Fleischmann worn plastic cog not connecting with motor
« on: June 16, 2019, 01:01:57 PM »
Hello, I’ve set up lads train track and trains motor started whizzing and train wouldn’t move. Upon taking it apart I can see the cog connecting to the motor has worn/melted so it’s not running the wheels. I’m really struggling to find a spare. Been on the website but assuming I need the number for that very cog and I can’t see how to take it apart further, I know this is clear as mud so I’ve put some pictures on, any advice on finding that part greatly appreciated!

Edit: I have had it completely apart, I swapped the cog around hoping it would catch the small cogs that go onto the well but alas still missing each other.  No number part on the cog itself.

Oh dear, that gear is well shot!

I believe the little 0-4-0 loco isn't in production.  You might do better looking for a 2nd hand one on ebay or at a show?  Look for Fleischmann model 7000

I have many Fleischmann locos but not one of those.  If a spare gear is available, I would imagine it will be a case of pushing a metal shaft out of the chassis in order to replace the gear.

[edit]

Here's the service sheet.

Looks like you need part 56 7105  *but* you need to consider why has it worn out? Is the worm also damaged, or has the motor been running loose or without any lubrication?

Thank you, I will keep any eye out but train funds are low ha!

Hi Bill (?), please refer to my edited reply above:

Part 56 7105  can be found in some German shops, as below. In itself not expensive at all, but postage may cripple it!

You could maybe try contacting Gaugemaster or A&H models in the UK?

Ah you are a start thank you found it on Fleischmaan's site, £11 with postage, expensive for a cog but cheaper than a new train! Gaugemaster only have HO gauge, thanks again!

Yeah but GM could probably get hold of it and probably would be cheaper postage.   

Anyway, good luck but as I mentioned do try and work out WHY it is so worn, and take steps to avoid the same happening to the new part?  That much wear is very unusual and usually would indicate something like a loose motor, or something jamming up?

Thank you, I will send them an email before I order.  I would imagine it's due to lack of lubrication?  We have used it extensively and never lubricated it, to be honest I didn't know you had to!

Yes, but only very sparingly.  It needs to be a plastic compatible lubricant. I've had a bottle of Fleischmann "Special Oil" since the 70s and I use that for the motor bearings etc.,  but these days for gears I use a tiny pinhead amount of PTFE grease rather than oil.  Maybe once a year, as part of giving each loco in my fleet a service.

I have a running example of the loco illustrated in the photo - Loc 7 Maffei - complete except for the valve gear/connecting rods missing for a reasonable price (cane as part of a job lot). PM me if interested
