A lot of parts, a lot of work, but there is hope!
Märklin 3102
"Borsig Mallet"
One of my favorite locos.
A customer project:
This loco was not running anymore, most of the gears completely
worn out.
After the loco was disassembled, the whole damage became visible.
A lot of parts, a lot of work, but there is hope!
The rear frame with only the drive wheels left in.
Behind the wheels starts the disaster. All gears are badly worn out.
All the gears, intermediate gears and the pins need to be replaced.
Frame and gears after a deep cleaning.
The brush holder plate shows copper particles from the commutator.
Commutator and gear from the 5 pole motor worn on both sides.
Tender after cleaning & rewiring, reconnected the wheel power pickup.
