Bearings for a Ultima Drag style open belt.

Activate · #1 (**permalink**) 08-10-2021, 08:56 AM

Hello,

I have a Ultima Dragstyle open belt on my bike.
The first bearings where shot after only 500 Miles so I replaced them with original Ultima ones ( 58-707 and the 58-737 and the 58-787 original part numbers.

I have thrown away the fist set bearings so I have no other numbers hen the orginal Ultima numbers.

I want to rplace them for a better brand lik SKF or something.

Does anyone have the bearing numbers or measurements for those bearings?

Thanks and greetings,

Erik.

Here is the PDF (Recommend Saving it) I have it saved and I dont have an Ultima Drive lol

http://www.ultimaproducts.com/BeltDrive.pdf

58-787 Bearing, Radial Ball, Single Row
58-707 Bearing, Ball, Double Row Angular Contact,
58-737 Bearing, Ball, Double Row Angular Contact

These are what came up searching for "Bearing" on the PDF, depending on what part in the picture, would be the stock one, One thing to check is if your clutch it too tough on the clutch, I have a Scorpion clutch on my FXR, I had to put the stock spring back on it, because it would chew up the clutch bearing every 3 miles and I would have to replace it on the side of the road.

Thanks for the reply.

That are the original part numbers as I mentioned above.

I have the pdf downloaded from the Ultima site.

I need the bearing numbers or size the bearing numbers are like 6002-2RS or 3002.

Thanks and greetings Erik.

I have taken the outer bearing support off and removed the outer bearings, they are 6006 rs bearings.

So now I need to know the numbers or the size from the 58-707 and the
58-737.

Thanks and greetings,

Erik.

The 58-737 and the 58-707 are 3200SER bearings but they can be 3201 3202 or??

honestly I think it would be worth measuring just to be on the safe side.

The 3201-3202- might be the style. But not sure. contact John at ScootersPerformance, Great guy, hes a vendor here (or was) who will definitely have the information you need.

Removed the clutch today.
Only the original Ultima number was on the bearing.

I have measured the bearing and it i a 3007 RS bearing!

Ordered one and hopefully I will receive it next week so I can change it.

Thanks for the help.
