B322167 Carbon Brush with 20-25-45 size reference supports electrical contact renewal for B2B excavator parts repair and wholesale sourcing.
The B322167 Carbon Brush YNF17699 is a replaceable electrical contact component used in compatible construction machinery electrical equipment. Carbon brushes are commonly installed where electrical current must be transferred between a stationary circuit and a rotating component through continuous sliding contact.
The supplied product carries a 20-25-45 size reference, which should be compared carefully with the removed brush before replacement. Brush dimensions, lead arrangement, terminal style, spring configuration, and contact-face shape can vary even when products appear similar.
For B2B buyers, the B322167 carbon brush should be verified by reference number, physical size, carbon block shape, electrical lead position, terminal design, and existing-part photos before quantity purchasing. Accurate dimensional comparison is especially important when no specific machine model or electrical-unit reference is supplied. Correct verification helps repair businesses and wholesalers reduce incorrect stock, premature installation problems, customer returns, and unnecessary international freight.
