I’m trying to find the location of my serial number to let my local dealer order a part for me. I have a leaking upper hydraulic cylinder. I told the dealer it’s a Type L4400d, serial number 52117. These number are on a small tag located on the frame, just in front of the starter. The local dealer said there should be another number somewhere(I really couldn’t understand where he was saying) that will tell me what engine I have. Can anyone tell me where the correct serial number is located?
