is up. The frame should slide over the bushing with-
out too much pressure. Don’t force it or you risk 
bending the frame. Once this has been accom-
plished, do the same with the front axle. Your as-
sembly should now look like photo 3. 

Screw the front and rear frame spacers between 
the frames with M2 x 4 screws (3), as per the draw-
ing. Then screw the middle frame spacer (11) into 
position behind the rear drivers with M2 x 4 screws. 
The chassis should roll smoothly as this point. 

Screw the end beams (6) to the frame spacers 
at both ends, using M2 x 10 screws (8) with D2.2 
washers (7). Screw the deck plate (10) to the 
frames with four M2 x 3 screws (72).

1-3.

 Screw the lower boiler mounting plate (12) to 

the frames with four M2 x 4 screws (3), sliding the 

plate  between  the  frames  with  the  flanges  down

-

ward, as per the drawing. Make sure the four holes 
on top are toward the rear of the engine. 

Screw the two rear boiler saddle pieces (13) to the 
rear of the edge of the upper boiler mounting plate 
(14) with M2 x 3 screws (72), paying close attention 

to the drawing. Then screw the front boiler saddle 
pieces (16) to the upper boiler mounting plate with 
M2 x 3 screws (72). The assembly should look like 
photo 4.

1-4.

 Screw the assembly to the frames with four M2 

x 8 screws (15). You may have to loosen the rear 

boiler saddle pieces so that the notches in them fit 

over the frames and the holes in the upper boiler 
mounting plate align properly with those below.
At this point, your chassis should look like the draw-
ing on sheet 2.

3-1.

 Find the cylinders (43), the gaskets (45) and 

the valve assembly (47). Screw the cylinders to 
the upper boiler mounting plate with three M2 x 6 
screws (46) each.

3-2.

 Slip the side rods (34) over the crankpins on 

the wheels. With a small pair of needle-nose pliers, 
carefully snap an e-clip (37) into the groove on each 
of the front drivers’ crankpins to retain the side rod.

Now, working on one side at a time, slip the spacer 
(35) over the rear crankpin, followed by the main 
rod assembly (36). When installing the main rod as-
sembly, note that the crosshead (the small, black 
piece on the end) has a small, threaded hole on 
one side with a set screw installed. This hole must 
be in the “down” position when the rod is installed. 
Retain the rod on the crankpin with an e-clip as you 
did the side rods. 

3-3.

 The main rods can now be connected to the 

piston rods in the cylinders (43). Pull the piston rods 
out a little (they may be stiff) and examine them. 
You will see a dimple machined into the side of the
