ZP 01.627 Reverse Half-Axle Assembly with Wheel (Blind, Right)

ZP 01.627 Reverse Half-Axle Assembly with Wheel (Blind, Right)

The ZP 01.627 reverse half-axle assembly complete with a wheel is a fully integrated right-side running gear drive unit designed for installation on classic ZM-60 grain throwers. The unit mounts to the machine frame using two H 026.058 cast-iron bearing housings and is responsible for the continuous, uninterrupted transmission of torque from the self-propelled gearbox directly to the right driving wheel.

The structural nature of this assembly unit stems from the asymmetric drive layout utilized specifically on single-speed ZM-60 machines featuring a gearbox with an internal differential. Unlike the ZM-60A (which featured a two-speed gearbox without a differential and standardly employed two identical half-axles with disengagement mechanisms), the classic ZM-60 relied on uncoupling the drive solely on the left side to maneuver or relocate the machine. The right ZP 01.627 half-axle was designed as blind—lacking a cam clutch, springs, or disengagement levers.

This factory assembly includes: a solid 30 mm diameter steel ZP 01.627 shaft featuring two keyways and a mounting pad for the ZP 14.502 locking plate, a cast-iron ZM 01.104 hub with a flat face, a ZP 01.360 drive sprocket (Z=25, 19.05 mm pitch) secured via an 8x7 mm key and an M10 set screw, two 11206 spherical bearings within sealed housings, and a ZPT 1.6.2 rubber-tired wheel (400 mm) mounted to the hub flange.

Supplying the right-side reverse gear fully assembled with a wheel enables a comprehensive overhaul of the blind half-axle in cases of wear or deformation—eliminating the need to separately install bearings into housings, align keys, clamp locking plates, and mount tires in the workshop. This dimensionally calibrated unit bolts directly to the frame via housing feet and connects straight to the self-propelled drive chain.

• Wheel hub: Blind cast-iron hub ZM 01.104 with a flat face (cam-free), secured to the shaft via the ZP 14.502 plate using two M8x16 bolts
• Running wheel: 1 rubber-tired wheel ZPT 1.6.2 (400 mm diameter, 6 mm steel disk, pressed-on bandless IZ 2162 tire) complete with M12 mounting bolts

The utilization of the blind ZP 01.627 half-axle is dictated by the self-propelled mechanism design of the early single-speed ZM-60s—these machines housed a differential inside the gearbox, allowing the machine to turn or travel when only the left ZP 01.102 clutch was uncoupled. The right ZP 01.627 half-axle featured no disengagement elements: the shaft transmits rotation to the ZM 01.104 hub via a keyed connection and is additionally locked by the ZP 14.502 locking plate, which bolts directly onto the milled pad on the shaft. Later ZM-60A models adopted a two-speed gearbox without a differential, standardizing two identical left half-axles with clutches instead.

During manual towing or relocation of classic ZM-60 machines, the blind right wheel continued to spin and idled the differential satellites and gears inside the gearbox, generating extra movement resistance and accelerating internal component wear. Consequently, during major overhauls, farms frequently discarded the ZP 01.627 half-axle, replacing it with the ZP 01.625 cam-clutch half-axle to convert the machine to a symmetric running gear.

Today, encountering an original right ZP 01.627 half-axle in working condition is rare, as most machines have been converted to symmetric axles. Nevertheless, for farms and restorers seeking to preserve or restore the classic factory ZM-60 configuration without modern modifications, Zavod Moroza continues to manufacture all elements of this assembly. We supply individual ZP 01.627 steel shafts, ZP 14.502 plates, and ZM 01.104 hubs, as well as fully assembled and calibrated turnkey right-side reverse gear units.

Field Modifications in Agricultural Operations

Although the original right ZP 01.627 half-axle is less common today than cam-type variants, this unit underwent various forced alterations across years of operation. Due to worn threaded holes or deformation of the milled pad, operators frequently abandoned the standard ZM 01.4502 locking plate—securing the hub to the shaft via additional keyways, fastening it with through-bolts directly through the casting body, or even welding it to the shaft.

Thanks to our in-house foundry and machining facilities, Zavod Moroza is prepared to produce both strictly standardized right half-axles featuring the classic ZP 14.502 plate pad according to original blueprints and adapt components to match any mounting dimensions or changes resulting from prior repairs on your machinery.

Buying the Assembled ZP 01.627 Reverse Half-Axle from Zavod Moroza

The expertise of Zavod Moroza specialists builds on a deep understanding of structural characteristics across grain thrower generations—from classic ZM-60s to modern ZM-60U, ZM-90U, and ZM-120U series. We thoroughly understand how equipment behaves under real operating conditions and the structural nuances agricultural engineers face.

Purchasing the blind ZP 01.627 half-axle in a complete factory assembly allows you to restore proper kinematics on the right side of the running gear without lengthy searches for individual parts or complex workshop fitting work. You receive a calibrated unit featuring a properly aligned ZP 01.360 sprocket, secured ZM 01.104 hub, and pre-mounted 11206 spherical bearings.
