I think someone kept putting too much grease on the bearing or started pumping in grease thru the oil filler cap to try and get 4th gear to work. Big time mistake.

Only lost two more springs getting the hub together (5 all told!). These two pawls are the same for the 3 speed and are relatively easy to fit.


It is the other two giving the fourth gear that I struggled with - on the left of the planet cage in this foto. Here they are the wrong way round and I had to do it all again! Note the LHS axle end has the indicator showing fourth gear.


The split indicator rod was something I wasn't familair with. It had a expanding compensator spring between the two that you had to compress to screw them together form either end of the assembled hub.


And so it was in the beginning. Interesting for me to learn something new - you fix the RHS (sprocket side) bearing cone first ( quarter turn back from finger tight) and then you do the non drive LHS. For some reason I found this counter-intuitive but there you go.


Some folks do it in an hour, I take at least a day.Strumey Archer 1945 FW4 hub, 40 Stainless steel spokes, 4 Cross pattern spoke laced under the third spoke and over the forth to give more strength. 1940 stainless Raleigh 26x1 3/8 rim.
