All these videos will be gold for me when my MBX8T arrives and gets built. I appreciate your openness, genuineness and ability to want to just help people because of your raw passion. Thank you mate. Chris from down under 🇦🇺
Drake is always on top of his game. He is very knowledgeable and the best at what he does. I am finna send in an engine to get modified, and have new bearings put in it.
Warming up the crankcase with a hairdryer allows it to expand and easy installation of bearings rather than forcing a bearing into a tight hole eliminates any material being shaved off inside the bearing seat is better technique in my opinion!
Great video.. another thing to pay attention to is head shims. Watch you don’t loose them and that they are individually cleaned and put back on head button. If any grit gets between them it will through off your shimming.
Good stuff as always Adam. Putting the clutch nut on hadn't occurred to me, but I like that (when pushing the sleeve out). I'd always put a screw in the end of the crank.
When i do a tear down like this its around 5/7 gallons unless i have tuning problems just b/c i rather hopefully catch it b4 it destroys the os motor one cause they not cheap an two to use as a back up knowing its well taken care of an i learned over the yrs maintenance is key then its you must frist finish to hopefully finish frist but in my case just finish thats the tessmans thing sweet information on the ad edition os motor i have the las vages edition even tho i haven't been able to race much since 2016 but she is ready to go get dirty when time is right thankx for a direct how to video an your time
It really depends on the conditions your running in and how hard you've been running the engine. In most cases, there's not much to checkout. If you see fuel from around or near the front bearing, it needs a new front bearing. If it's making additional noise, it needs a rear bearing. I also offer a service to look over and check the bearings, compression, o-rings, ect. adamdrake117@gmail.com
Thanks for the great vid Adam. I too have the AD edition engine and it idles smooth as silk and packs a punch when needed. Also gotta love those 10 minute + run times. How often would you suggest to tear the engine down to take a look at things in-depth? Do you read your glow plugs as a tuning reference to see how things are going? If so could you make a video about that? If not please explain why it may not matter to you.
Thank you! Glad to hear you're happy with the B21AD engines. If everything is running well and there aren't any issues, there's really no need to tear down the engine. I only do it if I feel something needs to be serviced or replaced. I don't have a video on reading glow plugs as a tuning reference, but that's a great idea and I'll add it to my video list. Thanks!
Hey Adam! Super helpful video. No way I’d attempt this without guidance like this. Could you possibly link us to where we can buy a bearing removal tool similar to what you’re using? Thanks!
Hi, Adam! Great video! Thanks a lot! I know that its critical to keap your piston edges sharp, trying not to touch them while maintaining. Can a zip tie damage piston edges, especially when you're applying a lot of pressure to crankshaft for removing the sleeve?
Other great video. Suggestions you can make a video servicing two engines one new or brake in or low time use and other with long time use and show the differences. Or even better one engine used with correctly break in process and no abuses and other has failure or has lot abuses when is used. Thank's again for those tip and how to videos.
@@AdamDrake It's good too to show how you breaking method is better than traditional or other breaking methods. I know you are a busy guy. And race engines are expensive, you can make with cheap engines too. rsrs thanks for sharing your knowledge on videos. Help a lot! Here in Brazil we have good drivers and mechanic's but know others tips and techniques always is good.
Hello Adam, Thanks for another informative vid! Quick question - is the orientation of the clips which secure the pin inside the piston important? Usually the "end" of the clip faces up from factory - does it make any difference? Do you have any tips on how to remove/install them? :)
I also adjust the orientation to have the end of the clip facing up, but I'm not sure if it makes much of a difference. I usually remove the clip with a hobby knife. Yes, installing them can be a pain. Sounds like a good video idea. :)
What can be used to clean internals parts? Any special care for a crankshaft with putty? I have an engine that's have been stored for too many years and it is all gummy in some parts..
With Flash Point fuel you don't need to do this because it's a full synthetic based fuel and burns super clean. It's not a bad idea if your running a castor based fuel and have a lot of build up, but that build up is also helping to create a seal at top dead center.
Is this maintenance and cleaning engine video for all nitro engines? Or this one in particular. Sorry, I'm new and I'm trying to learn more about keeping up with maintenance.
If you have a neat bearing puller like that, it sure is simple..without a bearing puller its a pain in the a$$ and you risk damaging the case and/ or the new bearings putting them back in. Dont ask me how I know . . . Dont even attempt till you have a bearing puller. And they arent inexpensive at $100 just for the tool. Big reason why I run electric nowdays besides the other benefits of instant torque, insane motor lifespan, clean and vibration free. Nitro has seen its day, but it has definitely been eclipsed.
@@AdamDrake why do you feel this way? And how easily should a sleeve come out of the case? I have a P5 that seemed impossible to get the sleeve out of. Sometimes due to my experience I worry about the amount of force that I'm applying to certain parts, and get stuck. Then learn it's ok to apply more force than I thought to get something out, like a sleeve from a used motor. Wouldn't polishing parts make breakdowns easier, or is it just window dressing? Lol Thanks!
How many gallons of fuel/hours does a normal .21 engine in an RTR last? Keep in mind I am taking good care of it, using after run oil, not beating on it too hard and using 16% comp fuel.
I don't have much experience with RTR engines, but I usually get 10-12 gallons out of my engines racing before they become practice engines or before the piston/sleeve is resized to extend the life.
What after run oil do you recommend?? I have well over 20 niteos and run everyday but as you can imagine it takes a few days to run some of them. They may sit a week or longer before i run them and i know the dlc coated ones arent in as much threat of rust but the others are. I live in NM so not alot of humity but wanna want to remain rust free!! Thanks for the videos as always
Thanks for the tips, Drake. Would you have any idea to remove the sleeve if the zip tie isn't enought?? Lol... I am with an XZ-GT which the sleeve is not getting out even praying for it hahaha
Do you have the part number for the stock replacement bearings for that engine and you recommend using stock OS bearings or is it OK to use avid bearings
@@AdamDrake Thanks for the reply Adam. My question was more along the lines of, say I purchased an engine from your line. In general how long would the manufacturer continue to support said engine with things like replacement pistons, Conrod's, bearings, for users to purchase and replace in their engines to keep them going?
@@AdamDrake so can you tell me the difference between them cause I never did a resize before I would just swap out bearings an just add knee guys an re break it inn
Your video is good, but there is one point you're wrong. A reverse mounted piston will not run because the crank will hit the piston. The problem will not be caused by the backplate it's rather the crank that will crush the piston. There is no engine a reverse mounted piston can run, even not with a short stroke engine. And it would be good to tell that the screws are always tightened crosswise. The max torque for M2 is about 0,5Nm and M3 is about 1,5Nm with 10.9 screws, therefore I would never use a powertool...
@@AdamDrake I remember the Novarossi short stroke engines (SBK) didn't have the cut out at the backplate. but this engines are 20years old now. if no cutout at the backplate a reverse is possible, I agree.
Sounds good. Not sure about the Nova engines, but I saw a guy run two OS engines a few weeks ago with the piston in backwards. I had him turn them around and they ran great. It was pretty crazy. Haha
You sir are incorrect. There are engines that will run with a backwards mounted piston... I agree in most engines the piston skirt will strike the crank stopping it from turing over. ALL engines is not correct.. I have discovered this when helping a friend with a engine that just wasn't tunable... After about half a tank i told him bring it to the bench and we pulled it part only to find the piston was backwards... Never seen it before and flipped it around and needles to first start location and with in two laps had it ripping. After that time i have seen it a few more times.
Kind of wish Adam Drake does a biography video about his legendary career in RC. From his first model, race, and who has taught him everything.
That's a very cool idea, maybe I can work on something like that with Cory from 5150 in the future.

Thank you! The scary thing with putting a screw in the end of the crankshaft is it could break the head off the screw. That's a bad thing. Haha
@@AdamDrake Absolutely...Never really liked the screw idea, so the clutch nut will prevent that potential disaster ! Cheers!

The tool I use isn't available anymore, but I believe Reds makes a similar tool.
Man just watching this makes me want to get a nitro buggy instead of an electric one
:)
Where did you get the carb & exhaust silicone plug at?
I see the head button has a mark is it critical to have it aligned properly. All head buttons look symmetrical so I don't see why it would matter
Hi, Adam! Great video! Thanks a lot! I know that its critical to keap your piston edges sharp, trying not to touch them while maintaining. Can a zip tie damage piston edges, especially when you're applying a lot of pressure to crankshaft for removing the sleeve?
No, it shouldn't cause any problems unless it's some type of super rigid zip tie. :)

Awesome video.
Do you ever clean the top of the piston off? Or remove any of the buildup on the sides of the sleeve
With Flash Point fuel you don't need to do this because it's a full synthetic based fuel and burns super clean. It's not a bad idea if your running a castor based fuel and have a lot of build up, but that build up is also helping to create a seal at top dead center.
Yes no problem as long as you have the tool ....
Very true.
Hello Adam, I'd like to know if these bearing removal tools still available if so can you point me in the right direction?
Is this maintenance and cleaning engine video for all nitro engines? Or this one in particular. Sorry, I'm new and I'm trying to learn more about keeping up with maintenance.
This can be used for pretty much all nitro engines.
What do you think about the metod for removing the bearings when you heat up the crankcase and they Just drop out?
That works fine if you don't have the bearing tools.
Great tutorial. How often should this be done on an engine? Is there a general rule of thumb?
Only if you start to notice a change or problem.
If you have a neat bearing puller like that, it sure is simple..without a bearing puller its a pain in the a$$ and you risk damaging the case and/ or the new bearings putting them back in.

Thanks for the tips, Drake.
Would you have any idea to remove the sleeve if the zip tie isn't enought?? Lol... I am with an XZ-GT which the sleeve is not getting out even praying for it hahaha
I have a tool that I made myself and I believe RC Renew makes a tool for removing sleeves.
hi adam i usually algo give a ultrasonic clean to all the parts except the carb is it a good or bad idea?
Yes, I do the same most of the time.
Do I have to use a tork wrench?
No, it's nice if you have a torn wrench, but it's not required.
Thanks so much.

OS bearings are really good! For the money, the Protek bearings also work well.
@@AdamDrake how’s the protek bearings longevity wise. I’ve heard good things about them but I’m not too sure
What brand of nitro fuel do you use?
how do we tell if the engine bearings are bad? do they cause any running issues etc?
Video coming soon!
Whats the average span that a manufacturer will support an engine line with replacement parts?
Most race engines don't have a warranty, but if it's well maintained and tuned properly you should be able to get 10-12 gallons.
@@AdamDrake Thanks for the reply Adam.
My question was more along the lines of, say I purchased an engine from your line. In general how long would the manufacturer continue to support said engine with things like replacement pistons, Conrod's, bearings, for users to purchase and replace in their engines to keep them going?
Have you made a video about the front chassis brace and the difference between the short and the longer one?
I thought so, but couldn't find one. Basically the longer, stiffer brace will have slightly more steering.
Adam Drake awesome thanks! I've been using the shorter so I will switch.
@@Double0steve0 I usually run the short front brace as well. It's a nice tuning option.
If you put the piston in backwards you are going to hit the crankshaft with the skirt of the piston..... It would be catastrophic
Yes, it depends on the stoke of the engine, but the piston needs to be installed in the proper orientation.
I’m thinking of just doing piston sleeve an connecting rod as well bearings are is a pintch worth it on my ad 2
Yes, if everything is in good shape just low on compression it's worth resizing the p/s. Let me know if you have any questions. www.thedrakeracing.com
@@AdamDrake so can you tell me the difference between them cause I never did a resize before I would just swap out bearings an just add knee guys an re break it inn
What drill are u using ?
Makita TD022D. amzn.to/3D4deFz
Is it ok to clean the inside of the engine from time to time with brake/carb cleaner and than oil everything?
As long as you don’t have ceramic bearings. Brake cleaner and solvents can damage ceramics.
I don't normally clean the inside of the engine, just oil everything from time to time before storage.

a.d. would recommend you loktite the 4 screws on the cooling head
No way. It melts and can loosen the screws,not to mention make it easy to strip them later. Never had one loosen.
No thread lock on the cooling head screws.
@@AdamDrake ok thanks a.d. so just hand tighten is fine right no need for torque wrench to be involved
hai, where to get the bearing removal tools?
The tools I use are very old and were manufactured by GRP.
Thank You, now to go find motor tools for .12 .
:) I should have .12 resizing tools soon hopefully. We do have .12 engines available.
From the look of that cooling head it looks like the engine has never been used! Haha I guess you never flip over
Haha, it may have been used in truck. :)
what brand nitro fuel are u using adam?..
Flash Point 30% Race Blend
Hi Adam ,
This tool grp for bearing is in online ?
No, it's pretty old and not available anymore.
The hudy set is nearly identical in dark hudy spring steel. I cannot recommend it enough.
I have to get the bearing press tool!
It makes the job super easy.
How you clean the engine when It dirty outside ?
I usually use compressed air, paint brush, and cleaning putty. Looks like I need to do another video. :)
What is that bearing tool called ?
Engine bearing tool or engine bearing extractor.
Ofna bearing puller?? Old School
GRP. Yes, very old school. Haha
Are you really using an electric tool for it? 😓
