产品匹配要点
最终下单前，请结合下列要点和应用车型表一起确认。
如何确认 CF-12251N-1G 是否适配？
请优先比对 Part No、OE 编号、Lester 号、应用车型以及规格表。当前页面的适配信息和规格都是围绕 Komatsu D20, Komatsu D20A, Komatsu D20P and related applications 整理的。
需要重点比对哪些字段？
建议优先看 Voltage: 24V, Amperage: 25A, Rotation: CW, Pulley Class: V1，再结合 OE 编号 Komatsu 600-821-6110, 600-821-6120, 600-821-6130, 600-821-6140 进行交叉确认。
只有图片或局部编号时怎么办？
请提供铭牌、驱动端、插头侧和安装面照片，并尽量附上部分编号或 Lester 号 12251, 12251A, 12251B. 这样更容易缩小匹配范围。
