Possible bolt in 140-145a alternator

[toyotaspeed90]

The alternator in my 93 have way.

I read about the Sequoia 150a upgrade available and needing an electrical connector and the adjuster adapter.

There is a company nearby that specializes in batteries, starters, and alternators... basically nothing else.

10 years ago or so I worked in parts and it was normal to find bigger alternators or to have to check clocking....

I asked if there was a possibility of something similar in size/clocking/wiring, but higher amperage. Said they would call back.

Talked to them yesterday, but unfortunately wasn't able to make it in. They found a possibility, with the only thing not 100% known was if the pulley would fit.

Went in today - however their test shop stated the unit didn't meet their standards and won't that unit. I did, however, get my hands on the unit. the location of the main power and plugs were on the back in a different location, but the same otherwise. The bolt hole isn't threaded, so a through bolt and nut would be needed on the adjuster. The housing was larger but otherwise physically the same.

They did state it's a different/newer technology that provides far more amperage at lower RPM as well. Said if pushing hard at low RPM it will provide amperage, but may want to rev at times to cool it down.

OEM Whatcomy Electric is the company.

If it works out, I will post the car it comes from...

I want to read this as exciting news, but I've had a couple beers. As best as I can read the post though, it says it might be news.

...so "not yet" on the bolt in high amperage alternator?

At least you're honest - LOL. Waiting for the results as well...

Keeping you guys up to date as much as I am up to date.

The shop was apparently excited to have found such a good physical match once they had their hands on my alternator. They have fixed the unit they have and swapped on a new (verified it's identical to my old) dual belt pulley.

I wish I had thought to get photos, but I had my 3 YO with me who kept inspecting all of the flashlights and battery posts all over the shop.

I will hopefully be picking up the alternator this evening, will get some photos. When I had my hands on it, short of a micrometer, everything looked identical from a clocking/bolt in affair.

From my understanding it isn't just a normal alternator that makes more power at higher rpms....

I have priced some of these alternators elsewhere at a lower price (and assume used would be even far cheaper) but the price I've been given is $290 after core. Their prices are usually higher (a rebuilt 80 Alt is $190) but they don't do a 'replace what's bad' type rebuild either.

Some stock photos for comparison..... the alternator in question vs the 80 alternator.

I will give details once it's in the truck....

Very cool. Was considering adding a high rated alternator given all the lights I'm adding. Would love to find a bolt on option.

 

[nuclearlemon]

so i'm confused...is this an alternator from another vehicle that works, or an alternator we have to get from your oem whatacally electrical company?

 

[McDowra]

Interested.....

You could add threads to the hole. Could be as simple as a Helicoil, or Keensert.
Looks pretty promising so far.

Yes if this is a bolt on replacement from another high quality manufacturer this could be a great find! I was just mentioning to someone that I anticipated needing a higher output alternator for my LX.

be careful if this is one of those companies that is "beefing up" your stock alternator. I have seen these type of beefed up alt's go bad many times. From my knowledge they beef up the windings, etc to boost output BUT don't do anything to the regulator and when that fails.......POOF. I had one go bad on my 80 and blow the fusible link. Only time I have ever had to tow it home. I am running the sequoia setup now.

 

[toyotaspeed90]

I have it in house now and had them make up a new high quality positive lead.

I threw their name out because they are the ones who figured it out. The alternator is a stock unit for some newer cars. It is an ND unit.

There are several choices, but for various 2003-2004 Jaguar models with a 140a unit.

They explained something about the square/separated internal coils and provided a test sheet... I'll have to refer to it later, but something in the realm of 70 amps at 600-700 engine rpm.

I could see my old alternator in the parts bin. The case itself is around 3/4-1" in diameter larger. I'll check fitment tomorrow.

Did a little digging on Rockauto. The alternator in question is 130A, from a 2004 XJ8 w/ 4.2L V8. REMY 12580. $88.79 + $70.00 Core = $158.79

 

[Rivman1243]

The alternator's I see on semi's all have square wire in the field windings so they can pack more wire in the same area-thus higher output out of the same size

There are 130 and 140a units, less of the 140a units. I have no idea on size/clocking/connectors on the 130a units.

So.... have an update.

It is not a "direct" bolt in. At least in my configuration.

The alternator is in (must remove lower bracket to squeeze in). The belts are on. The lower bracket I was able to loosely bolt to the alternator and engine, but there is some minor interference since the casing is larger on the new alternator. Literally bolts are "in" but the lower bolt on the slider bracket is really unhappy and the bracket is about 1/8" from fitting against the engine.

This may be due to the belts I have. Before I had the belts on the bracket did fit but sliding downwards was limited and I couldn't get the belts on.

My plan is to make some minor grinds on the stock bracket and maybe just slightly enlarge the lower bolt hole.

1/2" longer belts might make it work, but I can't say from experience.

nice!

 

[toyotaspeed90]

The adjuster bolt is a bit close to the belts for comfort, but it's bolted in with tightened belts.

I think grinding along the top/backside of the lower bracket would be needed with longer belts, but can't say for sure.

Attached are the before and after. Enlarged the lower bolt hole, slightly, and the grinding along the top/back.

 

[toyotaspeed90]

I lied, once I actually tightened the adjuster bolts, no clearance issues.

Now I'll have to unwrap the stock main lead and run the new.

So in the end....true bolt-in? You used a new pulley, but could just use the stock pulley?
