^{ZF TRANSMISSION, DIFFERENTIAL AND AXLE PARTS FOR TRUCKS AND HEAVY EQUIPMENT}

ZF transmission, differential and axle parts are widely used in both heavy duty trucks and construction machinery. These systems are designed to operate reliably in haulage, construction and industrial environments where high torque, continuous load, durability and lower total cost of ownership are critical requirements.

^{Ordering by unit number}

Every part is defined by the unit type and its original number. A ZF gearbox or axle carries its own plate with a model designation and serial number, for example 16S1820, 16S1650, 9S1310, 6S1000, 4WG200 or APL 345. Sending that designation together with the part number is enough for accurate selection. The same truck or machine model was built with different unit variants over its production years, so the vehicle model alone is usually not enough.

^{ZF transmission systems for trucks and construction vehicles}

ZF transmission systems are used in haulage trucks, construction dump trucks and heavy duty vehicles operating on road and off road. Key components include transmission gears, input shafts, main shafts, countershafts, synchronizers, selectors, reverse gears, repair kits, bearings, seals, O-rings and sealing elements. Parts are supplied for the Ecosplit and Ecomid manual ranges, including 16S, 12S, 9S and 6S units, and for the automated AS Tronic and TraXon gearboxes. Precision gear manufacturing ensures smooth shifting, efficient power transfer and long service life in demanding applications.

^{ZF off highway transmissions for construction machinery}

ZF off highway transmissions are fitted to wheel loaders, backhoe loaders, motor graders and other construction machines. Parts are supplied for the Ergopower 4WG, 6WG and 3AVG ranges, including 4WG160, 4WG180 and 4WG200: friction discs and steel plates, clutch packs, gears, shafts, planetary sets, transmission pumps, solenoids, bearings, seals and complete repair kits.

^{Differential and axle components}

ZF differential and axle systems are engineered to distribute torque efficiently under varying load conditions. This group includes differential gears, crown wheel and pinion sets, bevel gears, differential cases, spiders, side gears, planet gear sets, sun gears, axle shafts, splined axle shafts, rear axle differentials, wheel hub kits, wheel bearings, thrust washers, flanges, housings, covers and complete assemblies. Parts are supplied for the APL and AV axle ranges used on loaders and off highway machines, as well as for truck drive axles. These components are essential for stability and traction.

^{Propeller shaft and driveline components}

Propeller shafts and driveline components connect the transmission to the axle system. This category includes propeller shaft carriers, universal joints, double U joints, drive shafts, output flanges and related mounting components. Proper driveline alignment reduces vibration and improves operational reliability in trucks and heavy construction equipment.

^{Torque converters and planetary systems}

Torque converter systems are used in construction machinery and power shift transmissions. Components such as torque converter impellers, turbines, stators, connection plates, transmission pumps, planetary gear systems, planetary carrier kits, planetary shafts and wheel end planetary assemblies support torque multiplication and controlled power delivery under heavy load conditions.

^{Steering, wheel end and brake components}

ZF powertrain solutions also include steering and wheel end components such as swivel housings, king pins, wheel carriers, spindles, brake discs, clutch discs, dampers, bushings, pins and torsional vibration dampers. These components contribute to vehicle control, braking performance and overall operational safety.

^{Bearings, seals and repair kits}

Transmission, axle and planetary reduction bearings, shaft seals, hub seals, axle shaft seals, O-rings, housing gaskets, thrust washers and bushings are supplied individually and as complete kits. Gearbox repair kits, range change and shift mechanism kits and axle overhaul kits are assembled from the unit designation on the plate.

^{Application areas}

ZF transmission, differential and axle components are used in haulage and construction dump trucks, long distance transport trucks, and construction machinery including excavators, cold planers, wheel loaders, dozers, motor graders, track loaders, skid steer loaders, backhoe loaders, articulated and off road dump trucks, hydraulic mining excavators, underground and hard rock mining machines, forestry equipment and drilling rigs working in heavy duty environments.
