Jeff T posted:Some great comments in this thread!! Should I chose to do a proper rebuild of this old pullmor, is there a guideline to follow?
Get it clean; bearing clearance should be less than 0.0015"; and the commutator should be smooth, flat, and square to the shaft. For best operation, replacement parts should be postwar, not reproductions or modern Lionel. Replacement bearings should be oilite, not 360 brass. Brush diameter should be 0.180" max and 0.178" min. Do not strip the oil out of the oilite bearings with volatile solvents. Soak bearings in 0 or 10 weight synthic motor oil for several days prior to reassembly. If replacement bearings are installed, they will probably need to be reamed to size. Use no WD-40 or lithium based grease.
