R.White Posted April 22, 2015 Share Posted April 22, 2015 My 6 volt North East generator has a screw in the end plate for 3rd brush adjustment (and a clamping screw) but the adjustment mechanism no longer works. It looks like some kind of rack and pinion affair but I need to get the generator off the car to get a better look. Has anyone had experience of this problem and if so can they help / advise me on a fix please. I think the serial No. is 327. Another number stamped is 6334B.

cahartley Posted April 22, 2015 Share Posted April 22, 2015 If you take the brush cover off you should be able to pry on the movable brush holder to get it moving.If you have an impact screwdriver jarring the screw with the pinion gear on it might be all that's necessary.

Ron Lawson Posted April 22, 2015 Share Posted April 22, 2015 Ray Dont go near the generator with an impact driver as it has more than likely got a pot metal end plate Link to comment Share on other sites More sharing options...
R.White Posted April 22, 2015 Author Share Posted April 22, 2015 The screw just keeps turning. It's not connecting properly with the mechanism; as though it's stripped a thread or something. With the cover off, however, I was unable to move the third brush. It's as though the brush can only be moved with the screw. It was working O.K. last year but now I seem to have broken something. I didn't really want to remove the end cover to get to the mechanism because I have no experience of North East generators and knowing my luck it won't go back together again! The generator was a rebuilt unit imported a couple of years ago and works well but I need to reduce output a bit.Ray.<script type="text/javascript" src="safari-extension://com.ebay.safari.myebaymanager-QYHMMGCMJR/4dd8d9fb/background/helpers/prefilterHelper.js"></script> Link to comment Share on other sites More sharing options...
cahartley Posted April 22, 2015 Share Posted April 22, 2015 The screw has a little gear on it which meshes with the brush holder.BTW....I said "jar" the screw......not beat the hell out of it...... Between gently prying on the brush holder and trying to turn the screw it has to move........there isn't anything else holding it....... :confused: Link to comment Share on other sites More sharing options...
R.White Posted April 22, 2015 Author Share Posted April 22, 2015 The screw just keeps turning round without moving the brush holder either way so perhaps it's a broken pinion? I tried prising the brush holder but it won't go either way despite making sure the clamp screw is loose, so what 's stopping it I don't know. Perhaps a little WD40 would free it?Ray.<script type="text/javascript" src="safari-extension://com.ebay.safari.myebaymanager-QYHMMGCMJR/4dd8d9fb/background/helpers/prefilterHelper.js"></script> Link to comment Share on other sites More sharing options...
cahartley Posted April 23, 2015 Share Posted April 23, 2015 Wow....... :mad:There isn't much HOLDING the darn thing.Like it or not, for the sake of the unit, I think the back needs to come off....... Link to comment Share on other sites More sharing options...
R.White Posted April 23, 2015 Author Share Posted April 23, 2015 Please advise me... It looks like the the back comes off as you would expect but is there anything about this unit that could cause me problems? Can the mechanism be repaired?Ray. <script type="text/javascript" src="safari-extension://com.ebay.safari.myebaymanager-QYHMMGCMJR/4dd8d9fb/background/helpers/prefilterHelper.js"></script> Link to comment Share on other sites More sharing options...
R.White Posted April 23, 2015 Author Share Posted April 23, 2015 (edited) Update: I have been able to free off the 3rd brush and slide it either way. I can now adjust the output directly.Thanks Guys.P.S. the damaged parts have been retrieved from the machine and I plan to restore it to normal.Ray.<script type="text/javascript" src="safari-extension://com.ebay.safari.myebaymanager-QYHMMGCMJR/4dd8d9fb/background/helpers/prefilterHelper.js"></script> Edited April 23, 2015 by R.White (see edit history) Link to comment Share on other sites More sharing options...
cahartley Posted April 23, 2015 Share Posted April 23, 2015 YAY........ What was damaged?Happy you got your problem sorted....... :cool: Link to comment Share on other sites More sharing options...
R.White Posted April 23, 2015 Author Share Posted April 23, 2015 The little sprocket had broken off and caused the mechanism to jam. I am scratching my head about how it was fitted on the shaft of the screw? What stops it from turning or coming off? Is it just a press fit?Also, the locking screw had a non original nut and both of them will also need to be replaced.

R.White Posted April 24, 2015 Author Share Posted April 24, 2015 It would seem that the little cog wheel that drives the adjustment 'rack' is machine pressed onto the shaft of the screw to prevent it coming off and there is a tiny fixed key (like a woodruff key) to stop it turning on the shaft. As stated, the cog has broken off the screw. The end of the rack is also damaged but still usable. There seems to be no simple way to effect a repair but a replacement end plate seems like overkill.

cahartley Posted April 24, 2015 Share Posted April 24, 2015 How about drizzling some wicking Permatex Threadlocker between the pinion and screw?That stuff is amazing! Link to comment Share on other sites More sharing options...
R.White Posted April 24, 2015 Author Share Posted April 24, 2015 GOOD IDEA. I have some and thought about doing it when I was tinkering with it this afternoon but the cog hasn't just come off, it's cracked and splayed open. I squeezed it back into shape and re positioned the parts but that's about as far as I got before getting distracted looking for my 'Lumiweld'. I thought a safer repair would be with a gas pencil torch and some low temperature aluminium welding that also does pot metal... but do you think I can find the stuff?. I sometimes think there are evil spirits living in the darker recesses of my garage which conspire to make my life more difficult than it needs to be. I do, however, realise that I am very fortunate to be living here and now. Another day tomorrow.Ray.<script type="text/javascript" src="safari-extension://com.ebay.safari.myebaymanager-QYHMMGCMJR/4dd8d9fb/background/helpers/prefilterHelper.js"></script> Link to comment Share on other sites More sharing options...

R.White Posted May 5, 2015 Author Share Posted May 5, 2015 Job Done! It has taken a while but I made up a clamp and screw in Brass and also made a 15mm 11 teeth spur gear which I have fixed on the end of the adjuster screw - it meshes with the third brush holder now. Tomorrow I will reunite the generator with the car and then adjust the output for "summer" charge.Then it's Vroom Vroom Vroom !!. About time I gave the Villagers something to talk about!Ray.<script type="text/javascript" src="safari-extension://com.ebay.safari.myebaymanager-QYHMMGCMJR/66cc1b69/background/helpers/prefilterHelper.js"></script> Link to comment Share on other sites More sharing options...
