A neighbor picked up a civic fan that bolted right-in on his Datsun 240z, and I was wondering If anyone has experimented w/something to replace our tired fj40 fans...

my heater/blower fan only has one speed...slow,

Here is a Napa part# 655-1747
I think this is for a Chysler product.
The hardest part about a replacment motor is the shaft length and diemeter that will match up to your squirl cage. I bought this for my '68 FJ-40; I had to modify the mounting flange on the motor. You'll be impressed if you decide to go this rout: Kept my windows defosted even at -50 degrees F.
 
Climate conditions in Alaska make this a definite candidate...
Do you remember if you continued to utilize the in-line resistor?

Thanks you for the info,
manny
 
How about a motor for the rear heater. Mine is frozen solid.
 
All I did to hook this up was cut the two wires after the resistor and solder it up to the new motor. So I could still retain the two speed switch.
 
fan?

I just changed my fan motor to the one suggested. Since the shaft of the new motor is not threaded I drilled it and used a cotter pin to secure the orginal toy squirrel cage fan. It causes a wobble and viberation noise.

Did you use a different fan that attached to the Napa fan motor?

Thank you
 
I used the stock cage which is not threaded on my '68; just used the tight fitting sleave that was on the original squirrel cage. If there was nothing securing the cage on the original motor then I would say your OK. I ran mine for a few years that I owned it and had no problems; just using the sleave as the only securing devise.
Hope this helps
 
heater upgrade completed

Good day,
Thanks goes out to Alaska Wheeler for the hookup on the Napa Part number.
On my 76 FJ the "squirrel wheel fan" input shaft hole was larger in diameter than the Napa Fan shaft making a press fit undoable. I drilled a hole through the shaft and another through the shaft and wheel and inserted codder pins in both. It took both holes and pins to hold the fan securely.

I used 1/4 aluminum(sp?) It had a veneer of stainless steel as it came from an industrial stove top (salvage yard $2.00), for the bracket and will be getting a nice new fancy Pertronix coil to put up there very soon.

I replaced the rubber gromets from the old heater fan bracket with "windsheild wiper" groments from Schucks. They were in the HELP section and work great if you cut them in half.

Will update with how it works this winter.

I used Rustolem plastic paint and primer for the blower shroud and for the internal ducts. Even though I pre sanded and prepped with Alcohol had some spidering of the paint which I did not like. The motor was painted and primed with regular Rustolem flat black no problems.

I tried to post pics but we'll see if it works
 
pics try #2 and some additonal info

pics

mounted the restistor behind the motor for looks. The first pic is the Napa motor. It comes attached to a large plate that is full of lumps. I cut most of it off and then cut the remaining lumps down the middle and hammered them flat before attaching to my new shiny plate.
My first attempt I tried to modify and use the Napa's orginal bracket but it looked to "backyard fab" when it was done. ---just because you are ghetto doesn't mean you have to be ghetto.

Manny, I found this info in an old thread and stashed it away for the next time the question came up; don't know if it will answer your problem, but if you try it, give me a call and let me know so I can spread the info as reliable:

resistor, 1 (one) ohm @ 50watts, Allied Electronics part #895-1200 $3.52

:)
 
This is in the FAQ....hopefully it will be around for a while :)


Thanks Mark!
 
I installed a Ford Escort motor/squirrel cage unit into my 67 FJ40's stock heater motor housing. That was about 8 to 10 years ago so my memory is a little fuzzy on the details, but I believe the new motor was from a 88-89 Ford Escort. I'm not 100% sure on the years I listed, it could be from the early 90's as well.
I originally got the motor from my Dad when he worked at a Ford dealer since he was tired of seeing it collect dust. It was a "take-off" from a Escort that received a dealer A/C install.
As far as I can remember it went in fairly easy because the squirrel cage was just slightly smaller in diameter than the LC's. I think I drilled new holes for the mounting screws and that was about it.
Here's some pics that might help identify what year this thing is from.
It works like gangbusters too. About twice as good as my tired stock unit.

I had to put this one back up because of the winter time is here. I just got off the phone with a Ford stealership and they said the motor runs around $170 and the squirrel cage was discontinued in '97. Junk yards here I go.
 
Just got back, one from a 1980 Toy mini-truck works, but get the gasket and stack it with the original gasket, the hieght of the mini-truck assembly is about an 1/8" too high.

You can get the mini-truck assy at most major auto parts stores also.

As to the above, the escort unit from 91-95 is too big.

:beer:
 
What perfect timing. I need to upgrade my fan motor too. I'm tired of carrying a squeegee to clear the fogged up windows. I was going through my old Ford motors to find a fit, but this saves a lot of time.
 
I can't believe I missed these updates!
Motor is still slow, but not for long...this forum ROCKS :D
thanks,
manny
 
if you have an older criuser updating with a newer plastic fan make a big difference and it bolts in if you keep the metal housing then you have to make the hole a little bigger have 79 heater motors in my 4 older toys 65 to 70 and they all stay warm good luck
