OEM 6105Q-1005058A The crankshaft thrust plate is a precision component that controls the end-play (axial movement) of the crankshaft, ensuring proper alignment of connecting rods and bearings under the immense thrust loads from clutch actuation and engine operation. The genuine SINOTRUK HOWO 6105Q-1005058A Crankshaft Thrust Plate is an OEM‑grade component engineered for a perfect fit and long‑term durability. As a vital element of the trusted Sinotruk howo parts family, this thrust plate is crafted with high-strength, anti-corrosion materials to bear heavy loads, resist wear, and stand up to harsh conditions—effectively protecting the crankshaft and engine block from premature wear while ensuring consistent performance.
The 6105Q-1005058A thrust plate is typically made from a high-strength aluminum alloy or steel-backed material, precision-cast for durability.
The thrust face is coated with a soft metal overlay (often babbit or similar) that provides a low-friction surface and embeds debris, protecting the crankshaft.
Thickness is controlled to micron-level tolerances to establish the correct crankshaft end-play, critical for preventing bearing and thrust surface damage.
Designed with precision oil grooves that ensure a continuous supply of oil to the thrust surface, essential for handling high thrust loads.

The thrust plate is the component that absorbs the forward and backward thrust of the crankshaft, primarily generated when the clutch is depressed. A worn or failed 6105Q-1005058A thrust plate allows excessive crankshaft movement, leading to misaligned connecting rods, bearing failure, and potential contact between rotating and stationary parts. The genuine SINOTRUK HOWO thrust plate is crafted with high-strength, anti-corrosion materials to bear heavy loads and resist wear, ensuring precise crankshaft location for the engine’s life.
The 6105Q-1005058A thrust plate is produced using precision casting and machining. The thrust faces are finished to a fine surface texture, and thickness is held to tight tolerances.
Every batch of Sinotruk Howo Parts goes through strict testing against international standards (e.g., ISO, CE) and Sinotruk’s original specs. Plates are inspected for thickness, surface finish, and bond integrity of the bearing overlay.
The development of the 6105Q-1005058A Crankshaft Thrust Plate focused on providing a durable and precise thrust bearing surface under extreme axial loads. These plates are subjected to continuous pressure from the clutch and inertial forces. A failed plate can cause catastrophic engine damage. This genuine component is engineered to maintain its thickness and surface integrity for hundreds of thousands of kilometers.
The material and construction of the 6105Q-1005058A are critical. Often, it is a steel-backed plate with a soft bearing metal (like babbit or aluminum-tin) bonded to the thrust face. The steel backing provides strength, while the soft overlay conforms to the crankshaft thrust surface, embeds debris, and provides a low-friction surface. Oil grooves ensure a constant oil film.
Quality control for the 6105Q-1005058A is exhaustive. In addition to 100% dimensional inspection (especially thickness), sample plates are tested for bond strength between the backing and bearing material. Microscopic examination ensures the overlay is uniform and defect-free. Only components that pass all these rigorous checks are approved for shipment as genuine Sinotruk Howo parts.
A failing thrust plate can cause a range of issues. Symptoms include difficulty engaging or disengaging the clutch, a knocking noise from the engine, low oil pressure (due to excessive clearance), and eventually, engine failure. During an engine overhaul, crankshaft end-play must be measured. If it exceeds specifications, replacement with a genuine 6105Q-1005058A thrust plate (often in selective sizes) is required.
Installation requires precision. The old thrust plate halves are removed from the main bearing groove. The new 6105Q-1005058A plate is installed with the oil grooves facing the crankshaft thrust surface. Liberal assembly lube is applied. After torquing the main caps, end-play must be rechecked to ensure it’s within specification.
Field performance of the 6105Q-1005058A thrust plate has proven its exceptional reliability. In a study of over 200 Howo truck engines, genuine thrust plates showed minimal wear within 600,000 km when properly lubricated. This reliability translates directly to reduced downtime and lower operating costs for fleet operators.
For parts managers, the 6105Q-1005058A crankshaft thrust plates are available individually or as part of a main bearing set, each with a lot traceability label. Bulk orders (sets for 10+ engines) receive additional packaging discounts and priority handling. The plates are packaged in oiled paper to prevent corrosion during transit.
Warranty and support for the 6105Q-1005058A are comprehensive. SINOTRUK HOWO provides a 2‑year/unlimited mileage warranty against manufacturing defects. Our technical support team is available via email to answer any questions regarding installation or compatibility, and we are committed to providing a response within 24 hours.
When ordering, always verify your engine model and required thrust plate thickness (standard or oversize). The 6105Q-1005058A is designed for specific applications within the WD615/MC engine family. Using the correct part ensures a perfect fit and optimal crankshaft end-play control, ensuring seamless installation without extra modifications.
In summary, the 6105Q-1005058A Crankshaft Thrust Plate is a vital component for ensuring the long-term reliability and performance of your SINOTRUK HOWO truck’s engine. Its premium materials, precision manufacturing, and rigorous testing make it the preferred choice for thrust control. Trust the genuine 6105Q-1005058A – it keeps your crankshaft in its place.
During engine overhaul, always measure crankshaft end-play with a dial indicator. If end-play is excessive, replace the thrust plate with a genuine 6105Q-1005058A. Use proper assembly lube on the thrust faces during installation.
