Equipment Compatibility & Vehicle Applications
The genuine hexagon bolt (OEM 169900000082A) is a critical component in multiple SANY assemblies. It is extensively used in the SANY Gear Drive Group, which is found in SANY SKT90S, SKT105S, and SKT130S heavy-duty dump trucks, as well as SY215, SY335, SY365, and SY485 excavator models.
Within the Gear Drive Group, the 169900000082A bolt secures the Idler Gear Assembly (Part No. 160102130003A039) and Block, Thrust (Part No. 169900000083A). Three units of this bolt are used per assembly, working alongside other fasteners to maintain precise alignment of the Camshaft Timing Gear and Shaft, Idler Gear.
Beyond the Gear Drive Group, 169900000082A bolts are also used in SANY Engine Bracket Groups, Front End Cover Groups, and various suspension assemblies. In these applications, the bolt ensures reliable, long-lasting connections between the engine and chassis, enhancing overall operational safety.
The bolt’s Grade 10.9 property class provides superior tensile strength and fatigue resistance, making it suitable for high-stress applications such as engine mounting and gear train assembly. Fleet operators worldwide rely on genuine 169900000082A bolts to maintain structural integrity and prevent joint loosening in demanding operating environments.
Installation & Maintenance Guide for 169900000082A
Proper installation of the 169900000082A hexagon bolt is essential for ensuring maximum clamping force and long-term reliability. Before installation, clean the threaded hole thoroughly using a non-abrasive solvent or compressed air to remove any debris or old thread-locking compound.
Apply a small amount of medium-strength thread locker (such as LOCTITE 243) to the bolt threads for vibration-resistant applications. Hand-thread the 169900000082A bolt fully before applying torque to prevent cross-threading. Using a calibrated torque wrench, tighten the bolt in a star pattern if multiple bolts are being installed on the same assembly.
The recommended torque specification for 169900000082A is 80 Nm ± 5 Nm on dry threads. For lubricated threads, reduce torque by approximately 20% to avoid over-tightening. After final torque application, mark the bolt head with a torque stripe to enable visual inspection of any loosening during operation.
Routine inspection intervals of 2,000 operating hours are recommended for critical assemblies utilizing the 169900000082A bolt. Check for signs of corrosion, thread damage, or torque relaxation. If any bolt shows signs of rust or thread deformation, replace it immediately with a new genuine 169900000082A component.
When disassembling components secured with 169900000082A bolts, always inspect the bolt for stretching (measured length increase > 1% indicates permanent deformation). Reusing stretched or damaged bolts is not recommended, as fatigue failure could lead to critical assembly loosening. After each major overhaul, always install new hexagon bolts to ensure proper torque retention.
Always verify the part number 169900000082A laser-engraved on the bolt head. Authentic SANY bolts feature the SANY logo, property class “10.9” marking, and batch traceability code for quality assurance.
