- If you like my work please comment, like, and subscribe to let me know and I'll start making time lapse videos of the processes I go through in which to hand craft and refurbish old items laying around to make the parts needed to accomplish my creations, thanks everyone hope you enjoy...✌️😎
I would love to see more videos on this machine. Very interested in how you made the front sprocket setup.
Hi Nice swap you did would like to see more on the front sprocket swap how you made the cover and were the sprocket came from and the rear hub set up cool and thanks.
It was a shaft driven atc so after removing the transmission and everything that went to rear axle I was left with typical chain driven drive shaft sticking horizontally out the side of the engine but it stuck out twice as far as a chain driven engine to accommodate the transmission assembly. The hole around the shaft leading into the engine was also bigger than it is on a chain driven engine and I couldn't find an oil seal rung with the proper dimensions to accommodate the opening, so I cut a 1/4" thick aluminum plate and made bolt on where the transmission bolted on with a hole drilled in it that was the exact same size as the shaft in hopes of retaining the oil. If I had a lathe or something I would have made the hole the exact size of the oil seal so it would have been proper of course. But it worked enough that I was able to make it work for short distances lol. The other issue I faced wasthe shaft itself had a hole through the center of it to allow the oil to flow through so I welded the typical chain driven sprocket onto the end of the shaft but I only had a small 110v hobby welder that wouldn't get hot enough to seal the center of the shaft for some reason so even though the plate I made was preventing oil from coming out the shaft itself constantly pissed oil no matter how many times I welded it. The design would have been perfect with the right equipment to complete the job. The shaft stuck out just far enough that the chain had a direct straight line to the rear sprocket even with the oversized tire and swing arm, eliminating the need for a jack shaft like most big wheel bikes
@@jagsjungle4631 ok thanks I know what you are saying about having a lathe I would of turn a shaft to press in the end of the shaft to plug the oil hole and what did the front sprocket come off of to fit the shaft splines do you have any more build pictures or video to show more on this cover and the rear sprocket hub set up thanks.
The front sprocket came from princess auto and was just a typical 250cc dirtbike front sprocket and the rear sprocket came off a 250cc dirtbike that I took apart to build the big wheel bike and a go kart. I used the engine for the go kart and I used the rear swing arm and sprocket for the big wheel bike. I cut the swing arm and re shaped it to go around the big bigger tire and I used the front tire and hub for the rear tire and I used the hub off the 250cc dirt bike and removed the spokes then attached it to the front hub of the 3 wheeler tire to extend it out enough for the sprocket to sit outside the tire

I don't have detailed pics of how I assembled the rear hub and sprocket but I sent the pics I did have. And thatcwas the other thing I used off the 250cc dirtbike. I used the 3 side panels off each side and connected them all to be the side plastics for the big wheel bike 😅
Do you lose reverse with this? Awesome work, very clever!
It lost reverse because I removed the case that housed the high, low, and reverse functions that went to the shaft that originally drove the rear axel. I welded a sprocket onto the end of the shaft because it stuck out far enough to line up with rear sprocket. I also made an aluminum plate to go over the shaft and seal up where the transfer case was mounted. Unfortunately it still leaked oil excessively, so I took another incomplete engine apart that was the same make, size, and year but was originally chain driven thinking I could use the oil seal that went around the shaft but it ended up being too small. So then I put the 2 different engine halves together with the shorter chain driven shaft and made a jack shaft to go to the rear sprocket but of course they weren't exactly alike so it worked but still leaked oil. I was going to weld the 2 halves together but I don't have a good enough welder for welding aluminum unfortunately
