B series Alternator Upgrade...

[nostep]

I was looking at adding an alternator to my B6100. The Kubota supplied Denso would work well. It is very close to fitting in place of the idler. Problem is the side panel and possibly a bit of the hood would have to be bumped out (cut/welded/etc). Only needs about an inch more :-( So for now, I'm going to stick to the whole 7 Amps or so from the Dynamo :-(

I figured there would have to be some mods to the side panel. Will wait and see what the other replies will be. Thanks

WOW, is that all the dynamo puts out for power?
Wonder what Kubota was thinking when they put this thing on these tractors.

I looked at the 7510 before I bought my 2350, and I remember that dynamo under the hood, and wondered then what were they thinking.

The small gray dynamo, that comes on most of these tractors, is rated at 15 amps. To get this, the engine would need to be above idle speed.

The 1970's era b5100/6100/7100's are rated at 90 watts.... which is 7.5 amps at 12vdc.... 30+ years ago when new. You can run the headlights and the flashers and that's about it unless you want to have to put it on a battery charger every time I would like to install better headlights/worklights so I may have to study this a bit

There is not much to run on a diesel. Everything, except the glowplugs, headlights, hazzards, is mechanical. The lights on these tractors are pretty low power. No need for big electricity, to run a small set of lights. Unless you add more...

What about a small alternator from a compact Chevy? Using a 1-wire alternator from a Chevy/GM has long been a trick on old Jeeps, that had wimpy alternators.

Might be worth a trip to a "pick-n-pull" wrecker yard to poke around a bit...

I know space is tight; my B8200 has that tiny little dyno on it too(although book says alternator...???)

As I understand it, my B3030 puts out 14.5 amps via the dyno. What other advantages, besides more lights, can there be by switching to the 40 amp alternator? Will exisitng systems work better, for example? etc. thnx

NOPE, Its all about the added Amps = More power available. Average 55 watt lamp = 6 amps. I have 2 forward and 2 rear...= 24 amps. = slowly draining battery if the dyno was left in place...= eventually dead battery while working, as well as the extra strain of completely draining and charging the battery..

Not to mention the strobe lamp.= 1 amp, Future cab heater, 10 amps...

12 volt power point for running what ever. air compressor...radio...coffee mug heater.....etc..

I like to have the extra power...

My botas lit up like a christmas tree at night .TWO forward 55s to rear 55s,strobe light on top, heater fan,circulating fan,a row of led toggle switches,tractor flashersetc etc.
no way could even come close to this with the dyno.WILL existing system work better?It will if your drawing too much,lights will be dimmer once you draw the battery down below normal voltage.Iknow this because i use to run these lights with the dyno,then let the tractor run to charge it back up.Lights werent as bright at 10-11 volts,as they are with 14
