This often occurs if the piston rings were not seated correctly or if the cylinder liner was not honed. Our kits feature OEM-standard tri-metal structures to ensure perfect sealing. Trusted by repair shops & equipment fleets, we recommend checking the 123907-22050 pin fitment as well.
While the bore is 106mm for both, the combustion chamber design (piston crown) varies. Always use the specific part number 123907-22081 for NV models to ensure correct compression ratios and avoid engine knock.
Ensure the 123907-22050 pin and piston skirt are pre-lubricated with clean engine oil. Cleanliness of the oil pump and oil passages is vital for the 4TNV106 cooling jet system to function.
