Yamaha TMAX Major Service : Part 2 : Valve Check & Adjustment, Camshaft Installation & Removal
ฝัง
- เผยแพร่เมื่อ 28 ก.ค. 2024
- In this video series, I'll be replacing the fuel pump assembly and doing routine maintenance to my 2011 Yamaha TMAX 500. The service manual recommends a major service every 12,000 miles and a valve clearance check at 26,600 miles. My TMAX is at almost 28,000 miles, and the last major service was at 12,000 miles, so it's time to dig in.
In part 2, I'll be removing more body panels and components to gain access to the engine to do a valve check and adjustment. The valve check and adjustment process is shown in detail, as well as installing and removing the camshafts and timing chain tensioner. How it worked for me, how it didn't, and major fails.
If you own a TMAX and are considering doing your own service, or are thinking about getting a TMAX, I hope the TMAX service series will help you get an idea of what it's like to do the 12,000 mile service, due at 12,000, 24,000, 36,000 and so on.

T max owners are extremely lucky to have you posting this video on TH-cam. This is golden.
It would have helped me much more if he let ME fast forward the video instead of HIM. He has plenty of time to hide negative comments.......why not make your channel BETTER by NOT increasing playback speed? Let your viewers have that option.
@@Stewsdrums Because I can actually see the viewer retention stats for my vids (average time that people actually watch a video). I'm trying my best to be helpful and make videos that people will watch, but I will never be able to please everyone so I go with what seems to work for the most people. On the flip side, some people complain that my videos are too long when they're half as long as this one.
@@Stewsdrums Dude... If these videos are not adequate enough for you then you're helpless. Don't bother tinkering on your bike, because you might drown in deep waters. I wish he would cover my bike. Absolute goldmine.
@@49ccscoot I understand. And I subscribe. I miss so much really great stuff that you speed up. It's just a shame to me because it's great stuff
@@moslimislam5714 I am wanting to watch his videos at normal film speed. That is all.
Amazing video. I haven't managed to get through it all YET but I can already appreciate how informative this video is as well as the amount of effort and time it took you to film and edit the whole process too. This will be my manual when i get round to doing it
Such great videos. Informative, honest, and thorough! I don't even own a tmax but I learned so many tips through this video.
What a ride this video was. Thank you for including the miss as well, it does wonders for those of us not quite on par with your skills.
You are my hero.
I salute you.
Good luck with the valve.
Awesome video , very detailed showing all steps of installation and removal. Great Job!!
Glad to see you dont hide your mistakes
Followed your channel for years.
Not giving up on you now !!!!
Integrity is rare
Ive linked this video to our tmax owners club fb.
I feel your pain Brent. Hopefully you'll fix that changing the damaged valve and installing a new head gasket and be done with it. We all learn from our mistakes. It's good you are skilled enough to have seen the problem before engine assembly.
Great video. I’ve owned Two Tmax 2001 and a 2004 model.
Fantastic bike, but expensive to repair if you are not mechanical minded, when they start to age with high mileage.
I tried this particular job on the first one, the bike did run afterwards, but never got the tapping noice out of it.
When I changed the chain tensioner on the second bike I used cable ties on the chain and had no problem with the timing.
Learned a lot here, might start that job myself soon now that it has 50,000 miles on it!
Gran experiencia! Muchas gracias por tu video. La honestidad es un valor casi extinto.
Thank you for telling us your experience and for your honesty.
I think this will help me a lot when I ll do it on my tmax. 👍
I tried it in my most recent video with the aid of cable ties and combining those with the order that worked best for me from this video made it a much easier process for me.
Excellent thanks 49cc scoot, I hv read Tmax service manual yet but this video most clearly that
...you honest and that my friend is priceless! ty
MOLTO PRECISO E PULITO NELL'ESPOSIZIONE. BRAVO.
If i knew half as much as you am sure i would get into twice as much trouble...nice work m8 👍😄✌
Hi Brent,great video and thank you very much to show us all details.I have the same Tmax and I already done valve clearences twice.I always follow Yamaha service manual and I always put chain tensioner at the end,not like you.Its not easy because of force from lobes,but its possible.But I still dont understand a reason why this valve have problem,cant see any mistake from your side.
One other thing, after decades, I finally bought a METRIC feeler gauge set (the type that features whole millimeters instead of imperial). No need for mental conversion as the shims are sized in metric. It was the best thing I ever did in my life. Well, not really the best thing but close.
You don't get much for $87 at the Yamaha dealer!
I put the valve down to bring tired, and frustration. Like you said it's nearly impossible without some sort of locking tool, or cable ties.
Still a very educational video. Which I'm sure will help others not make the same mistake.
grate video i dont even own a tmax or intednd to buy one but i always lern something
6-8 thou is small, we had these settings on some of the Jaguar sixes in the 80s. Not easy to set, especially as one has to physically feel the valve lift ever so slightly off its seat when the correct clearance is reached, otherwise the engine will be noisy. Pushing in a 6-8 thou feeler gauge under these conditions is challenging.
I feel the struggle my friend,I had to clock aftermarket cams(tmax 530 gears on 500 cams) reprofiled without markings on,that was a pain....once you figure it out though(here comes experience especially when you are into tuning) its just another job...
Muy bueno, muchas gracias.
티맥스 정비에 관한 영상 감사합니다!😊
Sorry Brent, I feel like I should have shared my 'trick' on Tmax forums five years ago when I did this. My method seemed risky and I had 'imposter syndrome' about it, but it worked for me. I tried the 'awl' like you did but was never satisfied with it after seeing the chain skip for myself. My approach was to torque down the exhaust cam 'cap' and cheat by using a screwdriver in the teeth of the exhaust sprocket to back-it-up so much as to actually lift cylinder 1's exhaust valve a bit to grab the chain and let the valve spring 'catch' the timing chain taut on the underside. oof. I know. If I had a trick to getting the intake cam in place from there... I dont remember at the moment... but it probably had me dipping into valve spring tension there too. I definitely remember installing chain tensioner last of all things.
47:00 I don't see this as an optional step. [measured] values of shims is what the math should be based on - screw whatever the shim print says or what the shipped invoice says. I am more likely to believe a large shim was printed with a smaller number or vice versa than you bending a valve stem. Unless you swapped camshafts and completely botched the ICE timing while hand-cranking.
Odcinki super 😎
Have you seen what goes into making quality O-rings? I'm supprised they do not cost more! With the work, and R&Dand testing, it's crazy especially when they are made from more exotic materials!! And they are made slower than I would have thought!
It's not something that I'm going to try to save on. I think if you are certain of what the o-ring is, and there are multiple options, and can figure out it's dimensions accurately... then you can save. However, who needs a pack of 50 fuel injector o-rings for a TMAX, and if you only use 2 you'll spend way more.
It would not be worth the savings if any properties were wrong and it all goes back together and leaks. Just take my $4.XX per o-ring Yamaha.
It's a good video to me, I also DIY maintain Tmax in Taiwan. Thanks
Hello man, I am from Iraq, I have a Yamaha Tmax, and I have discovered that it is damaged. Return. Help me how to fix it. There are no spare parts in my country. Can you help me how to fix it?
Hello Sir , very good videos and explanation, i have an issue with my tmax 2014. that it doesn't pass 5000rpm, it hangs or cut off and on when reach 5000rpm, like its goes into limp mode.
I have check scan the issue and it is telling me code 12 , crank sensor but i can't seem to find any crank sensor on this Engine. I have check all speedsensor and no issue and also no abs light on.
I dont have a Dealer where i come from so, i was wondering if you have knowledge about this issue. The strange thing is the ECU doesn't allow me to reset the codes. the person told me the ecu is locked.
please any help will be helpfull
Your compression tester immediately going down like that is not due to a bad seal between the tester and the engine. There's a leak somewhere in the compression tester hose or gauge. The compression tester should maintain pressure even if you take the gauge out of the cylinder. If it wasn't designed like this the compression tester would act as part of the volume of the cylinder and you would get lower readings then reality. Most likely there's a Schrader valve at the bottom of the hose that's leaking.
Thanks. I realized this after watching it back for editing. I've been spending roughly 70 hours a week on scooter work and video editing lately and it seems to affect focus a bit.
@@49ccscoot i can imagine.
You did a great job regardless of the outcome!
Did you by any chance try to check out what the service manuals of model after your tmax say on the matter? I cannot imagine the design being immensly different and hence maybe yamaha realised and made a better detailing of the steps?
I couldn't find one at the time. Someone actually sent me one from the next gen to add to my collection very recently, but it looks the same.
Hey man where do I adjust the vales on the lazer 5 man. I just got one and they need some tuning
The owner's manual says 0.03mm intake, 0.05mm exhaust.
If you need any info on the valves/cam, this may help. It's my 160, but similar processes.

Can i ask you guys, i got engine check light on, number 46 what does that mean?
Someone posted the whole list of codes here :

Hi Brent why on my rotors flywheel there is no timing mark?
Not sure why, but I've heard of flywheels not having any marks. Seems to be even more common with replacements. I would suggest looking at a service manual to see if they show a mark on the flywheel being used. You can make your own mark, but you have to be careful to be accurate. A degree wheel and piston stop is my preferred method. I've got some vids about TDC.

Hey excellent video.had a 2004 tmax in my country in senegal Now i am an automotive tech in atlanta ga and do lots of timing chain jobs. Zip ties are very handy to hold chains in place. . At least we will have a cylinder head video on a tmax . Can the head come off with the engine mounted in frame?
Yes, the head can come off without removing the engine. Cylinder could be done too. If only I could afford the 560cc big bore kit.
Yes that would be the perfect time to put a 560 kit. But yea the malossi kit with performance cams around 1600 on ebay
@@ousmanesarr7287 It's a lot of money for a little HP.... and you can't get blood from a turnip. lol
Hello. How many kilometers have you made the tack adjustment?
~45,000
Its the same feeling when a tool slips off from something and scratch a surface what you cant repair. Even when your hand is 1000% stady and you concetrate so much.
Is this scooter the same as nmax in the Philippines let me know thanks
Google says the NMAX is 125-155cc. This is 500cc. I'd expect the NMAX is more similar to the SMAX here, which is 155cc. We no longer get the TMAX, but now they sell a 300cc XMAX.
In your opinion is the 09 Tmax worth it? I found one for $4500 with 7k miles, and also found a 2018 xmax with 4k miles for $4000. Which one would be the best purchase?
The TMAX is more powerful and probably better suited for long distance riding. The XMAX should be way easier to service. I think you can do a valve adjustment with just removing the seat instead of this huge process for example. The '09 TMAX is now 12 years old, so it may need some checks and maintenance just from age.
@@49ccscoot thanks for the information, im somewhat able to do some maintenance on the tmax but the bigger things like valve checks i would bring it in to the dealership. I will be doing mostly city driving with some occasional highways
@@Night_Watch413 I think I'd go with the XMAX based on that info. The XMAX should be capable for occasional highway riding or even regular riding. If you want to get out on a highway and cruise 80MPH all day, then you need the TMAX IMO or some would prefer even more powerful bikes. If you want to ride around at 55-70MPH, I'd imagine the XMAX is more than capable.
The TMAX is really surprising in town, so I don't think you'd have any trouble there. It weighs nearly 500lb, but it's very easy to handle. Still, you really don't need such a monster for mostly city riding.
The difference in maintenance hassle may be enough to save you a lot of money by doing your own repairs on the XMAX where you may not do some tasks on the TMAX. Even if you did take it in for work, the bills for the XMAX should be considerably lower than the TMAX for some jobs because it would cost a small fortune just to have a mechanic remove the stuff to get to valves on the TMAX for example. Even CVT work has to be accompanied by removing body panels on this thing.
Good luck with whatever you choose and ride safe. Lemme know what you get!
I need a yamaha majesty series,unless its almost the same.
I've never worked on one. I'd imagine it's similar in a lot of ways, but not the same.
What's going on with the TPR build? Any new videos coming?
Just started working on it today. Have been waiting for a piston for 3 months.
@@49ccscoot god... that's a lot of time waiting.. Looking forward to the new video tho! On a side note, I'd say that now might be the time to take a look into an EGT sensor-gauges in order to have a clearer representation of what's going on in the engine next time..
@@boostedhub7762 Prob not a bad idea.
Just got an email this morning that parts for the TMAX won't be available till July and they aren't in stock anywhere.
@@49ccscoot Hello man, I am from Iraq, I have a Yamaha Tmax, and I have discovered that it is damaged. Return. Help me how to fix it. There are no spare parts in my country. Can you help me how to fix it?
i snapped my crank twice just because i thought my flywheel is tight enough
So many parts make up the Tmax. I’m not sure how you keep it all straight.
All corners of the garage are filled with body panels and sandwich bags.
Always wanted to get a Tmax, they are soo good!! But boy oh boy they have bolts and pieces.... what a headache lol
When you have to work on one, you appreciate even more that you don't have to do it often.
34:38 can we talk about how the Tmax's starter is right here and what it takes to get to it? It is the third check point in the service manual for a no-start condition. Turns out I had a blown diode and never needed to take off the gas tank. Thanks, service manual.
@@staunch_risk_indicated4348 Some access panels could go a long way. I think I'm not alone that when I realized that you have to remove the windshield, mirrors and body panel to get to the battery; I knew this thing was going to be "fun".

@@49ccscoot Can you help me how to fix the crankshaft and bearings please help me
@@user-ve8if8se5e That's a big job. I'd suggest finding the parts first. It's going to be a lot of parts, with gasket and seals and so on. Get a service manual and/or look on a Yamaha parts site. Then see if it still seems worth doing. For example, in the US I am seeing the crankshaft as $840 from Yamaha

Glad I have a Morphous! To get to the head, you take the cargo bucket out. 60 sec max
That is Not saying that I didn't like the video. Loved it
Au travail
Dummy! 🤣 Just kidding. It happens to all of us. DOHC do take some getting used to, and every manufacturer does them a little different sometimes. In most cases, I almost always tie or wire the chain to the sprocket even if the instructions don't mention it because sometimes it can jump when you aren't looking at it then it will never line up right. Some Kawasaki engine manuals even tell you how many chain links there should be between each timing mark on the sprocket so if you lock it down and line it up on the crank it's golden.
A bit more complex than a gy6! I'm glad my doctor isn't as thourough as you! Haha..
🤣 Come in for your yearly multi-point inspection.
You can see how a decent electric E-MAX will destroy many many garage jobs!
In many cases I don't like electric. I enjoy engines. I could deal with never having to get so deep into a scoot like this though. You know they'll make some routine thing require 4 hours of panel removal just for fun though.
@@49ccscoot do you ever feel a right old engineer would come up with far more common sense approaches - like a battery accessible for starters?
@@drdoolittle5724 I think every mechanic or tinkerer has cursed an engineering team or three before. To their credit, it has to be a tough job to fit what feels like a million things onto a motorcycle.
@@49ccscoot just after finding your work I tripped up on a Honda Silverwing vid and low and behold, battery just under seat, 1 or 2 bolts, job done! Next, how to remove plugs, few nuts and bolts, job done! See, it is possible!!
@@drdoolittle5724 My opinion of the TMAX is that they focused on handling and styling and the rest was whatever could work for those.

Cood
1 year earlier i did an overhaul engine rebuild in a yamaha tdm 900. Every time i did things like service manual says, always i made tings wrong. Yamaha service manual is only to set a fire. ALWAYS the worst manual in every bike , mopet, boat engine etc.
bottom line you fucked it. all you had to do is the way Yamaha specify.
