Window Motor...

on Mon Nov 05, 2018 10:20 pm
So my mate gave me a window motor out of his 72' Rolls Royce.

It would go down, then up very slow or sometimes even stop.

So I stripped it and found the reason...The worlds finest automobile seems to have skimped on a bearing! Rolling Eyes

There is a bearing at the business end of the motor, but at the back end, they put a ball bearing into the end of the shaft and in the end of the motor housing there is a screw & a locking nut. I could see this is to take up any slack and basically keep the motor shaft straight & true.

Now, the reason for the slow/stoppages is the bearing is on a pivot which allows about 3 degree's of shift if the ball bearing at the other end of the shaft hasn't been adjusted. I would imagine these would be part of a major yearly service and have been missed for many years (this car spent a lot of it's life in Spain).

So, the slack has allowed the shaft to pivot one way on the glass up and the other on the glass down. This in turn has allowed the brushes to wear at an angle to the extent where it has gone from 100% contact to about 10% contact. This in turn has caused resistance and a demand for more amps which has started to burn a narrow band into the rotor contacts as well as the end of the brushes so the resistance has gone into infinity causing the slow downs & stoppages.

All I did was use a willy nail file Laughing wife uses a glass nail file and wouldn't give me that, but she had a jokey one from an Anne Summers party many years ago... Laughing ) and shave the angle off the brush ends to make it a bit more flat.

Rebuilt it and it goes well. Tomorrow I'll try putting a load on it just to be double sure.

The only thing I couldn't do was remove the drive cog off the end of the shaft Mad

The motors are available if push comes to shove, but they cost more than an arm....https://www.introcar.co.uk/window-lift-motor-p93711 Shocked



I'll look into how to remove the cog so I could replace the brush set which are available for Mini's and the like

£320 window motors, Mr Rolls Royce you are really spoiling us

At least it was a unit you can open up and repair Doo, hopefully the filing did the trick

Look again at the replacement motor Paul. They aren't even new, they're reconditioned! 😳

Clever? You think?

Nah, Spot is clever with his computer genius. Eff Eff, Paul, Iaiaiaiaian, you, all clever.

I'm just a fat mess with a little mechanical knowledge and a way with words is all.

But thanks for believing in me Crix Embarassed

Clever / intelligence / ability all takes many forms

In the sane way we all learn new stuff in different ways

£320 recon - ouch!!

Go round buying stuffed motors Doo and recon them with your new nail file

Here's the photo of the brushes, you can see the lower one has a definite slope and you can see the scorch marks on the slip ring where the brush had burned it.




I didn't take a photo of the finished repair because wife was using my phone to watch Coronation Street...🙄

Anyway, here's the motor back together and the file beside it 😁




I'm planning to scrub off the rusty coating and spray it black to give it a better look. After all, it's going into a Rolls Royce 😎

To have the ability to fix anything from relatively new small Japanese hatchbacks to decades-old British luxury saloons is pretty damn special! Smile To put it into perspective, about 4 or 5 years ago when I worked at a particular franchised dealership, a new-ish car came into the workshop (same mainstream brand as what the dealership sold as a franchise) and needed a replacement head lamp bulb. It took 3 straight-outta-college, wet-behind-the-ears technicians and YouTube to figure out how to do it... Laughing

Are there any photos of the Roller available? Who doesn't love an old Roller?! They're great old things! Smile

I took a photo of it recently.




I drove it to a classic car show earlier this year. George is nicer to drive if I'm honest. The steering wheel is so thin it was like holding a round wire coat hanger. But, I have to say, the big V8 under the bonnet has "adequate" power 😉

The fuel door is off as he took it to get paint made up, but it is a "made up" colour as in not on any Rolls Royce colour charts. It was sprayed in Spain where it spent may years, but the rear arch has bubbled up a bit. The guy he uses to paint is amazing! He did the white Rolls and the job is astounding, you cannot see the "join" nor any difference in shade.

Here we go... https://gsmweddingcars.scot/

I forgot I get a mention on the website, "All our cars are maintained to the highest standard by our in house technician and come fully valeted on the morning of your wedding so they arrive in pristine condition" Razz

That's kind of a bit of a huge compliment Arrow

You keep your hands away from my bush you dirty bugger 😂

I wish I was mate, but I'm really not "that" great. I'm sort of mediocre. I do like fixing, but sometimes it takes a couple of goes to get it right. A real mechanic gets it right 1st time every time.

Maybe one day...

If a real mechanic gets it right first time, every time, doesn't that mean he's reached his full potential? Whereas a mechanic that makes a mistake and then rectifies it is learning and still on a learning curve, so the potential could be limitless? Wink I guess the best people of any trade never stop learning. Smile

I'm not sure what you were saying there Eff Eff, but I can see there is a compliment in there so I thank you , and Crizzle for the kind words.

I just can't seem to accept I am good at anything, especially the shit storm I'm currently trying to navigate.

I'm really struggling right now with the lack of money. I used to make in 2 nights what I get a month now and the fact I can afford to run my car for one day really hurts.

I've seen the specialist who told me if I had an operation, it would be highly unlikely to succeed (likely be in a wheelchair) or if I get injection into my spine, the likely hood of a stroke or death is increased due to my diabetes is very high. So, as per, I somehow get another tonne of shite piled on... After what I've been through, I can't take the chance!

So, looks like the rest of my life is going to be a painkiller sandwich 3 times a day and feel like a half shut knife or miss some out and be in more feckin pain!

And no, I don't feel sorry for myself, I'm just a bit fucked off about the whole thing Mad

Any ideas then chaps??

Not entirely sure what I was saying myself. Wink I think I was trying to get at the point that the 'perfect' mechanic will never be any better than he already is, but somebody that still learns things is getting better each day, and could potentially end up being better than the 'perfect' mechanic at some point. Smile

Not really sure what can be done about the pain situation. Sad My mother's a nurse and says there's no need for anybody to be in pain in 2018 with the medications available these days, but obviously costs come into it with the NHS and resources, etc. It'll be no consolation, but it seems everybody these days is on medication for something - the amount of people I come across each day that take tablets for something or other makes you wonder how the human race has survived for so long!! Thought humans would've been extinct long ago by now. Laughing You're not suffering alone, though - I knew a lady that chose to jump out of a 2nd-floor window with a baby in her arms as somebody was threatening her with a knife (the baby was absolutely fine) - she broke a vertebrae in her spine and lives with constant pain, dealt with by pain injections every so often and some tablets. My other half suffers from fibromyalgia - a condition where pretty much everything hurts to some degree, near enough all the time; she's on a myriad of tablets for that and other things like silent migraines. I guess people are like cars - we all go wrong eventually (be it naturally or otherwise) and need patching up.

My sister, her friend and someone I know from school (all that time ago, when dinosaurs roamed the earth...😁) are telling me I'm suffering from fibromyalgia. The pain is everywhere!! Walking, sitting, bending, lying down, all painful. Even touching my lower legs hurts!! Inside, outside, it's everywhere, but the doctors seem unconvinced so I plod along taking painkillers during the day and a painkiller and whisky, gin, vodka, whatever I have at night so I can get at least 3hrs oblivion. I know it's far from ideal, but it's all I have right now. Then I wake, absolutely shattered, read for ten minutes, drift off, turn & turn & turn, not finding comfort.... Same shit every single day.

It might be worth investigating the fibromyalgia route some more - it took a good while for the Mrs to get her diagnosis as apparently it's a bitch to diagnose with the symptoms of "hurting everywhere" being quite vague as far as medical professionals are concerned. Her tablets do generally keep it under control, but the odd flare-up does happen now and again.

Is it the pain alone causing lack of sleep? Have the doctors tried you on Zopiclone?

No, I'm being put on Naproxen soon for the neck/back pain as it's a stronger version of ibuprofen or some such. I'll see how I get on with that. Waiting for a call back from doctor today. Need advice about how I feel... All anxious and weird. No confidence, don't like going out by myself. I just feel wrong!

The other form of relief, that I know works ..

... and that most of NotParkers swear by for good relief is Lelkanovikov.
