I picked up this Mantua F7 from eBay, and when opened I found that the front wheel frame is broken. Does anyone know where or if I may be able to pick one of these up? Hoping someone can help, I really want to keep this for a future project.
Thanks Blane

I may have one in my parts bin. I'll have to check when I get home.

I have a couple of different ones, post a picture showing what the side frame looks like.

Well,I see your problem right off the bat - that is NOT a Mantua! Or a Tyco. at least, not a vintage one.  Hard to tell without a further close-up, but that's not how the (original) Mantua is designed. Does it say that on the center weight? Looks like a bachmann to me.

That's what I was thinking, that it looked just like a newer Bachmann.

| Hey Blaneo, Picture looks like you might have all the pieces there? While you're waiting to find a new part, you might try some JB Weld or superglue (sparingly); maybe with some sort of brace you can hide (if needed; tiny scrap) . . . you never know . . . might just hold together. Sometimes that kind of thing works. And sometimes, you can keep the repair fairly hidden. However, I can dig that you might ultimately want an undamaged part.

That would be great, I would certainly appreciate the effort of looking when you have time. Looks as though the GP 20 from the same time period used the same truck frame, so there is a little more hope.
Thanks Blane

Here is a couple more photos. And yes it is a Mantua, from the 90"s.
I thought about using some type of adhesive to see if it would hold, and I will do that. The frame snapped apart right at the clip that holds it all together. So I think it will probably just snap again once I apply pressure to attach it back onto the gearbox. But we will give it a try.

Interesting! Dead ringer for a later Bachmann at first glance, but much clearer there.

Yes, I have a couple of newer Mantua engines, but all steam, not diesel. First time I'd seen a '90's Mantua diesel before. Nothing like the originals. Wouldn't mind seeing more details of the motor drive system on it, either.

It is very close to the Bachmann. So much so that I started looking at their frame to see if it would work. I do have a few of their engines, and the frame looks as though it might possibly work. The detail of the frame is different, and the Manuta has the truck mounted coupler. The Bachmann has a body mounted coupler, but that frame looks as though it might slip over the coupler tab on the Mantua truck. I will take a photo of the drive when I get a chance to take the two apart and see if that frame will work. I would still like to have an original, and I may just have to pick up another model to get it. This is the second of these that I have purchased, and of course I can't test drive this one, but the first one runs nice and smooth with no hesitation at slow speeds.

Didn't get a chance to dig through my parts and will be heading out of town for a few days. I'll take a look Sunday when we get back.

| The 90s Mantua locos were great runners. Pulled great. Smooth motors.

| Can you possibly glue it while it's in place . . . so that you don't have to pressure it too much to put it in place after it's glued?

What I have is close, but not quite. I'd try gluing in-situ and see if it holds.

I'm with JNXT Jerry, I would like to see the body off and look at the drive train. This model may be different, but may share parts with other brands.
Found info on Mantua F7 on line. Looks like a Mehano drive. A truck from an 8 wheel drive EMD truck should provide parts. MP F2, F3, or LL GP9 or IHC/AHM GP18. Make sure the truck is from an 8 wheel drive mehano model. This is an educated guess.
Regards John

Hey Blaneo. Try some Testors Plastic Cement. It comes in a little bottle in liquid form with a brush. You brush it on the surfaces you want to bond and then hold them together for 20 seconds. It basically melts plastics together. I've had good luck repairing cracked and broken plastic shells, buildings, ladders, etc.

| Yeah, that liquid "weld" can be good given the right fit of the pieces. It will melt them out of shape, though, if you don't get it right in the first couple of tries. On the other hand, super glue can be carefully peeled away to "try it again".

Sorry for the delay, but I had to wait and see how the seller wanted to handle this issue. They offered me a partial refund for the problem.
I tried the testors liquid plastic cement, and it did a great job of putting all the pieces back together again. But once I went to snug up the coupler screw I heard a snap. Luckily the truck frame didn't snap apart, only the section where the screw goes into the truck frame. Which as soon as it happened, I realized that there shouldn't be any screw holding the coupler in place. I don't think the hole is the correct size for the screw used. I don't know why I didn't catch that before. As you can see in the first photo, there shouldn't be a screw used to hold the coupler in place, there is no need for it, the truck frame would have held it in place on it's own. I think that whoever did the coupler swap actually broke this to begin with, and that the seller and I just happen to be the lucky recipients of someones wrong doing. Any way, I think it will be okay now, as I have made a few laps around the oval with it, and the truck frame has held together. I do plan to add a thin piece of styrene to the top of the truck frame to reinforce it when I clean and lubricate the model before adding a decoder to it.
Pics two and three show the drive line for those that asked.
Thanks for the help and comments.

Thanks for posting the pics!
First look I have had at one of those Mantuas. Looks pretty stout! I've been on the lookout for them lately

That's the late 90's red box Mantua with the Mehano drive that I spoke about in the other thread. This is what ran at Northlandz, and Tyler mounted a huge ad campaign to promote them. That's why he was distancing the company from 70's CF Tyco and the old pancake trucks. I have the GP20 version, and it's a very smooth customer. They finally wound up in the Model Power line of locos with reduced chassis weight and minus the Flywheel, IIRC.
The trucks are the same as old AHM Mehano. Unless they made some dimensional changes, the Blomberg sideframes from an old AHM GP-18 should be an exact replacement.
