how to disassemble the motor housing plate of an old royal PA GEIER

[royalsuper]

Hello everyone ! I am trying to restore an old Royal vacuum cleaner dating from 1917-1918 the motor is in perfect condition it runs very fast and makes a lot of air on 110 volts no rust and the carbon brushes are OK ! I removed the 4 screws to remove the motor housing plate to be able to change the brass bearings of the motor because they make a lot of noise ! but I wonder how to remove the round plate from the engine without damaged or broken anything because I do not have original spare parts
any help will be appreciated . Romain

Romain,

What a super awesome find you have, this circa 1918 Royal upright cleaner! I do wish you the best of luck in restoring this.

If there are vent slots on the motor you may be able to tap the bearing plate GENTLY with a screwdriver thru the vent slot to get it to slide forward.

If there is a vent on the other side of the motor flange, then take a flat screw driver and pry up on each side of the bearing plate gently from the vent(s). If this doesn’t work and no other techniques work, I have a last ditch solution that usually works for these bearing plates. If you end up needing it, I’ll make a detailed post showing the process.

Upon looking at the picture closer I think the bearing plate separates from the motor housing on the back side of the plate.

Are you sure this is a model H? The bearing plate on the H fits into the round opening of the motor housing and is held with 3 screws along the edge of the bearing plate.

In the pictures it looks like the whole bearing plate has four bolts that would go thru to the field coil. It looks like if you take off the four nuts then GENTLY tap the edges of the plate from the back side it should come forward.

If it's 1917 or 1918 I believe it would be a model F

thank you all for your valuable advice !! I will try tomorrow to push the plate from the back with screwdrivers @bikerray you are right it's an F model ! Unfortunately, I can't find the specific instructions for the F model on the net.

If the bearings are making a lot of noise, when was the last time that anyone oiled the bearings? A couple of drops of a 20 to 30 weight oil might solve the noise problem.

the 2 cups of oil were completely dry! the vacuum cleaner comes from an old agricultural farm in the state of washington and I think has not been used for a very long time! maybe the owners have never used oil for lubrication, the bearing at the front must be changed because he growls a lot !

Hi Romain,

I'm afraid I'm not able to be of any help, as the bearing plate on your Royal looks different than any I've ever seen or worked on. The ones I have worked on are like what Ray described for the model H, with 3 screws close to the edge of the plate. And as he and Kieran both told you, be very careful in your efforts to remove the plate. Wishing you the best of luck with it.
Jeff

Thanks Jeff ! I found this photo on the net representing many pieces of 2 ROYAL model H vacuum cleaners (on the photo at the top right we can see that it must have been difficult to remove this famous plate from the motor ) https://ibb.co/xskPBsh
