Re: Komatsu PC05-5 Yanmar 3D72-2B 3TNA72 engine cross reference Never really thought of a refer unit. I guess once I get the big question of if the komatsu 3d72-2b is the same as the yanmar 3tna72 then it will be easier to begin looking. I haven't found a single person who owns a komatsu that can tell me anything. The dealers act like its top secret or something and don't even tell me if they can get parts with me using their oem number. Its like a headache that just doesn't go away lol. |
