Williams GP9/7 motor and mount

Williams previously offered some GP-9's in pairs with each engine having only one motor. Sounds like this is what you have. The GP-9 will run OK with only one motor but with less pulling power.

Are yoi sure sll the gears are there including the one in the truck block center? Sometimes for non powered units the center  gear and shaft was missing along with the motor.

In sny event you need that motor mount base to hold the truck to yhe frame. Bachmann still sells the 4 wheeled power trucks and reverse if you want to ad a second motor to your unit.

Yes, the gears are there. It was sold as a set with one listed by the seller as being a "dummy", and the truck wasn't attached. Price was good even for one running one, so I went for it, but if I can get 2 units up and running, or even one powered unit and one dummy, I'll be ahead of the game. Any idea if the motor mount base from a Lionel will fit the Williams units? They're less than $10 from Lionel, so that'd be my first option (haven't come across any for sale elsewhere), as it could at least be pulled in a train. Don't need a reverser, as any powered unit will be converted to TMCC.

Does Bachman have a site where they sell parts, or would they need to be contacted by phone? Thanks!

Timko repair depot ask for frank 1 937 429 1461 if he can't help you nobody can

Sorry but I doubt the motor mount base for Lionel will fit in  Williams keyed frame. The closest key I saw to a Williams was the latest Weaver dual motor setup. The Weaver motor mounts are close but will not fit [slightly too big] besides a filing of the key hole in the frame.

I just went on yhe Bachmann parts site for Williams. The powered truck block [which is the same for many other Williams 8 wheeled diesels] is only $28.99? Need a coupler with it then its $41.99. Need s motor mountb TY o lock in The truck to the frame thats only $7.99 found under universal parts. Whats wrong with that?

Googled them and found the site. Geared trucks are sold out. Thankfully, I don't need one. They don't even have the GP9 motor listed, sadly (808-E002, in case anyone else is looking). The motor mounts will at least get it on the track and pullable. They have 2 "universal" motors in stock, one with long wires, one with short (length is irrelevant, as are the connectors, for my application, just need something that'll drive the truck) listed as for the "Dash 9, FM Trainmaster, SD-45, SD-90, FP-45, U33-C". They also have another "universal" motor for the "E7, PA-1, EP-5" (all of which have 6 wheel trucks), but that's sold out too. Looks like I'm going to have to pull the existing motor from the one unit and see if the gear looks like it's the same length as the "universal" one.

Here is what the Williams single motor GP-7 looks like with the shell removed. Not clear how a second motor could be added.

Not clear? You have to unscrew the reverse board and push it back in the long area so the motor mount holding the truck has air space. Once that happens now you can mount the motor to the motor mount and there is your dual motored unit.

I can help with the motor mount. I have several from locos I upgraded to powered units. They are the same part. Send me an e-mail if interested.

As best I can tell, most of the motors are the same. The F3's have a thin/wide flywheel and won't work in a narrow hood diesel shell. All of the others have a thick/narrow flywheel and should fit. The difference will be in the harness which is important if you just want to plug and play.

Frank Timko has good motors for about 40 bucks. They may actually be better than the Williams and there may be a difference in current draw and rotation speed. I don't know if the difference is enough to cause issues. Frank can let you know if they can be used with a Williams motor in the same loco.

Looks like at the moment, I'll either be able to (if the "universal" motors fit) get 2 engines running with 1 motor each, or 1 engine running with 2 motors, as there doesn't seem to be any current source for Williams 4 wheel power trucks, so I can't add motors to each of them. Each unit I have has a motor and a dummy truck. If I order a motor (either from Williams or Timko), it'll come with the mount, so I should be good there.

The twin Willams GP-9's I have as received ran well together with each having one motor. I did some experimenting with control of the two separately mounted motors using a single electronic Eunit and as expected eventually went wireless. Still working well today. These are good engines.

Motor finally arrived from Bachmann ("universal" with long wires). Frank Timko never answered my email, so I went with them. "Universal" motor, not so universal. Seems the gear on the motor shaft is too long for it to correctly mount in the GP9 truck. Does turn the wheels. I'll have to pull the existing motor and measure the gear length, and see if I can cut the new one down to size.

I think I'll end up putting both motors in the one engine, and then see if I can just swap the shell from the other one onto a Lionel SF GP9 with TMCC that I'd picked up at one time for either a project or parts.

There are two types of worm gear motors for Williams the four truck loco's are short and the six wheel truck are long.

I should have the parts you need. short gear motor and motor / truck mounting block.

If you are a Williams fan there is a good Facebook Group.

I appreciate the offer, but since I already have this motor, I'll cut it to the correct length. It's about .192" too long. They no longer have any motors listed as available for 4 wheel trucks.
