Hi, I am now trying to put my seat together from a bag of unmarked parts (it's a '31). Looking at the R&O Manual I seem to have all the bits but I am puzzled how the bronze bushings fit into the springs. I assume the smaller diameter end of the bushing fits in the hole in the bottom of the large spring and the small spring fits over the top of the bushing but this is a loose fit and I can't see what retains the bushing and prevents it sliding up the yoke.

My bushings may have been turned up by a previous owner as they look slightly different to those in the manual; The manual illustrations show a dished recess in the bottom of the bushing - mine don't have this (is this designed to crush and thus retain the bushing?). Mine are simply a 3/4" brass cylinder 1 1/4" long with reduced diameter of 1/2" at what I assume is the bottom. The internal diameter is 7/16" and the outside diameter of the reduced section is 5/8" measured with a rule.

Any help would be welcome

Thanks

Looking at the (1928) parts book (and R&O Manual) it seems that there are only 2 washers, also my bag of seat parts came with two washers which fit the smaller diameter part of the bushing and one washer that fits over the wider diameter part of the bushing. So to be clear should the washer on the inside of the spring be exactly the same dimensions as the washer on the outside of the spring and fixed (i.e. riveted) in place or should the step in the bushing hold the bushing in place once the bushing is riveted and then  the inside washer be free to move up and down the bushing inside the spring? The 1931 parts book is unclear as it seems  the spring and bushing were supplied assembled (if I have interpreted it correctly).

Thanks
