    Default Military oil bath air cleaner

    Looking for some reference pics for the short round oil bath air cleaner on military Indian motorcycles. Any body have some pics they would be willing to share? Thanks!

    I also have 741 project and took these reference pics at Oley this year. Bike was presented by owner as his fathers unrestored original paint 741.I have also seen the round air cleaner and believe either is correct but don't know for sure.

    I believe 741's used both the short round ones as well as the square ones and the 340 and 344's used the tall round air cleaners. Focusing on the round ones as I have a non MC one that I may be able to convert. Looks like I'm just going to have to find one that I can compare them two side by side. Thanks everyone!

    I found this pic online. I was thinking about putting a round one on my 640B but may not be worth the effort.

    Based on the pics in Tech manual Robbie posted it appears the round and improved square type also use different carb adapter and hose.
    The red bike seems to have a mismatch custom combination of the two types

    The manual shows a 640 while the red bike may be a 741?

    I think the red scout is not a 741,based on the primary drive mag drive cover and the rear frame strut,but I am no expert.
