ADCX Rob posted:The 222-107 is a non-gear grooved wheel for the traction tire, one per loco on the 2-axle powered 2024 My 2024 has a single axle powered motor. I don't know ANY of the part numbers because I can't find any documentation for the 2024 - at all!
(222-101 type motor except double wound field instead of single). Again, no idea on part#, however the motor in my 2024 does indeed have a double wound field, and a 2 pos. e-unit.
The non-grooved non-gear wheel is the 2243-33, and the two geared wheels are 600-137. There are NO geared wheels on mine, just 4 plain wheels, one with a tire groove.
The 634 has only one geared axle, with a 222-107 non-gear grooved wheel for the traction tire and three non-grooved non-gear wheels - 2243-33 - two of them with spacers behind them to take up the space on the axle normally occupied by the depth of the gear surface. My 2024 has two spacers to take up the space on the axle normally occupied by the depth of the gear surface.
A pic is worth 20 or 30 words, as they say...
I know a few people (including Greensberg) have said when looking up this engine "(see 202*)". Well, the 202 (per tandem-associates) had magne-traction, so that's a non-starter, as this one doesn't. And Greensberg's reference material under 200 series ALCOs shows motors with bearing plates and bearing balls, neither of which are on my motor. Admittedly, Greensberg also states there were many variations on motors , so.....
I really would like to obtain the part number for the grooved plain wheel (222-107 you say?), and then actually find the part for sale - no luck so far. The same issue exists on my 1055 which has dual powered axles, no magne-traction and no traction tire, grooved wheels! Honestly, what were they thinking on these two engines? Had to be cost cutting!!!!!
