The Cub Cadet 782 Lives! Onan P218G Engine - First Start in 13+ Years

- The moment of truth! It only took me 5 months of wrenching (whenever I could find time), but I finally got the Onan P218G engine ready to mount and run in the Cub Cadet 782. In this video, you'll see the old Onan come to life after sitting idle for more than 13 years. That's not an exaggeration either; this engine was pulled out of a John Deere 318 back in 2005 right after the previous owner put a brand new carburetor on it. I have the original Onan box that the carb came in, and it has a 2005 manufacture date on the label.
Since the last update video, I installed a new wiring harness in the 782 (it's for an earlier IH-built 782, so it doesn't have the neutral safety or reverse PTO relays built in). Also replaced the key switch and fuses. I found all the missing engine tins needed in order to bolt the 982 muffler shrouds up. But the tins were either rusty or had mismatched black paint, so I dropped all the tins off at a local powdercoating shop to get sandblasted and coated in satin black. I also had to replace the cheap eBay starter with a higher-quality starter because the eBay one didn't have enough power to crank the engine over, even with a full 12 volts from the battery.
I got the new starter and engine tins installed, and mounted the P218G engine in the tractor once again. Hooked up the driveshaft and tightened all the CV joint screws, wired up the coil and regulator, installed the fuel tank with new shutoff valve and fuel lines, replaced the air filter & spark plugs, and changed the engine oil to Rotella 15w40 diesel oil (my go-to for opposed-twin engines). Also changed the oil filter and installed a new filter grommet (to keep the engine from losing any cooling air around the oil filter hole).
I primed the carb and checked to make sure the fuel pump worked. Turned the key, and.....I'll let the video tell the rest of the story! Once I get a few more hours of run-time on the tractor, I will start piecing it back together. It's going to be a very tough worker when I'm finished with it...planning to add power steering, dual brakes, three-point hitch, and lots of other accessories down the road. - ยานยนต์และพาหนะ
Opposite engines always sound so good.
Sounds great 👍 you brought it back to life
That's so cool man awesome job can't wait to see it all back together and put to work again!
Thanks Tyler! I'm eager to put it back together, but I have to check for leaks and any other issues first. Shouldn't be too much longer before it's ready to work.
I anticipate this tractor all fixed up and restored, I wish you luck on restoring this beast
Thanks. I'm doing a mechanical restore but not cosmetic...the original paint still shines like new. It's going to take a few years to get this tractor where I want it, but I'm going to build it into a really tough plow day and mowing tractor.
@@MichaelTJD60 it sounds like solid machine for both those jobs
@@iowansirenrecordings2454 Power steering, super steer axle, rear axle braces, three point hitch, LED lights, and dual brake pedals are all on the list.
luv to hear " the engine is good to go" ~~~~~ Thanks for posting! COOOL VID! and luv that Onan rev(powerful little buggers)
Couldn’t sound any better! Now, to see her together. Lol.
Looking and sounding great! Now it’s time to put the rest of it back together.
Thanks! I should have it back together real soon once I'm certain there are no leaks.
Runs & sounds great. Good job!
Thanks!
Way to go man! Love the Onan, best sound ever
Thanks! It's one of my favorite sounding engines for sure.
Nice job! I got a Lawn Chief by MTD once and got it running. I towed my full size Bronco around the yard with that mower before I rebuilt the mower deck. That mower lasted me 3 years before we sold it. (Couldn't take it with us in a move. I sure miss that mower!)
8:01 little guy shoots flames!
Music to my ears ! I grew up 1/2 mile from the Fridley Onan plant ! My dads best friend was the lead architect small engine department till he retired back in 1990 ! Real close to home !
Very cool!
Love that sound! I have a Lincoln welder I picked up, that’s from the mid 1990’s and she sounds awesome with the Onan power!
I'd love to have an Onan-powered welder! The Onan's on welders and generators run forever because they don't see as much abuse as the ones in tractors.
Remember me from MTF? I like the sound of this thing!
Long live the onans! I got 2 wheel horses with onans and I'm redoing a work horse that had a briggs for an onan and upgraded rear axle. Looks like it belongs in that cub!
I wouldn't mind having an Onan-powered Wheel Horse someday. I really like the 520-H but they seem to bring big money around here.
Onan power lives again not the junk repowers people think is worth 2k
Nothing like the sound of an Onan firing up. That thing sounds good
Thanks!
IT SPITS FLAMES 🔥
love then onans, Super videos
Cool. I can't wait to get my little Kohler running that thing hasn't ran in 25 years
That will be exciting. The K series are really tough engines and will probably run on 25 year old gas.
Somebody was smart before they parked it and drained all the gas out
Great job....Well done!
Thanks!
very nice job.
Looks great. I would have happily painted it for you.
Great job But i have one question where is the fuel pump getting it paulse to run it. I have had 3 opposed twin Biggs And there mounted to the carb. thanks Keep up the great work.
It has a vacuum line coming off the timing cover which is behind the flywheel. The line comes out to a hole in the flywheel/blower shroud and connects to the fuel pump, which is attached to the shroud.
When you getting the engine decals and put then onans it sure dose sound good and when is that thing going to be mowing lol good video.
As soon as I get the PTO issue figured out lol. I probably won't be getting the engine decal made until later on.
@@MichaelTJD60 yea it be a nice one to mow I'm now working on my frist mowing videos and I have videos of the la105 to get posted
My cub cadet has a freakin Kawasaki on it.. The starter is 300.00...wow..sounds like a VW.
Can't wait to see it finished good job better use a good oil Cheers 🍻🍻🍻🇺🇸🇺🇸
Kawasaki's are great engines as far as the newer machines go. The hefty price tag for parts kinda sucks, but at least you're paying for good quality. The same goes for these Onan engines....people turn away from them because parts are expensive, but at least you know the parts will be good for another 30 years.
Can you onan swap a gear drive, cub cadet vs the hydrostatic or will the clutch not work properly. I have a 1050 and i kind of want to get rid of the M10 (it runs really good,no smoke or anything) a twin or 3cylinder kabota in it but im not sure how i could make the clutch work or the mule drige work
I have heard of a couple guys running Onans in their 1050 pullers. You will need to use the engine mounting plate from a twin-cylinder model like a 682/782/1811 etc, and will need to make a custom clutch driver disk to fit the Onan flywheel since the bolt pattern is different from the Kohler.
Nice repower, just gonna warn you the side panel on the oil filter side may be hard to put on. Had a p224 in a 82 puller and I couldn't use the engine side shields cause the side panel hit.
Yeah this one is a really tight fit. The 13-year-old oil filter was about 1/2" longer than an OEM one, and it stuck out just far enough that I couldn't fit the side panel on. But I put an OEM-sized filter on it when I changed the oil.
I like the sound of a Onan
Me too!
@@MichaelTJD60 my neighbor had a Cub Cadet 1810 hydro with a Onan and I loved it, I would go out side and watch him mow and plow and 2 years ago it started to sound rough and it blew dark smoke and didn't run smoothly on high throttle. Then one day he was mowing his back yard and the tractor sounded like a gun shot and fire came out of the exhaust and I never saw it again. I miss it so much...
@@ericfreeze1945 You sure it wasn't a Kohler Magnum 18? That's what the early 18XX series Cub Cadets came with. They are good engines, but in my opinion not quite as good as the Onan twins of the same era. I had an 1811 with a Magnum 18 that ran decent after I replaced the carb and fixed a couple fuel delivery issues.
It was probably put in from the old owner because he got it in 05 when his old mower rusted out
And thare was no side panels and a strip of diamond plate under the logos on the hood
yea sound nice its important to finds a good starter my kohler magnum 18 cranks hard any ideas the batter said 12.52 volts and a charged battery is 12.6 volts so its possible the connections arent good or it needs a valve job but it floods any suggestions
Battery should be putting out 13.6 volts minimum. I'd start there.
MichaelTJD60 ok thanks
Was the Onan an option on those, or is it a repower. My old girl is a 1968 Cub, but with the single cylinder Kohler.
Repower. 782's had the Kohler KT17 from the factory, and 982's had the Onan B48G. But they all use the same sheet metal and engine mount plate, so the Onan bolted right in place of the blown-up Kohler.
@@MichaelTJD60 Nice!
WHO was stupid enough to give this video a dislike!?!?!? Seriously, somebody did. What,s not to like about watching an engine start for the first time in years??? As far as I can see, nothing.
Either someone who hates Cub Cadets, Onans, or someone who expected another truck video, I guess.
@@MichaelTJD60 well, I suppose it does make sense
Wow, Hard work pays off!!!! Sounds like you need a new battery or check your cable gauge
The battery was new in November but it's only a 300CCA so I'm going to try and find one with more cranking amps. The ground cable on the battery is a new OEM 782 cable.
Wow!! Im shocked, my 87 318 ran a 230 cca and it could crank forever and that was a cheap husky that was like 3 years old.
Yeah thats definitely the battery. Sometimes these new square tops are great and the other one last 4 months.
Yeah I'm surprised too...I've had great luck with Deka batteries, but I guess these cheaper $45 lawn tractor batteries just aren't that good.
I run car batteries in most of my tractors but the battery tray in this one isn't big enough to fit a car battery.
Does this carburetor flood just curious my Kohler magnum floods I don’t know what to do it had a professional rebuild cleaned new needle and seat I do not know if the float was changed or not do you think an after market would fix it it’s a hassle to turn the gas off I’m not that lazy I just want to make it perfect and sometimes I guess it gets the best of me
You sure the float doesn't have a small hole in it? I have heard of that happening with the Kohler twins before. The Onan's don't usually flood but they are always difficult to start when warm because of how the intake and exhaust manifolds are routed - the gas usually boils off inside the carb from the exhaust heat.
I have an Onan p220G and a cubcadet 1811 that needs a new motor. Think it would swap over easy?
Not exactly. You'd have to swap the oil pan and starter with the ones from a B43G or B48G engine, and you'dhave to swap out the key switch with a regular 5-prong switch (no kill wire). The driveshaft also would not line up using the original pieces for the Kohler engine. You'd need to find the drive hub and pilot bushing for a 982, which are not easy to find. For that reason, I ditched the original driveshaft and had to use a custom-built driveshaft out of an 1862 in this tractor.
@@MichaelTJD60 thanks, i'll just rebuild the m18 then.
What's the thickness of that aluminum driveshaft adapter?
The piece bolted to the flywheel is about 1/2" thick if I remember correctly.
She sounds great Michael, just wondering, did you get that new carb from Isavetractors?
Thanks Andy. It's an OEM Onan carb that the previous owner installed when the engine was pulled 13 years ago.
Everyone seems to have good things to say about IST carburetors, and their Onan carbs are pretty new, so I'm curious to see what kind of reviews they get. If they work good, it would be great not having to pay $250 for an Onan-brand carb.
MichaelTJD60 I might try one on my 79 19.9, I think the carb needs rebuilt, but a new carb should be even better. Hopefully.
@@shiftinggears6859 Yeah you could always rebuild the old carb and keep it as a spare.
is that your shop its really nice
It's at my school. I wish I had my own shop that nice.
I like my Onan engines, to bad parts are getting so expensive.
Yeah it's unfortunate, but I'd much rather pay the price for OEM parts instead of cheap aftermarket parts that won't last...like the starter I had to replace.
Is this the Onan engine that "Mustie1" says parts are no longer available for?
Yes. This P218 came out of a 1987 John Deere 318, which is pretty much the same tractor he is working on. He must not have done a lot of research, I can name at least 4 reputable Onan parts dealers. Parts for the earlier Onan engines from the 60's and 70's might not be as easy to find.
@@MichaelTJD60 I misquoted him. What he said is this design was sold to another company and the parts are still available but are very expensive. He mentioned an overhaul gasket set from them is over $200, although some aftermarket suppliers are much cheaper.
@@robj2704 Ah, yes that is more accurate. Onan was getting in trouble with the EPA in the 90's because they could not meet emissions laws in the US, so they sold production rights and tooling to the Linamar corporation in Canada, who continued building them until around 2003. They were pretty much the same exact engine with a different name badge. $150-200 is about accurate for a full gasket set.
Which is better, the 318 or the 400?
318 by a mile. I've been around a few 400's and have no desire to own or work on one. The only thing the 400's have going for them is they are big and heavy.
Onan engines are super overbuilt i took that same engine off a 4.0 bfa and a 6.5 nh super reliable, even after being in a low grade fire the engine parts were fine.
That's one of the reasons why they are my favorite engine. The internals are much stronger and are designed so they don't cause catastrophic failure when something lets go. They can be rebuilt several times over.
Occasionally my pump is loud, it's a 2000hr 1440 so what else can I expect? Haha
All hydro's whine regardless of hours or age. I'm just surprised this one was so quiet.
@@MichaelTJD60 they're terrible when cold😂
Garden Tractor Kings it’s forcing oil through a hole and it’s thick so it’s gonna moan that’s why I let my
Hydros warm up first so it gets thin and flows easy
I wouldn’t adjust the carb until ya get the exhaust completely installed buddy that has a large effect on air fuel mixture do to back pressure ,, i know you probably already know this ,, just thought id mention it anyway..and are ya gonna use this for plow day ?
You are right. I've been running it with the mufflers on lately, but I can't bolt them down until the PTO is mounted and adjusted. Yes it will be a plow day tractor but not until next year...still need to get a 3-point hitch, ag tires, and a few other accessories.
I hope that key doesn’t fly off.
Surprisingly, it didn't. I forgot to remove it before I started the engine.
Aren't these Onan engines nicknamed "the sidewinder" ???
Never heard that one before, but since they are horizontally opposed, I guess the name fits.
@@MichaelTJD60 A dear late friend of mine told me they were known as the sidewinder. About 7 yrs ago, some fella gave me an old Cub Cadet. I can't remember if it was the same size tractor as this one, or perhaps slightly bigger, but it did have the Onan engine. ( Again, can't recall the engine size. ) He told me all it needed was rear tires & carb work. Had the plow, box blade & another attachment that I can't remember. The mower deck had 3 blades & I believe it was a 52" cut. Does that sound right? I know it was close to that. Anyway, I sold it to my late friend for $250.......only because he fell in love with it immediately, and I knew I may never get it running, lol. I knew nothing about Onan's at that time. Sure enough, he fixed it, and it ran great. When I pulled into his driveway, he was using it to "bush hog" the vacant 1.5 acre lot next door. He already had half of it mowed down & was still going. I swear, it was nothing but mostly thick, dense rag weeds & other weed waist to chest high, with many of the weed stems about an inch or more in diameter. He had that thing in 3rd gear I think, and that tractor was slinging those weeds 20 feet, lol. That motor was humming along just fine, not smoking, bogging, or sputtering at all. I had to jog to catch up to him, I kid you not, lol !!! Needless to say, I was very impressed. He used it for about 2 years & sold it for $1200. That was my introduction to the famed Onan "sidewinder". My late friend told me the Onan is one of the best gasoline engines ever made for small tractors.
@@howabouthetruth2157 He was certainly right about that! The Onan's are my favorite small engines, they produce a lot of torque and are hard to kill (with proper maintenance of course). It's a shame parts are expensive for them, but they will outlast (and out-torque) a lot of other small engines in their class.
@@MichaelTJD60 Parts being priced very high for these doesn't surprise me. I guess we get what we pay for. Take care.
Just wheel Horse with onan p218
Not running
Wow that thing looks so mint!
It'll look like new once I get the sheet metal on. The original paint is in really nice shape.
Good grief isn't not green like your videos
No but it has the heart from a green tractor. I'm building this 782 to be like a JD 318.
Keep the muffler off!
Don't need to burn up my exhaust valves lol
all that to spin a washer
wow after looking at your reviews, i realize i should watch it. beauty, eh.
@@rabaloo6549 Lol. Thanks for watching.
You need to get Instagram or something
I've thought about it, but TH-cam and Facebook are already enough of a distraction.
