Down_Under Posted May 25, 2018 Share Posted May 25, 2018 Hello All, A little advice sought on gear puller/wheel pullers. I have a GW gear/wheel puller, for the most part this works quite well, but a little fiddly sometimes to use and not so great on plastic gears. I have come a cross a couple of these gear/worm pullers on ebay: Worm Puller Gear Puller Has any one any experience with these or any other recommendations? The worm puller looks like it would also work with wheels - especially those that a interference fit on the rim. Looking for something to remove worms, gears and wheels. Cheers, James Link to post Share on other sites More sharing options...
RAF96 Posted May 25, 2018 Share Posted May 25, 2018 I once modified a push-bike chain link splitter for use as a gear puller, but its gone AWOL and I can’t post a picture of it. I also had a smaller but similar item used for taking links out of metal watch straps, but I guess that's in the same box - must have gone overboard when we moved overseas.

RMweb Gold Enterprisingwestern Posted May 25, 2018 RMweb Gold Share Posted May 25, 2018 In what way are you struggling with the GW puller? I use mine exclusively for pulling wheels and gears off axles when doing EM conversions, and have no problems. Mike. Link to post Share on other sites More sharing options...
bécasse Posted May 25, 2018 Share Posted May 25, 2018 Assuming that you have already removed the wheels and thus just have the axle with the gear on it, place a washer which is a little larger than the gear wheel behind the gear and pull that. I actually have some washers in which I have filed a ⅛" slot so that they will slide over an axle behind plastic centred wheels (Alan Gibson Workshop ones, for example) - it is much safer using the GW models wheel/gear puller on the washer than on the wheels themselves.

I was having issues with the sharp edges of the 'hooks' damaging small plastic pinion gears when pulling them from RTR axles to put onto P4 axles. Secondly some of the AG wheels the hooks seemed to engage with more of the rim that I would like rather than the plastic center which has led to a couple of wonky wheels. Maybe it was my fat fingers - im sure some operator error is to blame. J But I think I might use some washers to help spread the load Link to post Share on other sites More sharing options...

Down_Under Posted June 5, 2018 Author Share Posted June 5, 2018 Th aka for all the replies - any suggestions on how to get a high level worm of a bung mashima motor? Or is this more a nice email to high level for a spare worm? J Link to post Share on other sites More sharing options...
bécasse Posted June 24, 2018 Share Posted June 24, 2018 Th aka for all the replies - any suggestions on how to get a high level worm of a bung mashima motor? Or is this more a nice email to high level for a spare worm? J Sorry, I have only just seen this one. I assume that the worm was fixed to the motor shaft using 600-series Loctite, in which case heat will break the Loctite bond, how much heat depending on which of the 600-series was used. I still use 601 and boiling water is sufficient - almost fill a plastic cup with boiling water and just dip the worm in. I should add that I got the idea when I saw someone apparently dipping a motor into a plastic cup of tea at an exhibition. Curious, I asked what he was doing and it was explained to me - it works, too, I have successfully used the technique myself on several occasions. 1 Link to post Share on other sites More sharing options...
Nearholmer Posted June 24, 2018 Share Posted June 24, 2018 Load spreaders are very important. I know ‘cos I damaged a cast iron wheel on an old 0 gauge loco because I was in too much of a hurry to be bothered to make a special one for the job, which would have taken all of ten minutes. It would be good if someone learned from my mistakes, because I seldom do! Link to post Share on other sites More sharing options...

Cheers, James I use the first one quite often, it's quite sloppy but works. Link to post Share on other sites More sharing options...
