Dismantling a Rugen 0-8-0 - hours of fun (NOT!!)

Just finished off a very lengthy job, started yesterday, of dismantling my green Rugen 0-8-0 (LGB 28002) to replace its ageing factory-installed decoder with a new Massoth L, and then reassembling it all.
If you ever think about taking one of these apart, my advice would be DON'T unless you absolutely have to - I've never had an LGB loco that was so difficult to get into and then get back together again! Being a well-tank, the boiler is a one piece tube with a huge weight slid into it, the factory-installed sound board sitting on top of this with the MTS decoder directly plugged into it piggy-back style (like all LGB locos with a "direct decoder" sticker). The tricky bits are all the various plugs and leads that have to be connected to the sound board at both smokebox and firebox ends, and then all the mass of boiler external gubbins and pipework that looks so lovely but is an absolute b*gger to relocate as you try to slide the cab back into place! Finally managed it all accompanied by much swearing, but I really don't know how the LGB workers managed to assemble these things on the production line, since some operations seem to need at least five child-sized hands simultaneously (maybe LGB had cornered the market in 5-armed mutant child labour.....).

Anyway, all done now and it's running nicely again (thank the Gods), but it's not a job I'd want to do again in a hurry, or recommend that anyone else does if they could avoid it! ;)

Maybe one of those spiders near where I work would have been helpful Jon....
 
Did you pull the top off the dome - this releases loads of bits and bobs to makes reassembly much easier. You then reattach with all the odd bits at the end.
XLS in mine took three weeks because i had a duff board that did odd things with the lights! Jeremy changed it no problems.
 
Yes, took most of the stuff off the boiler in the end, the biggest problem is getting all the leads and plugs to stay in the right places and not get trapped when you drop the cab back onto the end of the boiler. If you were installing an XLS I assume you weren't starting with a factory-sound version, so the boiler space probably wasn't quite so full of factory-installed circuit board! The downloaded assembly diagrams from the Champex-Linden LGB database were invaluable, I have to say.

If I was DCC and sound fitting from scratch, yes, that would be exactly what I'd do; however in this case the loco was already chipped with an early LGB decoder plugged into the sound board; I was simply replacing that with a new L to gain the improved features like the back-EMF. Didn't see a lot of point in dumping a perfectly good LGB factory sound system complete with storage capacitors.
