The actual quote was something like "I was just mowing along, the engine stopped and wouldn't restart. I looked down and my feet were just covered in oil!" Kohler Courage single cylinder consumer engine, about five years old. Split entirely in half. The cylinder and head were still around the piston when it came in, retained by the muffler assembly and blower housing.   Even though the unit was three years out of warranty, Kohler bought the customer a short block. Total cost to the customer for a new engine is going to be around $215. Saved our asses, too, because we had just done a total service to the mower.

Billy Tully posted:Holy poo poo I've never seen a failure like that. Were you able to determine what caused it? Big Box stores demanding equipment made to lower prices every year. Companies figured out that customers don't do ANY maintenance for years at a time. Then, the question becomes why build maintainable OPE that will get ignored and trashed in 5 years? Why not just build equipment that is going to last 5 years with no maintenance and build it cheaply so they'll be able to buy a new one when it breaks? Single cylinder Kohler Courage - sucks. Twin cylinder Courage - ehhhhhhh. Kawasaki FR series - better than the courage. B&S "professional" singles and twins are like the Courage except with less unexplained valve cover leaking and split crank cases and more carb problems. Four times the price gets you four to six times the longevity. Briggs Vanguard, Kohler Command, all non-FR Kawasakis and the Honda GX engines do this.

Well here's another one. More of a horrible maintenance failure, though. Mower has a 5 year warranty, end to end. Customer buys one, does NOTHING to it for three years. Air filter turns into a brick of awful, engine starts pulling air from the crank case along with the oil. No oil = YAY! "Fix it. It's under WARRANTY! I paid A LOT OF MONEY TO YOU PEOPLE!"     Note there are TWO air filters pictured. This is a common occurrence.

It goes something like concrete cutter>tiller>leaf vac>chipper>lawn mower. You should be checking oil every time you operate anything, changing it every 6 months on the lawn mower and every 8 hours of operation on a tiller or concrete cutter (if it's 4 cycle). If you keep your AF from plugging, change it every year and even just keep the oil topped up, you can get a B&S Quantum based engine to run for 15-20 years.

lazer_chicken posted:Is it still common for lawn mower/tiller/etc. engines to be sidevalves like that one is? My father's 1990 toro lawnmower proudly proclaims "OHV" on top of the engine cover. It's also been used non-stop for the past 21 years and still runs like a top. I does get somewhat regular oil changes, but I believe the original spark plug was just changed in the past couple years. The B&S Quantum engine came out in 1986 (?) and has been the mainstay of walk behind lawnmower engines since then. Tecumseh walk power mower motors were all side valves as well until they went out of business. Honda has done the OHV and OHC thing for decades now. A 1990 OHV would be quite rare, I can't even think of what engine that might be. All the companies *make* small OHV engines, but they don't have the proven track record or durability of the side valves. In fact, the B&S Quantum motor is so ubiquitous, we order those slightly rectangular air filters, 491588S, in boxes roughly the same size as a U-Haul size large.

Command >>>> Magnum. There's just no reason to go with a Magnum except packaging. The line ended in the early '00s, but it's already a parts wasteland. You can get more and cheaper parts for a K series than a Magnum.IOwnCalculus posted:Yeah, the performance that people need out of a small engine doesn't always necessitate the benefits of a OHV/OHC arrangement. With a flathead you get a cylinder head that's extremely simple, and two valves driven directly by a cam (that can be driven by a gear off of the crank). OHV you need to at least add pushrods and rockers to it, maybe even lifters? Never seen a GX pulled apart. I've never seen a GX pulled apart either. Or in for repair at all, just maintenance. The new GXes are very advanced, no word yet on reliability. There's no headgasket. The cylinder and head are all one piece. The pushrods ride in aluminum tubes external to the cylinder itself for extra cool operation. You look at the parts break down and you're like :aaaa: The lead tech at work has been working at this shop 15 years. In that time, he's never had to do a shortblock on a Briggs Vanguard V-twin. Ever. They are vacuum sensitive engines though. Any leaks will result in a mean surge. Kohler Commands have hydraulic lifters, no adjustments. Kawasakis have flat tappet lifters and require a valve service every 300 hours that no one does. By 600 hours, though, you're really noticing the wear. $500 later and it's purring like its new. The new FX series had some serious issues. The fuel injected version had its own problems, but all the high horse power engines needed a new camshaft and two new heads. Kaw pays out about $1300 per engine in factory directed mods. They might as well have not even made the engines at all. lazer-chicken, I forgot about the Suzukis. Those are fun on parts. A fuel needle and seat alone can run $40. Yes, they were hideously reliable. Sorry for the horrible derailing. I'll take pictures of some ruined Stihls tomorrow. e: ok I lied, I found some more crap. 3000 series cub with what, IIRC, was a leaking charge pump. Sorta collected all that dirt and crap. I've seen worse since then, but didn't get pictures.  You're supposed to clean this out, you know, once in a while.  My mower won't start. You JUST worked on it! It's WARRANTY!  Safety is job 7502803800729572394721.2  I need a "tune up". What do you MEAN it's going to cost $700?! Top oil seal and/or breather gasket + valve job and one new head due to the extreme overheating and dropped valve guide.  Once or twice a year i've got to go prepare this pile for scrap.  The best trailer ever. Of all time.

Gaskets always come apart when you pull the head. You can see a bad headgasket by white smoke coming out around the perimeter of the head. You'll also hear it "tsss, tsss, tssss" when the engine spins down. You would see carbon markings flowing through the gasket region had it been blown. What could have happened is that your ACR failed, or the valves are so worn the ACR does nothing. With the piston at TDC for ignition, try to wiggle and spin the valves and wiggle the piston, no play should be evident. Then have a buddy (or clamp) hold the bail and pull the engine medium speed. Look for the valves to open in an alternating fashion, and the exhaust valve to do a tiny second bump during compression. If no play and no bump, suspect ACR on camshaft.

As far as timing belt breakage being anyone else's fault, it's not. I am a service writer at a (lawnmower) shop that serves commercial customers for a major metropolitan area. Even if you buy our premium commercial tune up in the spring, you'll need to do a lot of the steps again by July and again in September. We're not going to give you a list of stuff to do, the hour meter is right next to the key switch. Don't bitch if your spindle bearings poo poo because you haven't greased them for 300 hours. You read your manual and you tell me. Or just pay the piper.

I don't refuse to believe Ford was incredibly lucky, it just seems unlikely. Getting loans just before there were no loans, having a large lineup of fuel efficient cars at just the right time? The mod engine sparkplug issue is hugely widespread. Acknowledging and repairing all of the affected heads would have ruined any company.

kastein posted:If you want something simple, look at a disc brake... a caliper with a piston pushes two pads together against the sides of a rotating disc. Doesn't get packed with mud or dirt, no adjustments, the pads are flat, and you can put an e-brake on it by milling an ACME thread into the piston and attaching a bellcrank and the e-brake cable (example: some Cadillac rear calipers.) Or put a brake band on the transmission output flange. Simplest brake ever.

I give no gently caress about another couple pounds of unsprung weight, I drive a live axle. Just... loving drums, man. Yeah, I can take them apart, rebuild everything cheaply and adjust them properly. But gently caress a bunch of that poo poo. I can "rebuild" my front brakes without even dismounting the calipers. Spin piston retraction bolt, remove pad retention pins, slide out old pads, slide in new, set new pins and release retraction bolt.

It showed up last week full of roofing materials (dump trailer) and the end of the axle missing the hub was tied up with many multiple ratchet straps. We made him go dump the load before we'd do any work to it. Pretty sure the axle is fuckered on that one, too.

I sanded most of the skin off the back of where the thumb joins the hand. Flap wheel went right through the fabric and foam in the Mechanix gloves. I was removing plasma slag from aluminum for some dude's armor. We had an assembly line going making tens of lames for a guy. So anyway, instead of sanding the slag, sand the edge you cut. It'll reduce the amount of metal holding on the slag and allow you to zip it off in one pass. And it gets your hand out of the plane.
