Motor size

[Meter rat]

Does anyone know the size of the motor in the Tamiya recoil on the tiger? Mine seems to have failed. I am trying to avoid paying for a complete replacement.

its a weird size that I have never found in the usual outlets. From memory, you can get the motor (more or less) on its own by buying the replacement part for the Leopard 2? There is no mechanism with that version, just the motor and some cables that you will have to swap over when you fit it to your Tiger unit.

Edit, doesn't even look like you need to swap the cables (must confess its been a long time since I had to do it):

Hello, it is a small "Igarashi" brand engine, what is your concern? are you sure there is an electrical problem? Personally, I had problems with the plastic worm (crown drive), which turned on its axis ?
have you tried with direct 5 volts on the motor terminals, by unplugging the Tamiya electronics

Pretty sure its a Mabuchi, at least that is the branding on the motor I have here. It says FF-130SH-14230, and 9V on it.

Looking around Ebay, there are a lot of similar motors - but without the spec sheets to compare, it is a minefield. At best you may end up with a motor that runs too quickly, at worst you might get one that draws too much current or can't produce enough torque (and thereby stalls).
The recoil circuit on a Tamiya MFU is the weakest part, there is no over-current / stall protection and it fails very easily. Fitting the wrong motor is a risky propersition, where as just ordering that Tamiya part number I linked you will get the correct motor. If you don't mind waiting a while, Time Tunnel Models will be able to order it in from Tamiya for you if you drop them an email request with the P/N.

I am not using the Tamiya MFU. Rather, it is connected to a Heng Long 6.0 MFU. The motor has stalled a couple of times. Your explanation, is probably why it has failed, as it was very warm and a small amount of smoke.

Jofaur86. The motor has failed in a puff of smoke. Tested on a separate 6v supply, with no load. Not too fused about recoil if I cannot repair it. As and when I can be bothered, or can afford it I may change to a 7.1 MFU.

Thanks for the help. I have emailed Time Tunnel Models.

If you have let the magic smoke out of the motor, then you should probably make sure that the gun is moving freely. Might just have been a bad motor, but Mabuchi always used to be considered a high end aftermarket replacement brand by the model train community back in the day.

Contacted Mabuchi, if they supply bottles magic smoke as a service item. It is not available to the public, as it is a none service item.
The problem was caused by the recoil getting jammed, do to continuous running when testing , as the micro switch was faulty and not cutting the power. All worked for a while, but the damage had been done.

been a while but are they not the same as these?

That looks an FA130 motor. The FF and FK models have the terminals on the end of the housing rather than on the top.
