I have a tyco engine and have lost the spring that holds the brush to the commutator. Where can I buy springs and brushes for this engine. The engine was purchased in 1976 before children. Now grand children want to play.

Tyco had more than 1 kind of motor.
Diesels had Power Torque motors or MU-2 motors. Power Torque was a pancake motor driving the axles through spur gears and MU-2 was an open frame motor that drove the axles through worm gears.
For the MU-2, Bowser appears to have them:

I have no part information about the Power Torque, but those motors appear to have small coil springs. There are members around here who tinker with the PT motor and might have a source that they use.
The steam engines had an open frame motor with a worm attached to the shaft. That motor is called a PM-1. I can't tell for sure, but in the parts diagrams, the PM-1 and MU-2 brush springs appear to be the same.
Brush springs for the PM-1 appear to have been made from .020" phosphor bronze wire. Clover House http://cloverhouse.com/Store/ sells phosphor bronze wire and it may be possible, though painstaking, to make your own.

Things work a lot better with a photo of the motor type. No guessing then.

The MU-2 motor doesn't use springs, it uses tension arms. The flat PT motor will use the old Aurora slot car brushes and short springs from aurora/AFX. Get the flat round brushes Aurora slot cars used, and the afx slot car springs, and you're good to go.

There's the springs. They work, I've used them on Tyco engines, $1 a pair. Easy peasy

Seller still selling these, orginal carbon-type brushes, these I've bought to replace Tyco PT motor brushes. use the small springs for AF/X with them and you're good to go.

If anyone still needs springs, try your local locksmith.
I dropped in on Prices Lock & Safe in Victoria, and they were more than happy to give me
a pile of tumbler springs, once I told the guy what they were for.
