Is anyone familiar w/a fan motor upgrade on our trucks?

mr_manny · 10-05-05, 06:39 AM

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,

Manny
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.

mr_manny · 10-05-05, 02:49 PM

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

890man · 10-05-05, 02:53 PM

How about a motor for the rear heater. Mine is frozen solid.

AlaskanWheeler · 10-05-05, 05:16 PM

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.

Dietoy · 10-15-05, 11:42 AM

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

AlaskanWheeler · 10-15-05, 04:36 PM

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

Dietoy · 11-02-05, 11:04 AM

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

Dietoy · 11-02-05, 11:24 AM

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.

missipboy · 11-02-05, 03:08 PM

that's some nice nonghetto looking work, dietoy.

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

Poser · 11-02-05, 10:32 PM

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.

mdjohnsen · 11-16-06, 06:19 AM

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.

fussy_cruiser · 11-19-06, 11:51 AM

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.

Brian in Oregon · 11-19-06, 02:42 PM

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.

mr_manny · 12-13-06, 11:42 AM

I can't believe I missed these updates!
Motor is still slow, but not for long...this forum ROCKS

thanks,

shelfboy1 · 12-13-06, 12:57 PM

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

MoCoNative · 04-05-07, 01:52 PM

More checking would have to be done on this, but as I recall the fan blower motor in my FJ-60, and the one in my 73 FJ-40 were almost identical, in fact I was quite surprised by how similar they were. The flange pattern is the same also I think.

I'm looking at NAPA online right now, a new unit for the 60 is only $51.00, a new unit for a 1980 Toyota pickup is $81.00. I'd get the one for the 60 I bet it will bolt right up.

The 60 series seems to push a little more air than the 40 blower also in stock applications.

Something to think about.

mr_manny · 04-05-07, 02:56 PM

picked up a Ford Escort motor over the WE...wish me luck

mr_manny · 04-13-07, 03:48 PM

Finally got around to installing my ford (cough, cough) escort fan

Pickup an blower fan motor from a 90+ escort (regularly available in your local donor yard)
Don't look under the hood, check under the glove-compartment.

Remove the hamster-cage from the fan motor and use it as a guide to trace what needs to be removed from your blower housing.
(I used a jig-saw and a mini-grinder)

Re-attache the cage, and insert into the housing.
Take your time and rotate the blower flange until you find a spot that will does not interfere w/previous attachment bolts.
Drill 4 or 5 small holes for some sheet-metal screws and install.

I need to pickup some plastic spacers, and some weather-strip to complete...but it's pretty much done.

Thanks again B2BER

So how did this mod work out for you, would you recommend it?? Any hitches...

Thanks

Brian in Oregon · 05-28-07, 01:37 PM

So which moves more air - the Escort fan or the NAPA 655-1747 fan?

Brian in Oregon · 05-28-07, 01:49 PM

Hmmm, I went to http://www.napaonline.com and tried to look up a 655-1747 fan. Nothing came up under that part number. A search for "blower motor" on their website shows these to be in the part number range of CCC-937XXX. Further descriptions are by physical fan size, shaft size and length, voltage and rotation (CW or CCW).

shelfboy1 · 05-28-07, 01:56 PM

i dont know how many there are laying around but the stock late model heater fan bolts in. if you have the metal housing you will need to trim a bit or the whole assembly from a 79 or so will bolt in . just need to hook up the wires .there is only about a 4x6 opening for incoming air. a fan can only put out what it can take in so you may have to open the vent a little for more air with a higher out put motor . for a simple test run the motor with the vent closed then open it if the motor speeds up then its starved for air good luck

mr_manny · 05-29-07, 09:53 AM

I don't have any experience w/the napa fan, but from reading the thread...if it works in Alaska, I'd say It works

The biggest difference between the napa/ford fans is the necessary trimming of your fan housing (w/ford).

what's the condition of your current fan? mine was tired...which is available for a week or so (before it's tossed).
