the support brackets for the crosshead and front brake hangers. Will
provide pictures further on. After I completed that portion I thought things
would finally be moving along. I was anxious to start on the valve
gear, so the next step was to mount the crosshead slide on the newly
made support bracket. Then, you know the saying.. take one step forward and
As I attempted to
install the crosshead slides (which connect to the rear cylinder head
and the support bracket), I found out that the front connecting rods
stuck out 1/8" into the path of the crosshead slide. What a depressing
moment. I had visions of ripping everything apart and starting from
scratch. After a couple days of deep thought I finally came up with a
quick and relatively easy solution. Basically, what I did was modify
the connecting rods, pins and the method I connect them to the drivers.
It took a bit of work (like pressing the axles and pins off the drivers,
re-machining the pins, drivers and connecting rods, etc.) After it was
all done, it all worked fine and looked great.
After that, I
started to complete the job of installing the crosshead slide bars.
Problem #2... I couldn't get them to slide without binding when
attached to the rear cylinder head cover. Shims didn't help either. I
realized that the method I used for connecting the piston rod to the
piston and crosshead had contributed to this problem. Basically, the
movement of the rod was not parallel to the slide. Being that the slide
is an alligator type, this made it more critical than a 2 bar slide.
So, now I am remaking the piston rods, pistons and re-machining the
crossheads. I am using a taper on the crosshead end, will press the rod
into the crosshead and use a taper pin to secure. I previously threaded
the rod into the crosshead and piston. Improper alignment of the
threading process caused most of the problems. On the piston side, I am
using a taper and will press the rod onto the piston. I am using a
5/16" nut to secure the rod to the piston....
Finally got the
kinks out of the crosshead assemblies. They look nice and work real
