The Mercedes-Benz L 1113 is a medium-duty two-axle truck of the Mercedes-Benz brand that was built by Daimler-Benz AG at the Mercedes-Benz plant in Mannheim . Production of the vehicle, initially designated as the L 322 , began in 1959, followed by the L 1113 in 1963 . The L 1113 was produced until 1984. The L 1113 is available as a flatbed and tipper truck with and without all-wheel drive as well as a tractor and a chassis for special bodies. A forward control variant was also built as the LP 1113 .

Vehicle history

The L 1113 was created on the basis of Seebohm's laws . Daimler-Benz's objective was to build the truck as light as possible and with the largest possible loading area, without constructing a cab-over- engine truck, as it was not foreseeable at the end of the 1950s whether the cab-over-engine would prevail with customers in the long term . So it was decided to compromise on the short hood , which has the advantages of a hood handlebar , but offers far more payload and loading space. In March 1959 the truck, initially designated as the L 322 , was presented to the press. A forward control version was also available directly from the factory; previous front-link trucks from Mercedes-Benz were only delivered as chassis and provided with a body by external companies.

The L 322 was engineered from 1959 to 1961 with engines from the OM 321 series, which developed 110 hp / 81 kW. They were followed by engines from the OM 322 series from 1961, with an initial output of 126 hp / 93 kW. From 1963, the vehicles were redrawn as L 1113 . The first two numbers indicate the total mass in tons, the two following numbers one-tenth of the engine power in hp. This designation was retained even after the engine power was later increased. The second revision of the series took place in 1964, when the prechamber engines of the OM 322 series were replaced by engines of the OM 352 series. The new engines of the OM 352 series are distinguished from their predecessors by their direct injection , which is intended to reduce fuel consumption by up to 15%. The nominal output of 126 hp / 93 kW and the torque of 36 kpm / 353 Nm did not change at first; from 1966 the L 1113 was also available with the turbocharged OM 352 A, which developed 150 hp / 110 kW.

Another facelift followed in 1967 in which the cab was revised. These models can be recognized by the raised front window. In the further course, a more powerful engine was offered again with an output of 168 hp / 124 kW. The last facelift of the L 1113 followed in 1980, which was limited to small changes. Vehicle production was stopped in 1984, some vehicles were also delivered after this date , between 1982 and 1991 the federal government procured a total of 602 LF 16-TS vehicles (these were carried out by Lentner , Odenwaldwerke and Magirus-Deutz ), which today (2019) some are still in use.

L 322 (1959-1963)

Chassis and power transmission

The L 322 is a two-axle truck with a ladder frame and rigid front and rear axles . Five different wheelbases were offered, from 3200 to 5170 mm. The axles are each suspended on two semi-elliptical springs, the rear axle is also provided with two progressive auxiliary springs, while the front axle also has telescopic shock absorbers . The front axle has single tires, the rear axle is equipped with twin tires. The wheels are steel disc wheels. The tires of size from 8.25 to 20 eHD Super be divided on tapered rims raised the size of 6.5 to 20. In addition to Daimler-Benz itself, the suppliers for the brake system were Bosch and Teves. The brake system is a hydraulic brake system with a single-chamber compressed air brake aid, the braking force acts on brake drums with a diameter of 408 mm on all four wheels, with the exception of all-wheel-drive models with a front brake drum diameter of 400 mm. The handbrake is mechanical and acts on the brakes on the rear wheels. The manufacturer of the steering is Daimler-Benz, it is a recirculating ball steering system with an undivided tie rod . All vehicles were available as both left-hand and right-hand drive.

The force from the engine via a single dry type Fichtel & Sachs H 32 transmitted to the transmission. The gearbox is a fully synchronized five-speed gearbox from Daimler-Benz that is interlocked with the engine. It is shifted with a shift lever located next to the driver's seat, which acts directly on the transmission. The drive is from the transmission power over a two-piece propeller shaft to a hypoid - bevel gear axle drive transfer which transfers the force to the rear axle.

All-wheel drive models have three cardan shafts as a power transmission element. In addition, they have a transfer case with freewheel, which has a road and off-road transmission. The ratio from the gearbox to the front axle is 7: 1 lower than that to the rear axle with 6.857: 1. On the road, only the rear wheels are driven; if the wheel slip is too great, the power is also transferred to the front wheels. The differential gears can be locked.

OM 321

The first engine offered from 1959 to 1961 is the OM 321 , which was already used in the Mercedes-Benz L 321 . It is a standing series - six-cylinder - four stroke - diesel engine with two valves per cylinder, indirect injection and water cooling . The cylinder block made of chrome-alloyed cast iron and the split crankcase are made from a single cast. With a cylinder bore of 95 mm and a piston stroke of 120 mm, the engine has a total displacement of 5103 cm³. The pistons are forged pistons made of light metal from Mahle , each with four compression rings and two oil control rings . The force is transmitted via diagonally split connecting rods with a double-T cross section to a forged crankshaft with seven bearings, hardened at the bearings. The connecting rod and crankshaft have three-component bearings with steel support shells. The crankshaft is equipped with counterweights and vibration dampers.

A camshaft with four bearings in plain bearings runs in the crankcase and is driven by the crankshaft via helical spur gears. It operates the vertically suspended valves via tappets , push rods and rocker arms . Each cylinder has an inlet and an outlet valve. The cylinder head made of chrome-alloyed cast iron, which covers all cylinders, has an asbestos-containing gasket.

The pressure circulation lubrication works with a gear oil pump and an oil filter in the main flow. The fuel is cleaned through a felt tube filter and injected into the prechambers with a Bosch PES 6 A70 B 410 RS 64/7 injection pump through Bosch DNO SD 211 injection nozzles . The injection pump has a variable speed controller. The air is cleaned with a paper air filter. The engine is cooled with a tube cooler, the warm exhaust air of which is blown away by a fan.

This engine develops 110 hp / 81 kW at 3000 min −1 and delivers a torque of 30.5 kpm / 299 Nm at 1600 min −1 .

OM 322

The OM 322 was offered from 1961. This is a revised version of the OM 321, also a series - six-cylinder - four stroke - diesel engine with two valves per cylinder, indirect injection and water cooling . This engine has the same essential features as the OM 321, but with a cylinder bore of 97 mm and a piston stroke of 128 mm, it has a total displacement of 5675 cm³. The pistons each have three compression rings and two oil control rings , the first compression ring is chrome-plated. The force is transmitted to the crankshaft via diagonally split connecting rods made of heat-treated steel with a double-T cross-section. The remaining differences are valve seat rings on the exhaust valves and another Bosch PES 6 A 80 B 410 RS 174/7 injection pump with a centrifugal governor .

L 1113 (1963-1984)

The L 322 was initially only renamed the L 1113 in 1963 and this did not change technically. The visual difference between the L 322 and L 1113 is the position of the indicator, on the L 1113 the front indicators are on the fenders; however, some L 322s also have this indicator position. Changes were also made to the ratio of the steering gear, the ratio of the five-speed gearbox and thus the oil fill quantity of the gearbox housing and from 1967 on the driver's cab. From 1964, the OM 322 pre-chamber engine was replaced by the OM 352 direct injection engine.

OM 352

The OM 352 is also a series - six cylinder - four cycle - Diesel engine having two valves per cylinder and water-cooling , substantial difference from the OM 322 and 321 is the direct injection into the piston recess. The engine's cylinder block is cast from molybdenum-chromium alloyed special cast iron, the crankcase is made from alloyed special gray cast iron. With a cylinder bore of 97 mm and a piston stroke of 128 mm, the engine has a total displacement of 5675 cm³. The pistons are forged pistons made of light metal from Mahle , each with three compression rings and two oil control rings . The force is transmitted via diagonally split connecting rods made of heat-treated steel with a double-T cross-section to a forged crankshaft with seven bearings, hardened at the bearings. The connecting rod and crankshaft have three-component bearings with steel support shells. The crankshaft is equipped with counterweights and vibration dampers.

A camshaft made of hardened heat-treatable steel with four bearings in plain bearings runs in the crankcase and is driven by the crankshaft via helical spur gears. It operates the hanging valves via bumpers and rocker arms . Each cylinder has an inlet and an outlet valve. The cylinder head made of molybdenum-chromium alloy special cast iron, which covers all cylinders, is sealed off from the cylinder block with an asbestos-containing cylinder head gasket.

The pressure circulation lubrication works with a gear oil pump and an oil filter in the main flow and an oil filter in the bypass flow. The fuel is cleaned through a felt tube filter and injected into the piston bowls with a Bosch PES 6 A70 C 410 RS 2085 injection pump through Bosch DLLA 150 S 187 injection nozzles . The injection pump has a centrifugal governor. The air is cleaned with an oil bath air filter. The engine is cooled with a tube cooler, the warm exhaust air of which is blown away by a fan.

This engine develops 126 hp / 93 kW at 2800 min −1 and delivers a torque of 36 kpm / 353 Nm at 1600 min −1 . From 1966, the engine could also be provided with a turbocharger as OM 352 A, its output increased by the charging of 150 hp / 110 kW at 2800 min -1 , a further revised version OM 352 X provides 168 hp / 124 kW at 2800 rpm - 1
