What Performance Parts Fit The Duromax 18hp 440cc Engine

[@cbtjmp89]

These videos are awesome! Just bought this engine last week for our cart project. Thanks for making this video. 3yrs later and still helping folks like us 👍

[@Johnnyreengo]

Amsoil is definitely the king of oil. They won Project Farm’s oil competition.

[@RedBeardsGarage]

After a lot of testimonies and reviews I read I fully switched!

[@joshuawatford8006]

I switched about 3 years ago and haven't looked back. Amazing oils and everything.

[@justinsebesta1288]

​@RedBeardsGarage Hey I got a dyno cams p open cam for my block and the crank will not clear it no matter what What cams have you found to be the best fit

[@jamesanderson4880]

Thank you again for providing us with the info for the 440. I am always catching your builds and use this info in my own builds. Appreciate you all . Regards James

[@carsondalton929]

Could you do one going more in depth on the differences between the older models and the D shape pull start 440s?

[@nofishbait]

I would like to know also. I was told by someone at Duromax that the XP18HPE 440cc Engine newer design has upgraded rod and pulls 6k+ on stock internals. I called again to verify and was told by someone else that 3600 to 4000 RPM with stock internals.

[@jesseshelby4383]

You guys used the old school intro that I haven't seen in a while. Been with you guys since the beginning and love your content.

[@RedBeardsGarage]

Thank you for supporting us all these years man! It means a lot.

[@menayazzie7765]

Just when I thought I was done with honey-do's and hobby projects, I see everything that could be done to the 440 DuroMax. Well...my DuroMax has been sitting in storage for months and these upgrades are a good reason to bring it out.

[@kwatt-engineer796]

I really appreciate this Dmax440 video. I've got one in my current build. Nice info to have. Incidentally, your Talon impressed me so much I bought a 1000x I will make this one street legal. Thanks for all the informative videos.

[@ragemotorsports4727]

What was the outcome for HP now with the aftermarket parts?

[@Fukuimold]

[@jamesschenk1963]

Awesome video as usual very thorough description of all the content have a great day

[@WoLFSkYBLuE69]

Another great video dude.

[@clappincheeks5584]

Definitely going to have to do this to my duromax

[@snb1340]

I bought a new 440 with the D shaped starter. Definitely a 7 bolt side cover. Hopefully the guts and flywheel I will order will be the same as you show. I'm getting the 6623 ( I mounted a alternator) the 6272 rod. The 7 bolt cover is a 6059 the 10 bolt is a 6060. I believe the head gasket is a DJ-4610T which is a thick gasket. Thinner gasket is a MLS92-027.

[@KobeGriffin]

did that 6623 flywheel end up fitting right? or have you not ordered yet, iwas lookin at the same flywheel, and the .308 cam

[@austmurr]

​@KobeGriffin I contacted duromax and they said the only change is the recoil start cover that changed.

[@kenjohnson5498]

What about milling the mounting surface on the starter itself to give more depth to the gear? Then your fix isn't in spinning components. Not sure if it can be done but I will always have thought it could be lol

[@SeanStratton-ql1sf]

[@trumpfancardanostakepool4737]

Great quality vid as always. Small engine master.

[@jj1252]

Did you ever end up releasing the ring gear spacer?

[@Parents_of_Twins]

You should use a micrometer to measure the crankshaft. The difference is knowing for sure that when you measure 1.416" that you have 1.416" plus or minus a half thousandth versus plus or minus a couple thousandth of an inch. For most of your builds it probably doesn't matter but when trying to get an engine to go all out it could make a difference. Personally I buy a lot of my measuring tools used to help lower the costs.

[@henzoemckoy805]

Greatings big boss. am a farm work from Jamaica working in the US and am going to build a walking tractor but am in two opinion with one of these enging predator 459 r duro max440 ? the Lord bless u🙏

[@josephbedenbaugh7243]

Can you add a link to the starter ring gear, didnt see it in the description. Also great content as always.

[@daveoftennessee5535]

ARC sells the flywheel and ring gear as a kit and it looks like it comes with spacers to put between the two to get the right starter engagement

[@shrugger1]

I'd be interested to see what it'd take to put this into a Trailmaster Hurricane

[@milesmac00]

FYI The 440 that shows in your link from Amazon is a different engine than shown in the video. The block casting and covers differ, and the side cover is 7 bolt. Possibly different mfg, or updated design? (The Amazon photo is the same, the actual engine shipped is different)

[@troysmoliak4924]

Red beer I'm a big fan of your show best little confusing jumping one from one thing to another?

[@savian1973]

Quick question Red Beard can you please also let the viewers know if a stub shaft of some sort can fit on the flywheel side of these motors and where you may find them and part number if possible? Love the videos.

[@joewalton2726]

What about charging for the battery and any lights? How do you make that work?

[@douglasballentine7792]

So glad you did this video. I just put one on my sons Manco 616 with a 40 series torque converter and I love that thing. Right now I’m trying to figure out how to replace the back wheels on it with the hex design. Do you think I should just change out the hex axle for a 1” cylinder axle? Thanks again for all your videos helping us out!!!

[@RedBeardsGarage]

Yes, swap it for the 1".

[@IsAmericaforSaletoChina]

3:10 those stud bolts. Mine got hit with a hammer by an angry old man. Where do I buy more stud bolts for this?

[@snb1340]

And thank you for being a great teacher. God Bless.

[@nikdipetta]

So glad you did this video. Had my 440 waiting in the wings for this video and information. Any chance you know the flat top piston part number or who sells it?

[@TheJojoe88]

Did u ever get a piston part number?

[@nikdipetta]

@@TheJojoe88 I did. I’d have to look. But I def got it from studz racing. 460 piston 92mm think it was $45

[@dwilson15951]

Where can you still buy one of these old style engines? All I can find are the 7 bolt side cover ones with the D-shaped pull start. What is compatible between the old ones and the new ones?

[@MachinesWithDavid]

Important question, how can I get the starter ring gear? I can’t find it on the website and it did not come with my billet flywheel :(

[@yay4this]

i ordered the magnetic dipstick in your description and it too fat to thread into the oil bung. 😕

[@RedBeardsGarage]

Please email what engine you are trying to use it on. [e-mail]

Thanks for the videos and Thanks for your time

[@duaneheadworth6275]

I have a Hammerhead T80 go cart and need to swap out the engine. What engine should I choose for performance, the HF 224cc or the Ghost 212cc? Thanks you for your time. I enjoy your channel.

[@BackFortyTV]

What do you think was the total cost to upgrade like this? Have a 440 on a mud motor and want to crank her up.

[@brianwinters8454]

Any idea when where I could get the spacer for the starter ring?

[@LAOutdoorReviews]

What’s the best way to get more charging from a 440? I have seen an 18 amp Honda 4 post charging coil that I don’t know if it really puts it out. It was $150 plus the needed flywheel with 4 magnets was about $50. Or would putting a alternator pulley on the end of my comet 780 be a better option?

[@kevintangen5769]

Is there any difference between the 10 bolt side cover vs 7 besides the obvious

[@bigbaby1177]

I giggle most every time the way you say you say O I L. ;)> Was trying to remember the other word you said and then you reminded me when you started talking about the COIL.. Thanks for this video, I hope to someday put it to use.

[@RedBeardsGarage]

😁

[@troygibson6800]

What flat top piston would you use? I would like to bump up the compression.

[@SportbikerNZ]

How many different types of flat tops are there? If there are many options it'd just depend on how much you want to increase compression.

[@redneckgarage1167]

I would love to see this engine on a trailmaster

[@pauledwards4822]

I find your videos entertaining and informative.But a question is how do you put on a performance Carburetor and keep the choke.Doesn't it come off with the housing , sir

[@toolman9081]

Be cool if we could keep the generator system with the aluminum flywheel.

[@racsoednamzug5446]

I bought 18HP duro-max 440cc non electric start which I am converting it to electric start. I've ordered already the starter and the electric switch ass'y, which I have a project to put it on a small boat. I want to buy a billet flywheel plus the flywheel ring gear and the insert that you are talking about in your video. I just want to know how much it will going to cost me. Thanks!

[@mitchnelsonperformance]

Thanks for the video👌 Do these parts also work on the newer style 440cc duromax with the 7 bolt side cover?

[@kourtneyltd67dombroski78]

I have been waiting for this video now I can get to spending the money 🤑🤑

[@stephenagaertner]

i have a 439cc Duramax motor from a campion type of generator. It has a "very short power output shaft" that fits into the generator stator parts. Is there a different crankshaft available that I can I replace it with in order to bolt it to a 40 series torque converter?

[@RC_Trailblazers]

Where's the link for a starter ring gear on the flywheel. GPS only shows the flywheel. I would like to keep the starter.

[@howardleadley4775]

Greg have fuel issues with engine swap to a 2009 Yamaha, installed DuroMax 18 hp engine and 2 to 5 pound electric fuel pump because fuel tank low fuel sucks air and starves for gas now fuel by passes needle and seat with stock carb, ideas?? has stock carb.

[@HappyHands.]

you probably should of debured the edges of the shaft key slot before pre-fitting the aluminum flywheel. you took a lot of material off that flywheel.

[@MachinesWithDavid]

Please I need help finding the retainers for this engine! I’ve been stuck for a couple months due to searching, I lost 1 of the tiny little retainer pieces😢

[@TheSharrd]

Hello great videos,can you please tell me what size carb jets to get for intake and header upgrade on stock carb,starts good then falls on its face , won't rev ,popping thanks

[@FlynVOutfttrsNGundogs-Jordy]

I have one of these on my surface drive. Wondering if I could drill a hole in the valve cover and use a fuel pump to run a bigger fuel tank or if you'd recommend running a carb with a vacuum line instead? Also would like to upgrade the charging system as it is electric start and I run LED lights on my boat so it would be nice to run at least the small ones that way

[@dsheffield2010]

What is the highest performance upgrade you would do to a stock 390 while retaining the charging system

[@nitewatch2.027]

Are there recharging coils for these? On the flywheel,, couldn’t the ring gear be milled out to fit around and be welded to the flywheel?

[@bernieglass8098]

Would like to know what size magnetic dipstick I can use. Would it be 18m×2.5 ?

[@trkyhntr8685]

Can you please do a video installing a stage 1 on the 440 please?

[@lanenelson5517]

I saw in one of your older videos on the 440 you stuck with the stock piston. Do you think it is necessary to use an aftermarket one and if so, which do you recommend?

[@baldtireproductions1281]

do you build these for mud boat motors the record is 64mph i feel like this 18 horse built right could get you going 45 to 50 on the water i havent seen one built yet but it makes a big diffrence in these carts

[@joemann5730]

What was the total cost of this build? if you dont mind me asking

[@reopetallar2422]

Hi! I'm a fan. I just want to ask if the RPM of it are the same in land and in water?

What performance parts fit the newer one? Thanks Greg.

DO A VIDEO ON THE NEW PREDATOR 459 I WANTED TO KNOW IF ALL THE PERFORMANCE PARTS FOR THE PREDATOR 420 WILL FIT THE 459 ESPECIALLY AN UPGRADED CARBURETOR

[@RedBeardsGarage]

The only parts that fit it is the cam, carb, and exhaust. The rod and flywheel are different and I don't think no one is going to make parts for it. I will make a video in the next couple of days on it though.

I just purchased the DuroMax 18 hp 440cc. Did they make 2 different Block versions? Mine only has 7 Bolts holding the cover on? Update: So after some research it appears the XP18HPX uses a 7 bolt side cover. I ordered the XP18HPE. The box that the engine came in says its what I ordered but the block says a different story. Anybody know of any other way to tell the difference?

The Duromax 440 on Duromax Website they show only 7 bolts on the side cover. Amazon has pictures of it showing 10. Pretty sure the model numbers were the same. Just want to be sure they still make the stronger side cover and they aren't cheaping out. I know the wildcat 460 is 10 bolt but flywheels won't work. Anyone know for sure?

I have a duromax with the D shaped pill start but I'd imagine at the least the 34mm carburetor would fit. What's the difference between the ones with the D shaped pill start and the round pull start?
