To all that have F150 or up 200 the 90°Elbow next to the dip stick is regular iron and will rust causing the engine to intake metal particles thus trashing your cylinders. Also the nuts that hold the air water deflecter inside the couling also rust and particles are sucked in to engine just had to rebuild my engine with 350 hours. wish I could post pic's. You'll be aware costly venture due to cheap parts used by yamaha.
@@Schneids15so is it not common practice to change the tensioner as well like on cars? What's the service manual say about the tensioner? Wouldn't want that to fail
Thanks for this video. I blew out the upper crankshaft seal on a 2022 115 Yamaha. I managed to put those hair line cracks in the tensioner and have been stressed out about maybe having to replace it. Now that I understand how they work and your reassurance of it not being the end of the world I’ll continue with the project.
Thank you for your video. I have a 2006 Yamaha F250 and I just changed the timing belt and tensioner pulley today. I torqued the flywheel to 177 ft lbs by using your method of wedging a rag between the bendix and the flywheel and it worked like a charm. Great tip👍
gday mate one of the best videos i have seen you made it look real easy step by step , im lucky my little 40hp doesnt have a tensioner i think you must just stretch it to get it on , i dont know why people freak out if the timing marks move slightly just move em back and as you showed always turn your engine over by hand when finished to be sure .
Just ordered my belt and also a replacement tensioner today. I was also very intimidated by this job as well but not anymore!Thanks for for such a great video!
Thank you, well done sir. This is the best video on You Tube I have seen for the Yamaha 150 timing belt replacement. I have been looking at my new timing belt sitting on my work bench for 2 months totally intimidated about tackling that hydraulic tensioner. I now feel relieved, and confident, and will plan to do it soon. Please take pleasure in knowing your video has helped this old man tremendously.
I had a 150 where the flywheel was stuck on so tight I had to take the crank out with the flywheel and up it in a 20 ton press to get it out. When it popped out it was the loudest explosion ever.
Thank you, best video ever for replacing a timing belt on a Yamaha 150. Do you have one for the Balancer??? i want to do them at the same time. Also, what is the recommended hours to replace the tensioner? Again great job and very well explained. Yeah the wind noise is a pain, but your video is so awesome, it is worth dealing with it.
Great video! 🙂My 2008 F150XB service manual recommends replacing the timing belt at 1,000 hours. Was the 500 HR interval necessary due to the belt failing prematurely? Yamaha does recommend that the belt be inspected every 100 hours. Looks easier than I thought it would be.
That is interesting to know. I had always changed them at this interval when customer’s asked. Possibly different region’s/ countries have different specs for maintenance? The belt looked excellent still. No premature wear.
Extremely well done thank you. Especially the reminder of 500 hours. What is the time limit, usually there is 500 hours or five years? It is a rubber product after all.
Hey Jay. So probably wise after a certain amount of years. In my head i can’t remember a time spec on them just the 500 hours. If it was old with a short amount of hours i personally would visually inspect it.
The flywheel can be difficult to remove if it has never been off. A more stout puller like the Powerbuilt #648994 can work better than the usual 3 slot harmonic balancer puller. Use grade 10.2 M8 bolts because they will not stretch when you apply torque. The stator fasteners were combination Philllips-slotted screws on the ones I did, so using a stout slotted screwdriver with vise-grips to turn it will pop them lose. With the tensioner pinned in retracted position, I found it easier to remove it, put the new belt in place, and then reinstall the tensioner.
@@Schneids15 thanks. Mine have just grommets and no bolts that I could see, and lifting it lightly didn’t seem to be enough. After seeing you do yours, I think I’ll just apply more force. Thanks.
PLEASE watch other videos on the tensioner. If you try and release the tensioner with much force you will be buying a 460 dollar tensioner. They must be pulled back gently and very slowly. Other than that its a very good video.
Hey! Yes… the tensioner must be pulled with constant pressure as it is hydraulic. It takes time for it to go in and constant pressure is what it needs. I did specify this in the video.
After working on Nissan, and Mercedes Benz, and doing endless timing belts, and chains and guides,and tensioners, on 380 sl , and everything else, even an old Dodge Caravan,( what a pain) , this is a breeze. I even replace the snapped timing belt, , on my Deutz engine, in my bobcat, in the customers yard. ( talk about a project) I saw this setup on my motor after popping the cover off, I was like, no way, a timing belt can't be this easy.
Hi! Would Schneids15 happen to know (or maybe someone here at the comments) that what might cause a timing belt to run at the bottom of the pulleys? I just recently replaced timing belt and tensioner on my Yamaha F150DET (2019) and for some reason the belt is not tracking correctly. I tried moving it back to the center of the pulleys but it immediately comes down when the engine is started.
Never done a vmax. As far as i am concerned they are the same block and everything. Just different tuning and minor mods. Belt change should be the same. Depending on year.

@@wazup3333 No it is not. Just the belt it spec.
@@Schneids15 why not the tensioner too?
@@wazup3333 Probably due it being hydraulic and not a spring tensioner. I don't know for sure, but that would be my guess.

Hey Thank you! Yep on your 40 it will just slip over nice. They are very easy to do.
Just ordered my belt and also a replacement tensioner today. I was also very intimidated by this job as well but not anymore!Thanks for for such a great video!
Thanks Justin! Good luck with the job. It’s simple.
I was to about to buy a very expensive tool to hold the flywheel for my Yamaha out board you have just save me lots of money thank you for the info
Steve in Florida caught your video and enjoyed it thank you just had this done on my yamaha 115 at yamaha dealer but enjoyed watching the video

Wow!! I really appreciate that! Sorry again for the wind noise. I wish it wasn’t there but i an so glad i can help you. It is a very simple procedure.
Great job.
did my to motors in 3 hours, 1 hour for each flywheel to remove. 18 year old belts, 1100 hours.
Good to hear. Yes recommended at 500HRS but many so go longer. I have never heard of one breaking.
I had a 150 where the flywheel was stuck on so tight I had to take the crank out with the flywheel and up it in a 20 ton press to get it out. When it popped out it was the loudest explosion ever.

You made it so easy
couldn't you have left the stator on and just took the 4 bolts out?
Trying to think here on that one. It has been a while. There is a reason it has to be removed
Yeah I think you can eliminate that step… just do the 4 bolts on the mounting bracket and the whole thing will lift off .
Thanks for sharing. That pulley cover, does it just pop off, or Yadira you have to remove the grommets? Thanks
Hey! On some models they just lift right off. There is usually 2 10mm bolts with black heads in the middle of the cover. Pull them and it comes off.
@@Schneids15 thanks. Mine have just grommets and no bolts that I could see, and lifting it lightly didn’t seem to be enough. After seeing you do yours, I think I’ll just apply more force. Thanks.

$460 for the tensioner? Can the pulley be purchased separate from the tensioner?

I wish it was this easy on cars and bikes.
Great video. Thanks
Thanks Joseph!
@@Schneids15 I was going to have mine done this winter, or in the spring. After watching your video, I will be doing it myself. Thank you.
Do all of the pulleys have the timing marks on them?
Hi! Would Schneids15 happen to know (or maybe someone here at the comments) that what might cause a timing belt to run at the bottom of the pulleys? I just recently replaced timing belt and tensioner on my Yamaha F150DET (2019) and for some reason the belt is not tracking correctly. I tried moving it back to the center of the pulleys but it immediately comes down when the engine is started.
This is normal. There is a spec I can’t remember and it is only a mm or 2 or something from the bottom of the pulley where they run.
But it should not be over the bottom of the pulley? Because mine is maybe 1mm 🤔
No it should not be. Should be up 1MM or more. Is it an OEM belt?
No it's not OEM. Was thinking about that as well 🤔
great video.. thanks
Nice
are recmar timing belts any good? They are like half the price from any other replacement belts. Thanks
I have no experience with them.sorry
What did you end up buying and was it worth it ?
I have a 2013 f75 4 stroke Yamaha that tension pulley locked up while running and no video. Help
help
What about the vmax? I can not find any videos on max sho belt changes
Never done a vmax. As far as i am concerned they are the same block and everything. Just different tuning and minor mods. Belt change should be the same. Depending on year.
👍✌️
Don’t think you tightened down the stater bolts😕
