how to mount the spring of the reefing-line jam-lever in the forward boom end-fitting of a Selden B171 boom? We fiddled around with it for an hour but in the end the spring popped out again.
We have a Selden single-line reefing system for two reefs & want to have the option of a third reef (not possible as single-line, obviously) that we plan to tie "traditionally" with a clew-reefing-line jammed with a lever at the forward boom-end-fitting & a luff-cringle on a hook. We got a lever with it's half-bushes & a spring, the axle for it (strange: the hole in the lever even with the bushes is noticably bigger than the 10mm axle), fished the 3rd reefing line successfully through the boom (no mean feet what with 2 single-line-reefing sliders & the outhaul-tackle-slider in there...) - but no success with the spring! anybody done it?

...nobody having post-2008 Selden jam-levers who could take a look at them???

OK, I have not, but in case you haven't seen it, here is some info. Perhaps you are missing a piece in there?

thank you Don.
I have all the pieces on the drawing-just the exact position of the spring & how to get it there eludes us...

OK, I'll just take a stab at it given what I see, but you have probably tried this already...
I believe the hook inside is to be placed first, and this may be the tricky part I grant you. You might need to make a tool that can hold the spring and pivot it up to the right angle to be able to hook it on the hole provided for it. Then I believe it may be easier to attach the spring to the lever before sliding it up into place and then sliding the pin into it, Given the sheave and washers in there, that could be tough. (I hear you laughing now I think.) Is the boom currently attached to the mast? Can you remove it to lean it on its side? I wonder if that would help hold the sheave and washers from falling out while you slide the lever up in there?
Ok I am flying blind here without holding the thing in my hands, but maybe someone with experience will chime in.
Any photos of it?

our stuff is more recent then the one in Don's pdf, but lever & spring are pretty much the same - see attached drawing
what baffles me: there are only 3 axes:
the lower forward one for the sheaves leading the reefing lines & outhaul down, the lower rear one for the levers (or for the springs? but then where do the levers go?) & the upper axis for the single line luff-reefingline-pennant sheaves & the smaller outhaul-tackle sheave
we got all pieces in the drawing, well only one lever & one spring, but that shouldn't matter.
the way the spring hooks into the lever seems obvious to me, seems only one position is possible, the rolles part of the spring will definitely not go into the hole of the lever...
(another IQ-test I failed...)

forgot the drawing...

I doubt the correctness of the drawing somewhat:
on the forward axis definitely the pulleys should go & not the springs...

So the springs must still have a mounting point, unseen in your schematic there, but similar to the pdf I sent. Wish I could see a photo looking up from the bottom inside. The photo I attached, is that the same as yours?

your boom endfitting is the older longer style, but I'm sure the levers & springs are arranged in the same way
here a pic of ours
the rear axle had to be shortened because of the eybolts for the kraut-mainsheet system

**Don C L** · 28-07-2018, 10:04

Well, as I said, I am just taking a stab at it.... because now looking at your pic I don't see how the spring mounts and I am stumped. Sorry, wish I had the answer. It would be nice to see how the spring fits into the lever.

This is my old style 171 don't know if it will help

double u · 29-07-2018, 10:33

yep helps, B-Baysailer, same system! our spring must have popped out because of the considerable play between lever & his axle (yes, we used the 2 flanged half -bushes
