Buell and Sportster Pressed flywheels repair

3-12-2013 - We could already offer to repair a flywheel, as a new pressed crank is very expensive, but we felt we could do it better, and make it stronger then you can buy in the market.

We really felt we needed to make this better, as the fix we had  used was good, but was only a little improvement  over the new stock crank,

Now we can repair the old Buell bolted crancked flywheels (THAT ARE NOT FOR SALE ANYMORE) have a look here too: 

We talked to our business partner in mechanical engine work and discussed our ideas and wishes and they came up with a better solution

The biggest problem was the Tooling that was made, we needed a special press that way constructed constructed that we could press in the pins under controlled conditions and speed so the pins would not go in in with a lot of heat or friction so a lot of controlled force was needed ( heat between parts caused heat by pressing friction )  In the picture below you can see the press that was constructed. we can press now different size crank pins to.




Now we can be more precise in the alignment , we be giving it a little weld to ensure the flywheel assembly will stay better in line in the long run


Nice welding for longer lasting fun


we are using in our newly made big end pin a high quality tough steel so this makes this tough enough to take the punishment from a Buell rider, and give a good bearing surface hardness to last longer.

Our solution is tougher than the stock big end pin ( where the stock pin is only surface hardened and this layer can be deformed and will peel off ) and will cause engine damage.



Above you see our new Big end pin we sell also, used with our nw new developed bearing cage that are made from a very strong material much better then the cheap stock ones. In combination with our side play shims and connecting rod races specially made to size on every crank we get we will guaranty a perfect repaired Crank assembly , better than New and it will last a lot longer then the OEM.



this rebuild we can offer for all Buell models 2000-2007 with pressed 1” big end pin  and Sportster models with pressed cranks 2000- up with 1” big end pin
