- How to replace the journal type cam bearing in the XT225 with a 6005 type ball bearing. This bearing is a common point of failure in these engines. The cam bearing in one of my XT225s seized so I replaced the bearing in both bikes with SKF 6005 bearings. I made this video while working on the second bike. Same thing for TTR230.
The seized engine was caused by using an incorrect oil filter which blocked oil flow to the head. You may say that this mod isn't necessary if you use the right oil filter and I agree, however I did see some visible wear on the journal bearing I removed from the bike that wasn't seized. It is easy to do and only costs $8 for the bearing on ebay so that is why I'm doing it.

I was reading another forum article on this rework and he was saying much the same, with similar experiences. He did say that of the various types of 6005 bearing available he went for the 6005ZZ. The metal sealed ones would stand the cylinder head temps whereas the rubber seals may not. He also suggested removing the metal shield from one side for bearing lubrication but to keep the outer seal in place. his reasoning was that it would prevent head oil draining away when parked on the side stand.
Worked great, The only thing I did different Was clean the grease from the bearings and replace it with engine assembly lube so the oil passages didn't get clogged with grease.
This is a REALLY useful video with all the bolt sizes and bearing information included. Thank you for taking time to put all this together, you've helped out a lot of people.
Thanks for that. I have used TH-cam to learn how to do countless projects so I like to contribute where I can.
So the top end is pretty much identical to my Timberwolf 250 motor and i've been looking for a way to pull the camshaft out for maybe two weeks and I never considered using your method. Good idea frl really helped me out haha.
I did your mod to one of my bikes today. Took me about 2 hrs working slow. Plan to do the other tomorrow.
Incredible job and upgrade-well done man and thanks. You make what I wouldn't dream of doing look possible. A big thank you also for the wrong oil filters video.
I had a family member drop off their very neglected XT225 last week. Only 13k on the motor, but not much works on the bike. Winter project for next years fun. Thanks for this video, I will have to consider this since I have to reseal the motor, leaks like a sieve.
Great video man. Thanks. This weekend i will do the same.
Nice one, Alex. Just wasted an hour trying to pull out the darn cam without a puller. The way the cam was flopping around in there, I'm pretty sure the cam journals are toast.
I used the wrong oil filter on my wifes 230.... feel so stupid. Now researching engine stuff. Thanks for the video!
Hopefully you can fix it like I was able to, and it's an upgrade.
@@alexkram yea I like the bearing mod, how are the engines holding up?
Just did to two ttr230 worked great same bearing fit. Was surprised to see both aluminum bushings I removed had wear on them.
what cam bearing did you use to your ttr 230f and size may i see your upgrade?
That new ball race went in a little too easily for my liking. I think I would have used some Loctite Bearing fit just to make sure the bearing didn’t start creeping when in use. Nevertheless, great video, thanks for sharing.
Very good video. Thanks a lot!
Great job Alex
Great video, thanks
I just found this... excellent. thx
Well done!
Nice vid!
Отличная идея!! Привет из СССР
Bom dia, estamos colocando rolamentos nas duas pontas desse eixo, melhora o desempenho e acaba com o barulho
Buen día, tuviste que hacer un desgaste en el extremo interno para poner un rodamiento allí adentro también ? O que número de rodamiento usaste para que entre ?
Fiz na minha XT 225 por ocasião de uma troca de embreagem.
Pedi para colocar rolamento nós dois lados
Hey Alex, great video! My XT filter checked out fine, and engine still runs, but with lots of "piston slap" noise. I adjusted valves to spec, and they weren't far off. The bad; when I turn my crankshaft manually with a wrench, it makes a very audible metal friction sound throughout the strokes. Any thoughts before I take it into a local mechanic? Is a top end rebuild within a beginners ability and worth the $ for an XT? 10kmiles btw. Thanks again!
Te aviso que tal queda muchas gracias no se me había ocurrido 💪💪
Lo hiciste también?
El del vídeo dice que se lo hizo a 2 motos ya.
Que tal el funcionamiento con ese cambio.
Que tal amigos como les funciona el coginete
Thanks, thanks.
This was an amazingly helpful video!! Did you happen to keep your old aluminum bearing?
I'm here to help. No, it got trashed. You could see visible wear on it.
Very informative video. I just wonder if the aluminum bushing was designed in part to direct the oil flow where needed vs the bearing which may starve parts for oil?
There is an oil supply hole in the cam that supplies oil to the bushing. The bearing covers up that hole, which forces that oil to other areas like the other bearing and the cam lobes. That is the way I was thinking anyway. I have since sold this bike but it ran fine for 1000 miles before I did.
@@alexkram I appreciate the follow up!
Muy bueno lo voy a probar soy de Argentina. No influye con el flujo de aceite?
Buenas estimado, lo hiciste ? Soy de Argentina y pienso que debería hacerlo
I can not even press down both rocker arms without a pry bar. Any suggestions? camshaft seized, replaced it, both times can not push them down.
Did the bearing last? I got a moto 4 with the cam bushing worn out was thinking about using the bearing just like to know if it would last a while before I do replace it with a bearing.thanks.
Great video and thanks for posting. I made the same mistake this week with the wrong oil filter. The bike started chirping and then locked. It runs now (with the proper filter) but I've been told to do this. Are you fairly sure only the bearing is needed ? Thanks in advance.
I think so. It's not hard to do but you will have metal shavings to clean up too probably. I did not need to replace the cam when my other bike seized, I just cleaned it up with some scotchbrite.
@@alexkram Thanks ! I let it idle a bit with a new filter and there were no shavings at all in the filter. Odd.
looking on eBay/ i see the bearing mite be 25x47x12mm ?
🎥 👍 👍 👍
Is your knee completely better now? I recently broker my patella and will be starting physio soon. Praying I get a full recovery

Did it hold up well?
Just did this last week to a ‘97.
Gonna do it to my 97 this weekend
Stock Junkee84 put the bearing in the freezer for about an hour, it’ll help install
So far so good? How's it working for you?
Chad Dickerson no problems yet. Only had it on two rides though.
@@alexkram keep up inform🙏😁
Le queda grande el ruleman a árbol de leva influye en algo ?
hola, tengo una xt225 mod 2005, veo que decis que te quedo grande el ruleman y tengo en mente hacer este cambio, le instalaste el 6005 ?, o cual le colocaste ?, gracias.
@@guillermopenarandacuervo689 el mismo lleve a hacerle un buje así entre apretado
Whats the advantage of swapping to ball bearing?
There are a few advantages. I think the ball bearing will last much longer between failures because a journal type bearing requires some oil pressure to work and the design of this engine, with holes at the cam lobes, does not provide oil pressure to the chain side bearing. A ball bearing does not need oil pressure, just some oil now and then. This is my understanding of how these types of bearings work. Also the stock part costs $60 to replace while the ball bearing costs $5, so once seized the ball bearing is the cheaper choice too.
Any update on this?
Still going strong, 1000 miles later
I Think Yamaha TW 200 also need this upgrade ...
is it possible to do this for Yamaha TW200?
I am 99% sure it is the same.
@@alexkram Awesome. thanks.my tw's cam sprocket got a little play. Is it normal? How to know the collar is worn?
@@chamindaperera3257 it isn't that hard to take it out and inspect it but if you can wiggle it around that isn't good. Be sure to set those valve clearances after you make any changes.
@@alexkram Thank you. it's really helpful. ☺
@Suzukisan Thank you. I think my one is worn it wiggled more than 1mm horizontally. 😞
Was the bike making a loud ticking noise when this happened
I have converted two bikes. The first one I bought seized up so I didn't hear it run. The second one I converted is the one in the video and it's bushing was fine so the bike sounded normal.
That’s my question also. I ran my wr250 filter in my wife’s xt225. Just saw this video, and wondering if it will fix. It sounds like rod knocking
Wr250 fits an xt250- paper element. TW200, xt225, ttr225 and 230- same thing- all have a fine mesh metal filter with a special oil hole. Did you watch the beginning of the video? And in my opinion those ball bearings would not hold proper oil pressure
