As Galen wrote before, i too see no need to place the motor in the tender. If the motor is in the tender you need to use a long drive shaft with two universal joints and with a telescoping member in the middle.
On the photo it seems to me there is a brass bushing over the Motor shaft. And it's outside diameter is equal as the diameter of the gearbox input shaft.
One of my sugestion is to open the gearboxand remove the worm.
Then remove the bushing of the motor shaft, replace it with a longer one, long enough to reach into the front bearing of the gearbox if the motor is mounted directly straight on to the gearbox. Then mount the worm to this elongated motor shaft. The original bearings of the gearbox will fix the tiny motor. The only other thing to do, is to mount an torque support to prevent the motor casing to revolve. This torque support should be a little bit flexible as there is shaft with four bearings.
Then the motor will be within the boiler backhead.
Another sugestion is to built an own gearbox. But this is not everybodys case. I have done so on my L1.
