HELP, shift linkage question
« on: November 14, 2009, 01:36:35 PM »
Hi there, has does anyone have any tips or tricks on how to reassemble the shift mechanism.  I can't seem to find a way to get the springs hooked back onto the two arms with rollers that rest on the end of the shift drum.  I've been trying for hours, but I cant get the springs hooked up.  I have been reading, and noticed that nobody else has complained about getting the shift mechanism back together, so I am assuming that there must be a way to do this.  If you have any experience with this, please let me know.  BTW, I'm working on a 77 CB750F.

Thanks,
-Matt

i assembled mine,spring and all, then bolted it in place, gently putting pressure on the spring as needed to make it all connect. 
go slowly

+1 go slowly. Can't remember it being too much of a problem when I did mine, but probably worth waiting until you're finished before cracking open a beer! Here follows (I hope!) some pics of my stripdown which you may find helpful. Good luck!

Okay, I'm bumping this thread back up as I have a further question on this.

I have not disassembled my shift drum as you have (and hope to not have to). What would you suggest for me? I've done it a couple of times and have skinned many knuckles each time. How should I proceed?

Are they any tricks out there that will help?

... no one wants to help...  :'(

Well, time heals all wounds... and skinned knuckles... I'm heading out into the garage to to try and get the shift linkage back in place. I will take my time and curse as little as possible.

I just had linkage apart yesterday to get the rear most spring back in place, as it was causing some shifting problems for me.  I did all mine by hand slowly.  The springs are not that hard to overcome with fingers.  Plus just keep refering to pictures in this thread, that's what I did (also how i realized I had a spring out of place) these pictures are great.

Also I left the pins and cover on the drum when I did this, first I got the inner spring and arm on first, it was a little tricky but once in place it sorta stayed by it self.  Then I put the outside arm and spring on (alot easier then the inner one) then i put the nut back on, as i tightened it up i kept moving the inner arm until it fell in to place.  Now it hits and stays in every gear (something it has not done before) :).

I hope some of this will help, good luck

Yeah, I just had sucess getting it all in place as well. It went much easier than I thought it would. It's the inner most spring that is a pain. BUT, all is in place. Slow and steady - and a cool head - wins the race. ;)


You're right, though, about the pictures. What the heck did we do before HTML code, picture posting and message boards?!?!?  ;D ;D

I'm glad all went well for ya.  Now that I have my bike straightened out and shifting right it is a blast to ride.  Too bad the weather is turning away from riding weather, oh well there is always next spring :D.  Without the forum I stil think I'd be scratching my head about what was wrong, all my answers have come from here. :)
