Basically a neutral start switch to the control module with the potentiometer for your graduated forward and reverse going through a foot safety interlock so there's no way it will move. Good find, hope it's fixed and no come back.👍 you're right without the scanner that would have been a pain.
I watched a video of a railroad engineer giving a tour of the largest diesel locomotive engine ever used by Union Pacific Railroad. I was surprised when he said that they never changed the huge amount of oil in the engine. He said it used a lot of oil, so they just kept adding gallons, and changing the 2 giant oil filters every so many hours of running time. Looks like someone thought that would work with the lawn tractor, leaving out the filter change part too.
If they run their EMD,s like the marine field, the oil goes out for regularly scheduled analysis. If it comes back in spec, we keep running it. The 12-645E2s we ran used 275 gallons of oil and 14 oil filters.
As you know or are finding out, there's a lot of platform lifts out and while they're well made and go for years trouble free the service market is all yours Ivan. " and it couldn't be in better hands " very few people work on these machines, I'm very happy seeing you put your skills to good use
Ask them if they had a problem with it turning over. Briggs and stratton had problems with compression release coming apart. Note: Briggs and stratton filed for bankruptcy protection 2 weeks ago.
Wow if Briggs and Stratton is in trouble, there is no hope for the manufacturing in this country. They were the #1 name in small engines, bulletproof. Sad times :(
Do a search on B & S compression release, you will fine many videos on changing the CAM, I had to replace CAM on 21 HP Briggs engine lasted 1 year and had same problem. Bought a new engine since the riding mower was only 5 years old and had a lot of life in it, engine cheaper than new mower.
@@joecoyne5660 I have replace a handful of them this year. They have had problems with Governors also. Briggs has a long history of put out engines with problems. Example, 1990 4.5 ~6.0 hp gas tank with a leaking on/off built in to the tank. Then the 8~12 hp had a leaking air filter housing (2 layers would not seal) causing every engine to need a short block. Briggs came to our shop to look at the old engines. I could go on for a long long time.
@@PineHollowAutoDiagnostics - Yeah, they couldn't compete with the Chinese engines out there, and started cutting corners. I'm actually surprised they lasted this long. You can buy a complete engine at Harbor FRIGHT for less than a piston and connecting rod for an old school Briggs!
Hey Ivan, that Briggs & Stratton engine just needs a good steam cleaning. Dump all the pieces out, steam clean it and let it air-dry, it's a very important and a crucial step to let it air-dry! If you don't let it air-dry it will not work once put back together with fresh oil "no parts required". You're welcome!
Watched this and thought that like his other jobs on these, the bonus footage would be he had other problems.To my surprise,Ivan gets an easy one!!!!!👍
Ivan your a champ at these, nice little earner as i'm sure almost every one of these out in the field has various faults. It's a tough machine exposed to rough handling in hostile environment.
Wow, that Briggs let go every which way! Lube failures usually result in the big end seizing, then breaking, and you get what you have here. Surprised it didn't come out the side! Nice easy one compared to that GM truck throttle body and APP sensor nightmare! Looks like that scan tool has already paid for itself - those guys will keep you busy! Well worth whatever it cost. You'd have had to test every wire in that thing - would've taken forever!
That pot on the joystick just looks like an ordinary type, i would of expected a sealed industrial type on such a machine. Speedy fix ivan :-D. The motor could also have been run too fast and too hot, eather way " It's worse than that it's dead jim...Err ivan " :-D Not even the ledendary russian fix can fix it lol.
That crank can probably be saved. I’ve done it before. Drain cleaner/muratic acid will eat the galled aluminum off the crank journal. Then a light polish, mic it to make sure it’s still in spec, and Bobs your auntie!
Ivan, I hope these construction folks pay you in cash as soon as the job is done. Not sure how smart it is to be building that much new housing in a college town the way things are now. I also live in a college town and the housing market is not good right now.
I believe their idea of ever is about 3 to 5 years, probably about when the mower deck, bearings, belts, wheels and the rest will be falling off and broken anyway, costing more to repair than replace the whole unit. to be fair a push mower only used for trimming with synthetic that's kept topped off, could probably manage that. providing the carb. doesn't flood over thinning the oil to nothing and it's ran long enough to get nice and hot each time, to keep from condensation oil thinning/acid loading.
Phfffffftttttt.... a little superglue, that motor will run like new!! My grandfather once told me that those little engines work very hard. If you don't take good care of them, they won't work at all. I change oil and filters in my John Deere riding mower once at the start of the mowing season, and about mid-summer. And I use Amsoil 100% synthetic small engine oil in all my 4 stroke engines. Have had the John Deer mower for about 16 years. Runs like it was new. It is surprising how some people criticize me for doing this, like it is a waste of money. The JD has a water cooled V-Twin Kawasaki Heavy Industries 38 horsepower fuel injected gasoline engine in it. It has a PTO and a 65 inch mower deck, swinging 3 blades, and a fully hydraulic transmission. You tell me if I spend too much money to keep it purring like a kitten.. And when I mow, it is FULL THROTTLE. Never has complained, never thrown a rod, never given me a second of trouble. I ran the valves this year, and only one needed a small adjustment, about 3 thousands out of adjustment. And flushed and re-filled the cooling system. Take care of your equipment, and it will take care of everything you ask it to do.
I think those Briggs engines are noted for camshafts breaking. Lots of carnage there, hard to say what broke first the cam or the crank. It's was one of those important parts, lol.
Maybe I'll call you Ivan the scissor lift whisperer!! Hahaha, great simple fix. That scan tool is a must for the lift jobs!! Great video!!! Pity about the briggs engine. That engine is shot!! What it came from?
A co-worker asked me to look at his 3 year old lawn mower that was making a "banging" noise. I arrived and checked the oil. "When was the last time you checked the oil???" (Empty) his reply, ""you have to check the oil in these too?". LOTS of kibbles and bits also...
Never hurts to check solder joints of connector on flip side of pcb for some added assurance. Btw, I bet there's a lot of Nittany fans up there having withdrawals with the season scrapped. :(
Oh man canceling Collegiate Football is going to cause soooo much pain since entire college towns are built on that foundation. It's crazy. I know a lot of people who are very upset about this decision...makes one wonder what influenced the decision makers...
The university presidents make the call and they weight heavily on the advice of the medical professionals which I'm sure played a major part influencing their final decision. Talk about a tough call in sports with the loss of millions of $$$ generated vs safety and liability concerns.
I have two of these for sale one gas one Diesil. Both have outrigger Jacks and 2003 and 2007. Older JLG before 2003 didn't have diagnostics and were much more difficult to troubleshoot. JLG uses a square wave generator to vary hydraulic flow to function s. JLG is John Leslie Grove of Grove Cranes from Pennsylvania now Manitowoc cranes using Krupp and Manitowoc cranes National boom trucks. The best! 24/7 crane care hotline support free service parts books. All made in America except for Krupp AT GMK cranes of Germany .
that's a full flow oil filter on the briggs. with the cam twisted off in the sump and the scored crank and broke rod i'd say it was a plugged filter. bad thing is the placement on those for the sender is on the pump side not the engine side of the filter so the pump was just relieving all the time, nothing was getting oil.
I have a 26hp Briggs & Stratton extended service life engine that had just over 4000 hr., it was the power for a Scag commercial mower. I replaced the old engine because it was starting to burn oil and I use it nearly every day I need the mower to be reliable. A new B&S 27hp engine cost two years ago around $965.00. I was surprised that B&S lasted 4000+ hr. whereas a water-cooled 29 hp Kawasaki engine, I had on my other mower only lasted 2780 hr. and it cost $2300.00, go figure. It can be the governor out of adjustment, that can cause the engine to rev higher than intended.
Excellent diagnosis....Once again the Crusties stop another piece of outdoor equipment....Would it be counter productive to remove all the connectors in that box,spray them with Deoxit and finish them with dielectric grease? It might prevent a return to that unit, but a loss in a repair fee...
Logically it would do that. The joystick position value is taken directly from the engine computer. So it just sees the whatever value there is and does stuff accordingly. If the value would be out of range (+/-110 or something), that could cause the maschine not to go for- or backwards.
Need your help. I have a JLG 1930es that I bought from an auction, but while it sat until I picked it up, the ground control, platform control and wiring harness were stolen. I need to know what wiring harness to get so that I can get it running . I bought a platform control, still looking for a ground control.
Just curious, what was that single orange wire dangling loose that was not connected? It looked out of place! Wish you could have shown how you repaired the wires in that 4 plug connector. Good video.
Not sure about the orange wire haha. Connector was just little pinch screws holding the wires in...nothing fancy, just hard to rig up a camera in the air :)
On the Briggs I can think of another reason for the carnage. I recently had to replace my cam because I wore the lobe off. This cam is my 3rd one and I think it's because I use my rider to cut an extreme bank in front of my house and probably starve the oil pump. Do you know how this engine was used?
That's usually not as much of an issue with pressurized lube engines. Push mowers with the dip finger and no pump don't last long on angles. Of course, it needs to have the correct amount of oil in it to start with, pressurized or not. This one could've been low, and starved the pump on the last hill they mowed. With worn out oil, it won't take long to seize a big end and destroy the engine.
technically if it first read negative 8 percent you could infer which ref was high resistance, -ve percent was 2.5 to 5 volts so to elevate the voltage the extra resistance would have been in the ground wire, if it had been +ve percent the voltage would be lower than 2.5 volts due to resistance in the 5v ref wire. does that make sense?
Diagnosis isn’t something you learn in a lesson , learning the skills of good diagnosis go on every day . I suspect Ivan has always been curious, even from a young age and pulled things apart to learn how the worked . Understanding the basics of how something works is the key to fixing problems when they don’t .
Having a good background in physics and electronics helps a lot. But the most important tool is common sense logic, which only comes with lots and lots of practice ;)
@@PineHollowAutoDiagnostics why do people not change the oil in there lawnmower and chainsaws why do the companies not have a book like car companies do that tells you how many hours until you should change the oil
