FAQ

Q1: How can I confirm this dowel pin is the correct one for my Komatsu 6D108 engine?
A1: The best way to confirm fitment is to compare the physical dimensions (diameter and length) of this dowel pin with the original part removed from your engine. Additionally, check for the OEM part number stamp on your original pin, which is often a number like 8-98023-526-0. If you have your engine serial number, you can also cross-reference it in a Komatsu parts catalog.

Q2: What is the function of this dowel pin in the engine, and what happens if it fails?
A2: The dowel pin is used for precision alignment of engine components, such as the cylinder head to the engine block or timing gear housings. It ensures that these parts are assembled in the exact correct position. A worn, damaged, or missing dowel pin can cause misalignment, leading to accelerated wear of gears, bearings, gasket failure, or even severe internal engine damage. It is a critical part for maintaining engine integrity.

Q3: Can I use this dowel pin in other Komatsu engine models besides the 6D108?
A3: While this part is specifically specified for the 6D108 model, some dowel pins are used across multiple engine families if the dimensions are identical. We cannot guarantee fitment for other models. We strongly advise you to measure your existing dowel pin and compare it to the OEM size specifications for your particular engine model to ensure a safe and correct fit.
