Happy hunting!

[NorCoaster]

I've seen all that, but I think I might be able to get them faster through Applied Industrial Technologies. They bought and renamed Minnesota Bearing and have the drive side bearing...it's an NTN NA5904...and I'm sure they have everything else. Having alternative part numbers would be nice if anybody happens to have them

[3Phase]

Messed that all up, wrong seal numbers.

[3Phase]

Messed that all up.

Tried to turn left!



I used to have the interchange numbers and the dimensions but they disappeared in the last OS upgrade. I'll most likely find them after I look them up again. The major seal and bearing houses aren't letting me look up shaft seals by dimensions today, they only want to tell me how they're made.

Anyway, you get the idea. Don't forget the two hub o-rings.

[NorCoaster]

Awesome. Thank you! How exactly do I remove the clutch hub to get at those?

[3Phase]

It's hard to tell from the picture but the left-hand bearing and seal are both seated inside the wheel spindle, not the hub #10.

The o-rings are fitted to grooves cut on the outside of the spindle.

The hub is slipped over the spindle and the o-rings.


Set the rim on a couple of blocks of wood to keep it up off the ground so you don't slam/bang/bend/lean on or tweak the rear brake disk while you work.

Look at the picture (or print it), then take off the #21 bolts, remove the #20 dust cover and the #16 dust seal to get at and remove the #11 hub bolts.

The hub comes off the spindle, you change the o-rings, you put it back together.

It may not be that easy because the whole Magilla's probably been in place and pretty much undisturbed for over thirty years but that's it in a nutshell.

[NorCoaster]

I actually got it out with the same brass drift I used on the bearings. Few light taps on the ends of the bolts after breaking em free so they'd at least spin. Now it's all taken apart and mostly cleaned. Already put all the other stuff through the ultrasonic. Now I just gotta talk to Applied Industrial Technologies in the morning. They have the NTN NA5904...that elusive left rear bearing and it looks as though they have the 6304 from NTN too, but I need more experienced eyes to go through this list...

[3Phase]

Nice work.

Yeah, the NA5904 is a standard bearing number and the entire planet didn't stop using them just because Yamaha stopped ordering their special version.

From what I remember, the normal '5904 has a lubrication groove around the middle with a hole cut through the outer bearing race to lube the rollers. Yamaha saved a few fractions of a yen each by getting them without the groove and the hole because it wasn't necessary. The bearing's in a low speed application and packed with grease so there's no oil bath like a car or truck rearend and no grease galley drilled with a remote nipple to refresh the grease; simple but not conducive to long life.


Ultrasonic cleaners are totally bitchen', I got a cheap 10 liter heated cleaner to do carburetors and try to cut down on solvents. What kind of solution are you using to degrease the hub and other parts?

[NorCoaster]

I just use Simple Green and water in the ultrasonic. Gets the job done real fast. Most stuff everything I've put in from this bike has taken two 8min cycles. Round one is usually mostly Simple Green and I use hot water and kick the heating feature on. Second round is usually room temp water and mostly water.

[3Phase]

Rats. I had a gallon of Simple Green but it must have run off to 'Vegas with that Zep purple stuff 'cause both of them are gone. Oh well, time to go shopping again.

It was late and I missed it but what was it you wanted to know about the bearing(s) at your link?

[DiverRay]

Be CAREFUL with the simple green!! READ THE LABEL! it's NOT NICE to aluminum. I use Pinesol water mix, as it does NOT harm the aluminum. There was an aircraft lost because the owner used simple green.

[NorCoaster]

I've actually only used it after the carb stuff, but have a funny feeling I ****ed the carbs up because I used a low dose Purple Power solution on them in the ultrasonic

[NorCoaster]

Also, I just read that Simple Green IS safe for aluminum as long as you rinse the hell out of it immediately after

[3Phase]

Yep, Simple Green will etch and eventually dissolve aluminum so don't go dousing your structural aluminum or flight surfaces with the stuff. So will ammonia, Pine Sol, Zep, table salt, bleach, pool or battery acid and so on. The only thing that's 100% safe to use to clean aluminum is more aluminum.

I've been using tap water with a couple of spoons of sodium carbonate from my lifetime supply can of electrolysis electrolyte and some sodium metasilicate / TSP substitute along with a drop or two of Dawn dish soap. I haven't tried any acid solutions yet, just alkaline but it works so far.

I ordered some Yamaha carburetor dip from Parker Yamaha in Arizona (yes, it's legal in California) so I'm going to try it out in the ultrasonic cleaner when I do the carburetors. It should make a decent aluminum cleaner too but it's a little expensive for general use at ~$30/10 liters of solution.
