ETA 2783 Canon Pinion adjustment

[chrisdt]

Can anyone tell me if there is any special procedure for tightening or loosening the canon pinion on an ETA 2783 please? At present it is very tight. Yes I could ream it out a little but if I do it too much how do I tighten it again as it doesnt appear to have the usual crimp marks? In fact its not crushable.

Many thanks

Hi there try a good lubrication D5 or jisma that may loosen it where it fits into the driving wheel

Do not ream it out. The reason that there are no crimp marks is because the friction coupling in this set up is not via a crimp that grips the center wheel pinion, but via those two parallel spokes in the wheel that is attached to the bottom of the cannon pinion which run in a groove in the cannon pinion, gripping it to provide the friction coupling.

A touch of D5 or HP1300 in the coupling groove should help. It's also worth making sure that it is really clean first as an accumulation of old dried oil in the groove could be gluing things up.

Thanks Marc...Never come across this set up before....That should sort it out
