B3030 Alternator Upgrade

David_Kb7uns · Dec 19, 2006

If it is the same as the BX2230 kit, pretty sure the alternator has internal regulator. If you look at the schematic for the dynamo circuit, it puts out AC to the regulator where it has a full wave bridge split in to 2 circuits one for charging and the other for the lights(so the lights run off -12vdc). When you remove this small regulator/rectifier unit you only need the jumpers and a couple wires to the alternator and that is it.

I think the worst part is drilling out the engine casting for the larger alternator bolt. It looks like there is a bushing in there, but I could not drive it out so I drilled it out. BTW, I think the reason the six wire connector only uses two wires is because on the dynamo the connection is to a regulator/rectifier and on the alternator the regulator is in the alternator. The only connection to the tractor at that six wire plug is to the idiot light and probably a ground or switched power. Someone with a schematic could confirm.

I would like to get the alternator upgrade. So drilling is required? That would make me a little nervous too. I havent heard of anyone else talk about drilling.

I did not have to do any drilling. The parts in the kit allowed me to utilize the original hole for the lower alternator bolt. It took me a couple of minutes to figure it out though. I used the smaller of the kit's 2 bolts, the supplied spacer to line up the v-belt, and a sleeve to go into the original hole in the block to accomodate the smaller diameter bolt. All that stuff is held in place with a washer, lock washer, and nut.

Although I forgot to mention it in my origianl posts, you need to remove the original oil dipstick housing. Just unbolt it and wiggle it, and pull it out - its held in by an O-ring. The new dip stick goes directly into the hole where the original dip stick housing went into the block. Good luck doing yours.

Re the dipstick: I tweaked the bends in the original dipstick tube so that it clears the alternator, that way I can use the longer original dipstick and not have to remove the side panel to check the oil level.

I learned that from a previous post here on TBN.

Thanks. I do look forward to seeing in the dark, and I hadn't thought of installing a stero, but now I think I will. (That outta thrill the neighbors as I listen to the Stones, AC/DC, Lead Zepplin, and REO Speedwagon.)
