I bought a basketcase.  She's in pieces but I think (hope) they're all there.  I have a spare washer that fits on the shaft directly behind the worm gear.  Can any of you tell me if there should be a washer there?
BTW I just love this forum.  I'll probably join your group.


Thanks,
Jack

You need fiber washers. All the gears should have a fiber washers. You will also need a leather washer behind the blade. The leather washer is 3/4" ID 1" od.

What is the type number?  It will be on the motor badge.  The diagram that you have posted is a later model and may not be exactly like yours.

I think I have all the washers.  The leather one behind the blade looks to be in really good condition.  The others don't look fibrous but rather thin metal.  moreover there is a gear from the gearbox that doesn't appear to be metal but some kind of fiberglass or resin.

Hey Jack,
It is good form to replace all fiber washers when you have it apart. No sense in risking having to open it back up when the old washers break and the fan goes a knocking.
I buy this set. Has all the ones for Emerson shaft and oscillator parts. As well as for most rotors I've encountered. Some useless sizes, but I've found uses for some of them. Price is the best I've found.

Thanks Alex.  
I was thinking the same thing and found a sheet on this site that listed some washers from McMaster-Carr but these from Amazon may be a better deal.

Now I just need to determine which if any are missing and where they go  lol.

You're certainly welcome!

Generally, with iron gearboxes, you'll use two of the Amazon ones between the drive rod and case, then two in back. Two of the bigger ones on the big wheel shaft, and one between shaft and osc wheel. One on low cog end of drive set, and one or two on top. Then two on the back of the drive shaft the rotor runs on, and as many as you need to get end play to less than 1/8" when the end is screwed on. If oscillator rod is tight, remove one from between the housing and worm.
The Amazon set is superb and all of my fan run them. I have never found a need for anything else. If I need a thinner washer, I sand the ones in the kit down. Rare I need to though. Don't forget to pack the gearbox with green Lucas X-tra HD grease. The red tacky separates too much after a while. The green I have witnessed no separation.

Cool!  I may need to send some pics at this progresses.  I can only work on the project sporadically so it may be a while.  It's funny that I read about the Lucas extra heavy duty grease and the Lucas red sticky product and found that the red will separate so I placed an order for a pound of the extra HD.  I'm patting myself on the back right now for making the right decision.
How do you clean your parts so well?  Do you sandblast them?  I'm wanting to preserve the original Japanning.  It's not perfect but it's not too bad.  some parts like the oscillator adjustment knob (I guess that is what it is) has a thin layer of oxidized grease on them that resists soap.  I was thinking about using some rifle cleaning solvent or naptha to remove it.
