ZP 14.502 Locking Plate

ZP 14.502 Locking Plate for Grain Thrower Reverse Gear

The ZP 14.502 locking plate is a small yet essential running gear securing element utilized in the ZP 01.220 reverse gear mechanism of classic serial ZM-60 grain throwers. The component is designed to create a solid, unbroken connection between the driving half-axle (the ZP 01.627 shaft) and the wheel hub (ZM 01.104) on the right side of the machine.

Thanks to its design, the plate functions as a locking element: it rests upon a specialized milled flat on the shaft and is bolted directly to the hub flange using fasteners. This eliminates relative rotation of the half-axle inside the wheel, ensuring a continuous, rigid transmission of torque from the self-propelled gearbox to the driving wheel.

Technical Specifications of the ZP 14.502 Plate

• Catalog number: ZP 14.502
• Application: ZM-60 (classic models with asymmetric drive)
• Installation assembly: Rear drive ZP 01.220 (fixed half-axle)
• Purpose: Rigidly fixing the ZP 01.627 shaft within the ZM 01.104 wheel hub
• Material: Ordinary quality carbon steel (St 3 GOST 535-79)
• Fastening method: 2 bolts M8x16 (GOST 7796-70)
• Part weight: 0.060 kg (60 grams)
• Quantity per assembly: 1 pc.

A simple rectangular form featuring two mounting holes ensures maximum reliability and compactness. The plate is manufactured from flat bar steel stock, and the center-to-center distance of its holes matches the layout of the threaded holes on the flange of the ZM 01.104 hub precisely.

Fixation against the milled flat of the shaft is the core operating principle of this component within the running gear assembly. The edge of the plate is laid over the longitudinal flat of the ZP 01.627 shaft and clamped down by two M8x16 bolts passing through the hub flange. This creates a mechanical lock that prevents the shaft from rotating, ensuring reliable drive operation without the use of moving clutches or springs.

Associated Spare Parts for the ZP 14.502 Plate

Within the reverse gear mechanism, the ZP 14.502 plate operates within a tightly fixed set of components. During replacement or inspection, the following adjacent parts should be checked:

• Reverse shaft ZP 01.627 — half-axle featuring a milled flat for the plate
• Wheel hub ZM 01.104 — blind cast-iron hub with matching mounting holes
• Fastening bolts M8x16 (GOST 7796-70) — 2 pcs.
• Spring lock washers (growers) 8.65G — to prevent bolt loosening from vibration

Because this plate operates under continuous alternating loads and vibrations generated as the wheel rolls across uneven threshing floors, the holes within it or the mounting bolts may eventually elongate or wear out. Loosening of the tightening torque leads to hub play on the shaft and accelerated wear on the half-axle's milled flat.
