    Curious to any differences between the Mark 3 oil pump and earlier Commandos.
    I see that there are 2 different part numbers.
    Or is just the oil pump rubber sealing washer different?

    The spigot that seal sits on is different, as in larger diameter, to support the larger seal.

    the oil pumps have two different parts numbers but AN supersedes the older number.

    new 06-6193

    I noticed the older pump I was going to use on my MK3 has more rough casting after the machined seal retainer area. No problem with older bikes that use the smaller dia seal . But with the MK3 that causes the larger retainer not to sit properly flush. A little grinding is in order.
