viperbl Posted August 26, 2013 Share Posted August 26, 2013 Guys, got the hub upgrade kit off caterham. When fitting the disks it was very tight with putting the bolts in, did not think too much about it until I went to put the wheels on... my MB wheels will not go on at all ... good few mm difference it PCD it would seem. Tried my old hub in the wheels to make sure I am not going made, prefect fit. Does anyone know if these upgrade kits are built a little differently?? cheers Link to comment Share on other sites More sharing options...
viperbl Posted August 26, 2013 Author Share Posted August 26, 2013 Here is a picture to help, used a bolt to align one side. http://postimg.org/image/t9sez2bsp/ Link to comment Share on other sites More sharing options...
Nigel Fox Posted August 26, 2013 Share Posted August 26, 2013 Are the wheel studs in the new hubs in square? ie. perpendicular to the wheel mounting face. Link to comment Share on other sites More sharing options...
viperbl Posted August 26, 2013 Author Share Posted August 26, 2013 Quoting Nigel Fox: Are the wheel studs in the new hubs in square? ie. perpendicular to the wheel mounting face. as far as I can see they are... but, The old hub has a distance of 96.1 between studs. The new hub has 94.9 and 94.7 between the insides of studs... Link to comment Share on other sites More sharing options...
Jonathan Kay Posted August 26, 2013 Share Posted August 26, 2013 The bolts in the new hub don't look true in those photos. Can you take them out, align the holes in the new old and new hubs and post the photos? And/or measure the distance between the holes.

Jonathan Had a look at the picture and you are right, looks on the p1ss for sure, checked the bottom of the bolts and they are 96.1 so it is the top of the bolt that's on the piss ... manufacturing issue then! wonder if the holes are straight true ... both of the hubs are the same.

viperbl Posted August 26, 2013 Author Share Posted August 26, 2013 Jobs a good un! thanks guys and Ruffseven for the idea of putting loads of washer on the stud and tightening up the bolt to straighten out, did the trick :) Link to comment Share on other sites More sharing options...
Jonathan Kay Posted August 26, 2013 Share Posted August 26, 2013 Can't picture how that straightening trick works... more details, please. Thanks Jonathan Link to comment Share on other sites More sharing options...

Thanks Jonathan If you pack out beneath the wheel nut with washers, tightening the nut will pull the stud tight against it's 'head'. As the nut is pulling against the face of the hub the stud will always align itself as you go. Link to comment Share on other sites More sharing options...
Jonathan Kay Posted August 26, 2013 Share Posted August 26, 2013 Is the "straightening" about reseating the stud so it's true to the face of the hub or about bending it straight? Thanks Jonathan Link to comment Share on other sites More sharing options...
Englishmaninwales Posted August 26, 2013 Share Posted August 26, 2013 Reseats the stud. I had the same fitting new (longer) studs. Link to comment Share on other sites More sharing options...
viperbl Posted August 26, 2013 Author Share Posted August 26, 2013 As Garybee said, and I hope its just re-seating the studs and not they were bend. All good now and wheels are on Link to comment Share on other sites More sharing options...

Gregs79 Posted August 27, 2013 Share Posted August 27, 2013 What does the hub upgrade give you over the standard set up? Link to comment Share on other sites More sharing options...
CharlesElliott Posted August 27, 2013 Share Posted August 27, 2013 It has a bigger stub axle, which is less prone to breaking (I've seen the old ones snap on a race car) It has bearings with integrated rubber seals rather than the felt ones. It has aluminium hubs, although these can cause problems with the bearings which can wear the aluminium over time. Link to comment Share on other sites More sharing options...
