Assembled Grain Thrower Reverse Disengagement

Assembled Grain Thrower Reverse Disengagement Assembly

The complete drive disengagement mechanism kit is a professionally selected, factory-calibrated repair kit designed for installation on the leading reverse half-axle of upgraded ZM-60 and ZM-60A series machines, as well as modern ZM-60U, ZM-90U, ZM-120U modifications and ZMB and ZZP type wheeled grain loaders. This pre-assembled block combines all essential moving, power, and locking elements of the cam clutch assembly.

Supplying the unit as a kit without the steel shaft, bearing assemblies, and wheel is the most rational and cost-effective solution for many agricultural enterprises. If the ZP 01.625 drive shaft and wheel disks retain their geometry and strength, but the cam mechanism itself has worn down from prolonged operation or requires modernization, purchasing this ready-made assembly allows you to fully restore proper running kinematics with minimal financial expense. Purchasing the kit from Zavod Moroza guarantees that all mating parts will fit together perfectly, and installation will proceed without complex fitting or workshop machining at the threshing floor.

• Total weight of the kit (excluding shaft and wheel) - 6 kg.

Composition of the assembled unit:

• ZM 01.180 cam wheel hub (1 pc.) featuring two pressed-in 30x40x25 mm cermet bushings and an installed grease zerk fitting.
• ZP 01.102 cam half-clutch (1 pc.).
• ZP 01.626 heavy-duty spring (1 pc.).

• 30 ZM 01.623 retaining ring assembly with set screw and M8 nut.

Engineering Features and Kinematics of the Assembly Produced by Zavod Moroza

Reliable torque transmission and simple running control are ensured by the coordinated operation of all kit elements. In operational mode, the ZP 01.626 heavy-duty spring generates precisely calculated axial force, holding the ZP 01.102 half-clutch cams in tight engagement with the ZM 01.180 hub slots, guaranteeing rigid, backlash-free torque transmission from the gearbox to the wheel as the loaded grain thrower moves. When shifting the machine into a transport or towed state, the operator pulls the half-clutch backward using the convenient cast lever-handles, overcoming the resistance of the heavy-duty spring, at which point the spring-loaded working pin of the ZP 01.631 latch snaps into the shaft spherical pocket, rigidly locking the half-clutch in the disengaged state. The driving wheel transitions into free sliding mode on the cermet bushings, allowing the grain thrower to be safely towed while entirely eliminating gear wear within the self-propelled gearbox.

The upgraded latch featuring a convenient metal ring significantly simplifies running gear unlocking under field conditions. Instead of the classic button, which frequently slipped from fingers when operating in dusty or greasy environments, this new safety mechanism features a more massive steel ring-making it easy to grasp and pull upward even while wearing thick work gloves. The steel pin of the ZP 01.631 latch slides freely inside the guide bushing and is securely retained by the small internal spring, ensuring crisp and trouble-free mechanism actuation.

A well-designed dust protection system and clearance stability are achieved through auxiliary assembly elements. Two thickened special ZM 01.435 washers form a reliable bearing surface for the heavy-duty spring, preventing distortion or axial shifting. In turn, the 30 ZM 01.623 spacer ring allows axial technological clearances on the ZP 01.625 shaft to be set with high precision, completely blocking parasitic backlash and reliably protecting the internal hub cavities and working bushing surfaces from fine abrasive dust and debris from the threshing floor.

The reinforced flange of the ZM 01.180 hub with a centering shoulder guarantees geometrically precise wheel disk seating. Thanks to the centering projection on the flange, the wheel seats perfectly flush, preventing "figure-eight" wobble during heavy machine maneuvers. Mounting holes on the square flange are fully universal, permitting seamless mounting of both standard 400 mm rubber-tired wheels and large 500 mm wheels, such as those from OVS-25 grain cleaners.

Buying the Reverse Drive Disengagement Assembly from Zavod Moroza

Zavod Moroza serially manufactures a full range of running system components with strict quality control over materials and machining precision. All cast-iron components are cast from high-strength Grade Sch 20 gray cast iron, while seating bores and keyways undergo calibration on precision CNC machine tools.

Purchasing the drive disengagement assembly as a complete unit provides you with a fully installation-ready set of parts. Our specialists press the 30x40x25 mm cermet bushings into the hub using specialized hydraulic equipment-eliminating microcrack risks-install the grease zerk, and calibrate precise spring forces and latch travel. You simply need to slip the elements onto your steel ZP 01.625 shaft, secure them with keys and a ring, and bolt your existing wheel disk to the hub flange.

Contact our engineering and technical consultants to place your order! Because machinery across different production years may feature variations in shaft keyway length or wheel bolt patterns, we will gladly help verify all linear dimensions of your equipment prior to ordering free of charge. If necessary, we can promptly adapt the hub mounting holes or machine elements at our turning production facility to meet your specific requirements. This guarantees flawless component compatibility and rapid restoration of your machinery's operation without forced downtime during intense seasonal workloads!
