Got my new UP Challenger the other day thought I’d let everyone know what I’ve found. Theses are great looking locomotives. Came unscathed from shipping.

I’m naturally curious so thought I’d open it up and poke around I tend to put some miles on my locomotives so wanted to be sure all was well.

Pretty clean only two plugs to completely remove the shell.

when I pulled it out of the box I had a run away screw so I was keeping an eye out for where it belonged. Found it in a spot I didn’t expect

the motor mount was missing one screw and was really loose. Got that fixed no harm no fowl yet

I assume this is the additional board for the 4 digit addressing.

I then decided to take a peak in the gear box. There was basically no “grease” in there. I removed what I could and filled with some actual grease.

As is from factory

IMG_3133

all the grease removed from the rear gear box

with that find I moved to the front engine. It was better but still not much

this is the front engine after removing as much as possible and putting it in the top plate.

to cap it off a pinched wire from the factory.

this is hear just as some information for curious minds we don’t need another bashing thread, I like this locomotive it also has two separate parts that were bagged with it that I have yet to figure out where they belong, the manual was no help unfortunately.  One looks like air hoses.

here’s a video from todays run at the club

I have to wonder about this dogbone being almost out of the joint, I'd expect some rough running.

4 digit addressing is internal to the main board, this board is the Bluetooth board, note the BT antenna.

Yes definitely a rough running with the drive like that. That was with one motor mount screw missing and the other very loose. I never ran it like that so no telling how rough it would’ve been.

John I thought the same thing that was the Bluetooth board but if you look under the wires you can see the integrated Bluetooth board with its own antenna on the LCP3 board

IMG_3145

is that new board just another Bluetooth radio strictly for stuff with the new Base 3? Maybe not necessarily 4 digit addressing, it’s just the radio board didn’t look any different than usual either so that’s what made me think that.

Well, their two-way communication capability is bound to require a Bluetooth back-channel, so maybe that's it.  I'm sure that the two-way communication ain't going over the track.

Where is the front bearing?! What a joke! For a $2000 locomotive?

The chances that I preorder a PRR M1 or get an I1sa just keep dwindling…

Did tightening up the motor mount pull in the motor towards the gear box and take up that excessive slack in the dog bone?…..after you tightened up the motor mount, did you check to see how much end play was between the cups?….I’ve had quite a few Legacy big steam that I’ve had to build a better driveshaft ( dog bone) because even with the motor mount tight, the end play was just too excessive IMO, ….a before & after shot would’ve been handy,……

My bad Pat I didn’t even think of an after picture. I was honestly shocked when John pointed out how loose it was because I specifically remember when I was done it was actually pretty tight in the cups very little horizontal movement

You know guys I don’t doubt the Pittmans being superior to the Canons but I have yet to have an issue with any of my locomotives with Canons if I do you can bet I’ll hit Pat up for a Pittman.

you know I’ve seen a Ametek building out by Sprit Aerosystems as I go between jobs. Doubt I could get any motors out of them with out selling a limb.

You said a mouthful right there, …….the rep from Ametek actually came out & visited me, …but it took him all of 30 seconds to say thanks, but no thanks,….
