When you are satisfied that the loco is running OK, and that this is the final assembly,
remove the pivot screws and apply a thread locking compound to the threads of the
captive nut in the top of the bolster (you can use a proprietary compound, but cyano
glue, paint or even nail varnish will do the job). Replace the pivot screws, tightening them
only so far as to put a slight preload between the bolster top and the pivot plate, whilst
retaining a reasonably free (it doesn't have to be loose) pivoting movement. Give the loco
another test run through some pointwork to make sure it's free enough.
Refit the speaker enclosure at the radiator
end of the chassis block. The pivot
components are arranged to just fit under the
speaker enclosure, if you machine away most
of the thickness of the original moulded dimple
raised over the pivot screw. If you are taking
power feed through the pivot screw, you can
make an additional channel through the
speaker
enclosure
moulding
to
take the
connecting wire.
Finally, replace the body of the locomotive. Place it on a level surface and adjust the
alignment of the cosmetic bogie frames with respect to the underside of the body.
Secure the frames with a couple of spots of glue when you are happy with them.
All being well, thats it! - the modifications are complete and you have a(nother)
sprung diesel loco.
IMPORTANT NOTE: If you need to remove the body subsequently, please DO NOT at any
stage attempt to pull the chassis from the loco by pulling on the bogies, as this may
damage the spring mountings.
