孟加拉采购需求：i-China 凯斯挖掘机前导轮，i-住友 KRA1198 KRA1767 履带导轮总成，i-挖掘机导轮，iimveliso

I'm looking for the idler and a complete track adjuster set for a specific excavator model, and I need to clarify that the grease cylinder isn't necessary for this request. Please ensure the color of the components is black, as that's the preferred specification I require. It would be great if you could provide me with the pricing, availability, and lead times for these parts. Looking forward to your prompt response so we can move this forward quickly. Thanks!
