altenator on my fcub
First my '52 fcub came with it changed. My question is has anyone changed the pulley on the alternator to the larger vee belt so the fan and engine pullies can turn the alternator with one belt instead of using two belts?
I'm technically misunderstood at times i guess its been this way my whole life so why should it change now.

Re: altenator on my fcub
I don't know of any reason not too, but don't forget you will also need to extend the alternator shaft or reposition the alternator to make the pulley line up with the others.
If you are not part of the solution,
you are part of the problem!!!

Re: altenator on my fcub
I don't see the purpose considering the inexpensive cost of the belts. And considering that the belts last for years.
If the alternator is working, leave things alone.

Re: altenator on my fcub
The PO cut the hood so the alternator would fit instead of rotating the rear housing were the wire terminals hit the hood. He could of used a smaller belt on the original two belt setup. I'll use one belt, fab a good looking alternator bracket and install the new hood and gas tank I purchased.
They never take the time to think it out and do it right. The alternator wasn't working at first. He had about 10' of extra wiring. I wired the 10si the way it should be wired and she charges fine now. Next I'll install the one wire kit in the 10si.

Re: altenator on my fcub
If it is charging fine at this time, changing to one-wire will not offer any advantage except if the present exciting method requires an extra manually-operated switch.

Re: altenator on my fcub
Agree with Bus Driver. Use the 10SI alternator until it quits. Then use as a core at the auto parts store for a single wire alternator.
I use to repair alternators. The cost of repair parts versus the cost of a rebuilt alternator with a warranty - - doesn't come out financially.

Re: altenator on my fcub
I purchased the one wire kit and the 105amp upgrade for the 10si. I'm thinking about upgrading all my 10si alternators. I put one on my Hobart gas engine welder too. The stator for charging on the Wisconsin engine was burned out. It's a one wire conversion I did too with the kit I purchased online.

A cub doesn't need a 105 amp alternator. It will run on a lawn tractor battery, It's a 10 HP engine, not a fire engine, with 400 hp, and a hundred flashing lights!

Don't understand the post. YOURS isn't what?offrink wrote:Maybe YOURS isn't!
Original 6 volt Cub's generator only put out about 15 amps max.
All 3 of my previously 6 volt tractors have been converted to 12 volt alternator. Standard Delco 12 volt, 60 amp, rebuilt alternators in stock at the auto parts store. Inexpensive. Even if I have to jump start a tractor, only takes a few minutes to recharge the battery.
I purchased a 2003 Ford Expedition at police auction, previous police vehicle. Turned out that the hulking battery was totally dead. Also the 120 amp alternator was only partially functional. Replace with the same size that came out of the vehicle. Thinking I could have saves some money by simply replacing the alternator with one rated at 60 amps since the lights, siren, and extra whistles had been removed and no longer needed.

Obviously we are well into tongue-in-cheek territory at that stage of the conversation.

Re: altenator on my fcub
i believe you need to spin the alternator at 5 to 6000 RPMs the get max output from it. that is if you need max output, which you don't. the cub at 1800 RPM's high idle is spinning the alternator at around 2500, producing perhaps 30 amps max. thats plenty unless you are running an electric plow.
now my Duramax came with TWO 150 amp alternators (snow plow ready). go figure! for my needs 60 amp will do

Re: altenator on my fcub
A smaller pulley on the alternator will spin it faster, resulting in charging starting at lower RPM. But the smaller pulley results in the belt heating more from the flexing and shorter belt life. Trying to remember if 2 1/4 or 2 1/2 pulley is the smallest practical size.
The Delco 10SI was made in ratings from 37 amperes to 63 amperes (this is subject to correction). Some have been modified for higher output. One of my Cubs has a 55 amp 10SI with the small pulley, a 40 amp gauge. It charges slightly over 30 amps charging a heavily discharged Diesel battery.
