daffyduck1962 Posted July 19, 2017 Share Posted July 19, 2017 This is not on a VFR but I'm looking for ideas as I'm stuck, literally and metaphorically.There is no inner lip to strike form above.I've heated the head-stock but it will not move, I've adapted a tyre lever to try and get a purchase on the bearing but it will not move.

vegaquark Posted July 19, 2017 Share Posted July 19, 2017 Try with heat and a ice cube... Heat all the zone with a torch then apply the ice cube to the ring.. It should fall. Your last resort should be to take it to a shop with bearing extractors. Or buy one, but they are expensive for a one time job. Link to comment Share on other sites More sharing options...

Member Contributer FJ12Ryder Posted July 19, 2017 Member Contributer Share Posted July 19, 2017 Slide hammers and bearing pullers won't do any good if there's no lip to work with. Seems like you have two choices: Take it to a shop that has a good welder and have him weld some material to the race and then use a puller/slide hammer. It's possible simply the application of heat may loosen the race enough to be removed fairly easily. Get a die grinder and remove a small semi-circle of material from the headstock in two places opposite each other so you can get a driver on the race. Then drive it out. As a last resort, using the aforementioned die grinder to carefully grind a groove through the race. Link to comment Share on other sites More sharing options...
Auspanglish Posted July 19, 2017 Share Posted July 19, 2017 Assuming you don't care about the race being deformed at all you could use a dremel to cut some grooves which you then might be able to get some creative purchase on Link to comment Share on other sites More sharing options...
Member Contributer fink Posted July 19, 2017 Member Contributer Share Posted July 19, 2017 Try one of these. http://www.chainreactioncycles.com/x-tools-headset-cup-remover/rp-prod10223?gs=1&utm_source=google&utm_term=&utm_campaign=Chain+Reaction-UK-PLA-PLA-All-TB-SE-Shopping+QLB+Generic+Tablet&utm_medium=base&utm_content=mkwid|srsggjAib_dt|pcrid|161824956629|pkw||pmt||prd|31761UK m&p stock them but make sure you get the correct size Link to comment Share on other sites More sharing options...
Member Contributer FJ12Ryder Posted July 20, 2017 Member Contributer Share Posted July 20, 2017 The OP stated "There is no inner lip to strike from above.", and all of those tools require there to be an inner lip that can be attacked. No lip, those tools are less than useless. Link to comment Share on other sites More sharing options...

Yep. Three good MIG stitches around the inner circumference of the race that cover about 50% of the inner circumference will draw that race in enough upon cooling that it will fall out. In a previous life, many a printing press and envelope machine gave up races with no exposed shoulder with no drama after a couple of stitches.

Member Contributer mello dude Posted July 20, 2017 Member Contributer Share Posted July 20, 2017 Your working on a 5th gen? On the lower bearing there is a cutout that you can see from the top on opposite sides. Get a steel rod around 1/2 inch in diameter and 2 long line it up on the cutout and tap the race out -- The rod goes in thru the top. --- I just did mine. It was easy.

daffyduck1962 Posted July 20, 2017 Author Share Posted July 20, 2017 No it's not a VFR but was looking for ideas as the principle behind the problem could be just as applicable to any bike Link to comment Share on other sites More sharing options...

No lip, those tools are less than useless. From the picture there is no face to face contact so there will be a lip. Have had what I thought was same problem and I use the linked tool to remove bearing. The other option is the trusty old Dremel and caution.

Member Contributer maxredline Posted July 21, 2017 Member Contributer Share Posted July 21, 2017 As mentioned above welding a stainless steel bead around the center of the race (stick or tig weld). Make sure it is stainless as stainless shrinks more when cooling (coefficient of expansion/contraction) Link to comment Share on other sites More sharing options...
Member Contributer Mac Morgan Posted August 15, 2017 Member Contributer Share Posted August 15, 2017 Don't know what you're working but take a dremel tool and using a small carbide bit, grind a slot through the race- you are going to throw it away? Then you can take a pin driver and get it out. Link to comment Share on other sites More sharing options...
