Genuine Sinotruk Bolt (Track) 8190-MA-00063 – Unrivalled Strength & Unmatched Durability for Howo Undercarriage Systems

Engineering Excellence Behind the 8190-MA-00063 Track Bolt

The 8190-MA-00063 track bolt is far more than a simple fastener – it is a precision‑engineered component that plays a vital role in the safety, alignment, and longevity of your vehicle’s undercarriage. Manufactured from a premium chromium‑molybdenum‑vanadium alloy steel (30CrMoV), it undergoes a rigorous heat‑treatment process to achieve a tensile strength of ≥ 1040 MPa and a yield strength of ≥ 940 MPa, meeting the exacting requirements of property class 10.9. Its threads are rolled after heat treatment, which work‑hardens the thread roots and significantly increases fatigue resistance – a critical advantage for applications subject to cyclic loading and shock impacts.

The bolt features a serrated flange head that provides a positive locking action, reducing the risk of loosening under vibration. The flange also distributes the clamp load over a wider area, preventing the bolt head from embedding into the track component or frame. The zinc‑nickel coating offers outstanding protection against corrosion, far surpassing standard zinc plating – especially important in Nigeria’s humid and dusty environments where road salt, mud, and moisture can rapidly degrade unprotected fasteners.

In typical Howo truck applications, the 8190-MA-00063 is used to secure track pads, grouser bars, or other undercarriage components. Its precise length and thread pitch ensure perfect fitment, and the bolt’s high clamp load ensures that track components remain firmly attached, maintaining proper alignment and preventing premature wear of the undercarriage system.

Why the Genuine Sinotruk 8190-MA-00063 Outperforms Generic Track Bolts

Generic track bolts are often made from lower‑grade steel with inconsistent heat treatment, leading to premature yielding, thread stripping, or brittle fracture under the high shock loads typical of undercarriage applications. The 8190-MA-00063, with its premium alloy and controlled heat treatment, delivers consistent tensile strength and ductility, ensuring that the bolt maintains its clamp load over thousands of operating hours. Its rolled threads provide a smoother surface finish, reducing friction and allowing more accurate torque application – critical for achieving the correct preload without overstressing the joint.

Moreover, the zinc‑nickel coating on this bolt offers superior galvanic protection compared to standard zinc plating, especially when in contact with aluminium or steel components – a common scenario in track and undercarriage assemblies. This coating also provides consistent lubricity, making installation easier and reducing the risk of galling during assembly or removal.

Advanced Metallurgy for Extreme Durability

The 30CrMoV alloy used in the 8190-MA-00063 is specifically formulated to resist hydrogen embrittlement and stress‑corrosion cracking – common failure modes in high‑strength fasteners exposed to humid environments. Its fine‑grain microstructure enhances toughness, allowing the bolt to absorb shock loads without fracturing, which is essential for components subjected to the repeated impacts of track movement and heavy loads.

Compatibility and Fitment

The 8190-MA-00063 is a direct replacement for the original track bolt in a wide range of Sinotruk and Howo models. Its M16x60 dimensions and 2.0mm pitch match the exact specifications required for track pad mounting and undercarriage connections. Always verify the thread length and grade before installation, and use a calibrated torque wrench to tighten to the recommended 280–320 Nm when lubricated with engine oil.

The 8190-MA-00063 bolt is an essential part of that ecosystem – and with Sinotruk’s original quality, you can be confident that every critical connection will remain secure and reliable.

Installation Best Practices for the 8190-MA-00063

Proper installation of the 8190-MA-00063 is essential for ensuring the safety and longevity of your undercarriage system. Begin by thoroughly cleaning the bolt threads and the receiving hole to remove any dirt, old thread‑locking compound, or corrosion. Apply a thin film of anti‑seize compound or clean engine oil to the bolt threads and the flange bearing surface to achieve consistent torque readings. Install the bolt finger‑tight, then torque it to the recommended 280–320 Nm using a calibrated torque wrench, following a cross‑pattern if multiple bolts are used.

During routine maintenance, inspect the 8190-MA-00063 bolts for any signs of loosening, corrosion, or thread damage. If any bolt shows signs of stretching or corrosion, it should be replaced immediately with a new 8190-MA-00063 to maintain proper clamp force and prevent unexpected failure of the track or undercarriage assembly.

Built for Nigeria – Reliable Fastening in Harsh Environments

Nigeria’s heavy‑duty trucking and construction sectors operate under extreme conditions: high temperatures, high humidity, abrasive dust, and constant vibration from unpaved roads. The 8190-MA-00063 track bolt is engineered to withstand these challenges. Its high‑strength alloy and corrosion‑resistant coating ensure that it maintains its clamp force and structural integrity, even after years of exposure to the elements.

Furthermore, the bolt’s precise thread geometry and flange head design prevent loosening due to vibration – a common issue with generic fasteners that can lead to catastrophic undercarriage failure. By choosing the genuine Sinotruk 8190-MA-00063, fleet operators can reduce the risk of unexpected breakdowns and extend the service life of critical undercarriage components.
