PostSubject: Right Angle Gearbox   Right Angle Gearbox Icon_minitimeThu May 10, 2018 1:47 am

So im in need of a right angle gearbox for my next build, i have a honda 2cly liquid cooled engine that im dying to use and a peerless 2300 i still have to go pick up from a friend.
Anyhow i want to hook the driveshaft to the gear box then the output shaft use pullies and belts to the 2300, im having a hard time finding a cheap local gearbox so i may just build one myself.
Option 2 is make the driveshaft hook on a peerless 700 i have laying around and make a special pulley off the output shaft from the 700. So the question is would the 700 hold up being directly to the honda? Would the gear reduction be to much and it be super slow? It would be pretty neat tho using the 700 has a transfer case kinda. Let me know what you think, any kinda help would is apprreciated!

I don't think a 700 would hold up very well with a driveshaft from a 2 cylinder engine hooked to it. How would that work anyway? It has a vertical input shaft.

Is the twin cyl engine you want to use horizontal shaft? Because if it is you can just run a belt from it to the 2300 as it has a horizontal input shaft.

Hmm, the way I'm picturing this is with the 700 flipped up so the pinion shaft faces the flywheel of the engine with a drive shaft between the two. Then one of the output shafts of the trans will be able to line up with the pulley on the 2300. I'm thinking that if you mounted the Peerless 700 extremely solid and made a brace for the pinion shaft housing, etc, it would work. The reduction shouldn't be a problem with the shaft drive setup because the pinion shaft with esenctially be spinning the same RPM as the engine basically the same as having a 1 to 1 pulley swap. I think it could work, but you just might want to check the rotation of everything first to make sure you arent gonna have 5 reverse speeds and one forward speed, hahaha.

They can be mounted in any position. Puppetkicker on youtubed used one for a 5 speed go kart with a horizontal engine.

Thanks for the info allis! i still need to get a few parts together before i start building.

Sounds good! Should be pretty neat. What are you planning on using for a clutch? I assume some sort of friction disk setup?

Not sure how the stock honda one is set up but i may use it. Probably going to have one on the belt set up also.

You will still have a reduction through the 700 in high gear, around 8 to 1 when it comes out of the 700. I am sure I am wrong on the ratio but there will be some kind of reduction from the 700 input going to the output. You would have to do the math by counting teeth, then you would have to overdrive the 700 input to compensate in order to have a 1 to 1 from engine to the 2300. Even if you split the overdrive between the 700 and the 2300, the stresses on over driving the parts would probably have alot of belt slippage or breakage. And that would be just having the same speed before and after.

Might be easier and simpler to just have a right angle gearbox that can take the load, and probably cost the same too in the end but be more simpler and more reliable.

Kinda what i was thinking, ill probably just go with a gearbox and keep the 700 for my sears or dynamark.

Maybe I'm missing something here, but why can't you just run the engine direct to the 2300? Not sure why you'd need a RAGB.

I think he wants to mount it online with the frame if that makes sense. It would either be offset or need a jackshaft if he mounted the engine sideways, not to mention really wide

@MatthewD Its the 2cly liquid cooled inline engine i should have stated that. Pretty sure it would be odd looking mounting it sideways on the frame. Im wanting to stick with the honda frame and ditch the stock 5 speed, maybe use it another day but for now i want to use a 2300
