With a lot of steps! First you make sure to un-plug the machine and turn it over onto it's side or completely over. You un-snap the belt cover and put it aside. Make surer you know where you put it! You then fit the hose adapter onto the fan opening making sure you fit it in right! You then turn the machine back over on it's wheels and it's ready to go! But! It's cumbersome as heck to use!

Thank you admin for pic of the day.
I have a 913. I just got a 913 and waiting for glue to dry on bag bellows I added and put a longer tube with a Kirby type f bag adaptor.
If anyone is reading this the rear motor bearing are on a plate riveted to body. I have a (I'm going to butcher tool name) blind pilot bearing puller. Do I use this to pull bearings or are they not meant to be removed and there is e technique to fix bearings. I know there is an adapter someone has to grease them but I need to get access to bearings as they are seized and I have to clean lubricate and reseal bearings.
Does anyone know when these were first made.

In order to get the bearing out, you must first remove the rivets. Many Hoovers (Convertible, Concept, Elite, and apparently even the 913) have bearings held in by plates which are riveted to the housing, and to replace them, I always carefully drill out the rivets. Once the rivets are out, the bearing should just slide out easily. No need for a puller. Then, I replace the rivets with the same size blind rivets. You can get a pack of them and the installer tool for very cheap from Harbor Freight. I think mine was like $6 total. It's a good idea to use washers on the back side of the rivets to keep them from pulling straight through the steel bearing retainer plate when you install them (speaking from experience).

While you have the bearing out, you might as well replace it rather than just clean/grease since this process I have outlined isn't exactly trivial. If you aren't using original Hoover bearings, I highly recommend you make sure that your replacements are C3 grade and EM (Electric Motor) quality bearings, which are suitable for high speed, high temperature use like in a vacuum cleaner motor. The wrong grade of bearing, even if it's the right size, can go bad really quickly (again, speaking from experience, lol).

If you clean/regrease, I recommend CRC Contact Cleaner for the cleaner and Mobil 1 Polyrex EM for the grease. The cleaner can be found at Home Depot and the grease grease is cheap on Amazon and is intended for high speed, high temp applications. In fact, many of the C3/EM bearings come from the factory with this grease already in them.

If you use your blind bearing puller on the bearing without first removing the rivets, you will likely destroy the bearing retainer plate.

Hey guys!
Thank you all for HIJACKING this posting! What was the topic Les? Oh! It was attaching the hose to the machine!! Not about your bearing questions!
Be respectful of other posters and their questions! Greg Bushman

Greg some one answered your question.
I didn't think people like you that get bothered by multiple threads on same subject. Hence the reason I posted in thread. I waited until you got your question answered I even kept it in the same thread. I put your feelings into thought before posting.
Greg sit down and just sit. This is a vacuum board. You can Google multiple places how to put on the adapter. The adaptor is the same for Hoover and eureka and it's been out over 65 years. Changing the bearing is not in the Google or any archives.
Mr Bushman a little manners and ettiqute are needed. If you don't want replys or comments on a vacuum cleaner web site maybe you should not post in one.
So trying to be nice was my intention but you making much Ado about nothing is not my doing. If you have a bad day or bad attitude doesn't give you to throw a fit.
Breathe realize we are here to help each other. You received info on your request. If you don't like my posts you can see I posted maybe don't read them.
Greg Bushman my name is Les Hanson and I'm hoping you have a good night.
Les

changing the lower bearing in a hoover is a waste of money unless its completely rusted and siezed which yours is not. those bearings are completely serviceable and in my 8 years of repairing hoover uprights ive NEVER replaced a lower bearing on a vintage machine.

get a grease gun from oreillys and get the needle point attachment. get a tube of high temp synthetic grease (i use amsoil) and take out the felt washers. use the needle point grease gun and put grease in the gap. get a very small fine thin flat blade screwdriver and puch any extra grease into the bearing. you may have to do this 3-5 times to get proper grease packing in it. occasionally stick the armature back in the bearing hole and give it a spin. once it has a liberal spin down with no bearing noise, youre done.

What is the general consensus on Tri-Flo synthetic grease? Would it be a suitable grease in a case like this? I have a Hoover 61 where the lower bearing is dry, also a Hoover convertible 728 with the same issue.

Thanks

Will thanks for the advice. I use Lucas oil grease that covers same application as one you recommend. I know Lucas oil is pretty good but I look into the one you mentioned.
I only buy new bearings when they come in a bearing plate. I use the cleaner make sure bearing is spinning then lubricate with grease and seal. Good to know on bearings. There Hoover and the vacuum is old so I know they're good quality.
Thanks again everyone for help. I'm going to go drill out rivets and grease right now. I'm going to put in new replacement bristles. The carbon brushes are good. The vacuum is in awesome shape. I'll try to post when done.
PS it's my first Hoover and i know it's actually a great vacuum. I want to see how it compares to eureka/sanitairre.
