The LGB Lehmann Porter's drive specifications are very similar
to No 1 in 1:20.3.
 |
Drivers are 1.23 inches in diameter. The wheelbase is 3 inches.
Cylinder diameter is 0.67 inches. Cylinder length is 1.21 inches.
Valve chamber width is 0.77 inches. The piston even slants upward to the front as
does the prototype. Best yet, one was gathering dust in my basement. |
Bashing the Drive Train
The LGB Porter drive train is held to the top part of the engine
by two screws located under the pistons and screws holding the cab to the
deck. Pull three connectors off their pins and you are down to the
drive. I removed the deck plate as the cab is much lower on No 1.

With the deck for thee cab removed, the drive block has the following
look from the side. Valve gear and rods have been removed for
painting.

This view is from the top of the drive block. The two screws in
front of and in back of the drivers hold down a plate providing access
to the motor.

This view is of the bottom of the drive block. The four screws
allow access to the drivers. The center track pickups and the
wipers to the drivers have been removed as this engine is being
converted to battery power.

The plate covering the motor in the middle photo rides too high for the
boiler to be placed above. There is some clearance between the cover and
motor. But the cover contains threeplastic supports that stabilize the
motor from the top.
