MTH Smoke Unit replacement for a K-Line PRR World's Fair Edition engine and Tender K3380-3738G - Semi-scale Streamlined K-4

I've done several upgrades of the K-Line units to fan driven smoke.  They have all been total upgrades and got ERR cruise and RS, as well as the fan driven smoke and the Super-Chuffer.

Assuming some basic skills, how hard is it to do

Well, it's not hard to do for me, I guess I have basic skills.   The mechanical work will be mounting the smoke unit and extending the stack.  I use brass tube soldered to the threaded cup and cut to length.  For the mount, I have aluminum sheet that I cut and bend for a custom mount for the smoke unit.

John, the parts used are worth more than the K-Line engine.  On the other hand, doing it that way is the hot set up.  I have converted many to DCS with a fan driven smoke unit.  Again, a guy really has to be in love with the engine to dump serious money into it.

Have the smoke unit and fan from a dead dockside, the engine already has TMCC and Rails Sounds.  Overall in my opinion, its better looking than the MTH version.  I only need the CCM, so the cost is relatively low.  The engines slow speed performance is significantly better with the piston removed.  

Appreciate the advice Marty.  I fully understand the concept of being upside down on something.

The piston in any of these affects the low speed running.  For the one posted below, it was originally going to just get cruise and sound, but the low speed performance was so poor with the smoke unit that the owner opted to do the full upgrade.  Needless to say, in spite of the cost, he liked the result.

Ignore the fact that the video is sideways, I couldn't get it to flip when I uploaded it.  This is one of the K-Line semi-scale upgrades, this one got the works, cruise commander, MTH smoke, Super-Chuffer, and lighting upgrades.  It's coming on the outside track after the Y3 trips the breaker and dies on the inside track.

Nice job John.  

Thanks Marty, has the kink in your neck gone away from viewing sideways?

Actually wasn't too difficult to watch that video on my iPad.
