Genuine SINOTRUK Locating Pin 080V91301-0112 - Precision Engine Alignment Component

This OEM Genuine SINOTRUK Locating Pin (Part Number: 080V91301-0112) serves as a critical precision alignment component specifically engineered for HOWO truck engines and transmission systems. Crafted from case-hardened chromium steel through CNC machining processes, this dowel pin guarantees exact component positioning between engine blocks, gearbox housings, and major assemblies. The pin features a slight chamfer on both ends to facilitate installation while maintaining tight dimensional tolerances that prevent movement under vibration and stress. With its zinc-nickel electroplated surface finish, this locating pin offers superior corrosion resistance even in harsh operating environments. As a genuine SINOTRUK part, it ensures perfect fitment and maintains factory-specified alignment for optimal powertrain performance and longevity.

Installation Notes:

1. Thoroughly clean the pin bore using appropriate cleaning tools and verify hole dimensions before installation

2. Apply minimal moly-based lubricant to the pin shaft to prevent galling during installation

3. Use an arbor press or precise hydraulic tool for installation - avoid impact tools that may damage precision surfaces

4. Ensure the pin is driven straight and seats fully without binding or cocking in the bore

5. Verify component alignment before proceeding with final assembly and torque procedures

6. Never attempt to reuse a previously installed locating pin

7. Check for proper fit - the pin should slide into the mating part with slight hand pressure

8. Replace immediately if any visible damage or deformation occurs during installation
