I have acquired a brand new (well it looks it!) LGB 2080 chassis. It's an 0-6-0 complete with valve gear etc. Now, it has three metal contacts sticking up from the top. I've only ever seen ones with four contacts. The two outer ones create a circuit with the corresponding wheel sets. The middle one creates a circuit with one of the outer ones. What have I got here? My aim is to use this as a basis for a scratch build body, and to make it DCC. Do I need to to split the chassis open to isolate the motor or is it already done? If it is DCC ready, what connects to where? I've looked on line and can find manuals for 2080S and 2080D. But not just a 2080. Any ideas or suggestions folks?
 
I'm not possitive about the chassis you have, however in my experience with LGB motor blocks, the center pin is connected to one of the outer pins via jumper.
 
If it has 3 pins it will be a pre DCC chassis. The pin on its own will be connected to both the motor & pickups. This will need to be separated before use with DCC.

The 2080D is a 2080 with smoke & the 2080S has sound so the chassis are all the same.
 
I've done one of these this week on a Corpet. Basically you have to put another feed into the motor. The three pins are
1 track power to circuit board
2 circuit board to motor
3 On opposite side feeds the motor and circuit board. This is the one that needs to be split as for DCC it cannot do both. The way I did it was to bend the motor tab away from the pin and the solder a wire onto the motor tab. Isolate both wires by using heat shrink isolation stuff, and drill a hole in the top of the gearbox to feed the wire through. You will also have to cut away part of the motor block to alow the bent motor tab to fit back in. I just melted it with a soildering iron. You now have a 4 pin box..............:bigsmile:
 
Thank you Steve, Mike and Dan, Just what I needed to know. The details are excellent Steve. Now if I can just get a weekend without having to work, I can start my 'current project number 18'!
 
One last question gentlemen.....

Can all this be done by just removing the top cover from the chassis, or would you recommend that I strip all the valve gear off, and remove the wheels and then split the chassis?

Indeed, that may be the on;y way (from what I can see) of doing it. I'm just hoping that one of you know a 'magic' way of completing this! I'm not concerned about stripping it all down - just lazy!

If the chassis needs to be "split" that infers an early "clamshell" gearbox. If this is the case then yes you'll need to strip off the rods and remove the wheels from the axles on one side at least to access the gearbox screws. Watch out for the pickup brushes, they'll spring out as, unlike the later "bullet" type, the springs are unrestrained. I think much of the earlier advice assumed you'd got a later gearbox where removing the gearbox base permits removal of the driving wheels, axles and coupling rods as a single unit once the big end nuts are removed to release the connecting rods and return cranks. It's still possible to chip a clamshell but involves a bit more work.

When I did the Corpet loco chassis last week (which is also a 0-6-0 chassis) I just took the top cover off, the motor lifts out and then you can easily solder on a new wire and cut away/ melt away the plastic bit that the bent motor tab will fit back into. There is no need to remove the bottom plate or wheel sets
 
Sorry to drift off topic but I've got a 2080D thats seen better days which I'm trying to resurect. A couple of questions gentlemen. Should the 3 pin gearbox have holes in the top of it or be solid like the 4 pin ones? Also it seems too light (2.2KG),does anyone know how much it should weigh?
Cheers Colin
 
Thank you Neil and Steve. Steve, that was the answer I was hoping for! I've had the cover off and lifted out the motor, so should be able to follow your lead........after the fifth glass of Festive Chocolate Stout!
 
Dear sirs,

There is ONLY ONE WAY to bring back your 2080 series (1974-early 1990s)

You will need to download the proper 2080S Instruction manual (English, German, French language) in .PDF format from the gardenbahn website database.

If you email me direct, I will happily email you this file.

Note: it is VERY important to get this 1980s printed manual. This was and STILL IS the best service manual for older Lehmann steamers.

All the newer instructions are a tragedy for the State of Nurnberg with its history of the first Printing Press.
 
Thanks guys. Yes got it all under control now. The block is rewired and before long I shall be installing the decoders. First job is going to be adding a pony truck and trailing truck, to make it a 2-6-2 prairie. Then I'm planning on modifying a Bachmann Lynn body to create (with some replacement bits from GRS and the spares box) a sort of GW-ish pannier/prairie tank! Photos to follow when nearing completion. I may be a while......... PS. Thank you Metzbahner, I did down load the the manual from the site you mentioned. I'd booked that a while ago. As you say, it's the best reference source.

Check out my blog for 2080 Harzer 2-6-2s. I have dedicated some space on my blog page to the 2080 series locos. I have gutted these many times--ask away. You can also find out where to download the best service. manual.


Regards,


Tom M.
 
Cheers Tom I've got mine running fairly well now thanks, it's going digital at the weekend so we'll see for sure!
Interesting blog you've got there
Colin
