Gtech Air Ram Mk1 - switching itself off following cog replacement
« Reply #15 on: April 04, 2018, 06:48:09 PM »
Hi, I stripped my G tech down and replaced the cog. Started first time and the horrible noise has gone, but it’s turning itself off after a few seconds. It will switch back on but does the same thing again and again. Battery is fully charged. Don’t know if there was anorivlen before I replaced the cog because I only just bought it second hand. Any ideas? Is it likely I've trapped a wire or something when putting it back together? Or does it sound like a battery issue?

Check the brushrolls are back correctly, it sounds like it's encountering resistance, and cutting off to be safe. Remove the brushrolls and see if it runs any better. Is it fairly easy to spin by hand? There will be motor resistance, but it should turn fairly easily.

Otherwise it could be the battery, but short of the expense of buying another just to see there isn't much you can do there.

Yes the brush rollers are moving easily by hand. I’ll borrow my friend’s Gtech and try her battery. Jeeze, if it’s the battery I’ve been well and truly had off with this!

Yep, always a risk! That's why we don't like them very much, very fiddly when they go wrong, and parts are still quite expensive for them!

Good luck though, keep us posted!

Battery works fine in friend’s machine! And when I put her battery into this machine, the problem still occurs. It’s intermittent though, sometimes it works fine. Wondering if it’s a switch problem? Or something to do with the way I’ve put it back together!

If your feeling brave and bribe your friend, drop your motor into her chassis... It won't need to be screwed in, literally just unscrew both and drop the whole motor unit into her known good machine

Has anyone seen the drive cog look this worn?

don't see anyone selling these and don't see how this can work normally unless a tight fit etc.

Hi,

I have had the dreaded cog issue and replaced it with another nylon one, it ran fine for 5 mins and then the problem returned.
I had greased it and there doesn't appear to be any end float on the bearings/ roller brushes etc, the plastic ends where the bush sits are not worn and all parts move freely. I have seen replacement shafts available with a metal cog, so what's the general opinion on these?
Surely the reason for plastic is that its sacrificial, so should anything jam up then the motor/ other parts aren't damaged.
So, should I look for a fault somewhere else or just push ahead and buy the metal gear?

The ones we sell are metal. I didnt know anyone still did the nylon one for the reasons you describe.

That's odd. I just looked on your website and the photo shows a nylon gear?

Its an old photo. The ones supplied have been metal for a year or two.
