When I bought this Silverliner for my book project, it ran terrible- as most long axle Kumatas do.
--Cracked u-joint cups (typical Kumata)
--Wobbly wormshafts (typical Kumata)
end result- electric razor on wheels (almost).
Changes:
New plastic main drive gear (quieter).
Added flywheels.
Replaced u-joint.
added weight for better electrical pickup.
Added TCS Z-2 decoder.
Added support for the motor (motor sits on decoder!)
blacked everything so inside in unnoticeable.
Added windows.
Added black numberboards and correct numbers (side and noses).
Added proper PRR Keystone.
Added excellent fiber optic headlights (stock is unlit).
Made light board with TCS micro-plug socket for easier service.
Added heatshield for motor (to protect wires for light board).
Z scale couplers (though I also have MT 1025, and a drawbar) - stock had nothing.
Here are some photos in a couple of posts.
I didn't feel like editing them. (sorry).
Made a 2.3 minute movie to show how quiet this thing is and how it creeps.
Enjoy.
