Hayes HD dump truck...RCP's style

[RCP57]

I made a little progress with the driveline today. I didn't want to use a stock trans because it is so bulky and high geared. My attempted solution was to buy a cordless screwdriver and tear it apart. The one I bought came from Walmart and was only $10. It is a nice little planetary setup and seems to have enough power to spin all 8 tires on my bench with a few pounds of weight on them. I made up a little mount for the drive itself and bolted it into the frame. I used the 1/4" hex coupling, slotting it with a diamond wheel to allow fitment of the stock driveshaft. If it all works out I will have plenty of room for batteries and electronics under the hood...

Hi Reg that was a great idea. I saw it on You Tube and it looks like it fills the bill. Ed

Thanks Ed. Only time will tell if it holds up but I think it will work out fine. It is easy to swap out so for $10 I will buy another as a spare just in case. After joining the other island boys at the show in Campbell River I figured that a slow truck was way better than a fast one. Being set up on tables is just fine but a little bit of a concern when your truck doesn't like going really slow! My KH has an 85 turn motor with an 11t pinion and it is still way too fast to ever use 3rd gear. At shows we are always in a confined area so there isn't much need for a big, bulky 3 speed. This drive should have an output speed at the axles of around 120rpm at 7.2v. It looks to be just a little slower than my KH in first gear.
