Need post war 624 C&O switcher help

Hi Rob:  The frame of the earlier models (Santa Fe) was a different design from the one you have now, the parts can't match. The casting area around the motor was much lower. Look around for a Greenberg or K-Line printing of the Lionel repair manual, it'll save you from things like this

I have the Greenberg 7th edition manual here. It is not clear at all about the 624 and what is correct. Or, did you mean another type of manual?

Rob

You've got the 1949 NW-2 Motor Truck (622-142), with magnetic axles, and Truck Pivot Bracket (622-63). They are not interchangable with the 1950 chassis and motor.

For the 1950 NW-2 chassis and motor you have you need Motor Truck 622-174, with seperately applied magnets, and Truck Pivet Bracket 622-188.

The top of page 61 in the Greenberg book shows the difference between the 1949 motor (622-100X) and the 1950 version (622-100)

Thanks Len, that is what I was afraid of. The motor truck bracket is shown with conflicting numbers in the Greenberg book, Lionel service manual, and Olsen's site. I have the 1950 motor as shown in the Greenberg book. I  need to find the right truck now as well as the right truck pivet bracket. Rats!

Rob

The 1950 Truck Pivet Bracket has curved front edges, as shown on page 60 of Greenberg, you have the 1949 version with the straight edges shown on page 58.

I found out the hard way the hole spacing is just different enough to make them not interchangable.

A 624 should be the same as the 623 and 6250. These all differ from both versions of the 622.

It was frustrating that The Greenberg book, Olsens, and the lionel service manual pages all did not agree with each other in part numbers.

I posted all of the "Corrections From Previous Editions" to the appropriate places in my Greenberg book, and it's my "bible" for servicing post-war locos. In 14 years of operating my repair shop, I've found if there's a conflict with other sources, it's usually the other guys that are wrong. YMMV

This is a bit off topic, but am I the only guy that likes the Western Maryland NW2? I just serviced one of these for a friend, it has all of the premium features of all the diecast frame postwar locos, runs super and pulls well. The only downside is the plastic driven gear in the power truck, but that can be changed when it fails, and replaced with a brass gear. Of course, you have to be a postwar guy to like these in the first place. No sounds, no TMCC, what fun is that? LOL!
