The ratchet plate in the photo looks correctly orientated to me.

Indeed. Nice sharp points too, not rounded off.

Thanks all for reply.. The nudge in the detent plunger was worn and did not secure the groove. I made a new one.
Theoretically you should say that the srping load presses the chisel in the dents, but between 3 and 4 (?) there is a larger plain surface, maybe it can turn at this point.

It does not explain however, why upshifting is no problem, and downshifting is.

I have gotten a new tip from the German enfield forum.. New testride today but boy.. am i nervous? These stupid things really can get to me..

[jawa-enfield]

Report; Rotated the lid on the mainhaft 180 degrees so that the recess is on the left side (Tip form German bloke) but.. this only gives room for UPshifting? And not for downshifting?

However, twisted the 'repaired' detend plunger thighter (ordered a new one, it is not secure anymore) and for 4 to 3 goes!!

But, from 3 to 2 is still impossible..
It does not get enough movement.

So..
Maybe rework nr17 so that more movement is possible? (But what is then the effect on the other gears?)

Also, when removed the detent plunger, i can move part nr 33 a little to the left/right with a screwdriver.. something has some play.. Could that be a/the problem?

[jawa-enfield]

Some additioonal info; The ratched has a little play on the square spindle (actuator shaft?)
Further; with the detent plunger removed you can see that the shifting bell does not move enough down.
Despite all manuals, rotating the adjustor plate has not a single effect.

As if the ratched is 1 tooth too late? Despite the mechanismn is pushed against thge stops...

I hope this is going better for you? There are, of course, a lot of videos on utube. Any good?

I wonder if all your parts are ok. Many years ago I had massive problems with ALL-NEW parts on my car's windscreen wipers.
They went way past the edges of the screen. Lots of telephone conversations with the very helpful suppliers, who EVENTUALLY discovered there were two extremely similar, but different parts in their parts box. I don't know if this could be a problem here?

Having adjusted the change on my own Bullet gearbox, I was surprised how LITTLE adjustment was needed to have a good effect. It's mentioned at one point above, if adjusting would solve one pair of gears, but create problems between others. My experience of this is certainly NOT ALWAYS...

Good luck, Chris

It has just struck me, looking at your pictures, that you may have the alloy cap over the mainshaft bearing the wrong way around - they usually have a bit by one of the bolts ground away a bit, to allow the required movement of the gear change mechanism for down shifting. It may just be a matter of slewing the cap around by half a turn, to allow a bit more movement.

Hi, what direction are you adjusting the backplate? Vince

[jawa-enfield]

Dear Folks
The alloy cap was indeed 180 degrees wrong, which can possibly give trouble in upshifting. This was not the case but mounted it the correct way anyway. (because of previous problems with the gearbox, such as hole for the bronze bush was not in line) an expert in these gearboxes offered to mount it together and adjust it. . i assumed/didn't notice the alloy cap)

I am really 'stuck in mind' that is has worked with these parts.. or not? And it should do so again?

From 3 to 2 was not possible and turning the mechanism (manuals say clockwise, but it seems - if it should work- the other way because of the movement for UPshifting gets bigger this way) has really not a mm. influence on the distance the shifting bell moves... so maybe smething here is at stake but.. really complicated is the system not?

I ordered new parts for the mechanism and new detent plunger and took a file and worked on the stop plate to get more movement downshifting.

Yes this also influences the other downshifts which are okay now but i guess the detent plunger has to solve that.

Filed a few mm's away and did a test drive, first run with the nbew rebuilt engine over 10 km's
Detent plunger is a little thight but shifting went okay!

I will look what the new parts will do when they arrive.

Now time for the next problems (oil leakage, and electrea-blues will come along with the stdty. rectifier/regulator?)


Through the hole of the plunger you can check how far the bell moves and ofcourse you can feel at the rear wheel if it takes or not.

if the ratchet plungers are both pointing in the same direction the box will only shift in one direction. The downshift plunger may not be fully deployed

Huh? What's a downshift plunger?

I can only think of one object that in any way resembles a plunger in an albion gearbox. There is an eccentric ratchet mechanism for rotating the gears into position and there is a plunger detent that locates into notches in a very roughly made gear position arc to hold them there. A lack of pressure on that detent plunger might stop a gear holding in the correct position but it shouldn't prevent it shifting.

The picture 6 posts up from this one shows the selector ratchet mechanism.
