Default Club Car DS 2000.5 Vanguard Stub Shaft

I finally found a 23hp Vanguard to stick in my DS. Has anyone successfully added the stub shaft to the v-twin and ran the motor turned around with a vanguard? I saw a post the other day where someone was running a Kohler 25hp that way but I have not seen anyone with a Vanguard.

I'd be worried about all the stress on that side. That's a lot of pull on the flywheel side. It may not be as bad if your running something off the other side too, but I'd figure out something different than that fix.

Most that build one like you plan use a jack shaft from what I've seen.

The Vanguard only has a bearing on the PTO side. The flywheel side just has a sleeve. The extra stress on that side will not be good for the motor. When the stub shaft is used, it usually drives a drive shaft and has very little side-load.
I am running a stub shaft to drive my supercharger.

People that did that I read about left the governor on the engine so rpm were limited. I don't know, lot of equipment runs stuff off the flywheel. My mower runs driveshaft and 62" mower deck with a double belt right off the flywheel, and nothing off the pto. They can get 4K hours out of them that way. I would make sure there was a bearing in there, maybe vanguards some have them some don't, I dunno this is on an onan.

Vanguards do not have a bearing on the flywheel side. Most have a single roller bearing on the PTO side, some have a double roller bearing on the PTO side. If anything is ever run off the flywheel side of a Vanguard, it has minimal side-load. It's usually a drive shaft going to a gearbox or hydraulic pump.

Then I would not run a clutch off the flywheel side, I agree. I was wondering if the HS gears would be a better deal anyway, by the time you fiddle around setting up a stub shaft you will have some time and expense and stock gearing. The HS gears should end up higher than stock forward gearing right? So if you want more gear you would get some. It would be especially helpful if you used a lower rpm/rpm limited BB. The engine swap would be a straight swap and yes you have to install the gears, but that was not that bad on the CC I did. Yanking the dirty rear out of the cart was the worst so don't forget to pressure wash it first or otherwise clean it up. I stood the rear on one tire and pulled it apart, laid the gears in, strapped it back together, it was pretty easy. That was an older CC about 92 I think. It added about 10mph it would do 28gps with the stock flathead hitting its limiter, cart was all stock other than gears and governor adjustment to go up to limiter.

I plan on dropping the rev kit and a cam in the vanguard 23. I will run as is for a while then see about 8:1 gears for a little more top end. It will be a while before I actually get started with the rev kit and cam. I don't get a ton of garage time with undivided attention to the cart so it will be a drawn out project.

They usually turn out that way anyway. For a lot/most these things are never done as we are always looking to make improvements/mods. Good luck with your build.

the worst part about the gears is the cost. changing them actually takes about 3-4 hrs. pretty easy. would take way more time to build a jack shaft and all that. it works wonderful running the drive train backwards btw
