Delco-Remy Truck Equipment in World War Two:
Forty-four models of generators, 21
models of regulators, 36 models of starting motors, 31 models of ignition
distributors, 10 models of ignition coils, 3 models of storage
batteries, and 65 starting, lighting, and ignition switches for Chevrolet
and GMC trucks. This amounted to 831,546 vehicles.
The Airborne Extra-Light 1/4-Ton Jeep
Program: This 1942-43 program was initiated during World War
Two to develop a lighter version of the standard 1/4-ton jeep which could
be parachuted into a combat zone. Six companies developed samples
for U.S. Army testing. The Chevrolet entry had a Delco-Remy
experimental electrical component installed on an Indian motorcycle
engine. The component appears to be an alternator.

The Delco-Remy engineering sample sets in
the center of the engine bay. Author's photo added 5-11-2020.
A closer look shows this to be a rotating
device with a pulley and fan similar to the Delco-Remy alternators
introduced 19 years later in 1962. The three output wires go to the
voltage regulator on the fire wall, as shown in the photo above. It
appears that Delco-Remy did initial work on experimental alternators during
World War Two. Author's photo added 5-11-2020.
An alternator was a
lighter weight option than a DC generator for the extra-light jeep
program. However, the unit produces an alternating current which
needs to be rectified into direct current for use in the vehicle.
Bell Labs did not invent the transistor nor semiconductor diode until 1948. It took the intervening years to develop the technology
and manufacturing capability to furnish the six diodes each alternator
would need.
If this is actually an
alternator to reduce weight in the extra-light jeep, the rectifying
circuit would have been vacuum tubes. There are three wires
running from the output the alternator to what looks like the voltage
regulator. This would imply that the three-phase current is being
directly output to the regulator. There does not appear to be any
electrical box for six vacuum tube rectifiers. Vacuum tubes to rectify the AC
would have taken up a lot of space, added weight, and generated heat.
There is still a mystery to this unit.

Chevrolet: Chevrolet built 281,570 1/2 ton, 3/4 ton and
1-1/2 ton trucks in both 4x2 and 4x4 configurations. Among these
were trucks that bored holes for telephone poles. Others were
ambulances, pickups, fire and crash trucks, cargo, and dump trucks, to
name a few of their many uses. Different trucks with
different applications would have had different electrical requirements.
As early as 1940, Delco-Remy was providing
electrical components to Chevrolet military trucks. This is
Chevrolet 1-1/2-ton dump truck. Author's photo added 5-11-2020.
This is a 1941 Chevrolet 1-1/2-ton military
cargo truck with Delco-Remy components. Author's photo added

This 4x4 Chevrolet hole borer was one of the
more popular applications of the Chevy truck during World War Two. Author's photo.
One application for the Chevy 1-1/2 ton 4x4
truck was this bomb truck. Author's photo.
Several of
the D-R switches are on the instrument panel. The starter and headlight dimmer switches were
mounted on the floor. Delco-Remy also supplied
the battery, generator, regulator, starter, ignition coil, and distributor. Author's photo.
Chevrolet also built military crash trucks like this one.

Klaxon. Author's photo added 5-11-2020.
The Chevy trucks had Delco-Remy
voltage regulators mounted on the fire wall in
front of the driver. Author's photo.
GMC: GMC and Chevrolet manufactured 528,829 GMC 6X4
and 6X6 2-1/2 ton military trucks in various configurations. All
of these would
have had Delco-Remy electrical components.
One of the more rare models of GMC World
War Two 2-1/2 ton 6x6 trucks with D-R electrical components is this AFKWX cab over engine with an extended
cargo bed. This design allowed for a longer cargo bed for high
volume loads. Author's photo.
GMC 2-1/2-ton 6x6 fuel and oil trucks
were used at air-fields around the world during World War Two. Author's photo.
Another Delco-Remy 6 volt regulator is inside the engine bay of the GMC.
This is model number 5628 and serial number 56554. Author's photo.
This type cargo version of the GMC was the
most prevalent. Author's photo.
GMC and Chevrolet built 21,147 GMC-designed DUKW
amphibious trucks, like the one seen
here. Due to the fact that the DUKW worked in a marine
environment, Delco-Remy supplied electrical equipment that was resistant
to salt-water corrosion. Author's photo.
International Harvester, Marmon-Herrington,
and Kenworth:
This is an International H-542-9, 5-ton 4x2
tractor owned by the Navistar Corporation and stored at its Melrose
Park, IL plant. The military designation for the H-542-9 was the M425.
International built 4,640 in 1944 and 1945. International also built
6,678 H-542-15 with military designation M426. They were nearly
identical, except for larger tires and a heavier duty suspension on M426
which allowed it to pull larger loads. Author's photo added
12-1-2020.
Marmon-Herrington in Indianapolis, IN and
Kenworth in Seattle, WA also produced the M426.

Delco-Remy supplied the electrical equipment
for the 15,618 5-ton 4x2 tractors. The original 40-amp generator
was 1105864 which was later replaced by 1105871. Part
numbers for the remaining components is unknown.
The Truck, 20-Ton, 6x4, Diesel was a Federal
Truck Company of Detroit, MI design, which was also built by The Reo
Motor Car Company in nearby Lansing, MI. The trucks were designed
and built to pull semi-trailers with heavy loads, including tanks.
The one shown above is a Federal-built unit because it has a winch.
Reo only built the non-winch version. Both types were powered by a
Cummins HB600 engine. Delco-Remy shipped the cranking motors and
DC generators to Cummins Engine Company in Columbus, IN. D-R also
shipped switches to Federal Truck in Detroit and the Reo Motor Car
Company in Lansing, MI.

General Motors of Canada:
General Motors of Canada built 201,000
Canadian Military Pattern (CMP) trucks during World War Two. The
Canadian military required both General Motors and Ford to build the
same basic vehicle for standardization. The CMP trucks were based on a
British 15-cwt vehicle. The GM of Canada versions were Chevrolets,
as denoted by the bowtie on the grill. The GM of Canada CMPs
vehicles were
powered by Chevrolet 85 hp engines. Author's photo added

Sterling Motor Truck Company:
Sterling was a small heavy-duty truck manufacturer located in Milwaukee,
WI.
The Sterling Motor Truck Company of
Milwaukee, WI built 50 DD115 4x4 tractors for the U.S. Navy in World War
Two. The DD115 was powered by a Waukesha 6SRKR six cylinder engine
with a Delco-Remy electrical system. The part numbers were:
cranking motor - 412, DC generator - 934D, voltage regulator - 1118210,
distributor - 640C, ignition coil - 1115079. Image courtesy of
Warren Richardson added 12-24-2020.
Federal Type Model 605 F-1 Aviation Fuel Tractors:
Two hundred of these were built for the USAAF.

12-24-2020.
While the engine ignition system was
Delco-Remy, the 12 volt battery was manufactured by Exide. Other
heavy duty trucks had Willard batteries. Delco-Remy batteries did
not have much or any penetration into the heavy duty truck market during
World War Two. It may have been running at capacity to supply all
of the Chevrolet and GMC trucks during the war. The Muncie battery
plant was also producing aircraft batteries and supercharger blowers for
the war effort. Image courtesy of Jeff Lakaszcyck added 12-24-2020.
The Delco-Remy part numbers were: cranking
motor - 494, DC generator - 934T, voltage regulator - 1118210,
distributor - 4169, ignition coil - 1115251. The Federal F1 fuel
truck used two ignition coils.
The magnetic starting switch was model
number 1422. Image courtesy of Jeff Lakaszcyck added 12-24-2020..
Federal Type C-2 7-1/2-ton 6x6 606 Aircraft Wrecker: The C-2
was powered by a Hercules Model HXD six cylinder 855 cu. in. engine,
which enabled the truck to pull 12.5 tons when hooked up to a trailer.
The truck could perform several different tasks. However, its primary
job was to pick up disabled aircraft and place them on a trailer to take
to the repair facilities. It was also used extensively for
aircraft engine changes. Every AAF Air Base had at least one C-2.
While one C-2 could lift most aircraft on its own, it took two to lift a
B-17, so the bases with heavy bombers or transports like the C-54 would
have had two.
Federal built 2,500 Federal 606 aircraft
wreckers for the USAAF. The USAAF designated it as the C-2.

This is another protype 8-ton 8x8 cargo
truck designated T20E and built by the Corbitt Company of Henderson, NC.
This is one of three that were built at the end of World War Two.
It had
12 volt Delco-Remy electrical systems. The generators were a 55
amp units. The T20E never went into production. Author's
photo added 12-1-2020.
Low-Speed Tractors: These are
construction-type crawler tractors that were not intended for the
cross-country pulling of heavy artillery pieces, although they were used
for that function during the war along with traditional construction
work.
This is a 1942 Allis-Chalmers TD-18 tractor
built for the U.S. Army Corps of Engineers. It was photographed by
the author at the 2020 Antique Gas Engine and Tractor Show in Portland,
IN. Note that there are ignition wires on the engine and two
exhaust stacks. Photo added 9-2-2020.
The U.S. Army nomenclature identified this
as a Tractor, Heavy M-1. Allis-Chalmers built 315 TD-18s
in 1942 and a total of 747 units during World War Two for the U.S. Army.
Delco-Remy supplied the electrical components for these 747 TD-18s.
Author's photo added 9-2-2020.

This side of the engine shows it to be
a six cylinder diesel engine. Note there is a gasoline container
on the track and a bird's nest on top of the engine. Author's
photo added 9-2-2020.
I had never seen anything like this
before. Further research found that the six cylinder gas engine
was used to start the engine before the diesel was turned on.
Author's photo added 9-2-2020.
Further examination found that the
distributor, DC generator, and voltage regulator were built by
Delco-Remy. Part of the distributor is hidden behind the
carburetor. While the starter could not be seen, it is assumed to
be a Delco-Remy unit also. Author's photo added 9-2-2020.
Author's photo added 12-1-2020.
This is part number xxx0152 which is most
likely 1110152. It was a clockwise rotation distributor. The

High-Speed Tractors: These
tractors were specifically designed to pull heavy artillery
and were faster than the low-speed tractors.
The Allis-Chalmers M4 high speed tractor was powered by a Waukesha 145GZ
engine which had a Delco-Remy 644 heavy duty rear reduction cranking
motor. Author's photo added 5-10-2020.
Author's photo added 5-10-2020.
This is one of two surviving Allis-Chalmers
M6 high speed tractors of the 1,235 built during World War Two.
Like the smaller M4, it was powered by two Waukesha 145GZ engines
with a Delco-Remy electrical system. This is on display at the Overloons Military Museum in the Netherlands. Photo added
