Ambulance fan resto

tanhis · Posted: Wed Feb 05, 2014 9:46 am Post subject: Ambulance fan resto

So I started to disasseble my ambulance fans and got to the point where I need to remove the fan from the motor. I got the rear bullet part of the housing off but the fan part does not want to move from the motor.
I have now soaked it in the wd40 and removed the nut. I even tried little heat and small bearing puller but stopped before I bend the fan.

So how other people have been able to remove the fan from the motor.

And pic from the gallery for the reference what I need to remove.

Tanis, were you able to remove the fan from the motor?

Does the knob pull straight off the switch? I found a cover and switch and need to remove the switch/knob to do a little work on the cover.

Never had one apart and don't want to break the knob.

No I was not able to remove the fan from the motor whit out breaking it so I left it on as I got the motor spinning freely whitout removing the fan.

And the knob is held in place by the ring that mounts the switch to the body of the fan assembly.

I managed to get the switch bezel off; the procedure is in the Bently too.

I believe i am missing a spacer of some kind for the switch; It will not tighten up on the cover properly.

Anyone have a pics of the spacer?

Cool , thanks

Looks like that may be fairly easy to make if I can not find an og.

Yes, the right side small washers are 2 stacked together.
They slip over the knob and ride on top of it.

While the switch is apart and wires are off you might want to clean the wire terminals from the back as those normally are quite oxidated and connect badly.

I just had two switches apart last week, (one used and one NOS) and my NOS switch looks like the layout that Everett posted (I saw you from a distance at Kelley Park, Everett) and I can confirm that there are two smaller metal washers stacked on the top of the switch handle.

Also, I'm not sure about any current reproductions of the knob or the bakelite spacer ring, but many years ago someone out West had a go at reproducing the knobs in black. I bought one at a swap meet out there, and the casting wasn't totally finished, but the overall shape was pretty nice and very accurate.

Here is the repro black (un-finished) knob on the right, the NOS Ivory switch and knob on the left (sorry about the "soft" focus):

I bought one back then and just last week carefully wet-sanded the knob outer surfaces first with 600, and then 1000 grit wet/dry paper, and then used a tiny buffing wheel with plastic buffing compound on a Dremel tool to finish-buff it out. It turned out beautiful, I am very pleased with the results. The following shot is of the black knob after wet/dry sanding and before any final Dremel polishing. Note the knob has no red lens (yet):

The repro black knob had no colored lens in it, but I should be able to cut out and gently glue a red Eisenglass lens (like you use for speedo warning lights) into the hole. Since the rest of the knobs in my 1959 Double-Cab are black, it would be nice to have the Ambulance fan switch match too, although most switches on black-knob trucks seemed to have been ivory... The following shot is after the Dremel compound polishing and mounting it in my used switches:

As for the black spacer rings, I'll bet someone out there who is handy with plastic moulding, could easily reproduce that spacer ring. I'll bet that 50% of the rings on switches are at the very least cracked, and that many of us with switches are missing those spacer rings altogether. Hopefully some enterprising entrepreneur will make a nice little run of them and make a little profit helping us complete our used switches...

Bill, I can make the spacer. I just need a good one to copy.

Here is my fan that I restored in 2002. I made the spacer out of fiberglass poured into an applesauce container. (before I knew how to make molds and copy an original)

That black knob looks good; I was thinking the same thing on the fan switch knob matching the rest of my dash knobs.

The white fresh air-control box knob bugged me to death until it was replaced with a black one,

I would be in for a couple repo spacers and black knobs if someone makes them.

Can anyone clear up for me what switch knob style is original?

Seems to me that there are two basic ways the handle blends into the center post of the knob where the red light is. Smooth and what I'll call blocky.

In this thread above Everett shows a blended white switch in his April 8th post showing all the parts together. Bill shows a more blocky switch in his April 10th post with the white original and black repo. The blocky one also i shown in tanhis post as well.

Which is correct? I have two fan units here. One we have had for 40+ years that is smooth and another i just found with a broken blocky style handle.

Undertaking a restoration of a unit and would like to find out more.

Thank you to those who know more than me.

It took me a second to figure out what you meant.
The "smooth" knob I posted above is weird - that is the only one I have like that.

All of my ambulance fans and switches are the "blocky" style.

My Dove Blue one, for example:

Thanks Everett. I tried.... was I was able to link pictures...

I figured what you said was likely the case. Digging through a few Ambulance fan threads seem to indicate that. It seems most of the "new" replacement switches on the market are what i call smooth (blended) if they have the red lamp integrated.
