I've aways liked the little Jouef locos.
There's something really pleasing about them proportionally even if they are technically over scale for 009, and even more so for the HOe market! Performance wise though they do leave a little to be desired. Thankfully Tramfabriek make a very simple motor replacement kit, so a on a weekend where modelling time was short the conversion took place.
This isn't a step by step guide by any means (There's already a comprehensive 'how to' on the Tramfabriek website) but more just some observations as I went through the processes.
Disassembly is fairly straight forward, and reveals the fairly chunky original motor.
The trickiest part of the process I found was removing the screws that how the motor brushes in place. A combination of very little surface for a pair of pliers to grip and the screws probably never having been taken out out since being put in back at the factory a good fifty years ago!
And after removing the motor itself, to my surprise it fell apart perfectly into its component pieces!
I did wonder if this is the cause of the intermittent running, but the new motor and housing were all ready for installation. The metal pieces have been kept in the spares box as a possible source of ballast for wagons, they're quite weighty.
For completist sake, a photo of the chassis with the motor out. It's a somewhat unusual transmission of power from what would now be considered the norm.
And then, a disaster! The worm gear from the original motor split whilst being removed. Looking closely though showed the break occurred due to an air bubble inside the plastic piece itself. Mercifully it was a very clean break and if anything it actually helped with the stage of glueing the gear onto the new motor.
The new motor installed.
And finally a quick pose as the loco spent a good half hour going round the in-progress Welsh narrow gauge layout to have a run in. It's already a vast improvement, and with some careful driving can really crawl at a much more realistic speed. There is still an occasional stutter or stop (Mainly due to the insulfrog points) but it's far less frequent than before.
Really, I think I might have to disassemble it again and give the wheel contacts a good clean, something I really should have done in the first place.
A project for another day, along with eventually constructing a new cab and matching tender.
