Need help on this power nozzle?

[vacfan6384]

I purchased this power nozzle and the motor is bad I know I should post this in the market place but due to the rarity of this nozzle just wondered if anyone on here who ownes a vac shop can look and see if they have this motor I would love to replace the motor in my Royal pn to get it working again. The part number is 3159700000 and the model of this nozzle is a model 597. Any help would be appreciated as the original motor works but has a bad bearing making it arc really bad and don’t want to burn up the motor thats in the nozzle now.

U

Look and see how many amps your power nozzle is. Then go on ebay find a motor with the same amperage.
Open up the power nozzle and make sure the motors are similar.

Thanks for the advice

Thanks for the advice due to the rarity this power nozzle has a cast aluminum motor that has a bracket mount attached to it so I need to find the extact same motor someday to replace the one in it with the bad bearing it does not take a regular pn motor the motor is kinda unusual and unique for this model sadly.

Check

Ametek lamb. If you call them with model number watts amp etc they make every motor for everything.
Do you have pics I've never seen a cast aluminum power nozzle motor.

Royal nozzle

This may be same motor as Eureka and other power nozzles of this era.May make it easier to find.Others will know more if brackets can be switched.

Here is the motor

Sam, that looks like a ordinary Eureka powerhead motor with a metal bracket held on by 2 screws to fit the Royal. Take it out and take the entire motor assembly to a vac shop, they will be able to match it up for sure and get you a working replacement.

that's the same power nozzle motor airway used in thier rugmaster pn's from the 70's. its not a commonly used lamb motor and is 100% serviceable sam. you can reseat the carbons on this easily and keep the motor that's in there. even the bearings are 100% serviceable. that pn motor is fixable. contact me if you need help.

 

[vacfan6384]

Thanks for all the suggestions

Will I may need your help as the motor is arcing badly and the lady at my local vac shop said she cleaned the contacts and it is still arcing wonder if the bearing or bearings just need machine oil if they are brass

Carbon

Brushes could be bad.

 

[bnsd60m9200]

bearings have nothing to do with carbon arc. those are two separate things. unless the belt is too small pulling the motor to tight pushing the carbons out of plane, THAT can cause arcing. not a bearing.

Take off the four screws holding the motor. I have a feeling it's a bracket setup like what is shown below. If that's the case, you should be able to replace it with the standard Lamb/G.S. Motor that was in MANY different brands of power nozzle throughout the years. You need to make sure the shaft length isn't too long or too short though. The two holes at the top MUST be able to accept screws as well.

Here is the motor

I have tried and tried and cannot it it apart

There is two small screws in the bottom side on the last photo that will not budge to get it apart and I even bought a new motor but sadley the shaft is to short and not as long as the original.

 

[lesinutah]

Put

A lock nut screw on, coupler lockout screw and a piece of all thread( basically a bolt without bolt head(. This will make the shaft long enough for you.
I've literally seen 2 or 3 power nozzles exactly like yours on ebay the last 2 days.

Frankenmotor?

I reply: This is just a wild idea—and almost completely devoid of factual knowledge, since I've never owned or even worked on a Royal power nozzle— but I wonder if it's possible to take parts from your old motor and this new one to build a 'frankenmotor' that would work for your needs. I did this a couple of years ago when I needed to replace the motor in an Electrolux PN4A that was completely frozen up. I got a newer used motor cheap off of eBay that I thought would work, but it wouldn't quite fit the PN4, as the mounting holes were just enough off that nothing else would line up and fit properly. As I examined the two motors, I realized the front half of the casing was different on the replacement motor, but the back halves were identical, so I swapped front half of the old, frozen motor onto it, and it worked perfectly. Doing that was so far out of my comfort zone at the time that I was actually a little scared when I went to turn it on after I got everything put back together. You can imagine my delight when the thing fired up instantly and ran smoothly and quietly, just like it should.

Edgar - Good idea. Unfortunately a frankenmotor would not work for Sam's situation. Since the belt pulley is longer on the Ametek motor in the Royal powerhead, it would require using the armature inside the motor in the new generic Ametek motor in it's place. Problem is, by the time those motors are burned out, so is the armature itself, and it would cost a small fortune to take it to a small motor shop and have the armature rewound and new bearings put on. And, that's IF the armature will fit in with the field coil and plastic housing on the new motor.

Sam - Go to the dollar store & buy a cheap long screwdriver, and make sure it is made of chrome vanadium and that the metal pole is smooth and chromed. Ask your local vac shop for 2 mounting screws for the mounting plate from the old motor. Then find a local welder in your area, and take both motors to him. He will be able to get the motor bracket off the old motor by drilling the screws out. Then, to lengthen the belt pulley on the new motor and make it work in the Royal, all he has to do is cut off the screwdriver handle, cut off the bit on the end, weld it onto the belt pulley, cut to length, and then smooth out the end.

I have had to custom make screwdrivers before by having a welder weld on a bit onto a screwdriver when you have a screwdriver that is next to impossible to find any other way, so it can be done. Yes it will be a lot of work, but it will be 100% worth it because you will have a motor that will last. Will's suggestion to rebuild the motor is just not practical - will be VERY EXPENSIVE, and who knows how much more life the motor would have after it's rebuilt, plus who even knows if replacement carbon brushes are available for a motor that old, which would be a MUST if you were to even consider doing that. Customizing a new motor to work for the powerhead will be a much more practical, longer lasting solution. Good luck.

Um

Practical. Welding will not spin the screw straight.
I'm Tfsching a pic of all thread and coupler.
You put a nut on each side of the coupler and cut off the length needed.
The joint on the weld if put any under pressure it'll snap.
