There are 3 screws total that hold this C9 together. 2 in the wheel openings in the body, the back regular wheels, and one up front that also holds the 2 plastic retainers for the powerhead cord where it plugs into the body. It splits exactly in half with a bit of convincing around the rubber bumper to pop it open. Once it's open the motor is right there with all the wiring. Your machine should have been similar I'd think but it looks like the bodies changed a bit over the years. There are a few exploded diagrams online at the big vacuum repair sites around.
It truly is a very simple design with not a lot of complicated parts to deal with. The hard part was figuring out how it came apart but once I saw how it was done I only spend a hour or so swapping out the motor. It fired right up nicely and was pretty quiet. The smaller powerhead gets between tight spots easier and I'll play with it and see if the powerhead motor starts running smoother as it gets run and the oil gets around to the dry parts. I couldn't figure out how to pull it and not sure how to tear down the main motor either but I really want to see whats loose inside it.
 
Wonderfull !

Perfect i actually did find the screws after i ask this question haha . Thanks !
I wanted to know because i had my Compact C9,(same as yours but blue ) vacuum cleaner for a few years .And motor runs strong and smooth just wanted to know and check, if any thing at all needed replacing just to be on the safe side . All i did was change the filters and bags, also a new hose . My power head has a chevron style brush roll and ive also replace the power head motor , whit a genuine compact motor .Now i recommend you replace your power nozzle motor whit a new one before it seizes up on you during use . I f you ever need information on your Compact C9 re badge contact me . I am so glad you got your vacuum working again .PS vid of my compact

I didn't realize you never opened yours up so glad to help with the disassembly instructions. As you found out it's not obvious at first how these things are screwed together but between Google and here everything can be figured out. They also sell new brushes for various versions of the motors cheap but haven't found any bearings for them yet but a new motor fixed that issue. Your lucky yours was still mechanically fine. Like I said maybe that's why we stopped using it later in it's life as it got badly noisy when the bearings went away and I had moved to my own house and eventually bought that 413 Royal I still have that also works great.
Now I want to figure out how to disassemble the motor to see what is bad and what came loose internally. Somebody here ought to get that extra power motor for 69 and see if it fits and works better. It's only about a inch longer and other than that is the same diameter and all that so should be enough room in the case to use it. Your unit is probably like many things in Canada, made locally with US and other parts to fit your market, like the old Mercury/Ford trucks, and I believe some early Valiants that actually were Darts in the USA.
 
my Compact C9

I bought my machine on ebay and made sure i had a good working compact . Shes been trouble free ever since i got her .Now shes been repainted ,a new hose new motor in the power head new tristar compact original NOS replacement hose ,seems longer than my previous one and crush proof ,new exhaust cap ,enviro care papper bag ,cloth bag and motor filter . The motor in mine has never been touch as far as i know shes like factory internally maybe thats why she pulls so much suction and has extremely good air flow no one mess whit it .

Great, the powerhead on mine did OK for another 10 minute or so run so maybe the oil started penetrating all the dry areas in the bearings and bushings as it was probably in that closet untouched since 90 when they bought their manufactured home she still lives in. If she hadn't decided to clean out that closet it probably would have sat buried till she leaves us. She just bought a new Shark and now she says it's hard to push but I guess it works great. She had a Orek xl upright and probably a few other plastic garbage vacs she gave up on. She should have fixed up the campact and maybe kept one of the Kirbys she used to have and she would have been set for the rest of her life.
Pretty sure I told her I'd find her a Old Royal or give her one of mine but she got a deal on the Shark at Costco.
 
Yes if shes older cheap vac are easyer to push il stick to my Compact C9 no matter what glad you got yours running again.could you post a pic of the finish product

Congratulations on doing the motor transplant & getting your Compact working again. Yours is definitely a unique color & variant for sure, & will be a conversation piece in your collection. It's also nice to keep vacuums that have family history too. I also personally like the Compact PN that's a re-badged Eureka Roto-Matic with the bleeder valve instead of the TriStar PN they lade mater based on the Eureka PN....it seems to me that the brushroll bristles seem to stick out the bottom plate & groom slightly better than the TriStar PN does. And the straight-suction hose with PN cord on the outside would be more reliable & trouble-free long term than the electric hoses would be. The only thing I would suggest, since Eureka Roto-Matic parts are becoming more scarce as time goes on, is I would pick up a spare powerhead internal hose, just to have on hand when it requires replacement. Over time, those hoses will develop cracks & breaks to the point it will affect the vacuum's performance & need replacement.

It's probably best to just throw out the old motor. Sure, they are easy to repair if you wanted to, but they are so inexpensive to replace you're likely to spend at least half what a new motor in parts to repair the old one. Plus, being from the late 1970's, that motor's electrical components have so much wear & tear on them, it has a relatively short life left if it was able to be successfully repaired.


As for that motor that was a higher power version & slightly longer, that is a Ametek 115923 motor the Ebay seller was also offering. Consider yourself lucky you stuck with the Ametek 116311 motor you bought that is original to Compact/TriStar vacuums. That 115923 motor will NOT fit the Compact vacuums, ONLY the TriStar vacuums. The reason is, when you pulled apart your Compact you would have seen the blower end of your vacuum is part of the magnesium body. If you take off the exhaust diffuser, you will see there is a plastic ring riveted in place that has the lugs to attach the exhaust diffuser. In the early 1980's, Compact was turned into a vac shop brand for a short while & the first red two-speed TriStar was introduced. The first TriStar CXL single speed model after that saw the design of the blower port changed, it was no longer built into the metal body but turned into a plastic blower basket riveted in place that has the ring for the exhaust diffuser built in. Those TriStar CXL & DXL canisters after the red two-speed model can take that Ametek 115923 motor, as the blower basket can be trimmed & modified to take that motor.

However, for people that own a Compact, are in need of replacing the motor & want to upgrade it's performance, there is another option available. Electro Motor, the original Aerus Electrolux motor manufacturer, was the motor used in the TriStar EXL. This was changed with the TriStar MG1, though, when Electro Motor was sold off from Aerus. There are 2 versions of that motor available that will fit perfectly into Compact & TriStar vacuums. The LH0274 on the website linked below is the standard replacement motor for Electrolux 2100 canisters, & pulls 100" waterlift, same as the Ametek 115923 does, & is carried by most vac shop suppliers & found on Ebay quite easily. The LH6500SR motor, though, is a HUGE improvement over the Ametek 116311, 115923 & LH0274 motors, though, & pulls a whopping 117" waterlift. Both of these motors are the same dimensions as the Ametek 116311 motor, & should fit perfectly in their place. When installing the new motor, you would have to cut off the wires from the old motor & put on a couple of 3/16 inch female disconnect terminals to connect the new motor. Also be sure to put some Pliobond on the rubber motor mount to be sure that new, much more powerful motor stays in place once installed.

Yes the motor he put in his Compact is a factory replacement the other one will not work glad he got his unusual Compact C9 working again .
 
drayman,

I agree with your idea of possibly....getting her a Royal upright. I find them EASY to push/pull. aka 'clean' the carpets and they are so powerful AND....no maintenance really...nothing to break....no clogging etc
 
Wow, been busy on my thread since I last checked in. My sister has the day off and decided to use the c9 to clean up her room and hit some of our parrots favorite spots to mess up. It was working fine, sounded fine and she was in cleaning her bathroom rug when the powerhead belt snapped, not surpring considering how ancient it is so it kinda outa commission for now. Starks here should sell belts locally she'll probably head over during her outings tomorrow and get a new one and see how it goes. The powerhead motor seems to be doing ok once all the oil soaked in. I wondered why she was using the Royal 4650 when I got home what with the new old toy to play with. Thanks for the info on improved yet will fit motors, I can always modify or add connectors to make them work and I love modifying and tweaking anything I own to improve performance as long as it doesn't destroy the unit.
 
It still has the cloth bag it came with, a ancient paper bag that is easy to dump, and the foam motor filter it came with and the little chrome foam exhaust filter so pretty much as delivered with battle scars. We'll get the belt and see how it goes. That fancy hepa exhaust filter might be something to try later if everything seems stable. Good thing I have a stable of working vacs now and they are talking about mom giving me the old Royal 501 tiny furniture vacuum she's had around forever that I don't think she ever uses now. She's always had it and I can't remember how she got it but sister thinks maybe she got it with Green Stamps, remember those.
 
well the filter fresh been known to restrict air flow from exhaust port is what i heard .I run my Compact whit, enviro care paper bag, cloth bag, foam filter , and the difuser cap and have no issues what so ever . get a new belt and your compact will be back to cleaning like the beats it really is Best of luck nice to see it running .
 
She got 2 belts and some more bags for the Royal 4650 today and I just installed one of them. Both motors are still running smooth and beater bar is humming along again. Lady at Starks knew exactly what belt she needed when she said she needed a belt for a Tristar/Compact 9. She also said those bags aren't for the Compact you got the belts for. She said I have all kinds of vacuum and I like them and she just nodded, yep we have customers like that.
I just got a 10 pack of bags for the Royal but she wanted her favorite hepa high quality bags I guess and they sold her 3 more of the cheap bags again. The belts came in a 2 pack and was like 6 bucks.
I wish she would have bought some new bags for the c9 but I didn't tell her that it needs new ones... Oh well, it's back among the living again and I cleaned up after bird yet again.
 
Thanks, I'll have to check on those and some for the Royals too as those are the ones sister says she likes best in the 4650 but we ran out and I got a 10 pack of the cheaper ones.
 
Got a 12 pack

Ordered a 12 pack, surprisingly Amazon was a few bucks cheaper with free prime shipping so they'll probably be here Saturday. I spose I could order some for the Royal too but now we have a ton of the cheaper ones to burn through and I think the hepa part of the Royal is a bit better no matter what bag is installed. The bags were 6.88 shipped with Prime which if you order a lot of things through Amazon and like decent streaming HD videos is actually worth signing up for what with fast free shipping on most things.
 
Well thats good it will perform great whit a enviro care paper bag and a good cloth bag . Im glad you got her working again . I use my Compact C9 daily and love it my brush roll is a chevron style brush roll and works wonders on my rugs and carpets i have an electric hose on mine tho .Whit a new motor and bags it will last a life time
 
I have a 12x16 mini barn shed with a loft and 4 br so one is kinda the everything we use a bit but don't want out in the shed room so a bit of storage but could always use more. Put one of the new bags in as the 30 or so year old one was pretty full and worn out. You can dump the bags easily and reuse them if they aren't too nasty so that's nice and different. The powerhead seems to run fine now but seems to bog down a bit on the rug but everything works and isn't making bad noises anymore.
