148555 Locating Pin High Precision Engine Positioning Dowel Pin For Foton Cummins Diesel Engine

Product Overview

148555 locating pin is a critical precision positioning fitting customized for Foton light and heavy commercial trucks matched with Cummins diesel engines. Installed between engine cylinder block, gear housing and transmission assembly, it provides accurate alignment positioning during assembly, prevents part offset and dislocation under long-term engine vibration.

This positioning dowel pin solves common assembly faults such as part misalignment, assembly gap, abnormal knocking noise and component uneven wear caused by soft, deformed or worn locating pins, maintaining stable matching precision of engine internal assemblies for full-load logistics vehicles.

Core Product Advantages

1. High carbon alloy steel raw material with overall quenching heat treatment, high surface hardness, strong compression and shear resistance, not easy to bend or wear under long-term assembly pressure and vibration.

2. Ultra-precise cylindrical grinding process, uniform outer diameter and smooth surface, tight matching with assembly holes, effectively eliminate assembly clearance and component shifting.

3. Anti-rust passivation surface treatment, resist engine oil vapor, dust and high-temperature corrosion inside engine compartment, keep stable positioning accuracy for long-term operation.

4. Excellent anti-fatigue performance, withstand continuous reciprocating vibration generated by engine high-speed operation, no permanent deformation after long full-load driving.

5. Standard unified outer diameter and length specification, perfectly match Cummins engine assembly hole size of Foton trucks, plug-and-play installation without cutting or trimming.

6. Wide temperature adaptability, stable rigid performance from -40℃ ~ +130℃, no brittle crack in cold plateau or softening failure under high-temperature working environment.

7. Complete batch quality inspection including hardness test, dimensional tolerance detection and vibration fatigue cycle test before delivery, consistent stable quality for repair shop replacement and fleet bulk procurement.
