It is so interesting and im so thankfull that you post this video.. i assume this is the same for all Yamahas since ive got a 07 Yamaha r1 crankshaft to fix...thank you
what if you polish the rod journals so now they would be slightly undersized how can you select a bearing color, can anyone tell me which bearing shell color is the thickest and which is the thinest with that information you at least know which direction to go from the color chart as the more you remove from the journal the thicker the bearing would need to be, i would imagine the difference between the thickness of the bearings would be about .0005 in or a half thousandth of an inch or maybe a tad less
I have a problem sizeing the bearings on my yamaha r6, I can see the number in the cranckshaft (2222) but I can't see the number in the connecting rods? 2 of them are 4D but on the other 2 I can't see any number...
But, what if the codes are no longer oem, due to wear, damage or repair? Would you then have to measure, determine new values/color codes and order bearings based on those results?
Those numbers are really only good if you are working with a new case and crank. Those numbers aren’t going to be accurate on an engine with 30,000 miles. You’ll need a micrometer for new measurements. As crankshafts wear their OD gets smaller.
I have a 2011 Yamaha fz8. I’m replacing the crankshaft my crankcase number are 66665 the crankshaft web numbers are 11211 it follows the same rule for sizing x-y= bearing size but if the color code stops at 4=green what’s confusing me is with my crankcase and crankshaft Web I’m getting 6-1= 5 or am I missing a step ?
Hi Guys I desperately need your help to purchase the correct bearing for my 2007 Yamaha Waverunner FX cruiser HO. 1100. The crankcase number 6B600 Y-1 and the number on the flyweight lobe which is 22222-2322 MBC does not give me a code which is in the manual. Incase you can help the number on the Conrod end cap is 5B. I need to buy Rod and journal bearings.
i have problem with my r6, it have knocking sound, sometime its gone, when i rav more then 6rpm the sound will come again, and turn engine off for half hour the sound gone, what is the problem actualy
Is it possible for the numbers on the crankcase/shaft to give the incorrect bearing sizes? I'm experiencing seizing on my crank with the recommended sizes...
Damn! You did plastiguage and all that? Or did you use a micrometer and dial bore? I have my whole engine apart and just bought 10 new main bearings accorind to the numbers on my case/conn rod/crank, I guess I’ll just plastiguage them to check but don’t feel like doing it haha
Great video! I purchased a crankshaft and conrods for my virago xv535, but numbering is a bit different... Crankshaft has 22U-1, one conrod has 3Y4H and the other 3H3H.... How should I select the bearing???
That's the problem.... The manual describes only one number, but I have two numbers in each conrod.. Is it possible for one half to have one color, and the other one have another color?
Hello, this, as shown in the shop manual, is for new parts. But what if there is wear involved? I couldn't find any actual size specs apart from the color codes, and just choosing bearings one size bigger and hoping for the best doesn't sound too great to me.
Thanks for the reply. But how do I know which ones are "the right bearings" to select? Suppose I measure and the clearance is 0,02mm over the limit. Next step is to go online and order. Do I buy the same color as I have now? Do I go one size bigger? Had it been possible to get one sample of each size in front of me I'd just plastigauge each and keep the one that fits best, but that is not possible...
The only way to really do it is to get an original set and plastigauge, then reorder the size you need. It's not cost efficient, but it's the correct way to handle it.
Would be more efficient when Yamaha or somebody else would give the sizes for each bearing shell, then you can select what you want. I think bigger number means oversize bearing (journal is smaller).
Mr. Talley i have a cbr 100RR 2004 wich crankshaft bearings i need how can i see that. On you shop i dont see it. I see this on the crankshaft L2212 LBBBB
Numbers are your O.D. Code, letters are corresponding I.D. codes. So based on your code, 2 with B is Yellow and 1 with B is Pink. So your selection would be Yellow, Yellow, Pink, Yellow. #9 are the bearings and they are listed by color. www.partzilla.com/catalog/honda/motorcycle/2004/cbr1000rr-a/crankshaft-piston
Because the sheer force would tear apart standard ball bearings. They make these out of a softer metal, so when coated with oil, they wear but don't destroy the crank or block.
a have a problem, my cranckshaft is 12121 1111, my block is 5 and I use brown, black, brown, black an brown crankshaft bearings! but the second black and third brown, unexpectedly a strange noise appeared and when it opened it was scratched ugly the cranckshaft
@@frankiemarchese2978 my block was not 5 and the bearings were wrong, that's why it made the noise! then I saw that it was 4 I changed everything and it went back to normal, because the numbering is on the upper block of the engine!
what is the differences in thickness of the bearings from colour to colour ,, ie: Differences between Brown and Green ?
Mr. Talley Excellent job one of the best yzf r6 videos out on UA-cam
Thank you!
Partzilla hi I recently spun a bearing on my crankshaft. are any of the options of bearings undersized like maybe .20 or.30?
you cant imagine how thank full i am for this video

So what if it’s on different crankshaft you’re using
I have a 06 r1. Is this the same procedure for my bike as well
Same procedure, use the chart in the manual for the 06.
what happends if the number on connecting rod is not showing?
Thanks
This process are same to all bikes?

do u have a video for crankshaft shell bearing?
dont you have to do a crush gauge?
i have problem with my r6, it have knocking sound, sometime its gone, when i rav more then 6rpm the sound will come again, and turn engine off for half hour the sound gone, what is the problem actualy
check oil. Then start with a valve inspection.
Nice work I am from india
Thank you. What is the limit for the ovality of connecting rods ?? Anyone ? Thank you.
Time is a construct. It all depends on oil transfer and wear. Time factor is unknown.
Is it possible for the numbers on the crankcase/shaft to give the incorrect bearing sizes? I'm experiencing seizing on my crank with the recommended sizes...
You did the right math and that happened? Maybe you had a different crank in your engine?
@@frankiemarchese2978 I took measurements and everything checked out. Calibrated my torque wrenches. Ended up buying a new engine. 🤷

What year is your Virago?
It's 94. I've yamaha's workshop and Haynes manual
Something's not right. 22U-1 is the start of the part number. Are you positive there are no other numbers stamped anywhere on the crank?

You would use a plastigauge to measure them and select the right bearings.

Thank you i order the items now
hi can you please let me know if it would be ok if I go one size under my meserments as to keep more oil on the crankshaft?
It's not recommended, you will have a higher chance of spinning the bearing.
Partzilla thanks alot really appreciate this knowledge
ian a newbie here, can anyone explain why didnt they use ballbearing at some part of the engine?
Were you thinking of something specific or these bearings on the crank?
@@PartzillaParts yes, i was thinking about all of those bearing that looks like a piece of metal.
why dont they ballbearing all the things?
Because the sheer force would tear apart standard ball bearings. They make these out of a softer metal, so when coated with oil, they wear but don't destroy the crank or block.

You ever figure it out?
@@frankiemarchese2978 my block was not 5 and the bearings were wrong, that's why it made the noise! then I saw that it was 4 I changed everything and it went back to normal, because the numbering is on the upper block of the engine!
Oh so you made the mistake of looking at the wrong number? Im confused. My crankcase # is 5 and all of my numbers on the crank are 2
So if thats right then I need 2 which is black bearings because 5-2-1=2 (Black)
Im going to plastiguage when I install them
