Predator 420cc Oil Cooler & Filter Install
Вставка
- Опубліковано 1 сер 2021
- Today we experiment with a Harbor Freight Predator 420cc Engine. We show how to install an oil filter, oil cooler, and oil pump. We saw 30-40 degrees difference on the temp of the oil. With the added filtered oil this can extend the life of your go kart or mini bike engine and help make more power. We will be putting this on a 150cc go kart. Check the links out below.

Need to return oil threw the governor hole once removed then it'll be dumping the cooler oil over the moving parts instead of pushing threw the hot crankcase oil
Great idea.Thanks.
Not a great idea if you're running at high rpm. The power loss from windage would be pretty significant.
You can put a oiler tube into the crankcase bent to wherever you want if your that worried about windage lol. Like oilers on diesel engines
Return the oil through the valve cover to cool the head.
@@davidzelinski1868 perfect idea.
Keep in mind that all of these air cooled engines are running less than 100 degrees from total failure. Every degree you remove helps with performance and longevity.
Great idea! The only thing I'd change is to find a way to mount the filter vertically so there's not a mess when changing filters.
One small step for honda clone engines; One giant leap for reliability. Well done Red Beard. 👍
Pretty cool! “ Keep a ton of hose…” and an engineering degree from “Harbor Freight” was a legit LOL!!! 😂
I have already done this i added a oil pump and oil cooler and oil resivour to my Generator i also wrapped my long muffler with 2 1/2' inch aluminum tubing with brass fittings i pump antifreeze thru one hose and send it to a external heater core with 3 speed fan 12 volt ⚡️ dc the other aluminum tube. I Pump FRESH WATER 💧 through this one and it heats water up in my water heater . It curculates water 💧 in my tank heating up my water tank , for hot 🔥 water to use for bathing or washing dishes or washing machine for clean clothes , i also use my generator to charge 3 AGM Battrys 150 amp hour battrys giving me 450 amp hours of DC current at 12 volts ⚡️ DC for my 3000 watt ac inverter. I controll everything with a marine generator controller.
Just rode my Coleman trail bike you sent me back in 2018, still goin strong! Love the vids, keep it up!
If you run the oil back in the valve cover it would help cool the head and lube the valve train
I was thinking the same thing.
I've always wanted to do this, didn't know where or how to start, YOU paved the way. Thank you 😁
Absolutely love the in depth motor work and info. Keep it up man
"Did they cross-thread all of them? Yes they did..." 😂😂 Been looking to do this on a long-run generator. Thanks!
For most inferred temp guns, you have to hold the gun 1-3 inches away from what ever you are measuring for the most accurate results. I have to use them in the oil refinery I work at, and it does make difference between holding them a foot away and an inch away from whatever it is you’re temp checking. Awesome video once again👌🏼👍🏼👍🏼👍🏼
Instead of the oil cooler you could also have an external oil tank. This would increase the total volume and heat capacity of the oil.
I mean the whole system adds 1/2 a court of oil already
That's really good idea
Except it wouldn't add any active cooling, just a longer delay in rising oil temps from the larger thermal mass of the increased oil.
@@SportbikerNZ you put heat sinks on the external oil reservoir
@@midnightwaterdragon4725 You could. Still a distant second option to an oil cooler.
Those engines are more than enough to thrash around and have fun. Thanks for the video awesome mod.
Can't wait to watch tomorrow night!
Hi Red!: Thank you for your great videos + dedicated work on these small engines with a lot of potential to improve basic factory features;
>How about installing the cooled + filtered oil (At least, part of it..), thru the valve cover to do perform a couple functions:
>Lube + cool the valve train.
>Cool the head itself
*The rest of the cooled + filtered oil, to be returned thru the governor hole, thru a copper or brass tubing (Could even add a small nozzle..), to squirt oil to the mechanical moving parts, probably including the piston skirt iself + cylinder wall.
*I'd also keep in mind the positive pressure built inside crank case to partially help the above circuit.
>Bottom line is a cooler working engine should be a longer lasting one. Of course the oil pump itself should be strong enough to fully keep moving the cooled + filterd oil, and overcome the crank case pressure..
(Just my two cents)😢
Nice! I can’t wait to see how the alternator turns out.
I have always liked these Predator engines and to see the mods and upgrades you do, makes me want to sell a few other toys and go start a buggie project. Keep the videos coming! -Lee, Gainesville, GA
Glad you like them!
8:00
I have a stage 1 predator 420 that has issues with the battery not being able to properly charge. I’ve seen the video on how to put better charging coils but I’d definitely like to see a video on how to Setup an alternator! Thanks :)
That's pretty cool I wouldn't mind having an oil filter and cooler on my power washer and Generator that sucker runs 8 hours a day
I'm thinking about doing this for the transmission in my wife's suburban. Thanks for the parts info.
A couple of benefits, longer service between oil changes and considering these motors hold very little oil this set up should almost double your oil capacity.
Cool. I remember doing it about 3 years ago and it worked great. Looking good
I have had the oil pump idea for a long time thanks for testing it out. Keep up the good work. Brent Hazen Glendale Az.
excelent idea the only thing I would do is return the oil on top of the crank cass so the oil will splash off the crankshaft and add a lot of lubrecation to the engine. thanks keep up the good work. Brent Hazen Glendale Az.
Another great R.B.G vidd... this is a great set up for my model #310 bobcat. Plus I have room for it.. my harbor freight motor doesn't getta Lotta cooling besides what it produces from itself.. all air cooled motors need as much cooling as possible .great vid R.B... looking forward to the alternator vidd. I
Luvv these How 2 mod viddz👍👍👍👍
this is great. giving me Ideas for my duromax 440 IRS vortex build. cant wait to see the alternator install.
I like the idea & the execution of this project. I believe the temperature difference would have been more dramatic if both engine were run with a load on each engine. Temps. would have been higher & the cooler would make even more difference. Great project & I look fwd. to the Alternator install.
19:49 Couldnt agree more, I love these sort of projects
Put the oil return line through the valve cover on the head and really have an impact on the cooling capability
That "hose" joke was on point! Had me laughing 🤣
I’m excited for this build
Will be great on the new 459cc pressurized oil system .
16:03 man! i like that new gas powered folding table!
Man I love this. Completely unique.
All I can say is, its beautiful sir! I love it.
Now I want to revamp my Duromax generator. cool experiment.
I'm thinking about doing this for my 459cc predator generator and was wondering if the pump has held up well. It doesn't need to move a huge amount of oil but it's a gas/diesel pump, not designed for thicker and hot oil. The good part is that if it stops working the engine would just be back to operating like it was, pretty safe! I really appreciate this video!
Good job with that setup. If nothing else you have the ability to have a pre/post oiler for those all-day hoon sessions. I think the cases being the same temp on both engines is a result of them being designed as a heat sink from the factory and wicking heat from the cylinder. I bet if you got a temp probe you'd prove yourself right on the lower oil temp, which is the more important factor and might let you run a lighter weight oil and give you a little more power. Also if there was a way to dump the return oil out on the exhaust side of the head but still flow back to the sump quick enough, I bet you'd also pick up some power there too. A piston squirter on the return might also do the same.
Old video but I watched it and wondered if you could use the oil level wiring fitting as the return hole and make it more of an oil squirter system aimed at the bottom of the piston.
would probably require a higher pressure pump
It's definitely a good idea to have the oil filter I did the same idea on my off-road tractor it had the 440 Duramax I use the drain plug for the pickup I didn't buy that nice pin I just drilled the hole at the middle of the tube to it and then head of it going through the pump through a radiator and then I went back into the valve cover it worked all right it's just over time because I had no filter everyone the pump
You’d definitely see a major difference in cooling with a larger oil cooler and strong fan
Just the added oil volume will help keep the engine cooler. The filter and oil cooler will probably make a bigger difference under load.
You should build and produce your own alternator kits, I'd bet you would make a killing on them!
Very cool. Love this project.
The drain plug is 3/8 npt threads and home depot lowes any hardware store sells 3/8npt to a hose barb adapter
Fyi
Thanks Greg!! Good stuff.
Outstanding job!!
Greg, nice video! 🤘🏻🤘🏻👍👍
Iv been waiting for someone to do this for some time a electric fan with thermostat would be sweet 👍👌✌️💯🥂🏍️
Very cool man way to think outside the box
I need this for my mud motor in the water
Should be fun changing the filter
I liked the build, and love putting oil coolers on engines to make them run cooler. I wonder how a counter flow cooler would work (liquid/liquid) and have water cooled oil. As a HVACR guy/instructor at the state trade school, I love to do experiments and ask these questions.
Is there enough space in the crankcase to run a loop of copper connected to an external radiator? I very much am interested in trying a liquid cooler or oil cooler on a 224, I have Honda Odyssey 250 that was modified with a liquid cooled head, it worked very well on convection flow.
Starting to look like taryl’s fuel test lol, this is awesome!!!!!
I just bought an oil cooler and filter setup for my GY6. I'm excited to see this install as I imagine it will be pretty similar.
Don't do it!!!! The gy6 Does NOT have a *pressure pump* , do yourself a favor and send the cooler/filter back to wherever you bought it . You're definitely gonna blow up the engine.
@@midixiewrecked7011 Yeah, I'll do that.
Cant wait until the alternator video! I have learned a lot watching your stuff! Can you address weather you are going to change up the charging coil like the "lifan video" or will it make a different. Thanks in advance
This was great info 🤜🤛
How do you check level? will that check valve hold back bleed back? i mean its a vented system at the crank so i'd worry about bleed back "over filling" the crank case. Great setup
This is bad ass bro!!!! Love it
I wonder about the efficacy of using a fuel filter for oil. Wouldn't it restrict flow with oil's higher viscosity? Causing pump to burn out faster? What oil did you use? Straight 30 or multi-viscosity?
Robot Cantina is running a 420cc predator in a Honda Insight, should check it out if you haven't already.
Rivnuts also come Indexed. So they will not turn. Easy to install just cut a small v cut with a small file in the hole and line up the index tab when installing. If the rivets loosens up it will still not rotate!
The pumps usually like to be ahead of the filter and push rather than pull through restrictions. As a fuel pump they die fast with restrictions. Could try putting the oil return in the head? May drop overall cylinder temp more?
Cool!!! I like the idea too!!!
These are great ideas!
Outstanding! I can't wait. :-)
😂ton of hose😂. Great video man!👍
drill and tap a thermal switch in the side cover to automatically turn the pump on and off?
Finally somebody else did it!!! That's awesome you guys, mine never had a oil filter for the cooler I really like what you guys did.
Are the oil drain points in the engine the same size as in a 212 ? What can I use to connect the oil line to engnie?
Click on Redbeard and UA-cam torches me with an ad about getting rid of my belly fat. Brutal
Also adding a filter and cooler pretty rad.
Since the pump is the last in line, wouldn’t it make sense to gravity feed into the filter and cooler?
Hello Red Beard's Garage,
Do they make a 40 series torque converter with a 3/4" bore driver pulley that you know of?
What if you used a pulse fuel pump on both sides of the system.
One pulse pump mounted on the head pan, this pumps from the cooler to the head and block, it also reduces the load on the underside pump that's behind the filter and the cooler, allowing it to pull more quickly with less wear on the pump.
So you can also set up an extra oil reservoir this way as well, like having a Harley oil can, so the oil catch can might work good for this, one pump can feed the can from the front oil plug, it pulls through the already saturated filter, then cooler, then pump, into the catch cans in feed, them at the bottom of the in feed you have another pump, cooler set up to push oil (that's already been cleaned so no need to further filter it) into the block and valve train from holes drilled into the tops then possibly have a pipe fitting that's internally threaded for a large size fuel jet (now an oil squirter) and OD threaded to fit the new oil cooled pulse system.
This takes load off the electrical system and allows for more gizmos and gadgets to be run off the positive case pulse, while the fuel pump is still run from the intakes negative pressure pulse on intake strokes.
3 pulse pumps, a tangle of oil feeds, coolers, and a catch can, and maybe a few sight glasses added to the lines at various stages to allow for an idea of the flow rate and condition of the oil.
For a REALLY high performance engine, this could become a great benefit, similar to normal liquid cooling, slightly less efficient than true liquid cooling, but it also doubles as an added oiling system by spraying lubricant directly onto the valve train, and the crank which adds to the engines already natural lubrication process.
And should you ever begin to burn oil, you have an ample supply before you actually blow the engine from oil loss.
Should the oil system fail in normal use, that's fine because it was a redundancy added to the existing oiling system to increase engine and oil longevity.
I like this engine
Are you going to test this set-up under a load? Just would like to know the temperature results then. The idea of returning oil to cool parts better sounds like a good idea.
Could you do a video using a pulse pump as an oil pump? It was a thought I had. Thanks.
What’s the biggest piston you can put in a stock GX340 Honda ten over .? 30 over ?
They are they also good to replace the stupid pulse pumps for a mod
If you got a ultra light flywheel do you have to have a cam or can you leave the stock cam in?
Couldn't you have just opened the fill caps(dipstick) and shot the beam right at the oil? Feel like the numbers would have been more dramatic from one another. Great video! Thanks for your hard work RBG!
Where did you buy the oil cooler? I checked harbor freight's parts availability for the Gx670 engine and they didn't list the oil cooler
Be neat if you run it for X amount of hours and then cut open the old oil filter to inspect it. Curious to see what all it will catch.
I do have a question , Why not return the oil thru the old governor hole instead of back to the drain hole ... it seems you would get even better lubrication to me and avoid the oil just shooting straight across and being recycled . Am I wrong ???
Buy a external oil tank with a clear see thru tube on the side to see oil level
Your pump should be level and the filter with the crankcase possibly lower than the crankcase so the engine is not overfilled and can start and run good
Isn't the pump supposed to be as close to the "source/oil sump" as possible? Would a 12v "diesel fuel" pump work good! Good Job!
I always wanted to add a an oil filter and oil pump to my predator will this work with a 212 or is it too small?
I wonder about the longevity of that pump. I want do something similar
Why not the pump check filter cooler sight glass back to the engine I would think that would be better ?
That's really interesting
I'm building a manco buggy, with a 420 electric start, stage 1 kit, governor removed, want to put a alternator on it for lights, winch,gauges.
super dan
Also when I do this do I still need a catch can?
doing the same thing for a 1983 XJ650... poor air cooled engine overheats and the valves get stuck from those everlasting red traffic lights in town. gets up to 280-330 degrees idling, 11x16 inch 8 pass cooler!
maybe ya could find a way to spray water at the small oil radiator, when you are moving fast it could help get rid of alot of heat!
I have a Murray explorer with a rear end which requires torque converter ,
I bought a 212 Predator and a torque converter. The torque converter I bought online the belt and length of the plate was too short how do I find the right one? Someone help please
Could you have this system running off a motorcycle battery or no ?
