M543A2 Vs M813 Intake Air Units?

[rumplecat]

I have an extra Air filter unit(M813 Fender Mounted?), the unit on my M543A2 is in poor shape(Rust) are they interchangeable? Are they the same size, they look to be but I don't have it here with me. Filter are different I think but size and bolt arrangement is the question!

They are not inter changeable. The filters add a lot of weght and stress on the fenders. The 813/16 have a much stronger brace under the fender to accomidate the extra weight of the filter can. I'm having a hard time finding filters now for my M 54's and I don't know if there is a civi replacement number. I'm sure someone here has found a source but I haven't.

I hope this is not an 800 series housing, the guy I got it from was not sure what it came off of, I need to measure!

The picture is not of a 809 series air filter the intake on them is out the side of the can not the end, not sure what can you have there.

The filter housing in the pics is the same as the M39 series with the mack or multi.

You must not be looking very hard.

The M809 series air cleaner assembly could be adapted to fit a M39 series it would not be that difficult to do !! As for your photo that is a M39 series air cleaner assembly. as for your filter element i bet you can be cleaner if you find a local filter cleaner that cleans air filters.
