The SKF 639174 is apparently discontinued. I went to my local bearing supplier to order that part number. The roller cone, p/n 639172 is apparently still available, just not the set nor the bearing cup of the same 639174 p/n.
I did a bunch of research and found that there are pretty much an unlimited number of manufacturers who make the same bearing set. I found that bearings made by Timken matched the SKF number and when I clicked on application for that bearing, it matched that of a 1954 to 1962 Fiat 500 rear wheel bearing. You can search by that on any automotive supply site, Napa, Autozone and O'Reilly's included.
Anyway, I got a set of National Bearings from RockAuto for a whopping $32 delivered to my door. The National p/n is 07100 for the roller cone and 07204 for the outer cup. I measured the SKF bearings and they were more like 25.4mm rather than 26mm. That gave me the idea that they were actually fractional rather than metric. Once I researched by the size I came up with dozens more options than the now discontinued SKF bearings.
I work on mobile heavy equipment for a living. I've used National Bearings in varying applications for about 30 years now so I'm not worried about production quality. I would say the same of Timken or TRW. BTW, National is a Federal Mogul company out of Michigan. If that sorta thing bothers you, the bearings I received are made in Spain, not China....sean
Have to quote myself as for some reason, there is no edit option. What I wanted to share is, I finally got around to start assembling the front end on my 1993 Project bike. In doing so, I found that while the bearing set closely resembled the OEM set I removed, it was absolutely NOT the correct ID for the roller cone.
The 26mm diameter is correct. At least for the replacement steering stem/lower triple clamp I bought. The one that originally came with the project was completely thrashed. It could be the smaller diameter 25mm bearing set that I bought would fit that stem. I don't know, I didn't try. I ended up ordering a Corse Dynamics set from MotoWheels so I can continue with putting things together.
I just wanted to get it out there that the Fiat 500 wheel bearings were 25mm rather than 26mm so beware. Measure your particular steering stem before you buy...........sean
For some reason the image didn’t load anymore from my bookmark above, but I bought these and they work nicely. The spec says max load 75.2Kg. Should be enough for our oil coolers!
Below link is the overall Rubber Bobbin page so you can see what they look like.
You mentioned in your alternative parts list, "The fuel vent check valve for the 900ss (and others, possibly, which Ducati sells for $90 or so) can be sourced from a 2008 Kawasaki KLX450R and can be purchased new from Bikebandit.com for $11. It is plastic, not aluminum, but is the same shape and size, and is a nice dark grey."
Do you have the part number I can search? I've been to the microfiche at Bikebandit and the photo only shows a part number for the tube... but doesn't say for sure if it comes with the vent check valve.
Any one way fuel check valve works - be sure you put it on the right direction!
I put one on the end of the tube out of site under the body work. That kind won't work if you run it down the center of the steering stem nut, but an aluminum one for dirt bikes with the right size for the tube I used works fine.
Diameter of oil drain plug washers for 1996 900CR?
I've located some aluminum ones (similar to stock Ducati) in bulk (20 pcs) that go for $10.00 shipped ... $0.50 cents each! Various sizes are available, I just need to know which diameter to order. A 20-pack would last a lifetime with reuse.
Least costly ones on the likes of eBay are about $4.50 each (friggin ouch!).
Hi all. Happy New Years. Maybe somebody know alternative for cush drive rubbers(rear wheel dampers) for old monster/ss and others?
Partnumber: 70010591A / 70010591a

So, i have amassed a large amount of bevel/belt junk over my years of having ducs and have finally decided to build something out of my mess. my goal is buy as little as i can to build it, with the exception of proper safety/ running gear. i have a wrecked 860 frame, a couple 900/750ss frames in...
Just checking to see what others are doing with their bikes right now.
Since mine is new and I'm going down the customization path (busted up side fairings makes this easier than it would be if they were pristine), I'm doing maintenance, reading up on things I don't know about (plenty) and...
Been commuting on Suzuki GSX1000S for 4 years and put 60k miles on it. Before that had Honda CB and kawa. Never rode Ducati before.
Switched to 2019 Supersport S and had my first ride today. 40miles/50min trip.
First impression, compared to GSX:
1) Great control. Super light and nimble, true...
Might be a stupid noob question but I really don't know much about electronics so...
Which wires should I use to lengthen the wires coming from an Ignitech ignition?
I forgot to ask for a longer wire harnass when I ordered the Ignitech and now the wires are just a few centimeters to short to...
Found underneath the bike when reinstalling the carbs. Looks like it might be some kind of guide/retainer for the over/under throttle cables. But, can't find it in the parts diagrams, and can't figure out how it might be installed.
