    I have a 621B with serial number prefix 8HC. Is this prefix close to or the same as the other standard prefixes that I see on available shop service manuals? This machine is ex-military and I am not sure if the components are all the same for this machine prefix as those with another prefix. For example, given this machine was built mid-late 80's would it be closest to a 45P prefix?

    That might be a question Cat could answer better.

    But just for fun I looked at "TRANSMISSION ARRANGEMENT" for both those prefixes and despite the arrangement numbers being different the list of components in them seem to be the same.

    If there was a particular item you wanted to compare that might not be too bad, but I would guess that if one was made for military use there would be some options a civilian unit might not have or there could be something left of the military version.

    8HC is a military 621B wheel tractor, commercial equivalent 45P3594.
    Might have a 9AC scraper commercial # 36V2350.

    I thought that 45P might be the closest in relation given the year it was made. Great answers. Thank you.
