Tonka bottom dump conversion
 

Just finished a conversion on my tonka mighty bottom dump truck, thought some of your would like to see it. It dumps with a firgelli actuator.

That's a pretty cool conversion, nice job :cool:

Re: Tonka bottom dump conversion
 

That's very cool!

Can we get some pics of what's been done to convert it?

Re: Tonka bottom dump conversion
 

Efroeh-
Your Tonka conversion looks GREAT! I'd like to convert my '68 Tonka Earthmover/Scraper/Pan someday.

Neat. That's a Tonka I didnt have...

Re: Tonka bottom dump conversion
 

Ya, very neat! Would love to see more about the conversion and some action video hauling aloud! Thanks for the pictures!

Re: Tonka bottom dump conversion
 

Thanks I will get some more pictures for you guys and will explain how i did it all. I also will be doing some videos here in the near future.

Re: Tonka bottom dump conversion
 

Got some pictures today it was raining out so no in use videos. For the conversion I try to buy a used axial scx 10 scale truck. Basically tear it down use all electronics full axle assembles. Uses some aluminum to attach it to the frame. You have to cut some of the tonka frame down so the axle will sit were the tonka axle did. To move the bottom dump open and close used a firgelli actuator attached underneath to the closest one and a peace of aluminum attached the two openings. If any more question just ask. ( it makes sense in my mind but that doesn't mean it does for everybody else haha) on to pictures

The rear axle had to be narrowed so it would look proper.

All the electronics are under the cab for a nice clean look

I like it very clean and simple. As you start using it I am interested to see how well it works with out suspension travel.

Re: Tonka bottom dump conversion
 

I've used my tonka dump truck it's built the same way and it works great. You don't wanna set any speed records with it but it hauls heavy loads easily. I tried doing suspension when I built it. And it was impossible to get suspension and have it look like it wasn't converted also was hard to find something that would work once you put 30 lbs of material in it.

Re: Tonka bottom dump conversion
 

I've never seen a Tonka like that before... Great work on the conversion :eek: :cool:

What's the dimensions of the payload area?

Re: Tonka bottom dump conversion
 

Thanks I've never seen one either till ebay got ahold of me haha. The dimensions are 5 inches wide 11 inches long at the top. 7 long at the bottom and 5.5 deep to the opening in the bottom. It'll hold little over 4 liters of pea gravel.

Re: Tonka bottom dump conversion
 

Nice conversion - think she needs geared down some.......
Nice work :cool:
(Scouting ebay too now!)

Re: Tonka bottom dump conversion
 

Ya the truck I used for the conversion is brushless needs a good brushed motor will help with torque.

Re: Tonka bottom dump conversion
 

Nice conversion! Not sure what type firgelli you have, operated by (RX or esc) but if your on a self centering stick or 3 postion switch with the "R" version (RX) you can grab a camera positioning module to hold the actuator at any place in the stroke. Could help with flow control out of the dump.

Re: Tonka bottom dump conversion
 

It's is the r version. With my spectrum reciever I can choose either a 2 position or 3p or linear which is basically hold the switch for as long as you want it to move. I just need more practice and I think I'll try a 3p next and set it for when the gravel is flowing at a even flow to drive. Just more work (play) time with it. I will get better practice when my excavator is back up and running had a track motor go on me.

Re: Tonka bottom dump conversion
 

Right on. Ahh man, been there. My 4200xl arrived with both gearheads crushed up. Still not sure on the story behind that.

Re: Tonka bottom dump conversion
 

Ya I think mine is similar it won't even move the track on that side. It's at my lhs he's gonna contact then and fix it up. Also have one ram leaking gotta fix also. But I do enjoy that machine

Re: Tonka bottom dump conversion
 

Yup, real fun machine at the price point. Nice your LHS will do that for you. Think if I showed up with my 4200 at the LHS they'd have the deer in headlights look. 4200 is fairly easy to work on considering the size and room to work with. My track motors arrived looking like this and a vid of what was happening.
