thanks guys. I already have the rear out, on the bench and mostly disassembled. Just haven't gotten the brake pivot shaft out of the way yet. It's stubborn. I guess I'll be buying a new plug too huh... For those who don't know, I'm attempting to replace the gear reduction setup with a...

how do I get the expansion plug out of my 125 hydro rear? Trying to remove the pinion.

maybe I'll add a drag chute. that would be awesome!!!

matt, As far as braking, I'm thinking of adding external brakes with a quick acting bypass lever for the hydro. Some automotive rotors (probably rear, non-vented style) off a jeep and calipers with the mechanical style emergency brake so I don't have to have a hydraulic system. The drag...

actually any vehicle with an overdrive gear has a driveshaft that spins faster than engine speed. Hence, the overdrive name. So basically almost all driveshafts on the road today turn faster than 3600 rpm at some point. Diesels excluded.

It is just gonna be operated on a drag strip. I intend all along to make a driveshaft cage. And isn't the strain on a component transferring a given amount of power more at less rpm than at higher rpm? HP is a function of torque and rpm. If you are going to transfer say 40hp at 1000 rpm...

gee, thanks for all the encouragement...

Dave, thanks for that link. After reading all that I think I'll just leave it stock. Well, it will have a different air cleaner and exhaust. I had thought about switching over to a harley carb (cheap on ebay, everyone wants an aftermarket one) but I will probably stick with my stock one.

Dave, You got a link or something to info about those kits???

Matt, I know I'm not working with the best components for the job, but this project started life as just an overpowered parade tractor. It only morphed into an actual dragster when I found out that they hold lawn tractor drags locally twice a year. I couldn't pass that up. My plan...

Matt, thanks for the calculation help. Actually I hope to put the 60hp to the ground, it is a dragster after all.

If I had to guess, I would say it's about 45hp @ 3600 rpm. If I get crazy with it I can probably get 60hp out of it, but for now 45.

matt, I know. But flipping the carrier wont let me regear and this is a dragster project. I've got a machinist who assures me we can handle adapting a sprocket to the top gear/hydro shaft. I just need to figure out what chain size to use.

I'm thinking of replacing the 6:1 gear drive in my hydro rear eand with a chain drive. It will solve my opposite rotation problem without flipping the carrier and also give me the chance to re-gear. The question is, what size chain do I use? I'm running a 4a084. #50 chain? #60? #80? I...

thanks wayne, but I'm looking for a perfectly round tank. gonna mount it just below the grille on my dragster project. Kinda like the little drag tanks in the 60's. You can check it out on the custom thread.
