to the left, while the turbocharger is mounted behind the engine so as to provide more space and less heat soak. Export models are coded MCE and MRE respectively. The low profile cab is of steel, while the doors are fibreglass. The engine intrudes considerably into the low cab. The cab tilts through a full 90 degrees, allowing for the radiator to be removed without first removing the cab. The dashboard is lit from a single source through fibreoptics, this being a very early example of such an application.

148:, also known as the "Cruise-Hauler", is a cabover truck first introduced in 1978. It is of a distinct "set back front axle" design (first seen on the Mack FM), with the driver compartment mounted ahead of the front axle and with a large, flat, divided windscreen covering almost half of the truck's frontal aspect.
164:
The MC/MR was designed from the beginning to be available in right-hand drive as well as left-hand drive. This allowed Mack to market the truck in the United
Kingdom without costly conversions, and also opened the trash truck market at home. The right-hand drive models also have the exhaust relocated

have a multi-stage folding boom pivoted near the center of the truck and a hopper at the rear to load the pump. The pump itself is the load and the truck always operates at maximum weight. In transit the boom is folded front to rear. In use the pump uses outriggers and the boom unfolds forward over

tandem is the base rear suspension. The
Camelback has multiple leaves that rock above the bogey pivot then curve down and under the axles. It is strong in on/off-road service. It is available in ratings of 38,000, 44,000, 52,000, and 65,000 pounds (17,000, 20,000, 24,000, and

drive directly up to a container. A boom goes from the body over and then down in front of, the cab. As the truck moves forward slowly two forks pick up the container. The container is then lifted up and over the cab to be dumped into a hopper on the top of the body. Front loaders are used for

transmissions are designed to work with
Maxidyne engines and have fewer and wider-spaced gears than more conventional models. They originally had 5 speeds and developed into 8 speeds with low range gears. Other Mack manual transmissions have 5-10 speeds.
176:
Maxidyne high-torque engines have a wide power band and can develop maximum power below the governed speed they are rated at. This allows less shifting and smoother power "on the ground" when accelerating. Most MR series had
Maxidyne engines.

were rated at 10,500 or 12,000 pounds (4,800 or 5,400 kg) in light MC models but most models had between 12,000 to 20,000 pounds (5,400 to 9,100 kg). Steering could have up to a 45 cut, allowing very tight turning radius.
290:
have low bogie pivots with a balance beam going out and under the axles. Any suspension is above the bogey pivot. They can have leaf springs or be solidly mounted. Walking beams are very stable at low speeds and when stopped.
320:
have a large hopper on the rear end. Typically a rear crew can load loose material, bins with assist, oversize pieces, and small containers. They are used for residential and light commercial pickup in congested cities.

The MC was used for custom-built fire equipment, when Mack exited the market in 1990 they discontinued the MC. The MR was widely used in refuse applications and continued in production until up-graded as the MRU

222:
All manual transmission except the 6-speed had a 5-speed transmission, additional speeds were made with combinations of ranges. The lowest transmission gear can be either an on-road or very low off-road ratio.

was a 636 cubic inches (10.4 L) V8 engine. It developed 175 to 210 horsepower (130 to 157 kW) and 400 to 485 pound force-feet (542 to 658 N⋅m) of torque.

The MC was available with Mack E6 series and mid-range
Caterpillar 3208 series diesel engines. The MR was available with the E6 series and E7 series diesel engines.
