Now, very slowly and carefully lift the wheel set upward. Keep a close eye out for
the driver springs as they sometimes stick to the bushings and lift out. If you drop
one, you'll need some really good eyes or a magnet to find them. If they should
lift out with the wheel set, carefully set them back into cavities from which they
came.
Drop the replacement wheel set into the chassis. Make sure the bushings are in the
correct orientation. The small rectangular tabs on the front and rear must be
upward (with the engine upside down) toward the chassis bottom cover.
Reinstall the gearbox cover with 2 screws...and then reinstall the chassis bottom
cover with 5 screws, gently press the plastic molded brake shoe detail back into
place, and install the rear drive rod screws. See, you've done it.
Lubrication
Using light machine
or household oil,
apply a very small
amount to all drive
rods, linkages, axles,
and other moving
parts as shown.
Your gearbox is properly
greased at the factory and probably never needs service however, if you run
excessive hours pulling heavy loads, it's a good idea to remove the 2 screws from
the gearbox cover and re-grease using MTH gear grease or equivalent.
