Wheel Rim ZPT 1.6.2.1 ZM-60/60A

Wheel Rim ZPT 1.6.2.1

The wheel rim ZPT 1-6-2-1 is the main load-bearing element of the support system of the ZM-60/60A series grain loaders and their modifications, serving as a rigid metal base for installing the outer massive tire (usually IZH 2162). In the unit's undercarriage, this part performs the function of a power connecting link between the hub and the rubber coating, where it is precisely the steel rim that takes on the significant weight of the massive machine and lateral loads during turns, transmitting them from the rotation axis directly to the working tire. The reliability of the wheel fixation, the absence of run-out, and the stable, uniform travel of the grain loader during operation and intensive maneuvers on the threshing floor directly depend on the correct geometric shape, the quality of the weld seams, and the overall strength of this metal disc.

Design Features and Technical Specifications of the Rim ZPT 1.6.2.1

• Catalogue number: ZPT 1.6.2.1
• Material: sheet structural carbon steel (St3)
• Metal thickness: 6 mm
• Quantity per unit: from 1 to 4 pcs. (depending on the undercarriage configuration)
• Country of manufacture: Ukraine

Structurally, the product is a solid welded metal structure consisting of a central support disc and an outer cylindrical ring welded to it - the direct base for the rubber tire. Thanks to its well-thought-out geometry and a high-quality weld seam, the rim has high spatial rigidity, which excludes its crumpling under the weight of a static or operating grain loader. Standardized mounting holes are made in the central part of the part, which guarantee exact centering of the disc on the hubs of the front or rear axle without misalignments. The outer surface of the support ring has a strictly verified diameter and a smooth texture, specially calculated for the tight mechanical interference press-fitting of the massive IZH 2162 tire or the application of rubber by the hot vulcanization method - such manufacturing precision prevents spontaneous slipping or rotation of the rubber coating during unit turns, effectively eliminating a typical vulnerability characteristic of worn discs of old machines.

Features of Repair and Replacement of the Metal Rim ZPT 1.6.2.1

The need to replace the metal disc most often arises as a result of serious mechanical deformations. When running over significant obstacles or working on uneven surfaces with a full load, the rim can receive a geometric warping - a so-called figure-eight. Another common problem is the battering of the mounting holes into an ellipse, which happens due to the prolonged operation of the unit with loosened wheel bolts. Less often, but there are cases of fatigue metal cracks along the weld seam line between the central disc and the outer ring.

Attempts to straighten a deformed 6 mm steel disc with a sledgehammer or by heating in garage conditions extremely rarely return it to its correct geometry. Installing such a "repaired" rim will lead to risks of run-out during movement, which will very quickly destroy the roller or metal-ceramic bushing of the hub and transmit vibration to the load-bearing frame. Therefore, replacing the disc with a new one while maintaining perfect centering is the only technically sound way to restore the normal kinematics of the undercarriage.

It is also worth understanding a practical nuance of the replacement process - buying a bare metal rim ZPT 1.6.2.1 is advisable when the old steel base has failed, but the existing rubber tire is not yet worn out and is suitable for further use. However, high-quality press-fitting of a rigid bandless tire onto a new disc requires a hydraulic press, and if there is no such equipment in your workshop, attempts to pull the rubber on with improvised tools can lead to its misalignment and subsequent slipping off during operation or maneuvering. In this case, it is more rational to consider the option of replacing the ZPT 1.6.2 wheel completely as an assembly by turning to ready-made factory solutions. We ensure perfectly even press-fitting of the tire on hydraulic equipment or apply the hot vulcanization method, which fixes the rubber to the metal disc "dead" - thanks to this, you will only have to bolt the finished assembly to the hub and calmly continue operation, forever forgetting about the risk of the tire slipping off.

Buy the Steel Wheel Rim ZPT 1.6.2.1 for ZM-60 at the Moroz Plant

A reliable support base is a guarantee of confident maneuvering of the grain loader across threshing floor sites and its stable, uniform travel during operation. The metal rim ZPT 1.6.2.1 from the Moroz Plant is manufactured preserving strict geometry and using high-quality 6 mm steel, which guarantees high resistance of the disc to deformations even during turns of the massive machine. Thanks to the standardized bolt pattern of the mounting holes, this part is absolutely versatile and easily aggregates with the front or rear travel hubs of the classic ZM-60s and their modern modifications.

We offer the most rational approach to repairing your equipment - depending on whether you have an undamaged tire and pressing equipment, you can order either a separate metal rim ZPT 1.6.2.1 or a fully equipped rubber-coated wheel assembly (ZPT 1.6.2).
