ZP 01.627 Reverse Half-Axle Assembly (Blind, Right, Without Wheel)

ZP 01.627 Reverse Half-Axle Assembly (Blind, Right, Without Wheel)

The ZP 01.627 half-axle assembly without the wheel set represents an integrated mechanical drive unit for the blind axle designed for classic serial ZM-60 grain throwers. The mechanism mounts to the lower frame rails using two H 026.058 cast-iron footed housings and provides continuous, uninterrupted torque transmission from the self-propelled gearbox directly to the wheel hub.

The defining feature of this supply option is the exclusion of the ZPT 1.6.2 rubber-tired wheel and its mounting fasteners (M12 bolts). However, the assembly ships complete with a blind cast-iron ZM 01.104 hub featuring a standardized square 4-hole flange. This solution is practical for farming operations where old wheel rims and tires retain their working service life, or when installing reinforced 500 mm OVS-25 cleaner wheels or pneumatic tire disks is planned. Ordering this assembled mechanical block enables you to restore the right axle drive without extra expenses on tire rubber and without wasting time assembling all associated small components.

Technical Specifications of the ZP 01.627 Half-Axle (Blind, Without Wheel)

• Assembly designation: ZP 01.627 Reverse Half-Axle Assembly (Configuration without wheel block).
• Purpose: Right drive half-axle with a rigid, continuous connection (without a disengagement mechanism).
• Application: Classic single-speed ZM-60 grain throwers (featuring an internal differential).
• Power shaft: ZP 01.627 shaft (30 mm diameter, Steel 35) featuring two 8x7 mm keyways and a milled longitudinal pad for the locking plate.
• Support assemblies: 2 cast-iron housings H 026.058 (Sch 20) with mounting feet for bolted frame attachment.
• Bearing kit: Spherical double-row bearings 11206 (1207K + H207 tapered adapter sleeve set) — 2 pcs.
• Bearing chamber seals: Through cast-iron covers H 026.163 with fitted lip seals (30x52 mm oil seals) — 4 pcs., grease fittings.
• Drive sprocket: ZP 01.360 (Z=25, pitch t=19.05 mm for PRL-19.05 chain) mounted on an 8x7 mm prismatic key with an M10 clamping set screw.
• Wheel hub: Blind cast-iron hub ZM 01.104 with a flat face (cam-free) and a 4-hole flange.
• Locking element: ZP 14.502 locking plate with two M8x16 mounting bolts.
• Wheel inclusion: Excluded (supplied without the ZPT 1.6.2 wheel and M12 wheel bolts).

Torque transmission within this unit follows a rigid, continuous layout: rotation from the self-propelled chain is accepted by the ZP 01.360 sprocket and transferred via an 8x7 mm prismatic key to the steel ZP 01.627 shaft. The M10 set screw inside the sprocket hub secures the part against axial displacement. Furthermore, torque travels via a second key to the ZM 01.104 hub, which is additionally locked onto the milled shaft pad using the ZP 14.502 steel plate and two M8x16 bolts—establishing a mechanical lock that guarantees stable right-wheel travel.

The support block consists of two H 026.058 cast-iron housings. Internal 11206 bearings self-align within their seats via the spherical raceways of their outer rings, compensating for shaft deflection and frame bending under lifting and loading stresses. To protect against abrasive grain dust, the bearing chambers are sealed with H 026.163 through cast-iron covers equipped with 30x52 mm reinforced lip seals.

The evolution of the blind ZP 01.627 half-axle with the ZM 01.104 hub applied exclusively to classic single-speed ZM-60 grain throwers. Their self-propelled gearbox design incorporated an internal differential, meaning that for turns or towing, the drive was uncoupled solely on the left side (at the ZP 01.625 shaft) while the right half-axle remained permanently locked. Later ZM-60A models adopted a two-speed gearbox without a differential, requiring two identical half-axles with clutches, whereas our modern ZM-60U and ZM-90U grain throwers utilize a two-speed gearbox with a differential and standardly mount two symmetric ZP 01.625 cam half-axles, enabling both wheels to uncouple and fully relieving transmission loads during towing.

Interestingly, during extended operation of classic ZM-60s, threaded holes on the ZM 01.104 hub or the milled shaft pad frequently experienced wear. In farm repair shops, mechanics often discarded the ZP 14.502 plate—welding the hub, cutting extra keyways, or securing it with through-bolts directly through the casting body. Zavod Moroza manufactures both strictly standardized serial ZP 01.627 half-axles according to original blueprints to preserve the factory asymmetric drive and adapts components to match altered parameters of restored machinery. If your machine's mounting seats or hub holes underwent prior modifications, we can rebore the part or manufacture a shaft and all associated elements to your exact specifications.

Buying the ZP 01.627 Reverse Half-Axle Assembly (Without Wheel)

Zavod Moroza's expertise builds on a deep understanding of the design and practical application of grain throwers across all generations—from classic ZM-60s to modern ZM-60U, ZM-90U, and ZM-120U series. We understand all technical nuances of these machines and provide reliable solutions for rapidly restoring their operational capability.

Ordering the right ZP 01.627 half-axle assembly without the wheel allows you to overhaul the blind drive without unnecessary expenses—you receive a fully assembled, factory-calibrated unit complete with a set ZP 01.360 sprocket, secured ZM 01.104 hub, and pre-mounted 11206 spherical bearings. Commissioning requires simply securing the H 026.058 housings to the frame, bolting your existing wheel to the hub flange, and slipping on the drive chain.
