b40rt Posted March 10, 2010 Report Share Posted March 10, 2010 Just noticed that the new wheel bearings I bought are C3, thought this was for engine internals only ! Does it matter ? Thanks Ross Quote Link to comment Share on other sites More sharing options...
wayne_weedon Posted March 11, 2010 Report Share Posted March 11, 2010 Just noticed that the new wheel bearings I bought are C3, thought this was for engine internals only !Does it matter ? Thanks Ross Ross Maybe not. Probably just end up a with a little more clearance than standard bearings. C3 have more radial clearance to compensate for the more severe interference fits as used internally in the engine. Wayne..... Quote Link to comment Share on other sites More sharing options...
b40rt Posted March 11, 2010 Author Report Share Posted March 11, 2010 "C3 have more radial clearance to compensate for the more severe interference fits as used internally in the engine." Hi Wayne The bearings seemed at the time to be "looser in the hub" to the extent of using "bearing fit" to secure them. As they were new hubs and I put it down to a "tolerance issue" Will probably change them sooner than later as I don't want them spinning in the hub !

wayne_weedon Posted March 11, 2010 Report Share Posted March 11, 2010 Ross C3's should be no looser than standard as far as the fit in the hub is concerned. It's their internal clearances that are looser to allow for use in housings that are tighter fit by design to allow greater working temp range without spinning. A normal grade bearing in a C3 specified housing would run tight. Wayne.... Quote Link to comment Share on other sites More sharing options...
