ZM 01.180 Hub + ZP 01.102 Half-Clutch Set

ZM 01.180 Hub + ZP 01.102 Half-Clutch Set (Reverse Cam Pair)

The set comprising the ZM 01.180 cam hub and the movable ZP 01.102 half-clutch forms the core functional assembly within the ZP 01.220 rear wheel drive control mechanism. This working tandem is engineered for installation on self-propelled ZM-60U and ZM-90U grain thrower series, as well as analog wheeled grain loaders, and is also utilized when modernizing and converting classic ZM-60 machinery to a symmetric rear axle drive layout.

The set is directly responsible for promptly engaging and disengaging the driving wheels from the machine's tractive transmission. In operational mode, under the pressure of the heavy-duty spring, the four rectangular half-clutch cams rigidly lock into the hub slots, ensuring the transmission of torque from the self-propelled gearbox drive chain directly to the wheel disk. When shifting the machine into a transport or towed state, the half-clutch is pulled back manually, breaking the engagement-in this position, the hub rotates freely on the stationary shaft, entirely removing the load from the internal gears and planetary gears of the self-propelled gearbox.

Technical Specifications of the Cam Set

• Assembly composition - support-and-drive ZM 01.180 hub and movable ZP 01.102 half-clutch.
• Application - ZM-60U, ZM-90U grain throwers, ZMB and ZZP series loaders, and for retrofitting the reverse gear of classic ZM-60 models.
• Component material - Grade Sch 20 gray cast iron featuring high wear-resistant characteristics.
• Total set weight - 5.1 kg (hub - 3.31 kg, half-clutch - 1.79 kg).
• Set mounting fit - onto a 30 mm diameter shaft featuring two keyways for 8x7 mm prismatic keys. The ZM 01.180 hub comes pre-equipped with two pressed-in 30x40x25 mm cermet bushings.
• Wheel disk mounting interface - reinforced square flange with 4 mounting holes for M12 bolts and an integrated centering collar.
• Sliding assembly maintenance - direct M10x1 grease zerk fitting mounted directly into the hub neck.

Advantages of Replacing the Grain Thrower Hub and Half-Clutch as a Set

Factory reciprocal matching of working profiles serves as the primary argument favoring the acquisition of these components as a set. During running gear operation, the half-clutch cams and hub slots experience significant alternating loads and transmission shock impulses when the machine starts moving from a standstill. Installing new components as a paired set guarantees ideal spatial concentricity, the complete absence of initial backlash, and an even distribution of forces across the entire cam contact area, eliminating the risk of local protrusion deformation, preventing their "rounding off," and substantially extending the assembly's overall inter-repair service life.

The integrated centering collar on the hub square flange ensures geometrically precise and stable fixation of the running wheel. A specialized circular projection at the center of the flange fits snugly into the central bore of the wheel disk, allowing the four M12 mounting bolts to be unloaded from radial loads and shear forces generated by the weight of the heavy trimmer and grain thrower frame. The wheel disk seats without the slightest skewing, preventing radial runout and the elongation of mounting holes during operation.

Rapid and efficient maintenance without component disassembly is achieved through a modified sliding bearing lubrication scheme. A threaded grease zerk fitting is screwed directly into the neck of the ZM 01.180 hub at the factory, with the lubrication channel routed precisely into the internal cavity between the two pressed-in 25 mm long cermet bushings. To supply fresh consistency grease (solidol or litol), the operator simply utilizes a standard grease gun-the lubricant fills the internal chamber and evenly impregnates the porous cermet structure directly on-site, eliminating the need to disassemble the half-axle or remove heavy wheel disks from the flanges.

The thoughtful ergonomics and functionality of the ZP 01.102 half-clutch simplify and facilitate manual drive control. The component is equipped with two massive cast lever-handles that allow the operator to firmly grasp the clutch and easily overcome the resistance of the clamping spring. A precise threaded port is machined into the cylindrical body of the half-clutch to mount the spring latch bushing, which cleanly secures the component in idle mode. Simultaneously, the internal bore of the component contains two precise keyways, ensuring smooth sliding of the clutch along the shaft during drive disengagement.

Buying the "Hub + Grain Thrower Half-Clutch" Set from Zavod Moroza

Zavod Moroza executes a full technological cycle of component manufacturing-from precise Sch 20 grade cast iron foundry work in our own workshops to finish machining of seating zones, keyways, and threads on advanced CNC machine tools. Our products strictly comply with all drawing geometric parameters and undergo rigorous technical inspections prior to customer dispatch.

We offer several convenient configuration options for the cam pair tailored to your farm's individual requirements. The primary and most practical solution is the standard operational assembly set-in this format, you receive the ZM 01.180 hub with a pre-installed grease zerk and 30x40x25 mm cermet bushings professionally press-fitted on our factory hydraulic press, alongside the fully compatible ZP 01.102 half-clutch. Because our updated design supplies the hub equipped with bushings by default, factory press-fitting entirely protects the fragile powder cermet from accidental cracking or edge chipping commonly encountered when attempting to drive components in with a hammer in a farm workshop. Upon custom customer request, we can supply bare cast-iron castings without internal sliding elements, though ready factory modules guarantee maximum installation speed and prolonged operational service life.

To execute a major overhaul or reconstruction of the reverse gear system, we supply a complete set of drive disengagement components. Within this configuration, the cast-iron cam pair ships alongside a full complement of associated control mechanism elements. This includes the calibrated ZP 01.626 heavy-duty spring maintaining stable cam engagement force, durable ZM 01.435 support washers, a set of prismatic keys for precise clutch seating on the shaft, and the ZP 01.631 spring latch assembly equipped with a metal ring. All of this enables a complete overhaul of the running side without needing to source minor fastening or locking spare parts.
