pulmor to pittman motor

Does this motor extend into the cab or were you able to keep the backhead?

Pete

Fits behind back head with room to spare . I did have to grind away some metal for flywheel.

Nice work!  

Pete

Judd, that's a great conversion, but you need to adjust the chuff trigger. That steam sound is horribly out of square.  The exhausts should be a steady and even chuff - chuff - chuff - chuff rhythm, not the chuff-chuff...........chuff-chuff rhythm you have now.

I don't think its the chuff generator. The single red flash is producing two chuffs. Could this be from using an articulated railsounds board?

Pete

Iam using ERR large steam sounds ,4 puffs per revolution 

It's best to talk to Gunrunner John about the chuff sequences. I just got done putting the Chuff Gen. & Super Chuffer about 2 weeks ago in a EM-1 Odessey 2008 version and mine has the 4 chuffs at a smooth rate of chuffing. Did you program your chuffs with the quarter turns, cut the jumper, then shutdown power immediately after the cutting the jumper?

Thats how I did it. I have a 32 to 1 gear ratio so I turned fly wheel 8 revolutions .

It looks like your fan motor is in sync but not the chuff sound. Hopefully GRJ has some ideas.

Pete

What sound set are you using?  I don't even know how you get that sound unless it's perhaps one of the articulated sound sets.

I am using the ERR large steam sounds .

Check the spacing on the C-G, it should be right around 1mm from the flywheel.  Did you disconnect the existing chuff switch before you wired up the C-G?  I've never seen one do that before with the C-G properly installed.

I have the gap at .036 inches didn't have any metric feeler guages. What exactly is wrong with sounds, I have nothing to compare it with. Also I did remove all the old parts.

It's double-chuffing, very odd.  Here's what the chuffs should sound like.

I think I may have it fixed . See if this sounds better ,video may be shaky

That's good, what was happening?

Sounds pretty good to me and I like the fact there are no traction tires so with a heavy enough train you may be able to obtain a wheel slip..... .

The problem was in the tender . I had the super chuffer  output hooked to both the cruise commander and the rail sounds board. So I unplugged connection to sound card. Thanks gunrunner for your great products. I highly recommend them.

Well, that will do it!   You got me, that's the first time I've seen that.

I normally connect through the Cruise Commander, it's a simple one-wire connecting in parallel with the chuff to the Super-Chuffer.  I've change the documentation in the latest production to look like this.

This comment also appears to clarify the usage of HD2.

I guess I got a little confused when I switched out the ac commander to the cruise commander. The ac commander has no chuff input and I was using a cherry switch on the the supper-chuffer an had hd2 connected to sound board. Never thought to unplug it after installing chuff generator. Did project a little at a time. First I used a small mabuchi motor  that fit in the old pulmor motor mount, didn't seem to have allot of power. So I found a pittman motor,ground off the pulmor motor mount and bought a mount From lionel . Has great pulling power now.

Yes, the AC Commander is a special case, but you can work around it.  Pin 17 of the R2LC is the chuff input, so you can just solder right to the socket pin and have the same as the chuff input on the other ERR products.  I don't know why they omitted the chuff on the AC Commander, I need an extra antenna connection like a hole in the head!
