2 1/2 Hondas- An In-Depth Look At the Honda 3813

[@robingibson7503]

Got a 4518, 30 years old still running strong!!!!!

[@jamesguralski5156]

I'm getting a 3813 for 100 bucks! Hope it needs little tlc!

[@pathoffman6393]

Great video coverage on the honda 3813’s. I bought a 4514 in 1983 and still using it anytime the grass needs cutting. Also, I picked up a parts mower 15 years ago and now salvage anything needed from it like the deck, wheels, steering arm etc......it has a blown head casket & was still running at the time of purchase but blowing smoke like a skeeder sprayer.

[@greenridgegardens8269]

Thank you for making this video. I came across it as I was researching the 2 cylinder engine by Honda due to considering this engine as a swap in my 69' John Deere 140 H1 for the Kohler k321 that recently gave up!! Your video was very informative and inspiring. Thank you again!!

[@tbah9402]

How did you adapt the pto shaft? Planning on swapping one into a golf cart but cant find a clutch for a 25mm shaft

[@jp8jeta414]

great video love your Honda's, I have one however with no room in my garage I let it sit outside covered up the winter of 2022-23 and some lovely folks decided they needed my PTO and fan assembly so I am trying to find them, but so far not having any luck as of today 03 June 2023. take care eh!

[@maidenrulz73]

I bought one new in '88...it cuts every summer and blows snow every winter....never any issues....best tractor I've owned...and It defiantly doesn't sound like any other tractors

[@jfkanye5001]

Great video! Happened to pick up one of these just today! Unfortunately it doesn't have the deck. I heard you mention that you could use a John Deere deck. Any info or guidance in that regard?

[@DocSprocket]

@jfkanye5001 None, whatsoever. I never did it. I'm sorry. Been years since I filmed this and I've forgotten what I said- but I suspect that I meant that you probably could adapt a JD deck but it's definitely not going to be a bolt-on affair. For as incredibly well-built as these machines are, it seems like the decks were bad for rotting out.

[@krakenking1597]

Those are so cool, those guys over the pond sure know how to make good stuff.

[@8lazingSaddles]

I've owned one for 6 years and have had very few problems with it. They are exceptional machines as you've pointed out considering their age. I doubt there are many original (unrebuilt) examples of other brands from that era. BTW, I need to order a PTO belt and the only belts they show are 63-66 inches long. When looking at the installed original belt It looks a lot longer than that. Do you know what the legnth of the PTO belt it takes is?

[@barry7586]

Thx for all the info. Very informative

[@redneckbryon]

I had a Honda 3813 out of all of the tractors I've ever had it's the one I wish I could get back, despite its issues it was a fun tractor to drive. I could be wrong but I believe they had two hard fuel lines from factory, one main line the other I believe was an overflow. Personally when I had mine I was considering putting a Yanmar Diesel in a 2-3 cylinder that would be an interesting conversion.

[@DocSprocket]

Yes, the carb overflow (vent) goes to what I think might be a charcoal canister or similar evap devide, and then a (possibly vapor) return line from there. The Yanmar? Cool idea!

[@josiahperez384]

Hey I ended up getting on of those honda engines and I put it into a golf cart with a 5 speed harly Trans and a 9amp alternator

[@DocSprocket]

That sounds really cool! Have you got a link to pics or video? I'd like to see that!

[@michaelllewellyn7215]

Hi what is the rating of a standard Alternator as I am thinking of fitting a sprayer with a 4 Amp motor to one

[@Darwinpasta]

How's that for timely--I got one of these for free a couple weeks ago! I got the engine freed up and running on ether, just need to throw it back on and see if it'll run on gas. I like your clutch damper delete (and I'll probably copy it, my damper's seen better days). I like what you're looking at with the bigger engine. Before I got mine running I was starting to wonder how hard it could possibly be to mount up an old four-banger out of a Civic or something :D

[@mcarroll598]

I have 3 of these tractors as well. What excellent machines! Wish Honda would’ve put a low fuel light on the dash. Ran out of gas a couple times while mowing. Lol

[@ayp1938]

they have a fuel gauge under the seat

[@garlicbreadjenkins5780]

doc your intro reminds me of a show called 'How It's Made' your intro -- today on How It's Made -- Honda 3813 --

[@twiztedmowers2]

this helped alot for when I get mine from my buddies

[@tractorhead971]

That's weird. You put this on KZbin the exact same day I was driving around with a trailer gathering two of those exact same Hondas!

[@DocSprocket]

Nice!

[@rheaub2]

Mine is a 1986 model, got 'er new. Has never let me down. But it's gotten noisier over time. Any tips to improve the noise? Parts like a mufler are scarce. Thanks for sharing this vid, great clip.

[@libertyforamericanow]

I am a lawn mower mechanic. I just aquired one of these from a customer. I worked on it for him a few times in the past but he upgraded (actually down graded) to a new husqvarna. This thing is garaged kept with an original grass catcher. Very nice condition. Almost mint. What do you think its worth? I live in hernando County Florida if anyone is interested

[@DocSprocket]

That's SO hard to say. Values are regional- and I don't even mean by country or even state. Hell, something can be worth double, the next county over. Based on your description though- I'd put starting value at least as high as the cheapest new rider a place like Home Depot currently has to offer- and I'd even consider that to be a lowball. These machines hold a great resale value, and although not everyone knows what they are worth, there ARE people that do- and are willing to pay it.

[@TimTabb]

Honda big red 3 wheelers are sometimes shaft driven in the center, might be able to use that motor and drive shaft to rig up to three wheeler rear end and a lot less work besides making mounts and getting it to work. But hey, it's an idea! Lol

[@benjaminmartin8196]

Thanks for the in depth review. I just picked up a couple of these for free, previous owner said they run, i need a batt to try them out. Was planning on turning them into matching gokarts so i was a little disheartened around 14:50 . I'll probably replace the engines with different ones and keep the body / frame. Any suggestion as to what i can do to repurpose the gx360 engines? Generator or some other toy? Great vid.

[@benjaminmartin8196]

sorry, just one more question -- i mentioned i don't have batteries. is there any harm in jumping it and running without a battery for an extended period of time? thanks for any advice

[@jesusprado6394]

I just acquired a tractor like yours. After installing the starter and turned it on it's a smooth operation but I took off the oil dipstick and lots of blowby are present. Is this normal? Engine is very smooth.

[@fixitinthegrass6412]

I'm going to pick one of these up tomorrow... Been sitting a couple years any tips on getting it fired back up

[@DocSprocket]

If there's been gas in the carbs, you can pretty much count on them being gummed up hard. Now the fuel pumps are an electric diaphragm type, and I wouldn't be too shocked if the ethanol screwed them up too. All of this of course is in addition to the usual checking of the oil, coolant, etc.

[@rogertalley7944]

Actually you don't have to take all that out. Take the battery tray and relay mounting bracket out, take the bolts out of the plastic timing cover, take the motor mount bolts out on the left side as sitting on the machine. Front mount and rear. Take the back fenders off and seat,and you can get the shaft out by prying the engine up..

[@TheKurtTribute]

My three cylinder Honda Mini Truck seems to use some of the same parts! For sure at least the fuel pump.

[@DocSprocket]

GambleFabrications Neat! I'd love to see it!

Can a Honda 4213 deck directly fit on a 3813?

[@noahtalbott9523]

wow im definitely going to look for one

[@genedavis7238]

I have a chasis and rear end from the Honda as well as a decent deck

[@williamfisher4751]

I have a honda 3813. Ran good. All of a sudden it would not go forward, or reverse. Same as the red one in. the middle. the break pedal will not engage. How. say you?

[@DocSprocket]

I've had the damper stick before. Start there. Try detaching it completely, and see what happens. Note: If everything else is working properly, clutch engagement will be abrupt and you'll have to slip it like a normal clutch.

[@williamfisher4751]

I can't find the transmission clutch. Is it under the seat? It looks like some kinda shock is under there. Seen the disconnect on Frank. Don't think the same on one in the middle. Please Help

[@beardedmuddah90]

do u know how to tell the year of 3813?? I just picked one up today. and just wondering the year.

[@mattgrooms3298]

How do you think the Honda drive train will hold up in a pulling application? I had a plan to use the engine in a cub cadet frame but if the Honda will hold up there is no need for that.

[@DocSprocket]

I suspect it would do quite well.

[@mattgrooms3298]

+Sprocket's Garage I'll give it a try, have you ever slipped the clutch on yours?

[@francoreia8147]

Replace driveshaft with chaingear and add jackshaft gear as prefered

[@mowerbro4212]

How you think this would do for a tractor pull??? Strong tran motor an drive shafts??

[@DocSprocket]

Well... I guess that depends on the class you're competing in. If you're going against other lawn tractors, it would probably do pretty well.

[@mowerbro4212]

@@DocSprocket think it a open stock 1050lb class prolly like cubs an wheel horses sears tractors ... This Honda pretty close to set up as a garden tractor just lawn tractor size.

[@DocSprocket]

@@mowerbro4212 I don't think it has the weight to play with the big dogs. But, admittedly, I don't know shit about pulling.

[@renearellano3907]

Hi there! I found one up for sale but, it doesn’t go into gear. Is that a major issue? Thank you in advance for your advice

[@DocSprocket]

It could actually be pretty simple. There's a damper on the clutch mechanism, and sometimes they stick. I started a machine after it was parked up for a couple years, and the damper was stuck- so, it wouldn't grab a gear. If you check my other 3813 videos, I believe I show off the damper somewhere and explain how it works. I'm pretty sure one video shows how to delete it for proper and instant clutch engagement. I'm sure other things are possible, but that's the first place I'd look.

[@renearellano3907]

@@DocSprocket thank you very much!

[@DocSprocket]

@@renearellano3907 You're very welcome.

[@RockeyDAproductions]

you should cut the shaft, extend alittle, then offfset each and use sprockets to gear it up mr sprocket.

[@DocSprocket]

I thought of it. Two issues- 1)insufficient space to offset shafts enough. At minimum would need abou 4". 2)Those couplers that llok like u-joints are not actually u-joints, and likely would not tolerate very much misalignment. Solvable problems, but not quick and easy.

[@RockeyDAproductions]

what about having a second short shaft mounted next to cut big one with a total of 4 sprockets? that would probably be harder to mount but would keep everything lined up.

[@williamfisher4751]

I. have a 3813 It will not go forwards or backwards when I put it in gear. From what I can see, the belt looks ok. the break pedal I'am not sure about it does not go up/down freely. Please Help.

[@DocSprocket]

Belt doesn't matter, it's shaft drive. Look for a shock absorber looking thing near the front of the transmission/clutch. It might be stuck. Try disconnecting it.

[@williamfisher4751]

@@DocSprocket Where is the transmission/clutch located? I see something like that under the seat,

[@StupidEarthlings]

Omg dude. I got a honda 3810 and i thought something is wrong, as it takes all that time to start moving. Ima remove that damper..thanks.

I'd like to see the layout of the belt on the cutter deck........? Please and thanks.

[@DocSprocket]

Baba Abba Unfortunately, the only deck I had is long gone. I'm sorry I can't help you there.

[@LouCFur90]

Do you think one of those two cylinders could be crammed into a cub cadet? Narrow frame, wide frame?

[@DocSprocket]

Yep- as a matter of fact, I contemplated repowering my Cub Cadet 1000 with the 18hp shown in the vid.

[@LouCFur90]

That would be quite the unique machine. I searched around and I still can't find anyone who has done such repower. I can't speak for everyone, but i think that would be a really interesting build. Keep up the good content!

[@noahtalbott9523]

did they come out in the U.S. i never seen or heard of them

[@DocSprocket]

Absolutely. I have several American friends with them.

[@moonman6154]

are they set up to idle that fast?

[@darkside0914]

only one way that I know of to speed up a shaft driven rider, without cracking open the diff, i've seen it done on an old cub cadet, I think it was a CC, and that's to put in a chain drive, basically cut the shaft, have the engine side going to an input sprocket, run a chain to an output sprocket and the other half of the shaft connects to it, but you must be careful to be sure you shaft stays balanced and your connection points are welded straight.

[@DocSprocket]

I chewed on that for awhile. One of the issues is that you'd have to offset the driveshaft down or to the side, to make room for the sprockets.

[@darkside0914]

which would require a u joint or other flexible but strong coupler, I suppose you could also do it with a belt and pullys, but again you'd have to offset one or both sides of the drive shaft, it's been awhile, but I believe on the cub the builder used an automotive style cv off an atv or utv ,and left the shaft to the diff straight, but i'm not totally certain, it's been a few yrs since I saw it.

[@gizzyguzzi]

I just picked up a 3813. It runs, drives, mows and idles. But poorly. Smokes pretty heavily too. Black smoke. Hopefully fuel, not blowby the rings. Thanks for the rundown. I've wanted one of these for a long time. Now what have I gotten into?

[@DocSprocket]

Parts for these can be somewhat spendy and hard to find. Worth it for an amazing mower, though. If you're chuffing black smoke, the first place I'd look is the carburetor. It sounds like you're very rich. It's quite possible that the float has sunk or is sticking, or the needle and seat are dirty or damaged.
