ZP 01.625 Reverse Half-Axle Assembly (Without Wheel)

ZP 01.625 Reverse Half-Axle Assembly (Without Wheel)

The ZP 01.625 reverse half-axle assembly without a wheel is a ready-to-install mechanical running gear block engineered for self-propelled ZM-60U, ZM-90U grain throwers and ZMB series hopper loaders. This configuration is a fully assembled power unit containing all drive, support, and locking components of the side assembly, excluding the running wheel itself. This supply format is a rational engineering solution for scheduled overhauls or rear axle modernization, allowing you to update worn internal running mechanics without unnecessary expenses on purchasing new wheel disks and tires.

Practical Advantages of the ZP 01.625 Assembly Without Wheel Configuration

Economic rationality while preserving wheel service life serves as the primary financial argument favoring this item. Wear-resistant 500 mm diameter ZPT 1.6.3 rubber-tired wheels-comprising a durable 6 mm thick welded steel disk and a pressed-on solid bandless rubber tire-wear down much slower than internal moving parts. Frequently, the metal rim and rubber tread remain in serviceable condition while internal mechanisms fail: the drive shaft wears down in friction zones, clutch cams round off from jerking, springs sag, and cermet bushings fracture. Notably, such wear is a natural outcome of years of intensive agricultural operation. In our upgraded units, this factor is minimized through the use of reinforced steels, high-precision hardening of working zones, and the elimination of shaft-weakening grooves, guaranteeing a substantially higher safety margin compared to standard parts. Nevertheless, purchasing a complete set alongside new wheels is frequently impractical; consequently, supplying the ZP 01.625 half-axle without a wheel disk enables agricultural enterprises to acquire factory-grade upgraded running gear simply by transferring their existing wheels onto the new hubs.

The fully ready-to-install power block eliminates the need to perform complex, precise, and time-consuming workshop machining-the assembly arrives factory-calibrated. 11206 bearings are already mounted onto the steel shaft inside H 026.058 cast-iron housings sealed by H 026.163 covers. The internal support cavities are protected against dust infiltration, while the ZP 01.102 half-clutch, heavy-duty spring, washer, and latch mechanism with ring are pre-assembled and adjusted for effortless switching between transport and working modes. To commission the unit, securing the ready axle to the grain thrower frame, bolting existing wheels to the ZM 01.180 hub flange, and connecting the drive chain is all that is required.

Technological strength and protection against critical overloads are engineered into every component of our design. The unit's foundation is the upgraded 30 mm ZP 01.625 shaft, featuring a geometry completely free of weak points such as snap-ring grooves, which substantially increases the axle's resistance to deformation. The ZM 01.180 hub is equipped with porous 30x40x25 mm cermet bushings that facilitate effortless wheel rotation on the shaft during machine transport. Replacing vulnerable pin-based drive sprocket attachments that frequently shattered under working loads, our new layout utilizes a secure keyed connection. The sprocket is rigidly fixed to the shaft via a prismatic key and additionally secured with a set screw, eliminating backlash, preventing axial component displacement under vibrations, and guaranteeing stable torque transmission even under extreme operating conditions.

Custom ZP 01.625 Shaft Reinforcement Option

Accounting for the harsh operating conditions of grain throwers across individual farms-such as prolonged equipment transit across damaged surfaces or round-the-clock warehouse loading cycles-we offer optional additional reinforcement. Upon custom order, we can manufacture the drive shaft from high-strength 40X alloy steel featuring localized thermal hardening of working zones. This increases the axle's resistance to extreme torsional loads and completely eliminates deformation or crushing of keyways caused by vibrations and transmission shock impulses.

Buying the ZP 01.625 Half-Axle Assembly (Without Wheel) from Zavod Moroza

Zavod Moroza is a full-cycle manufacturer of original and upgraded spare parts for grain cleaning and loading machinery across generations. Our products undergo factory inspections for concentricity, runout, and working tolerances, guaranteeing trouble-free component installation during running gear repairs.

To maximize maintenance convenience and align precisely with your objectives, we offer several configuration options for the ZP 01.625 half-axle supplied as cohesive, ready-to-install engineering solutions. The most practical choice for rapid scheduled repairs is the ready assembly unit-in this format, you receive a complete ZP 01.625 half-axle without a running wheel, containing the entire pre-mounted set of bearings, clutch, sprocket, springs, and associated parts. This allows you to renew internal running mechanics and restore operational service life utilizing your own surviving wheel disks, significantly preserving your farm budget. If your wheel base has undergone modifications during prior repairs or equipment operates under ultra-high loads, custom-adapted components are available. We offer reinforced drive shafts made from high-strength 40X alloy steel with localized hardening, as well as precise mechanical fitting of cast-iron hub bores to match your specific disks or previously restored shafts. To execute complete technical re-equipment and enhance classic machine maneuverability, we supply symmetric reverse axle modernization kits. These kits are designed for older ZM-60 grain thrower models and include two identical mirrored shafts assembled with cam clutches. Installing this kit allows both wheels to be fully uncoupled from the transmission during towing, entirely removing parasitic loads and protecting internal gearbox components from wear.
