Does anyone know of a direct replacement motor for my slightly worn out cuckoo chassis? I would also like the worm gear as well.
Many thanks
Eddie
There is no direct replacement for the Minitrix type motor used in the Ibertren 0-4-0, other than a second hand one from another chassis as these motors are no longer made.
What is the problem with the motor? It is usually the chassis that ware out first on the Ibertren, in particular the plastic gears between the two axels. The motors tend to out live the chasssis.
If the motor is making a squealing noise and is stalling as the speed increases it has dry bearings.
When working with these chassis it is worth remembering that they were a very cheaply made low quality product and were at one time under
I'd have thought that Branchlines may be able to sell you something from Japan (Mashima and the like) that will fit into the hole vacated by the Ibertren motor. It should be possible to get the worm off and swap it onto the new motor. GW models make a very nice worm puller, though if the old motor is knackered then that makes getting the worm off easier as you can try heating the worm (assuming it is brass) and cooling the motor shaft and / or using 2 pairs of pliers to leaver the worm off. You will probably need to make some sort of mouting bracket for the motor, but that could be as simple as a bit of brass sheet with holes drilled in to take the motor mounting screws which is then fixed to one or other ends of the Ibertren motor mounting cradle, or L shaped with the base sitting on the top of the chassis block. If the holes are slotted vertically then you will be able to get some adjustment on the worm mesh.
Yes, you can replace the motor in a cuckoo chassis.
A vice and good pliers being the main tools and someone holding it while the other taps it out.
I am certain Ian Turner did an article on it in the 009 News at some time and I know Roger Christian has replaced motors, because I have helped him. Always better to have an extra pair of hands.
I am certain the replacement motors came via Branchlines.

I agree with both the above posting that there are motors that can be used in the Ibertren chassis, but they all require some modification to the chassis and/or a new motor bracket and they will all need the original worm gear to be reused.
However Eddie was specifically asking for a direct replacement including the worm gear and none of the replacement motors that have been mentioned or that I have seen can provide that.
