AF Steam Loco Geared DC Motor Conversion
This is a geared DC motor conversion that I have done on
several of my AF locos using various motors and gear ratios using stock Lionel
motors and gears. The worm gear is a recycled AF armature shaft turned down to
accept the drive gear and shortened to fit into the rear plate using either a
bronze bushing or a flanged ball bearing from an RC car. one of my conversions
was done to a
342 0-8-0 that will pull stumps now.
1.5
pound
drawbar
pull.
25 AF cars up a 4% grade...
(it has 4 traction tires) This reduces the current draw to less than an amp.
Speed is very scale.
NEW! I am offering this
conversion as a
Compete
kit
now
with
new
worm
gear.

or
Liontech's
TMCC with these.

The Motor used with drawings is a Lionel Part #600-8008-105 | |
Using a worm gear salvaged form an original AF armature, cut to length and turned down end to fit into bearing that you are using. I used a flanged 5/16" x1/8" ball bearing for RC cars (DuraTrax TL3440)available from most hobby shops or Tower Hobbies. Drill out the Lionel gear (Part#600-8010-117) and press on shaft. Add the shortened fiber spacer and salvaged thrust washer and you have it done. | |
The plate is 1/8" aluminum stock. Use an old AF field winding core as a template to drill the mounting holes. | |
