D6 9u Altanator Conversion

here is what i'm running so have a good laugh. 5 years ago i got the idea from the old BB but i use the same belt i use on my IH cats so everything is the same. started off with an aluminum pulley and after about one a year i gave up and found steel pulleys work the best. but finding a big steel pulley in the great white north is getting harder and hard so this is what came when i told the guy over the phone. i guess when you are 1200 kms away big is not that big, LOL.

This will probably take a couple of posts but at least it will be a start.

As usual, what appears to be a simple task turns out to have several variables.
There are lots of options to mounting alternators. Some things to be considered are:
1. Use the gear drive mounting.....requires the speed increase gear housing such as used on the higher output and 24V generators.

2. If going the belt drive route consider a double belt as there is not much wrap around the alternator pulley.

3. The belt drive option also gives the opportunity to machine new pulleys and get rid of the Cat adjustable pulley arrangement and use the alternator as a take up......don't forget to build in the attachment flange feature to the crank pulley if your running the #44 or #46 pump....or other front mount attachments.

4. If your going to be running an attachment such as AC you will want to consider driving the alternator and compressor through a modified gear drive arrangement.

There are several type alternator set ups offered out there...the good ones retain the cooling fan, have a flex coupling drive and retain the slotted flange for gear mesh adjustment. The junk ones have no fan, no flex coupling, may or may not have gear mesh adjustment and what looks like hand torch fabricated adapter plates and poor fit.

The two main sources of quality ready to mount gear drive alternators that I know of are the ones produced by:

American International Manufacturing
1230 Fortna Ave
Woodland, Ca.
916-666-2446
This unit uses a machined cast iron adapter housing, lovjoy coupling and usually has a 40 amp Motorola or Delco 10SI marine type alternator.

CME Arma Inc.
4500 NW 36th Ave.
Miami, Fl
305-633-1524
This unit uses a machined aluminum housing and I've only seen them with the Motorola alternator.

These units are not cheap.....around $400 but would certainly compete with the price of a Caterpillar alternator. I have no idea if individual components could be purchased.

And of course...some pictures.

Also check the Electrical section of the starter conversion stuff at:

I purchased a "conversion kit" from Assocated Tractor Service in Stockton CA about a dozen years ago. The kit included the alternator and the bracket that attached directly to the engine; a very "clean" look. I don't recall the cost but it has worked great for many years.

Hi Delta KJ,
I suspect that is one of the American International Manufacturing units as they have been servicing the west coast for many years.

Hopefully a photograph of my alternator "kit" is attached. As you can see, the alternator faces the rear of the tractor.

that is a nice conversion compared to mine. like the steel pulley.

how much was that kit???

Don't know anyone supplying that version as a kit.
