3646 pushers

Roger F · May 30, 2020

Can anyone help please?
Would a 3646 third execution originally have had smooth pushers ? If so is there a part number or specification that might just help locate some to replace a pair of later ‘ribbed’ pushers that are still in demand
Thanks

Hi Roger, is this in relation to the same Autavia you asked about, that went for auction this week? If so did you end up buying it?

There is no part number per se and these pushers are very difficult to find. If you're lucky you may be able to find round caps which, I believe, are interchangeable withe fluted ones....
Thanks, Steve

Hi Steve
Think I have sourced some so thanks for your help
Just not sure if they are the correct diameter.
Jeff Stein wrote a great post which suggests 4.4mm on the original version but I’m wondering if that’s a bit small as my later 1970s Autavias have 6mm pushers?
Don’t suppose you can help?
Cheers
Roger

Hi Roger, do you mean the pusher cap diameter I assume? 4.4mm sounds about right, the later Autavias would certainly have been larger....
Best, Steve
