Shimano Trinidad 20 DC - Spool Tension Issue

[oldmanjoe]

  If you post more pictures , both sides of the spool would help.

Is this  the schematics ?

I have the trinidad 30DC this is mine  https://alantani.com/index.php/topic,34090.msg402640.html#msg402640

after looking at my pics I found it pretty hard to believe the spool shaft moved by itself while storaged, maybe the bearings on the sideplate or the bearing on the spool seized and caused the problem.

yep, pics of the both sides of the spool will help

Trust me I find it hard to believe also! This is why I'm lost for ideas.

Spool photos attached.

It would be great to if I could compare measurements between my spool and another Trinidad 20DC. That would eliminate this theory. But they aren't exactly easy to come by. I do appreciate all the help/input and questions. Promise after this I'll post up my other Japanese unicorns hahaha

Also this is evident as the Spacer B on the Left side plate has a mark on it from the spool. So there is pressure there.

did you tried taking the spacer B out and see if the spool has enough space to fit with no pressure?

That was going to be my next question ,  Also is the spacer b a flat washer or concave/convex ?

With out the spacer everything moves freely.
I took spacer B out originally and thought id fixed it. But with out the spacer there is to much Lateral Movement and the  Shaft and pin dont engage with the Pinion Gear (TGT1299) properly, letting it slip under load.

The spacer is flat and 0.7mm thick. Alternatively I try and make a thinner spacer and see if that works. Not sure how thin I can go with out it bending or flexing under load.

OK  At this point ,  I would try just the bearing on the shaft and see that it seat down to its shoulder .  Also double check that the right side bearing is fully seated .   I know you are looking for .025-.027 thousands of of inch .

Ok so update, I've checked and done everything with no success everything is moving and working as needs be, yet the spool is still tight.

So next step was to make a new spacer. Went a thinner spacer B and victory!!! spool is moving freely and no pressure or play. I also lightly polished the end of the spool shaft in case there was a lip or edge (there wasn't), So my verdict is that the shaft has moved within the spool.
I really don't have another logical answer. How or why, it moved, if it actually did. Moisture in the spool from storage? I have no idea.

OK the new shim gave you some clearance .  But like you stated ,Shaft and pin dont engage with the Pinion Gear (TGT1299) properly, letting it slip under load , is still a potential problem .
      I would tighten the drag and try to get the spool to slip on the shaft .   I believe you are right in saying  ;  This is going to be interesting! Im really starting to believe that the shaft has moved inside the spool. At this stage its the only logical answer based on elimination.
