I repowered one of these FT's with a Mabuchi can motor, replaced the noisy couplings with fuel line tubing and quieted the worm shaft bearings by laying thin rubber sheet at the bottom of each slot. After tucking lead weights into just about every gap in the frame, it rivals a super-weighted Athearn F in weight and pull, and is significantly quieter.
As mentioned earlier, it's too long for an FT since AHM just had Kader use their F9 chassis.
Itsme, what do you need those springs for? I assume a brush spring for the open frame motor?
The springs are to be used, successfully I hope, in a pre-war Roundhouse HO scale 0-6-0 Shifter. The motor actually runs but the springs had lost their sprung tension, so new springs are called for. Over the next few weeks as I get to installing them and finding/repairing the original bronze worm, I'll update everyone with a new thread over on a more appropriate board.🚂
Here is a picture of the motor, circa 1940, courteous of hoseeker.net
Wow, that is an early one. I didn't know they went that far back.
They did, along with Mantua and Varney. The big three in HO at the time. Pioneers. Soon after, all three, and just about everyone else in manufacturing, had to stop because of the shortage of copper and nickle. But most survived because they offered to make military hardware instead. Everyone won. The manufacturers because at least they had income coming in rather then idled machines, and the government because they didn't have to go far to find machines or help set-up new facilities.
All the manufacturers had to do to get things rolling was to make new dies according to the military's specifications and install the dies on the machines they already had. Like changing out different drill bits on a drill. 👍🏼
I know this thread kinda went off course and I apologize. I wasn't born for another 19 years after the war ended, but besides the revolutionary years, the WWII era is my favorite part of American history. 🇺🇸
The second generation of Bachmann F-Units are the subject of these additional posts. After Kader had manufactured the decent 8 wheel drive units for AHM and Bachmann, They developed some 4 wheel drive F-Units that were true wonders. The drives had 4 wheel drive pancake motors, traction tires and 4 wheel electrical contact truck. They were true wonders, That is. it was a wonder they could even make it around the track at all. I submit that these were truly the Dark Ages for Bachmann. These F9 units had a couple of different frames, and at least 3 different body shells. In addition to the F9 they also offered the improved FT shell that AHM introduced. No B-Units for the FT or F9 were offered in this era.
The first shell is very close if not the same as early 8 wheel drive engines The second shell is similar but lacks the steam generator stacks and only has one headlight The third is very close to the second shell except it does not have a hatch for the last radiator fan

This is a set of notes about the third generation of Bachmann F-Units. It is not and overview, but about some new improvements. The Third Generation started with the Bachmann Plus line and has seen changes since then. The Bachmann F-Unit drives have replaced both my Athearn & Life Like drives. This is due to cost, reliabilty and availible of resonably priced parts.
While looking on eBay I noted that the newer Bachmann F7 B unit had new couplers that allowed closer spacing. I did some research and put together this drawing.
I will pair the New B units with an existing A unit by swapping the new close couplers and trucks to the place between the A and the B units . I am not going to worry about the front and back couplers spacing on the AB Set. I just hope they are the latest production and have the new couplers. Regards, john

Just wanted to say thanks for putting this set of research posts together. I've got several Bachman engines an this is a great refference for comparing their differences. Unfortunately they are almost all pancakers, but with some cleaning and lubing I've got them running pretty good.
umpdan31: I get it now. If the black Hills of South Dakota has a white crow, is his name Blackie? (Nothing racial intended. I'm talking about a bird. When I was young, we had a black Cocker Spaniel named Blackie.)
