My Senior design project - a "Swamp Thing" tracked vehicle clone

[Garauld]

I've been working on simplifying the wiring harness by pulling connector pins/sockets. I finally got the knack of popping the latch holding the pin/socket in the housing. My cheap set of eyeglass screwdrivers work better than the $11 set of EBay connector tools I bought.

After a few days of hacking and chopping wires I got the engine harness whittled down to where it cranks, sparks and the fuel pump runs all without blowing a fuse nor causing any conflagration (fire). Once it warms up a bit, I plan to roll the chassis outside, add some gas to the tank and see if it runs. :thumbsup:

Thanks for keeping us up on this Garauld. I'll post a photo of my tracked machines if you like. We have snow here.

Here is some machines that I've operated over the years. Only the 6x6 is mine personally which is the last photo...

Copied from PBullys web site. Its sure hard to copy and past here! In the below info you can see they a hydrostatic transmission. The new ones might have 5 or more pumps in them.

Cool thread! Nice job!

It is a nice day here in upstate NY so I rolled Snowzer out of the shop in an attempt to see if it would run. After putting a couple gallons in the fuel tank and a bit of cranking, viola - it actually ran! :thumbsup: I moved the shifter arm through its paces and the axle CV housings moved appropriately. I do have a small atf drip leak that is probably located where I split the diff housing to I weld it up. This will need to be addressed at some point.
