There is a "dog" on one end that must drop into the provided slot to "seat"

If they've placed the motor in wrong, and that dog isn't in the slot, it won't seat.

 

Also, make sure the tabs are on the correct side of the buss bar rods, and they have to drop into shallow slots.

 Prior to sending it off, since this will most likely happen again, play with it a bit so you're familiar with it.

Thanks for all of your advice on this Curmudgeon, the motor is most certainly not seated right but I can't get it back in. Never mind, I'm sending it off for repair in the new year.

Cheers,

Kim

With the truck sitting on it's flanges, bottom cover ON with center screw installed, the motor drops in, with an alignment dog that only allows it in one way.

Make sure it is seated down tight at both ends and that the driver alignment is visually quartered.

At this point, make sure the motor tabs are making good contact with the vertical pins.

 

Follow the directions for dropping the chassis back onto the truck.

With you now, I thought you meant some other screws. I'm going in today for a good exploration. I've already lubed this loco so I may be the cause of this. How do I get the motor back into alignment? I'm sorry if I'm sounding thick on this but when I do things like this screws get lost and springs do waht springs do!

Bottom cover, right down the middle, can't miss them.

That's the problem.

You pull all three to drop the cover to lube, that also frees the truck from the top plate, which, as I said, if it ain't exactly level and you don't take extra caution, will dislodge and most likely allow the motor to drop out of alignment.

That's why this is the only engine series (Sumpter and Uintah) that I keep ready-spares gears for.

I'm afraid I don't know where these screws are, I take it there's downloadable schematic on the LGB site. So, does the motor come adrift from its housing, if so, what sort of stupid design is that?

Cheers,

Kim

At this point you may want to drop the truck.

#1 and #3 screws will drop it (if I recall).

 

Check the motor and gear alignment carefully, set driver quarter, place motor block on track (or level bench work), sit loco down onto engine, grasp by siderods to holed engine against loco, turn upside down, place screws......

Hmmm, this is food for thought. I take it the motor sits centrally and drives from each end. The front gears that drives the front axle spin freely with no resistance at all, this would suggest that the motor is out of alignment, or the worm on the motor shaft has stripped. Definately one for someone with experience.

Thanks, Kim

The trick to lubing them is to place them EXACTLY level upside down, and when you remove the bottom covers, HOLD the drivers against the boiler to keep the motor block against the top plate, lube, and re-install the cover.

If your drivers (one and three) are not visually aligned, lift one and turn it to visually align.

'missing the drive cog' - sorry, should have said not making up with the motor drive cog from the motor. Here what you are saying about these beasts, the guy who's doing the repairs is very good. I bought the unit second hand over e-bay so I don't know who's responsible, me or the previous owner.

Kim

"missing the drive cog"

 

You mean the gear was not installed from the factory?

 I will say, out of all the locomotives I operate, or work on, the ONLY ones I keep ready spares for motor blocks is the Uintah/Sumpter.

You drop the bottom cover to lube or inspect without knowing what you are doing, the housing shifts, motor drops out of alignment, and re-assembly results in stripped gears.

Good old Sandy at Scottish Garden Railways is going to do the repair from me, in fact he's doing both bogies for around £100. That'll do for me. Not a quick fix with LGB's shaky delivery at the moment but it will be a lasting one - I hope!Thumbs Up [tup]

A lovely day here in Blackpool yesterday so I got the mallet out for a run. The speed was way down and it was jerking when running. Onto the bench it went and whilst each truck worked on the rolling road when I turned it upside down the front truck was missing the drive cog, confirmed when I opened it up. My question is, is there a quick fix for this?  or do I send it to a dealers for repair? I have e-mailed a local-ish dealer to find out a rough cost but if there's en easier way...........................

Cheers,

Kim
