Conversion of Halo Spin Doctor front hub to QR problem

Just wondering if anyone can help me with a query on the above.
I bought second hand halo sas wheels with spin doctor hubs and bought the axle conversion kit to change the front hub from a through axle to quick release. I've looked through the forum and have seen similar issues but couldn't find anything that solved my problem.
I firstly tried using the cones that came with the conversion kit but the bearing on the disc side of the hub is recessed so they weren't suitable. I then tried using the cone (the widest of the two) which came with the through axle kit on the disc side and although this fitted the disc side better it made the hub too wide to fit my forks. I also tried the shallower of the 2 cones that came with the through axle kit on the disc side and although I could get the hub into my forks there was still part of the axle tube showing meaning that the wheel wasn't secure.
The solution would seem to be making the bearing flush with the disc side of the hub and using the qr axle conversion kit. Is it possible to make the bearing flush with the disc side and if so how can this be done?
If this is not possible are there any other solutions to my problem such as different sized cones (I've looked for these but couldn't find any)?

you have the wrong kit. the spin Doc had a few different variations. the first had the disc side bearing recessed. then they had the bearing out under the disc and then there was the diatec hub that came on the very first wheel sets.

I can't quite figure out which of the above set ups I would need. Are these all still available?0
-
the top one which is the first version. IIRC they were not available but that was some time ago.
CALL www.billys.co.uk tomorrow and ask."Do not follow where the path may lead, Go instead where there is no path, and Leave a Trail."

Cheers for such quick replies. Will give them a ring tomorrow.0

I have an old kit knocking about somewhere - from memory, it looks like the top version. Whilst I definitely don't need it, I don't think I've binned it yet... I'll have a look when I get back home and if it's the one you need, it's yours...0

Thanks very much for the generosity. I'd be willing to give you a few quid for it if you do still have it.0 -
Ok, so just got home... Yep, got said conversion kit sitting in the "probably never to be used again but might be useful" box... If you pm me your details, I'll send it your way. It's definitely the top one in the picture - makes sense as its a fair few years old (but never really been used as I switched to 20mm straight away) it's as good as new so let me have your details and its yours.0

I don't seem to be able to pm you. Clicked on your username and there aren't any options under the 'contact Horton' bit. Any ideas?0 -
try now."Do not follow where the path may lead, Go instead where there is no path, and Leave a Trail."

Hey Ben, tried pm ing you a reply about the bearings, but it seems be in my outbox going nowhere, so here was my reply!
Hey Ben,
Happy Christmas and all that jazz... I'm 99.9% sure that the Spin Doctor Pro only relates to the rear hub - they changed the design of the freehub on the "pro" and if your rear wheel was bought at the same time as the front, then it will almost certainly be the standard spindoctor rear, not the Pro - the big difference is the std ones screw in and are bit of a pig to get off, whilst the Pro version is a push-fit - have a look at www,ison-distribution.com and do a search (top right) for Spin Doctor and you can see the difference if you click through the pages.
As far as bearings go, those ones on ebay look fine to me - about £8 is pretty reasonable - if you have a bearing shop nearby, they just need the size which is 6804 2RS (2RS = rubber seals and from memory, they are 32mm external diameter, 20mm internal and 7mm wide) and you can sometimes find they're cheaper than people on ebay - it's the same as most things - good bearings cost more and last longer, but they're easy enough to replace and I'm yet to be convinced that the extra cost is worth it but you'll get folks that swear that ceramic ones are a huge improvement. The "big" or "quality" brands to look out for are SKF, FAG and Enduro.
In terms of getting them out - take out the QR conversion kit thingymajig, look inside and you should see an alloy sleeve inbetween the two bearings. At each end, there will be a notch cut out - you stick a flat bladed screwdriver in from the other side of the hub, seat it in that notch and then tap tap slowly, but firmly and moving around the bearing to make sure you knock it out straight - it sometimes needs quite a firm smack but I would recommend a wood mallet rather than a proper hammer on the end of the screwdriver. Obviously repeat for the other side... Once they're out, give it a clean and i normally smear a little bit of grease to the outside of the outer race to stop it corroding in place in the future, then you tap it back in keeping it straight - again, slowly slowly.... You can try and find a bearing press, but I have always just used a 24mm socket as it is conveniently the same diameter as the outer race of the bearing!
It's largely the same for the rear as and when you do that, but a bit more involved - there's a "how to" on the "tech info" link ison-distribution website (right here intact: http://www.ison-distribution.com/uploads/techinfo_5.pdf
Cheers, and good luck (remember once all is done to keep the QR nice and tightly done up)
