91 Marathon (Engine and differetial change)
I'm new to the site so I hope I can get some good info.
I have a 91 ezgo (elec.) I pulled the rear end and battery cage out of and replace the rearend with a 2000 gas rearend with some mods.I have a 13Hp briggs engine that turns ccw.My question is: does it matter which way the shaft on the rearend turns for Fwd or Rev? I know the ratio is a little different , I believe. But didn't know if it would hurt it or not. |

Welcome to BGW!
CCW should be right for the rear end. |

I didn't know which way that rearend turned since it had the Fwd/Rev lever on the rearend . Just didn't know if it would hurt it to go in the other direction.

Re: 91 Marathon (Engine and differetial change)
I have another question . What purpose does the driven clutch do on the rearend? Does it multiply the speed of the drive clutch?

Re: 91 Marathon (Engine and differetial change)
Yes it constantly changes your drive ratio. As the front pully closes in the rear pully opens up at the same time causing a differant gear ration as the cart speeds up. Like an auto tranny, then as the cart slows down as going up a hill the rear will close up slowing down the engine therefore causing the front one to close up causeing a lower ratio. Hope I explained that right?

Re: 91 Marathon (Engine and differetial change)
Something you might consider if your not appossed to a 2 cycle engine. A guy in the yamaha section adapted a yamaha snow mobile engine to his G1 and was able to run the engine backwards for reverse. I need to go find the thread again as I think it was a "bravo" engine. The G1 clutch fit also. just an idea as the 2pg is a japanese engune also and just maybe it would work for an ezgo. I wonder if anyone has looked into this?

I have a 92 Marathon that has been acting up. When we got it a bit over a year ago, bone stock, we did all the typical mods, bigger tires, backin the governor off, clutch springs, etc. I ended up with a cart that did 23 or 24 mph. Not bad for something built almost 20 yrs ago to do 12 mph! Or so I thought. After a year or so of this, something in the rear started acting up. Now top speed is about 13-14 mph. It would shudder or bump as it slows down or speeds up. The engine isn't missing at all, and the brakes aren't dragging. I took the driven clutch apart to check it out, buttons were fine, CPP spring was fine. Belt is fine. Looking at where the belt wears on the shivs & it makes me wonder if their fully engaging right. I've thought about doing an engine upgrade. This one isn't totally without problems, leaks a bit of oil, plus it's the whopping 9hp that really packs some punch The clone honda & CPP clutch is probably what I need to get off my asss & do. Or thought about a Honda 3 wheeler engine & 5 speed transaxle. Even test rode a 3 wheeler on Sunday. Either engine could make this thing a lot of fun. Need to pull the danm trigger. |
