'New' Alternator mount?

[Coolerman]

This weekend I was finishing up stripping the tub in preparation for body work. I had a few minutes and decided to also start mocking up the Mini power steering stuff. I mounted the 2F alternator bracket and when I mounted my 1F alternator to it I could not get any adjustment from it as the body of the alternator was touching the hose from the thermo housing to the pump! I was like WTH! I looked at pics I found by searching and everyone else's seems to fit with plenty of room. Hmmmm...

So like any good Cruiser head I started playing around and came up with this 'new' alternator mounting method that appears to work perfectly and would allow something else to be mounted on top (AC or York compressor) with a custom bracket. This uses the standard 2F bracket just in a different way. Until I get a 2F non clutch water pump, plastic fan and spacer to match and a 76-up 2F 2 groove crank pulley (both wide groove!) I won't know if this will line up correctly.

Comments are needed! Oh and if you have any of those parts let me know...

Flip the alternator to the top of the bracket. It kinda "cradles" in the bracket.
The adjuster also pivots from the hole closer to the block.

I can't tell from your pic, but there should be an engine lifting hook between the alt bracket and the head.
IIRC

Can you see from my avatar?

Oh I know where it's 'supposed' to go, it just does not fit on top because it hits the bypass hose. I do not have the engine lift hook. Been looking for one though! I'll take a pic of the interference tonight then update the post.

Edit: Well DUH!!! The engine hook would space it out about a 1/4" allowing the body more clearance. Need to stop drinking on Sunday!

Taper off s-l-o-w-l-y...............don't do anything rash

I believe that mount was designed for something similar to what you have done... I just don't know how exactly the Toyota guys arranged it.
I believe the A/C compressor mounted in that position, or in the original alternator position.

I was going to say it just worked too well not to be stock. The place where I put the adjuster is beefier than the stock place so I know it will handle the load and there is a LOT of adjustment! I hope it lines up, that way later I can add another alternator!

 

[Degnol]

Does that interfere with your battery?

The alt. bracket is mounted flush with the head...the lifting hook would go on top of the alt. bracket, not behind it towards the head.

Good question. I will need to check that tonight! I have a dual battery tray from Man-a-Fre. I just looked at some pics I had and it looks like it should clear no problem.

Hmmm that is how it is mounted now and the alternator body does not clear the hose. I know I could cut about 1/2" from each end of the hose to gain a bit of clearance. Were there different adjuster brackets for the 2F? Maybe I have the short version?

Differnce F vs 2F alt

The 2F alternator is clocked differently from 1F. The F alt won't work w/ the 2F adjuster because the adjust bolt is clocked over to the outside. That pulls the alternator too far in. You can either use the F alternator brackets on the 2F, or get a 2F alternator.

If you are really fond of your current F alternator, you could just change the front casting to a 2F casting, w/ the adjuster ear in the correct spot.

HTH.

Well, I'm cornfused........the pic in my avatar is of my '74 F with the F alternator that was previously mounted on the driver's side, low. I have my engine lifting hook next to the head(I think) and it worked just fine.
If you can see the ears on the alternator in my pic, they appear to be the same as Coolerman's

Just to clarify, you're saying I can use the F alternator with the 2F bracket on a F engine, IF I use the F adjusting bracket? I can do that though I was planning to upgrade to a 2F alternator later anyway...

Ed, you managed to make it work, in spite of not really fitting.
It seems you have a gift for that.

If the bypass hose is short, and if the belt is just the right length, the F alternator can be slid over 'til it hits the hose, belt slips on, then alternator is slid out & tensioned without running out of adjuster slot.

No, I am saying the F alternator in the F mounting brackets on the side of a 2F block.

OR a 2F alternator on a 2F bracket on the topside of a F engine equipped w/ the accessory bolt holes on the cyl. head.

OK got it Jim!

I'm home now and placed the battery tray mounting pedastal and stock tray in position and the alternator just barely enters the battery space. So when I get some other parts I can test this out. I'll post a pic later...

Ok as you can see there is a bit of interference with the battery but not enough to worry about. My dual tray is in the de-rust tank. As it is much longer and I plan to run Optima type batteries, this is not an issue. The only thing that remains to be seen is do the pulleys line up? I'll let you know.

F vs 2F alt pics

This thread is useless without pics....

So here's a pic of a 2F alternator, in it's bracket, and an F alternator for comparison.

 

[Coolerman]

Just to see if the F alternator mounted in the 2F bracket would fit the way Degnol did it I mounted mine the same way. I had to space the adjuster bracket out with washers (well they were big ones at least! ) but would use a large cut spacer if I did it for real.

It does indeed fit and as Jim C pointed out the belt size will be a bit harder to determine as there is not a lot of adjustment. I could gain a bit by trimming the bypass hose.

HTH's someone. You can keep your F alt which means you can keep your stock amp meter.

Thanks Jim, now I see what you meant by clocked differently and how it could be remedied by swapping front castings.
