I have tuned many 2343-100 horizontal motors but I am now working on one out of a 2245 Texas Special (54-horizontal motor version) where the motor shaft was totally stuck. I was able to get it to rotate just a bit. I have owned it for about 40 years and as it's part of an almost perfect set I never ran it. I have always been able to clean out the two gears on the end of the motor and put a little oil to those shafts and to the shaft under the commutator where it goes into the housing and get them turning well. This one is really gunked up. How do you clean and lube one that is really gunked up? I suppose I could set the motor vertically and just immerse the two gears in some sort of a liquid like acetone/mineral spirits/auto parts cleaner but this old grease may take something stronger. I know how to get the brush assembly off but not how to get the commutator/shaft assembly apart from the gears on the other end And then pull it out completely to clean it. I haven't found anything on Youtube that addresses this specific motor disassembly. Thanks for any advice you can offer.
Here is a steamer showing the lubricant reservoir - my diesels have the same setup... use WD-40 solvent to get things moving and then flush well with Mobil 1, run, and then pack with Lucas Red 'N' Tacky #2.
To remove the armature, it has to be pressed out of the 2333 M-14 drive gear.

try spraying brake cleaner fluid into the lub hole. (the CRC red can) let it sit for a bit. try to turn it. Keep doing this until the shaft spins freely. a lot easier then trying to get the gear off and the clip-shims and ball bearings off the shaft.
