I want to retrofit an auto alternator to my B7300 to handle more worklights. Anybody done this? What brand would work? Will the OEM 3/8" pulley swap onto anything? I'm thinking an internally regulated one would be simplest.

Kubota L5740 HSTC3 and a Kubota ZG222Z, 2013 BX25D,Custom Toyota fork lift.
I've done many alt. swaps in the past. I always use the GM alt. I've installed them in old military Jeeps, boats ans when I rebuilt my forklift the stealer wanted $600. For an alt. so I installed a rebuilt GM alt in it for $120. and it works great.
Here's some info.
Delco 12-SI: The Delco 12-SI alternator, introduced around 1983, was a replacement for the 10-SI. The 12-SI alternator has the same outside dimensions as the 10-SI and will fit in place of a 10-SI without modification.
The 12-SI improvements over the older 10-SI model include:
6 large cooling holes at back for better cooling of rectifier, stator and other internal components ;
High volume axial turbo fan for greater air flow through the alternator;
Larger rectifier to handle more amps;
Wider stator and rotor for improved magnetism for better low-end output;
Increase in mass helps with heat dissipation.
The 12-SI alternators are available in 56, 66, 78-, and 94-amp versions.

You can get a kit from Kubota to upgrade to a 35 amp alternator for around 200 dollars. takes all the guesswork out of making something work! (bastardizing!! LOL) That being said I have retrofitted delco 12-SI's to a lot of different equipment over the years!

OK, now I know a 12-SI is what I'm looking for. Where do I find a 3/8" v-pulley that will go onto one?
