Hi Bill --
You just jogged my little brain! I have two Ajin F unit chassis that I can
use to redo my GP-7! I had thoughts of changing over to Sagami motor and
AM trucks, but there is a bit of engineering involved and I haven’t had the
time or interest to pursue it. I used the original truck side frames as a
starting point for my AM replacements that I had cast many years ago (I sold
a bunch of them at less than $8 per set, ready to glue in place...), knowing
full well that a repower was the long term situation from the moment the
engine came from Sunset.
Thanks for the inspiration!
See you next week!

The new issue of Classic Trains has a killer article on GP7 & GP9.
Just for a goof this afternoon I got out my torpedo top GP7 for the first
time in MANY years to eyeball it. I have never run it. I had visions of
happily machining out some new floor blank on my milling machine or chomping
a American Models drive to make it all fit on its way to a new drive. Some
years ago – possibly at Pontiac RRM had a table full of various Overland
diesel components. I thought I was done buying until I saw THAT. I went well
above and beyond the BROKE point.
I bought some gear tower wheel assemblies that might have been in the
original F unit drives. In 5 minutes time I saw they COULD be a ***direct
swap out*** for the Sunset parts. At 10:30 PM I drilled out the original
Sunset side frames for slightly larger axle ends. This idea has real
possibilities. I did not check for free rolling – YET. If I had known it
could be this easy I would have done it a long time ago. Complex is not
always the way to go.
Thank You,
Bill Lane
