Miller breaks down their machines primarily by model name and in some cases further breaks things down by serial number.
If you have your serial number start with it. Serial numbers since 1973 all start with two letters, then have six digits, and most recently end with a single letter. For example MB1234456F.
If you machine is older than about 2000 (your serial number starts with something other than "L" or "M") Miller may not have the serial numbers indexed for searching. In this case you must start with your machine's name and you must use all of the name. For example a family of engine drives is the Bobcat but there are many different ones--Bobcat 225, Bobcat 225G, Bobcat 225G PLUS, etc and they are all different.
Once you enter your information and hit "Search" it will come back with you manual choices. If you download the manual there is no charge and you can save it to your computer in PDF format or you can order a paper copy but they typically cost $15.00.
Once you find your part give us a call and we will check for superceded numbers, availability, and your cost. As always, if you have a problem just give us a call.
