Genuine-Grade Spare Pin for Tonly (Tongli) Mining Dump Trucks

Built for the toughest open-pit conditions, the TL89029010074 front cylinder lower pin is engineered as a direct replacement for Tonly TL89-series off-highway dump trucks, including the 90-ton class TL890 platforms. It sits at one of the most heavily loaded joints in the front suspension system, where the cylinder transfers massive forces into the chassis every single shift.

Why This Pin Stands Out

Exact OEM Fit — Manufactured to the original Tonly drawing for part number TL89029010074, guaranteeing seamless installation on the front cylinder linkage without modification.
Mining-Grade Durability — Constructed from high-strength alloy steel with heat treatment (quenching & tempering) for superior wear resistance, impact toughness and resistance to deformation under extreme shock loads.
Precision Machined — Tight dimensional tolerances and fine surface finish ensure a proper fit with the bushings, reducing play, abnormal wear and premature joint failure.
Anti-Spin Design Compatible — Works with the pin's anti-rotation features found on modern mining dump truck cylinder linkages, minimizing circumferential rotation and extending service life.
Traceable & Authentic — Supplied with full part-number traceability aligned with Tonly's genuine accessories system, helping you avoid the risks of counterfeit wear parts that cause unexpected breakdowns.

Keep Your Fleet Moving

Downtime in mining costs thousands per hour. The TL89029010074 is a high-turnover wear item — keeping genuine-spec replacements in stock means your maintenance team can swap it fast and get the truck back to hauling.
