My truck tipper motor hasn't been used for a few months, I went to do some work with it and it didn't work, stripping it down I found water had got in to the dc motor and caused the brushes to seize up and arc on the commutator.
@@ciberbri59 I was thinking that the motor was toast when he opened the case and water came out. I would have given up and bought a new unit at that point... but now I know better: I won't assume that a little water and corrosion means the motor is dead, it could just need a little lovin'.
In this throw away society that we live in its refreshing to see someone rework something that just needed a little love Great video and you showing that it doesnt take nothing but time and a little elbow grease to repair what most would replace
The real benefit is for next time or our kids to understand that if the world does go tits up then the people who can fix, repurpose, Engineer and create equipment to solve a need will be the families that will survive and should survive because there is a lot of wasted space with the Consumer network that is the root of all resource consumption. Every single person or family that inspires value into extending the life of a useful and valuable piece of functional equipment does more for our society than any scientist ever created. I also makes for better people who are less likely to believe your surplus to needs?
Nice - In the late 80's / early 90's there was a milking machine made in NZ which had fancy (for the time) electronics on every bail. They apparently tried everything to get them water proof, but between the high pressure hoses, cows kicking, grumpy farmers, water always entered, and most likely some issues were from condensation. The solution was a small hole in the plastic cover in the base to allow water out. Always remember this story from my first job. Simple and unexpected.
@@paulg3336 it's not brains that are lacking, it's knowledge. Big difference there brother, don't forgot who cultivates the food you put on the table and have a little more respect for farmers, thanks.
Marty - The big e-bike shop in Vancouver figured out years ago that, when motors (like e-bike hub motors) get hot, the air inside expands and pushes its way out of the motor any way it can. The main culprit? The wiring. The gap between the strands on stranded wire, under the insulation. And when the motor cools (bike parked in the rain, as it does often in Vancouver), it sucks water back in like a straw. The water gets deposited in the motor, and in a manner of only a week or so is actually substantial enough to fill the motor. Then eventually rusts it to failure. They tried sealing wire ends with silicone and everything else, and eventually threw in the towel and acknowledged that eventually water will get in, and what's important is that it can get out again. So, they enameled the whole inside of the motor with high temp enamel, and then drilled a bunch of holes in the motor case. Problem solved. Looks like you'll do just about as good here.
Forty years of doing electrical and mechanical work has taught me this. Water will ALWAYS find a way in but never find a way out. I try to set stuff up where any water that gets in can get out as soon as it stops raining and warms up.
This can be reduced to virtual elimination by putting a fitting on the motor and having a vent tube going to somewhere it will never see water or use a water trap. No suction occurs if the enclosure is vented.
@@paulg3336 My Winch manufacturer is now pushing this fix you speak of in Venting the motor, its funny to hear people speak of Winch motors drain holes being in the wrong place that the are underneath but then the winch gets mounted facing forward, so fundamentally its flaws and will always fill to half capacity no matter what. But the truth is as you educated guys have illuded to it will always suck water in unless vented and drained and this has now become my experience. Do you not find it amuzing that the guy selling items has no clue how it works? and he parrots what he was educated with by his employer that you must have had the winch under water and I could testify that in no time in 10 years I owned the vehicle and winch has it actually ever been near any submerging and in the housing of the Bullbar its sheltered in every direction from rain water to the point that I could pull the winch out wipe the dust off it and put it back on the shelf. But if something is guaranteed to fail by design fault and lack of knowledge then its good business? I have 4wd legends that every year they pull theirs appart and clean it all up which is the only way you could fix it or keep it in good condition The first one I blamed the seals which is the party line, the second one I was pissed but knew that it had never been under water so looked harder into the why more until now I understand you guys explanation as being the fact around it's failure and what prevents it
I took mine out, fresh from the factory, cleaned everything and used epoxy to coat the important stuff, then i drilled two holes, one in the bottom, and one in the top at the opposite end. Every time i know water had a chance to gather in, i use compressed air on the top hole and purge it out. It's been 3 years and change since i've done this and no problems have arisen, where as for example, a friend of mine bought one just like it because he'd seen me use it for years now and didn't ask me what was what, it died within 8 months.
@@paulg3336 So it wasn't so much that the holes mentioned in these replies let water out, but more that it allowed the internal air pressure to be level, so no suction occurs.
I would be shocked if the little fella don't grow up to be a mechanic or an engineer. Reminds me of myself as a kid and my next door neighbor. The old man was a machinist for the railroad company, taught me a heap of stuff. Biggest mistake of my life was not buying his tools when he passed, especially his Colchester lathe and bridgeport mill. His daughter sold them for scrap.
The old square bucket trick. Love those square buckets...good for painting, great for bulk storage...very useful. They should stop making the round ones.
👍 good work. Mine had a rubber duck bill drain on the end cap (not stock). While at the dump with a load of spiny branches. The three guy next to me started to laugh, until I push the button. Perhaps, the laugh was on them.
Watching Marty always reminds me of the STAR TREK original series where Spock says.. "I am endeavoring to build a nemonic memory circuit utilizing stone knives and bearskins...."
Another no-nonsense real life problem met with your common sense, excellent video and editing and a handsome young assistant just waiting to walk off with your hand tools!!
Nicely done! The only problem I see with your bucket raincoat is if you have further issues with that motor, you probably won't be lifting the deck to get to it. 🙂
I see your still repairing the auld road. Just hope another storm doesn't arrive. We had three here in Scotland in the last 2 weeks, massive storms resulting in flooding everywhere.
A friend gave me an old Mk1 Ford Escort Estate. It was so rotten the doors dare not be opened without jacks under the sills. I 'repaired' it and got an MOT test first time. I thought the starter was a bit tired so I stripped it, it was like fairy land inside, everything was covered in copper dust. The com. looked a mess so I stuck it in the lathe. New brushes and a clean / coat of paint and it lasted for years.
I had a 1969 VW Karman Ghia convertible, and it was very aquatic. The cure for water accumulating on the floor under the driver's and passenger's feet were one or two punched 1/4" holes recommended by the local VW repair shop. Worked like a charm. Of course, I got better and better gas mileage on that car as time passed, it got lighter and lighter as more rust fell off!
When you put that shroud cover over it you might want to consider a splash guard for the bottom in case you're driving in some heavy rain, and it throws water up and into it from the bottom. Good job. I've been convinced now after watching all of your videos that there's nothing you can't fix.
Hi Marty, was directed to you by YT about 3 weeks ago and have binged watched most of your Vids and the ram series , all brilliant but sad about Rambro Love your work absolutely brilliant, my best mate is a Kiwi, he lived with me and my family for six years but has just returned to the north Island to look after his mum. Have subscribed, all the best from the UK.
Marty, No need to disconnect any wires. Fix it on the machine and works just fine now. Thant was a lot of water. Glad the lift tester came by to make sure you did everything right….haha.
Maybe a cheeky regroove with a dremel on the commutator might be in order soon, She sounded pretty good on the lift though and your Sons comments were priceless :-)
I have worked on a few motors like that in my life, everything from vacuum cleaners to bench grinders, and even one for a water pump and one that had spend 20 years on a fishing boat. Pretty much 90% of the time they will come back to life by cleaning the commutator and either freeing up and cleaning the brushes or just replace the brushes. Usually apart from the brushes; the bearings are what wears out on these motors (again; also easy to replace). These type of motors are really hard to kill.
As usual, a terrific video on fixing something with tools at hand, some of them old and basic. You are allowed to ditch those disposable gloves and put new ones on Marty - we know your principles, but they've had it!
Makes me feel good that Marty evidently has the same set of Starrett punches that I have. From the video it looks like the insulators between the commutators need to be scraped down.
"EEEkkk, not that high!" hahahaha. Your little supervisor approved of the repair and gave it a wee test himself. Marty's new side hussle - motor and road repairs.
I’m enjoying the more frequent uploads. No matter what the content is, your videos are excellent. You work hard. I didn’t know you had a second channel that’s even larger than this one until just a few days ago.
Nice fix and water proofing. I believe that an older small wheel loader is looking for you. That would be a nice replacement for the old tractor loader.
Absolutely love your videos was just watching dirt perfect podcast and they got in the subject of the abandoned excavator that you got going how basically anybody who's been on the internet has seen your video of that it's amazing thank you
You don't clean a commutator (collector) with sandpaper! You turn it over with a lathe or clean (polish) it with a special rubber pen. Grinding roughens the surface and burns the contact. Once it has started to burn, it burns the contact until it is gone. I would clean the charcoal and the charcoal holder with a cloth and not soak it with a liquid. I would have replaced the two dustproof bearings for 3 dollars or at least removed the rubber on one side (cleaner site) with a knife tip, cleaned it and lightly greased it again. After carefully removing the rubber cover on one side, you can press it back on or leave it off. You can easily check an error of the windings with a measuring device. You're doing good work, I enjoy watching.
Marty this will do very well. I can't believe how strong that motor dumps. Must be geared down. Works very well on a pickup. Those scratches on the slip rings will do fine now water is not coming in. Should have left bottom on bucket. Probably only get water in it now with a flood like you just had washing the culverts and hydro station down the stream turned major river. We need some of that water in our SW. GLEN Canyon dam took 17 years to fill up. After full demon weather overflowed it so bad cement 30ft deep was washed out in overflow tunnels. We then learned on the steep tunnel face to have 5ft overhangs with which to inject air into stopping the impact of the water down in the bend at the bottom. It flooded over the next year too. Had this flood come 15 years earlier the amount of hydropower would have been generous. I am now a proponent of molten salt thorium reactors and leaving the rivers alone except for irrigation, not power production. All the dams on the Columbia have totally decimated the salmon runs and ruined the hydraulics of the river. Before my time Wenatchee horse teams took cross cut saws out onto the river to cut blocks of ice insulated with wood shavings for ice all summer for fruit shipment, till refrigeration from the hydro dams. It has never froze over in my lifetime and I am 75. So thermal inertia is a real thing behind the dams.
Fix another problem. Then go use it on the driveway. A lovely theme to the channel. Can't wait to see what the driveway looks like in say 5-10 years from now. You'll be able to paint lines on it by then I'd think.
I was watching this and thinking of a used oil container with the top and side cut off for a rain guard and low and behold, Marty went one better and attached it to the underside of the tipping deck, genius.
Marty I am an avid follower I love what you do!! I'm a union sheet metal worker in California making $51USD per hour and I would trade my life and income for yours in a heartbeat. I love what you do and please don't stop sharing, I thumbs up every video. *Cheers
Update Sir I salute you I took my mates whole unit off today and took it to my workshop did the full strip down after watching this video yesterday and your bang on 2 bushes stuck solid and the copper rota black rotten. It was so easy to do and once back together it sounded better than ever. Thank you sir
Good job Marty! Don't know if you ever heard this, but an old mechanic told me those pry bars also make a dandy tool to drive screws with! Who knew?!!! ;)
Well done bringing it back from death :-D I'm always amazed how long d.c motors last, the commutator/brush switching is crude. Starter motors are so brutal on the switching, the current passing is utter madness.
Great fix. I have a 1961 Chevrolet Apache 20 with a hoist with the factory box. Hydraulic is PTO driven. Acquired it in the early 1979 or so. 80 small straw square bales for the truck. Put a 3/8 4x8 plate on the floor of the box. Still use the truck today. Sure is handy. I think my dad bought that truck for me because I was his rock picker.😄😄
I have the same hammer but my boy is all grown and gone. It's OK. If he hadn't grown and gone it would've been problematic eh? Your videos are always a treat.
The white poly buckets have a pretty short lifetime in the sunlight - there's no UV blockers in white and clear buckets. Keep your eyes open for a black bucket, or some aluminium to shade the exposed area. I used some aluminium duct tape to good effect on some exposed poly on one of my projects - still holding up! Nice fix - you are a great teacher of the slow and methodical method of trouble shooting and repair. So many farmers run with quick and dirty repairs, when they're just sweeping their little problems ahead until the whole pile of them light up into catastrophic failure! I hope the younger guys are taking notice that doing it right once, or even doing it as well as one is able at the moment, will save time in the long run!!! Cheers from California.
That rain cover was literally the outside the box thinking! I was thinking how I'd mount the cover around the motor but no, just attach it on dump bed, simple.👍
Problem? Solution : Can of squirt and an old bucket. Just goes to show, you need to think your way through problems like this. Awesome as always Marty, would love to have seen you helping Diesel Creek with those bulldozer rams last week!
Hello Mr Marty as always you are just so calm and so relaxed when you working on stuff. I tend to work on things I get frustrated and Grumble to myself but then again I don't have a large audience like you either way I enjoy it I always look forward to your videos and and thank you for doing it you have a good day best regards Bob from Virginia USA
Thank you Marty. I suspect a lot more people will now feel easier about investigating electronic gear in wet environments, such as boat motors and the like.
