Cover ZS 4040 of Front Travel ZM-60/60A

Cover ZS 4040 of the Front Travel ZM-60/60A

The cover ZS 4040 is a protective element in the design of the wheel assembly of the classic front travel of the ZM-60/60A grain loaders. In the general scheme, it covers the end face of the hub ZPT 1007, performing the function of a dust barrier. Located on the outside of the wheel assembly, directly behind the thrust washer ZS 4041, this cover "seals" the internal space. It reliably protects the roller bushings (bearing assembly) from the ingress of abrasive grain dust, dirt, and moisture, which is critically important for the durable and uninterrupted rotation of the wheel.

Features and Associated Parts of the Cover ZS 4040

• Catalogue number: ZS 4040
• Purpose: Dust and moisture protection of the internal cavity of the hub
• Material: High-quality sheet steel (stamping)
• Part weight: 0.050 kg
• Quantity per unit: 2 pcs.

Over time, the thin metal cover can deform or get lost. Most often, it receives mechanical damage during the dismantling of rusted assemblies, when it has to be knocked out or roughly pried with a tool. Also, in case of critical wear or the absence of the internal thrust washer, the cover can simply rub through from the inside due to friction against the roller bushing. Usually, its condition is checked during scheduled maintenance of the hub.

To ensure the correct and durable operation of the entire wheel assembly and avoid dirt ingress, it is always advisable to replace this cover in conjunction with the following adjacent parts:

• Washer (ZS 4041)
• Roller bushing (32x48x65)
• Hub ZPT 1007

Scheduled repair of the hub is a good opportunity for targeted improvement of the entire assembly. In particular, the standard roller bushing can be replaced with a wear-resistant ceramic analogue, which minimizes friction force. However, to fully solve the problem of rapid wear of the undercarriage, it is advisable to switch to the modernized two-wheel front travel developed by us - this configuration does not involve the use of the vulnerable stamped cover ZS 4040 and the thrust washer ZS 4041 at all. The protection of the bearing block here is implemented through a reinforced thick-walled washer-cover, which is fixed directly to the axle using a bolted connection. Such an engineering solution completely eliminates its deformation or loss during operation and significantly facilitates current maintenance of the undercarriage.
