MarkB Posted September 10, 2015 Share Posted September 10, 2015 Hi allI pulled my GT6 Rotoflex rear hubs today to upgrade to M12 wheel studs. I made up this puller from a Spit front hub years ago when the proper Churchill tool was not readily available. Probably not as good as the proper tool, but hasn't failed yet on a Spitfire GT6 and Vitesse.Mark Quote Link to comment Share on other sites More sharing options...
Paul Garvey Posted September 16, 2015 Share Posted September 16, 2015 Jigsaw do uprated shafts - don't know how much thicker, price or if they still use needle rollers direct onto the shaft.http://www.jigsawracingservices.co.uk/suspension.htmAnother option from the States - with nice chunky sleeved bearings - but pricey:http://www.chequeredflagracing.net/Custom_Parts.phpPaul Quote Link to comment Share on other sites More sharing options...
PeteH Posted July 20, 2017 Share Posted July 20, 2017 HICan I "Bump" this thread, I am into a full refurb of a `71 Herald 13/60. And have come across the same issue, the Hub is resisting ALL attempts at removal including a 10t press and heat!. The end result is that I can see distortion in the flange. I need the hub off to refurb the damaged parts (Backplate and grease retainer). Has anyone local to HULL. got access to the type of puller required. OR anyone got a Photo(s) of the Puller?. I have access to welding and machining kit and may be able to fabricate something that will work. IF I know what I am looking at?RegardsPete Quote Link to comment Share on other sites More sharing options...

Jonny-Jimbo Posted July 20, 2017 Share Posted July 20, 2017 If you're stuck, I have spare shafts knocking about... but I'm in Coventry, not Hull... Quote Link to comment Share on other sites More sharing options...
PeteH Posted July 21, 2017 Share Posted July 21, 2017 HiThanks for the info, I have most of the Bit`s I need kicking about in the garage I am sure. Hopefully some welding and a bit of Lathe work will produce a satisfactory Answer. Once removed a light skim should true the hub back up.Hopefully a replacement shaft will not be required. but I will NDT the Hub before I refurb anyway.CheersPete Quote Link to comment Share on other sites More sharing options...

PeteH Posted August 8, 2017 Share Posted August 8, 2017 Finally got the Hub off. the Mk3 puller worked!, (5" weldable pipe flange, 2-1/2" Galvanised Pipe 1" BSW Threaded stud with 2 nuts, and a lot of rather scruffy weld!), with the judicious use of the 7lb hammer!. (Mks 1 and 2 failed, But I have to admit my welding was not of the best!.) I had to Modify a bearing puller to remove the Trunnion, but the surfaces look as if they will take a new Needle roller. Hopefully the last damaged threads on the shaft can be recoveredEdit:- Clocked the hub up in the lathe and did a light skim of the face, Now Rebuilt and cleaned Painted. Checked the "run-out" on the Hub face @ less than 0.5mm. Threads are now OK, only light damage in way of the first 2/3 threads which are well past the Nut. Now moved on to cleaning up the spring.
