Norton commando shifting

So on my 69 commando i just got done putting a layshaft bearing in her. got it all back together and it shifts through all the gears but the shift pattern is completely reversed 1 down 4 up what did i do wrong it feels awkward shifting like this on my norton.

If you haven't reversed the gearshift lever, you must have reversed the camplate, which is hard to do unless you seperated the plate from it's shaft and installed it backwards. Or, you were abducted by aliens and................

"but the shift pattern is completely reversed 1 down 4 up what did i do wrong"

Some one put a strange five speed gear cluster in your box while you were not looking or "you have just crossed over into the Twilight Zone".

1. If you flip the stock cam plate over (top to bottom)
2. orient the knuckle line with the top stud in 1st (instead of 4th)
results:
A. reverse shifting pattern as OP described
however :!:
B. neutral detent is now between 3rd and 4th

"1 down 4 up"
OOPS missed it 1 up 3 down normal

1 down and 4 up could happen if you have a Quaife 5-speed. They were available with either camplate, the standard pattern or a reversed pattern.

Maybe it's a Triton?

I like these replies they're pretty funny. so can the shift forks line up i the cam plate if i had it 180 off and still shift? like it is doing? or could this be in the shifter cam the way it is installed thanks for the help guts. and it is a 4 speed.

It's worth taking a good look at this oldbritts' webpage. Fred's tutorials are awesome.

How did it shift before you put in the new bearing....the same? There is a camplate out there with reverse pattern, so do you know for sure if what you have was modified or was working normally before you worked on it?

Re: Norton commando shifting puzzle

Regular AMC gearbox 4 speed:
with the cam plate exactically 180 degrees out...4th gear cam detent exactically UP, knuckle lined up with top stud, will now be in 1st gear.
the 1234/4321 action will be reversed,
The problem arises that the shifting increments of the ratchet plate is the only thing that will put it in approximately the next gear and the cam detents are never near the detent plunger at all. There will be no positive retention other than the 2,3 & 4 gear dogs holding the gears in position. They have a retention angle in the dog profile.
1st gear dogs are not reverse angle cut so it will be easier to slide out of engagement.
