KLine Allegheny-PS2 Upgrade?

Bruce I have done the K-Line Hudson twice and the Camel back.  You can change the motors to one with a bigger flywheel.  G

I had a K-line Allegheny. The TMCC boards blew up and I asked my LHS about a PS2 upgrade, mainly out of curiosity. They deemed the engine/tender too small to accommodate the boards and it wasn't possible to do. I have hear of people trimming the PS2 boards to fit in a tight place but regardless, the K-line Allegheny is small and it will be a tight fit, if it fits at all. 

Take a trick from engine hot rodders. To check how much clearance you need, take some modeling clay and soften it up. Then place it around the flywheel about as thick as a cylindrical flywheel might be. Then reattach the shell and remove it and see how thick the clay is.

I have a K-Line Allegheny, unless it's a different one, there is plenty of space in the tender for the PS/2 boards!  You could probably also put them in the locomotive, plenty of room there too.  This one has the RailSounds stuff in the tender, and the Cruise Commander is in the locomotive.

Good to know a PS2 board will fit and it can work. I was always under the impression it was too small to make it work. 

BTW - I think I sold you my old Allegheny that was gutted and sitting on the shelf. Glad to see it is back among the living. If you didn't come along, I'd still have it sitting on a shelf serving as a great dust collector! 

It has to be a different model if it's that small that there would even be a question.  You could stack two PS/2 boards end to end in the tender!   There was enough room in the engine for me to mount the ERR Cruise Commander, the Super-Chuffer, and to add a fan driven smoke unit.  I suspect the PS/2 board would have fit in there as well.

Mine was a TMCC version and it already has the fan driven smoke unit.  Definitely will fit.  G

Yep, and when I opened the tender to work on it, I found all the RS stuff already installed.  So, I just added the Cruise Commander, fan driven smoke and all was well.  It later got the Super-Chuffer and is now a happy camper.

Bruce, pull the flywheel and install an MTH 30mm flywheel.  If you need one, contact me.  Do it right and do not Mickey it.

SJC, they hosed you because they did not know how to get it done.  Some LHS owners are great at doing this sort of work.  Some do not have a clue and find it easier to BS people.  Your engine is huge inside the tender. 

Marty, there may be clearance issues with the full sized flywheel.  In addition, you need the proper tools to pull and replace the flywheel, so that's a factor.

John, I know about the tools.

Marty, I know you know about the tools, but you aren't the guy doing the upgrade.  I figured that Bruce should take that into account before trying to hammer the flywheel off.

The flywheel is actually 27.7mm.  I am going to put a hose clamp around the flywheel and fill it to the thickness of a replacement flywheel with modeling clay or silly putty, remove the hose clamp and check clearance.  I am not going to use a sledge hammer to remove the flywheel.

I will try and get or borrow a hobby type wheel puller.  First I will apply penetrating oil to the shaft/flywheel and slooooowy increase pressure on the shaft to remove such.  This has to be a slow process.

I checked the tender for room, can fit two PS2 upgrade boards/speakers inside - no problem.

Any advise on how to remove the flywheel from motor shaft?

A wheel puller is the only way I've been successful.  Fortunately, Henning's has an assortment of them in the shop.

I think the tapered flywheel was there for the clearance, so that may be problematic.

I used playdo to shape the flywheel and there is clearance for a 27.7mm x 7-8mm flywheel.  The Kline Trainmaster has the perfect flywheel for the job, except - the worm gear is different profile than the Allegheny.

Does anyone have a 27.7mm x 7-8 mm flywheel - MTH, Kline or whatever?

That will save me from removing 2 flywheels.

Also - where can I obtain the proper gear puller?

thanks,

bruce

You can swap flywheels or you can swap gears. Removing either is relatively easy. Installing either is not, as its real easy to bend the shaft. What I have done is drill the gear so its a sliding fit then drill and tap for a set screw. Its less critical for the gear to be perfectly concentric on the shaft then it is for the flywheel to be slightly off center. If you have a set of number drills you should be able to get the hole to within a couple of thousandths of the shaft diameter.

Anybody familiar with the NWSL 45-5 "The Puller"?

You can use a 27mm flywheel. Doesn't have to be 27.7.  G
