bjohnson Posted July 21, 2011 Report Share Posted July 21, 2011 I'm planning on getting a spare set of wheels and wets over the winter for my trackday toy. Starting to think about captive spacers to make wheel changes quicker and easier. I've done some research on here and the www; there seems to be two trains of thought. Firstly the simple option; replace existing wheel bearings with a new bearing with a larger ID, machine a new spacer for each side of the wheels that will push and locate into the bearing with a resistance fit and stay there. Spacer needs to have an ID to match the wheel spindle so that all original parts can be used/retained. Spacers are retained in wheel so a couple of pairs needed to go into the wet and dry wheels. The alternative methid seems to be a far more complicated method of making, fitting and retaining spacers that are captive in the swingarm. However this seems to be somewhat over complicated and also requires re spacing of components such as discs, sprockets etc. First option seems pretty straightforward, but have I overlooked anything??!!

marcaztls Posted July 21, 2011 Report Share Posted July 21, 2011 Do you have oil seals either side of the wheel bearings? If so, make spacers with a small lip that squeezes past and sits behind the oil seals. Aprilia do this for example. Works a treat. Link to comment Share on other sites More sharing options...
Cibbersicks Posted July 21, 2011 Report Share Posted July 21, 2011 Mine sit inside my oil seals, it is a simpler way of doing things as they don't need to be pressed into larger ID bearings. They do make life a lot easier, especially with a bike like mine whereby the OE spacers are a "floppy fit" (technical term) and fall out the second you look at the wheel, and roll under the nearest toolbox whilst youve got your hands full. I don't know to any spacers which are captive in the swingarm, this would make things like chain adjustment impossible if they where fixed to the swingarm.

My Szr =) kind of a rolling project. http://i474.photobucket.com/albums/rr101/trx-girl/SZR660/May26059.jpg Link to comment Share on other sites More sharing options...
Cibbersicks Posted July 22, 2011 Report Share Posted July 22, 2011 Indeed but aren't these part of the quick release axle assembly rather that the swingarm itself? A fair bit of engineering would have to go into making this from scratch to fit a stock swingarm? I'd imagine the better route for the OP would be conventional captive spacers in the wheels... Lovely Superbike porn though... Link to comment Share on other sites More sharing options...
