Instructions for Retrofitting
LIQUID SMOKE GENERATOR KIT (8141-55K)
In Lionel Pill-Type Smoke Units

I.  	Remove the metal cover (It will not be used), and thoroughly clean out the smoke pot, the vertical air spout, the housing cylinder and the smoke piston.  (It may be necessary to use a thin wire to unclog the vertical air spout.  A paper clip works fine.)

II.	Slide the white fiberglass wick #8141-56 over the resistor #8141-55.

III.	Put the shrink tube #2029-15 over one lead and heat-shrink close to the resistor body.

IV.  	Carefully bend both leads 90° close to the resistor body.  Insert the leads through the holes in the black cap #2029-16.  The insulated lead goes in the larger hole.

V.  	Put a new fiberglass liner #671-212 in the smoke pot and seat the cap and heater assembly in the pot.  The resistor must not touch the air spout.  Early 671 and 675 pots are smaller.  In this case, the cap fits outside the smoke housing and you will need to clip the internal "fins" to allow proper seating of the cap.

VI.  	Next, extend the insulated lead (if you need to).  You may wish to use another piece of larger shrink tubing to insulate this connection.  This lead should be connected to a center rail pick-up wire (E-unit or head light wire, etc). 

VII.  	Now connect the ground lead to a convenient place.  You can solder this lead to the smoke housing itself, or you could solder a lug to it and attach it the locomotive frame with a nearby screw (Example-smoke unit support screw).

VIII.  Place the felt smoke gasket #671-181 or alternate#726-57 on the top of the smoke unit before inserting motor and smoke unit assembly into cab.  This gasket prevents smoke fluid leakage and further insulates the hot lead from the locomotive body.  

IX.  	Finally-install the 2026-44 spring between the piston and the cylinder of the smoke unit.  The spring serves two purposes.  First-it quiets the operation by preventing a clanging noise caused by the falling piston and second, it provides a more positive operation of the piston by forcing it to the return position.
