My expierience with big locos

[Schraddel]

Thank you Wayne and here is a look under the bonnet:


It is astonishing which evolution has taken within a few years. The L-105 Challenger is from 1972 and this M-68 Northern from 1979.
The L-105 had an traditional open frame motor and rubber tubes as substantial parts of the drivetrain.
Here the M-68 have an Canon coreless coil motor and a real brass cardan shaft with massive unviversal joints. Bernhardt (a'ka modelsof1900) will like them






The drivetrain was demounted, old grease removed, nothing was found sticky or faulty. So after an application of fesh grease into the gearbox and fresh oil on alle bearings, the drivetrain was remounted. As it is of the nose bearing type, nothing has to be altered.







A closer look onto the compressors. O.k. there is some plumbing missing, but it is only visible from this angle. When the boilershell is mounted, you will see nothing missing. Thus causes me not complementing the plumbing here, simply because the work will be invisible when the shell is mounted.
