Woodmizer Alternator
« on: August 09, 2020, 01:32:00 PM »
I'm on my way to investigate this, but I figured I'd seek some for some tips here while I do so. I have a 97 LT40 Super, Diesel if it matters. I'm pretty sure my alternator just gave up the ghost, and I'm pretty sure it's an off the shelf Delco unit. I would just order it from WM but their parts have been slow the last few times I've ordered, and I kinda need it now. I know I've seen some of you in the same predicament before, did you find one at the auto parts store?

I don't own a Wood Mizer, but if you take it to a reputable parts store, they can tell you all about it and should be able to provide a replacement that is acceptable.

There are Lot fewer models of alternators (and starters) than there are makes, models, and sizes of motors they go on.

I have gone the "other" route before when in a pinch, but I don't recommend it.  I would order the correct alternator from Wood-Mizer.

Agree, Give them a call tomorrow see when they can send it. Not everything is delayed. If it is, maybe they can tell you an equivalent. Although I think youíll find that thereís no generic  swap.

If you know a good motor repair shop those places can be good and pretty fast.

10Si and 12Si are your most common GM alternators.  

Before you buy anything have you verified with key on engine off that you have 12v going in to the field wire on the regulator or case lug?  If theres a charge light in that circuit the bulb MUST work as it is in series.  No bulb, no field excitation voltage.  


If you have 12v to the field then youll feel magnetism around the case when its running.

My LT70 had 2 alternators. A small one on the Yanmar engine and a high output that Wood-Mizer put on. I fried a bunch over the years and tried to keep a rebuilt one on hand because a bunch of guys doing busy work gets expensive. I have found replacements at the parts house and also had them rebuilt while I waited. The factory units seemed to hold up longer and yes they were quite a bit higher in cost. I am thinking the larger high output from WM was close to $500 for that mill a few years back.

I had my original 15 year old alternator rebuilt which did not last, but this new replacement 140 amp alternator is over 4 years old and is going strong.  It cost $188.38.

Well, what I learned is that my alternator is an AC Delco CS130D, 105 amp. Now, I can't guarantee that the internals are the same, but my mill is currently working great. However, my 01 Chevy Duramax isn't going anywhere until I get done sawing😁 Same alternator😊

Same price now, or $30 less without the pulley on it. From the WM parts finder for 2001 lt40 super Kubota 42hp just now.

Mostly what I was looking for was something I could get at a parts store, today, as I had an order I needed to fill. The solution ended up being 20' from my mill 😊





The main drawback here is I have to put it back on my truck before I can go to work in the morning😂

Hope it works. Itís a 140A alternator on your mill, hydraulics run  100A or more out of your battery when  active. And starting the diesel too.

Thanks 47, sometimes you make do or do without, right?😁
Terrific, it's 105 amp stamped right on the alternator. WM parts page says 140 amp upgrade available.

Major changes/upgrades were made to the LT40's in 1997.  The "Super" has 2 hydraulic pumps and I would not replace with anything other than the 140 amp.

That's what I was talking about.  There aren't that many different alternators.
I'm also driving an '01 Duramax, that I bought new in Nov. '00.  The first alternator lasted 115,000 miles.  The NAPA replacement, that I picked up on my way home, without turning the motor off, the day the gauge said it had quit charging, has 241,000 miles on it, and I forget how many years.
When you have to get another one for the truck, check the pulley diameter.  There are three different pulley sizes for those trucks, and either 105, or 140 amps.  Some of them had two 105's in them.  If yours has one alternator, like mine, you'll see the mount for the second one on the other side.

Terrific, no need to apologize- I suspect your several year newer mill was supplied with the 140 amp upgrade.
