My brother and I are in the process of building a bike with inherited parts. We will be resurrecting a panhead chopper left to us by our older brother who passed away.
Today we started looking at 2 transmissions to decide which we will use. After removing the ratchet tops for both we found on one of the units something that I can only describe as curious.
The top of both shifting fingers just above where the shifting finger roller sits has been drilled and what appears to be a staple ( or something similar ) has been fed through the hole as if to be used as a pin to keep the roller from rising up.
We have no idea as to why someone would go through the effort to drill the finger and have to wonder if it's even possible for the roller to rise up so much that it would need to be pinned to keep it from happening.
I would love to hear any theories, guesses or opinions as to why this was done.
That's what my brother and I were thinking but we thought we might put this thread up just to see if there were any other thoughts. We just can't think of any reason whatsoever to do that.
The early shift stays had cotter pin holding them in place its a throw back but cool to have on an original piece
the third gear will be bushinged - if you dont fix it now and drive it when you hear third gear singing - that is it
Original 3rd gear on the main shaft are not strong - andrews sells a replacement that is all steel i am doing two of those early units this week - if hi gear is original to that unit then it has no seal in its center as well - just know that unit is a leaker but can be fixed but its pricy
in my shop we would make a deal with that sort of extra trans by doing rebuild against the idea one in top condition is worth more then 2 not in usable
The very early shift drum tank shift machine was being moved around with shift locations - first was back hi was up front neutral was one up from back location first - then they moved it the netural in the center - then it ended up at the front one back and stayed - but you also had reverse gear boxes - these units were very parts oriented lots of pieces
your question the top hats were often different lengths not much but it happened - and the shift drum was cut into a flat sheet and then rolled and brazed onto the ends with removable bushings and then it used a shaft in the top cover - mistakes were possible - wear was a thing as the shift lever was driving it from the side - then the ball and spring adjustment and the rods and the shift off the gas tank its self bushing wear all Lent its self to hand abuse jamming it - when this happens **** pops off
most machines were left out side in weather and the roads were dirt in the usa except for big citys - stop and go were all the roads - hi way system was being built in the usa in 1968 < yea
while it all worked advances in machining have added a lot of quality to what we do in restoration shops today and its way better and the cotter pin stay was not needed but its a cool thing to install in an early bushing gear box but everything must be hand fitted or it leaks but you could never tell what was leaking because it was total loss oiling system till 1965 <<<< yea 1965 in FL machines AND 1973 for the W series trikes were dipping oil every place they went - every time but when they stopped leaking you knew it was empty and re filled it
