Repower Athearn H0 CF-7

[faraway]

I did find by chance that the Kato GP35 motor (part number 956010, on stock) fits with it mounts and screws perfect into the Athearn CF7. The quality of Kato motors are well known and that is the most easy mechanical repowering possible. You may also use the Kato PBC to keep the motor mounts aligned or do some rework to mount the Athearn PBC on top of the Kato motor. The Athearn bulbs stress the Kato PBC. You should significantly dim them via DCC decoder settings (in my case down to 80 from 255).
Might be that motor fits in some more Athearn RTR diesel engines. e.g. GP38 etc.

ps. The Kato GP35 trucks do not fit. The bolsters are far to low.
