This was attached to a mounting piece that had set screws and a key to hold it to the axle. It was not welded or braised. <br /><br />Through a series of errors I wound up having to cut the old mount piece off the axle with a Dremel. My favorite bike shop (Tipp Cyclery) had a new mount in their spare parts that he sold me for a trivial price. I also ordered a new freewheel with 2 extra teeth to lower the gearing a bit. <br /><br />The damage on mine included a deep groove in the axle, and the end of the frame where the bearing mounts was chewed by the drive flange, in addition to the damaged bearings. I ordered a new axle (around $40) and bought new bearings from a local farm/tractor supply place. I also got washers and 2 collars to fit the axle from the tractor supply. <br /><br />Before I reassembled, I cut off the damaged section of frame and squared it up, about 1/4 inch total. <br /><br />When I reassembled, I replaced the damaged bearings. I also added a washer between the drive flange and the axle both to take up the space squaring up the frame left, and in hopes that if the axle did shift again the washer would keep it from chewing into the frame. I added the collars on either side of the freewheel, and another washer between the non-drive wheel and the frame. Once I had the axle and freewheel aligned, I slid the collars so they were in contact with the inside bearings, in hopes that they would add a little more resistance to the axle shifting. <br /><br />If yours is braised in place, I can't think of any repair that would not require a new axle and freewheel mount.Sevesteenhttps://www.blogger.com/profile/15439626386416115766noreply@blogger.comtag:blogger.com,1999:blog-23800220.post-29581877395017351712009-09-20T00:26:55.077-04:002009-09-20T00:26:55.077-04:00Hello,

It seems to be braised on to the axle.<br />Is this freewheel supposed to be removable? The owner may have had this braising done previously unless it was manufactured that way. <br />Any tips on removal of the axle from the housing or in lieu of that, the suggested bushing for this without being able to remove the freewheel?<br />Appreciate any tips.Rob in New Mexiconoreply@blogger.com
