock is on this side). A new fender skirt was needed for the parking-brake pedal-mounting lever.
• The four-speed transmission is now synchro-mesh and slightly longer than the previous four-speed. The length of the 3-speed transmission was increased the maintain interchangeability.
• Die-cast metal hood emblem (same as 1947)
• A 15" wheel tire was now available on 3100 series
• Serial #'s, FP 1/2 ton, FR 3/4 ton, FS 1 ton, etc...
