This morning is started work on my 700 after talking with rugsucker last night. I removed the fan and unscrewed the round plate off the bottom of the motor. Then removed armature. Next i did the same with the donor motor from the garage. When the fan was removed i thought "well lookie what we have here" three washers and a sleeve bearing that was not present on the original motor!!

 

Once everything was in order, work commenced. All components were cleaned and greased with vaseline  (best thing for moving parts on vacs in my opinion). While i was at it all carbon residue was also cleaned off inside motor housing. When all was looking better than it did originally i replaced the armature and decided to use the bottom plate from the donor motor just incase the original one had something to do with the cleaner not running right in the first place.  Next i slipped the sleeve bearing in place followed by the three washers. On replacing the fan it was found to spin freely with no rubbing whatsoever. Next the belt pulley was replaced and then secured motor back on to cleaner. I then replaced the belt and hoped for the best. 

 

Guess what?

 

IT RAN LIKE A DREAM!!!!!

 

The brush roll spins as it should with no slowing, rubbing or humming. Quiet running order as they usually do.  Boy does it do a great job on the carpets.  After a quick buff job to clean any smears or fingerprints, it looked fantastic!!! I must say i have been patting myself on the back all morning for a job well done. 

 

What i think after dismantling the donor motor is someone in the past removed the fan from the 700 and didn't replace the crucial parts afterwards. If they had then the washers and sleeve bearing would have been present when i removed the fan. The person probably noticed a few spare parts lingering around and thought nothing more about it or misplaced the still needed parts and didn't realise.  I have put it all right again and thus perfection was achieved.

 

I am so glad i decided to try my hand at the repair before having to locate a vac shop in the states that would be able to get it running. Having to post the motor, then wait for it to be repaired and then sent back would have probably been a bit expensive. I managed to do it for the cost of the donor motor i picked up from a vac shop that was closing a few years back.

 

I hope to have a photo shoot soon and then i can post them on a thread so all can see her.

Gary,

What a relief for you; its that pounding in the chest just before you pluck up the courage to flick the switch just after completing the re-assembly, I know this feeling as only recently I finished one of my dream machines: my 541....it to, thankfully, ran like a dream.....it purred!!!

Looking forward to the 700 pics.


Regards, Walter (Shropshire)

A few washers near to the fan and armature do make a lot of difference to the running of the motor as i have noticed on the 1334 Junior models that i own .A small washer of minimal thickness makes all the difference

Gary,

 

That's great news. I know you've been unhappy about this, so I am glad that you took on the job and finished it successfully. Amazing what some washers can do!

 

Congrats.

 

John

Hi John.

 

 I assumed the three washers were supposed to be there as the donor motor looked like it was not touched since it was made as the screws were a job to undo.  I was amazed to see them and the sleeve bearing being in place helps as was not the case with my 700 motor.  I do wonder if someone didn't put all the pieces back together when an obvious attempt was made in the past to repair it. I hope to get pics up soon.

Congratulations

... On your restoration. The three washers will be 'thrust washers' which take up the endfloat of the armature shaft. they 'should' be there.

All best
