my problem now IS,i can't engage reverse all of a sudden....1-2-3-4-5 all ok except for reverse....even after shutting down d engine n tried 2 engage reverse oso kenot.....

i'm running a YS1 gearbox(cable type) on a small v B16A.....

mechanic took d car...lifted it up...took out d linkage n tried 2 engage reverse by grabbing d lever on d gearbox...KENOT!!!!

ur 5th n reverse syncro kong edi....

hmm.. I thought I posted a reply here. Strange that it's missing.

I thought the the reverse gear is straight cut and syncho-less, so can always 'force' a shift (at VERY slow speedla).. a lot of noise and grinding, but always can shift in reverse.

I think maybe something got stuck in the reverse mechanism.. likely the lever (is it called selector forks for the reverse also?) that moves the idler gear.

It would seem that would prevent you from getting the shifter into the R position.

if syncro kong, usually you can shift in into position, but since the syncro has no more teeth (dog teeth/gigi anjing, they call it, I think?), your gear will make sound, but the car won't move.. :P

 

[shiroitenshi]

Eh.. akuma.. forgot to mention I also usually misshift on third lol.. Nowdays I don't let off the clutch so fast, so doesn't happen as much.

That's why I know sure kantoi on 1/4 mile.. but want to join anyway for happy happy fun times. :P

So I can say.. "Been there, done that" :P

Yeah.. because like I said.. the reverse has no syncro and is a straight cut gear.
Haven't seen an open one for a long time, but I remember something like that. It's possible what you said.. so check that out.. I don't think the selector forks bend so easily (But you ganas, so I won't make that say that it's a sure thing! :P), but for me, it's more likely something got stuck somewhere.

Just for fun.. I googled up something from howstuffworks.com just now... just for a diagram, but found something else instead..

They have a video of a honda transmission and how it works!.. should be fun to watch for those that still don't understand syncros, reverse gear, layshaft, input shaft and all that mumbo-jumbo :P

Remember.. the video.. the rest of the text are talking about generic gearboxes, but they work roughly the same.. but that's not important.. the thing is, you can now see how a real honda transmission looks like, because they have a VIDEO!! :P

If some of the zth'ers were wondering about FD and differential.. zth'ers can see where they're installed in the open gearbox.. he only describes how the gears shift, but you get a rough idea how the H pattern shifter moves your selector forks, and other stuff in your gearbox.

And for akuma, I think you can see where I mean when I mean the lever moving the idler gear has something stuck in it... it's thick, so I don't think it bends so easily.

Enjoy!.. :P
