WM #62 F7A from Highliners Kit- Genesis Mechanism
Overview
Mechanism Overview
The mechanism comes with a frame, trucks, clips and a cab. The fuel tank
and battery box detail is not very good compared to some others I've seen, but
it is a good runner and a decent place to start.
One of the most important things the mechanism comes with are the clips. I
haven't looked at other mechanisms on the market so I am not sure if they
provide the same or similar clips.
As you can see in the photo, the clips fit the inside of the Highliners shell
via round "windows" that fit into the window cutouts from the inside.
These do not protrude through to the outside so you will still want to use the
Highliners window "glass".
Don't lose or break these clips!
Mechanism Disassembly
One of the first things you'll want to do is disassemble the mechanism. I
failed to do this at first as I didn't realize how messy drilling the frame was
going to be. Halfway through drilling the locator holes for the details, I
disassembled the mechanism completely. Dissassembly will make painting
easier as well.
Since you will want to detail the sideframes (and in my case, replace the
wheelsets), start by flipping the mechanism over and prying off the cover on
the bottom of the gearbox. You will not be able to remove the sideframes until
you pop this cover. There are four tabs, unclip (with a micro
screwdriver) both clips on one side, and then unclip the other side.
 
Pull the sideframes out, and if you are replacing the wheels, remove the wheels
as well.
Unclip the wires from the sideframe by pulling the clip out with needle-nosed
plyers.
Once the sideframes are removed, clip the cover back over the gearbox.
Repeat with the other truck.
Flip the mechanism back over and pop the worm covers off. These come off
fairly easily by prying one side. They clip on the front of the
gearbox. Remove the worm and shaft by lifting up on the black plastic
coupler behind the worm. Do not touch the worm with anything other than
your fingers, lest you damage it.
Remove the truck from the frame and pull the worm and shaft out of the
motor. Reassemble the truck to keep everything clean
Once you have removed the trucks, it is time to remove the motor from the
frame. If you want, you may unclip the wires that lead to the
trucks, but that is not necessary. Simply unscrew the screws from
the bottom of the frame and lift the motor out of the chassis.
Here's what the frame will look like once everything is removed (note: this
photo was taken later, so the details are on the fuel tank already)
