If you're willing to live with it, however, there is probably a "dodge" - before winding on, turn the speed dial a little (anticlockwise), that will cause the pins to drop into place. - IF it's caused by slop in the bearing!

In my effort to unscrew the speed dial I must have done this. Double winding problem now appears rarely. Also Z speeds most of the times works ok and winding seems smoother than before.

Did this solve the problem or is it temporary and it would be better if I disassembled it?

Also do I have to lubricate the tooth wheels before I put the crate back and if yes do I use oil, grease or something else? I've read that dry graphite mixed with grease is the best lubricant, but it's not easy for me to find graphite.

Still sounds like a bit of a CLA would help things, although you don't really need to take it apart to do that. The gears you refer to will be the ones under the shutter curtain drum, yes? Ideally a thin grease, not oil. Oil will only run off them. Personally I use a thin silicone grease but whatever you use don't use anything too heavy. Lubricate the roller pivots (top and bottom if you can) with oil but don't overdo it, they need very little. General rule is oil for bearings and grease for gears and always use the least possible. Excess oil just runs out to somewhere it doesn't belong.

WD40 may help, you'll have some trouble getting it in the right place though. You'll have to get some onto the shaft and leave the camera upside down so it runs into the right place.

First of all, which shaft do you mean? Under the speed dial I can only see the shutter curtain drum...
Secondly, why not to put some WD-40 in the hole where the tiny screw was on the speed dial?

The gears you refer to will be the ones under the shutter curtain drum, yes?

I refer to all the gears that I can see so far, which are the ones you mentioned plus four more which are under the winding knob.


Could you also tell me whether it matters if I pull up (as if I am going to change the speed) the speed dial while I try to unscrew it or not?

The shaft I meant was the one the shutter speed dial is on. From reading your post, however, I think we are not talking of the same thing. What stage have you got to and exactly which part are you referring to that you cannot remove? Have you taken off the speed dial and removed the top cover?

As for the gears, yes, they all need a light greasing.

Well, I cannot take off the speed dial, so the top cover is still there. I am trying to unscrew it anticlockwise while I hold the shutter curtain drum, but no matter how much force I use, it doesn't move...

Ok, I misunderstood what you meant by being able to see the curtain drum under the dial. You are doing the right thing so far. Try the WD40 in the screw-hole and leave it a while. The dial really does unscrew once that grub-screw is loose (or out). Someone must have tightened it REALLY tight! I'd still try some heat after you've let the WD40 soak in.

Don't pull the knob upwards when you are trying to undo it, doing that could break the limit pin that stops it turning full-circle. Having said that, you might still break the selector pin if you use too much force...persevere with WD40 and heat. I know how you must feel, it's very frustrating!

I'm quite patient generally, I think I can stand it. I hope you can stand me too...

WD-40 is flamable, so I don't know if heat is a good idea. Do you know in what kind of stores I can find a pencil-flame blowtorch in case I need it?

Ha ha, I can stand it, I've been there too!

I don't know where you are but in the UK I'd try an electronics store or a hobby/craft/modelling kind of store. You could try a hardware type of place too.

WD40 is flammable, but most of it evaporates after a while, leaving (mainly) oil. Heating the centre of the dial for a few seconds isn't likely to get it hot enough but obviously I'd be careful!
