CUSTOM MANUFACTURED UPGRADE/REPLACEMENT GEARS
Gears are very specific with a vast number of variations which makes it very difficult to obtain a replacement for an older and craftsman
made product. Often the gear(s) were made specifically for the model and spares, if any, are no longer available. To aid model craftsman in
repair of such models, NWSL, sometimes with the aid of a sponsoring modeler, has manufactured a large selection of replacements, almost
always of better quality and choice of material. When you find a model with both worm and wormgear of brass, the wear rate is going to be
very high on one or both gears—for improved gearing life, the wormgear should be immediately be replaced with a delrin gear before (the often
irreplaceable) worm is destroyed. The vast variety and the specialty of these gears makes their handling cost extremely expensive on a unit
basis, thus to aid NWSL in keeping their (and your) cost to a minimum, you need to determine what you need and wade through the list to see
if you can find it. You do enjoy hide-n-seek didn’t you?
These custom gears are in the 300-6, 1000-6, and 2100-6 series. Geared upgrade wheelsets can be found in the 2500-6 and 2600-6 series. See
the current listings in the blue product list pages at the rear of this catalog or on the NWSL website www.NWSL.com.
When the original gearbox is of questionable serviceability (and would probably destroy the replacement gear), consider the various NWSL
‘generic’ gearbox kits (page 4-9, etc.) which can save just about any model steam locomotive and some diesels.
For gears you can’t find, inquire direct to NWSL with as much information as you can determine—# of teeth, OD, ID, type (ie. SpurGear
(|||||); Wormgear—RH(/////); Reverse Wormgear-LH(\\\\\) - it can often help to know the application (where you found it).
Keep in mind (1) the attributions shown are where we (or the reporting modeler) found the gear—it may also appear in other models; and(2)
different units of a given model, even though from the same manufacturer, may not have the same gears—some models have been repeatedly
made with the same gears, others have changed gears in subsequent production runs (we have even found an instance of changed gears in
models from the same production run!).
NOTE: Many of these gears are not on our online store.
If not found online, please call 406-375-7555 to order.
