Bob, it's only a mistake if you don't catch it. Looking good bud!
Maybe I should just move down there! I’ve always thought that was a pretty great part of the world!
Thanks Jim , “The things I didn’t know at first, I learned by doing twice.”
It’s all good, I turn my music on and get lost in the process. There’s a whole lot of worse ways to pass the day.
Been waiting for this a long tim Bob!!! Your tenacity is really paying off!!!
Hahaha! Me too Willis! Me too! It’s been ten and a half months since I began. ( I lost a couple months due to the move and getting my new shop set up)
Funny, I saw those ears then looked at your bike in the background and knew what you did. . Thanks for the paint info. I know its in this thread somewhere but the darn thing is 90 pages. This has got to be close to a record post. I vote it the most interesting post on the 650 forum.
By the way that 77 is such a lovely bike.
Haha! I know huh? I just wanted to have a little blog to record my project! I need an index.
You have yourself a potential calendar girl there.
You are a funny guy.
Sorry GW, I took a double dose of my "smart-@ss" medication yesterday.
Besides - you guys have great weather while up-northers like me, Lakeview, Canuck, Gary and soooo many others have...well, lets not talk about the weather.
We have very little snow at the moment, which is a bit odd for this time of year around here, but the temp outside is a balmy 17°F, lol.
Well this morning I did a lot of chasing my tail , out looking for fork oil. First I went to Cycle Gear, but the heaviest they had was 20 weight, too light for my needs. So then I thought I’d follow 2M and get some cheap 20-50 car oil , so I went to Walmart. Nothing except premium motor oil available in that weight. So I settled on this, 30 weight , which is what my manual calls for.
I added just a smidge over what the manual calls for.
Then I buttoned these forks all up. Notice that the headlight ears have been repositioned.
After that, I knew that I wanted to get my battery box installed early on, because it is such a bear to wrestle in from the side. Coming in through the back, when there is nothing there was easy peasy!
I HAD THE RIGHT EARS IN THE WRONG PLACE.....
My front brake disc bearing conundrum......
Long ago I ordered replacement bearings for my front disc. From Partzilla, this is the number they show for my bike and it’s the same number on the bearings they sent me.
I dug them out today and even though the number on the box is correct, they are clearly not the same size as the ones currently in my disc.
Now here is my Yamaha parts manual.
Different number, close, but no cigar.
Lastly, I can see the number on my bearing
And if I google Koyo and that number I can find it for sale.
So what I’m trying to figure out , is if I order that bearing just by that number, would it be correct for my application.
I would just grease and reuse the bearings that are currently in my disc, but one of them feels crunchy when you rotate it.
Confused in Arizona
Bearings from the same mfr using the name designator number SHOULD be the same. There are about five key characteristics that define a given bearing:
Outer race OD;
Inner race ID;
Balls caged / not caged (the balls in that photo are caged);
Width axially (how much of the shaft will the bearing cover when the shaft is inside the bearing?);
Seal / no seal etc. (the photo shows no seal);
As long as all of that matches up - you should be fine.
The Koyo bearing on 123 bearings should be the same thing. Just to feel better can you check the measurements given at that site against the bearing in your disc?
Ball bearings are somewhat standard parts unless they are used in very special application like extreme high speed. Those often will have a code number besides the basic number that would indicated special clearances or higher than normal precision on the bearing. I have my doubts that any of those consideration apply to your application.
Now if you are planing on setting a land speed record on two wheels or if you were restoring a SR-71 Blackbird I might suggest something else!
Long ago, someone once told me "...When in doubt, the book prevails..." If that's what it says, I'd go with it. Whadya got to lose? Ya already bought the wrong part, right? Compared to what you've got into this (clearly) museum restoration (EAT YER HEART OUT, SMITHSONIAN!!!), bearings is cheap...
Deep groove ball bearing 16005-KOYO, Inner diam. 25 mm, Outer diam. 47 mm, Width 8 mm,
don't despair, compare!
ps talk about envy...
hadda ago get a bucket to catch the drool.
Kinda like how those ears looked the first way you had em.
Haha! Well thanks guys, I appreciate all the input, I’ve been scouting around and that size bearing is available at lots of outlets. I think I’ll go ahead and knock those bearings out and take some good measurements, I’m beginning to feel confident I can find replacements.
Bob, the parts pics aren't clear on this, and I'm not sure of the XS2.
But on the XS1s, the round can flasher relay mounts to the bottom of the battery box by way of a round clamp. The flasher body needs to be grounded thru the round clamp, to the battery box. Which requires that the battery box be grounded...
Have you looked at the bearing you got from Partzilla and checked for a number stamped on it's side? Maybe it's the same, or a variation, like with rubber seals instead of open? That new part number could represent an upgraded, maybe sealed bearing. They did that with wheel bearings over the years. Some early ones were open, some had metal shields. Eventually they changed to the 2 rubber seal types (2RS).
