Sequoia Alt in 3FE?

[Red Beard]

I was looking into getting photomans adapter for the sequoia alternator for the 80 series, but noticed its for FZJ's only. Has anyone tried to fit a sequoia/tundra alternator in a FJ80/3FE?

I'm interested in this also.

There must be a way! Anyone with pics to compare the two alts? Even for a new unit from Toyotapartsales.com will cost $310 for a 130a, $332 for the 150a. Heck, that about the same as a "mean green" which may or not be mean.

There's always a way just depends on how determined you are and your budget. I have never heard of one but I'd be glad to see one done.

I am about 95% sure it could be wired up. I have no idea what the connector looks like on the 3FE but wiring alternators is relatively basic. One wire, usually coming from the ignition gives them initial power to excite them until they get up and running. A second wire is a "sense" wire that is connected in a 12 volt circuit so the voltage regulator can tell (sense) the voltage value and adjust. The third wire is just for the idiot light. Sequoia's have a fourth wire that goes to their computer but this wire is not needed if the alternator is going to be used on a different vehicle. Lastly, a large charging wire just goes from the alternator to battery positive so that one is easy.
Before I did this Sequoia adaption I had adapted a 100 amp Delco on the cruiser. It was not popular since it was not a Toyota part but it shows using different alternators will work. If you care to look, I did a thread on it years ago.
I do not have access to a 3FE to see what would be involved and seeing what could be worked out. Physically, it would be making sure the large case alternator would fit in there somewhere, get the pulleys to line up, and ideally using the same belts and adjusting system.
To answer your question 3FE alternator probably has 3 wires, the Sequoia has 4; but the one would not have to be used. It would be best to buy the Sequoia wiring connector and do the wiring using that connector. I hope this helps.

I'm going to get one and play around with it.

Looking forward to the outcome!

The wiring is not really a concern. The physical size/mounting of that guy in the stock location will be tricky. You will most likely need to move the smog pump up (or in my case the York) to keep it off the exhaust manifold.

Anything is possible given enough time and money. I happen to know of a 3FE sitting on an engine stand at a fabrication shop in Jersey waiting to go into an FJ40. Perhaps if we had a count of the 3FE folks here who would be interested it may be worth his time to investigate. He would need the alternator in question first.

Can anyone out there give me a list of donor vehicles (year/model) to start searching for one?
Is there a physical difference between the 130A and 150A units?
Does the V-Pulley from an 80A unit fit correctly on one of the newer units?

 

[rhyary]

The 80 pulley fits on the new alternators.
When I got mine it came with the serpentine pulley and I had to remove it and put on the new 80 pulley. fits great.

Is the 1FZ-FE alternator pulley the same as the 3F-E alternator pulley? The 3FE has 2 V grooves on the pulley, but all that really matters is the shank size.

I went to my local dealer today. They did not have a spare (good or bad) Sequoia Alt lying around. I forgot to ask if one can purchase the connector (4-pin). Down here we dont see many Sequoias (or any post 1998 Toyota SUVs) at the local junkyard. Not sure where to gather a connector other than a parking garage (which would be wrong of course)

I was told that the shank sizes for most Toyota alternators are the same by Jim Godwin on the 3FE list. Below is his message:

I think that the pulley shank diameter is the same for the 1FZ and 3FE, but my reasoning is not direct. The 2F alt has a pulley shank diameter of 17 mm, a 3FE pulley will fit on a 2F alt so the 3FE shank is 17 mm. Kinda of using the thread on MUD for this swap I installed a Tundra 130 amp alternator in place of the smog pump on a 2F and in doing so I purchased a pulley for a 1FZ alternator, and the inner diameter of the pulley was 17 mm,. So shank diameter 2F = 3FE = 1FZ. *disclaimer* I'm going by memory so I could be wrong.

As a caution there are two models of alternators out there that will work but one has a smaller shank diameter. I had one of these and had to mill a bushing to take up the slack between the shaft and the pulley. I have the numbers written down somewhere or you can find the part numbers on these alternators somewhere in one of the MUD threads.

I've been thinking on alternative alternators this since I replaced my alternator a month ago. My old 60 came with a Delco which definitely was rigged and worked fine. Back then I found a thread on the 60 forum that showed a one wire Delco alternator. The big wire, as big as a battery wire ran from the alternator to the positive connector on the battery.

So from jim's post it looks like you could just use the smog pump mount without a special bracket.

This was on a 2F. Don't know about a 3FE

 

[bhmmapping]

the mount looks the same. There are several of these alternators in junkyards around here according to car-part.com. I might have to pick one up and try it.

The alternator that I'm using is one I got at Grahams and I think it was only $70.

They had one listed for 75, there was one downtown for 85 and one up near Florence for 40. I have to go up there in a couple of weeks and will probably pick that one up. they certainly do seem to be readily available.

I took a look at the 3FE alternator mounting and I think that a Tundra/Sequoia alternator could be adapted without too much difficulty. The one glitch, but minor, that may crop up is using a double V pulley as a pulley with the same spacing as the 3FE pulley may not be available. In that case just go to a single belt pulley and source a smaller belt to run the smog pump.

 

[elprup87]

The belt is not an issue for those of us running without a smog pump anyways (or at least the smog pump hooked up).

On the setup with two alts, were they running at the same time?


Anyone heard of these guys? I ran across their page while browsing for an alt on craigslist in Dallas. $140 for 130amp before the core return.

I'm not following here. What do you mean by, "May not be available"? I'm under the impression that the OEM 3FE pulley will fit on the alternator shaft.

IMO, new belts would be needed for both the new alternator and the relocated smog pump.
