ptr_drvr Posted July 3 Share Posted July 3 Hi folks, Hopefully a simple question - having not built my (or any) Caterham, do I need any special tools or know-how to replace the front wheel bearing? y NSF has failed and I have a replacement being posted to me, but I need to check if there's anything other than some basic tools required to get it fixed myself. As an example, is a press needed to remove or fit the bearing? Many thanks in advance! Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted July 3 Member Share Posted July 3 There's a vast amount of advice in the archives, including tools: https://duckduckgo.com/?q=site:caterhamlotus7.club+front+wheel+bearing And a Low Flying article, but that server seems to be down.

ptr_drvr Posted July 3 Author Share Posted July 3 Thanks JK. I had done a site search, but your link returned more appropriate threads. Seems like it should be a Go-er. Link to comment Share on other sites More sharing options...

Wrightpayne Posted July 4 Share Posted July 4 I have changed wheel bearings on other cars with a parallel punch and hammer. You have to be very precise and even tapping the outer race out and new one back in. A press would be better for getting the new ones in as easier to keep the race square.

SM25T Posted July 4 Share Posted July 4 Put the hub in a warm oven for half an hour. Put the bearing cups in a freezer overnight. Once you remove them, fit them quickly before they warm up. This makes quite a difference. Or find a friendly local garage with a press and bearing press tools ! 1 Link to comment Share on other sites More sharing options...
grumpy the 7th Posted July 5 Share Posted July 5 Tap the old bearing out (carefully) then use this to place over the new bearing (this keeps everything nice and square) and tap gently until the sound of you tapping changes. Then you know you have seated the new bearing as far as it can go. Link to comment Share on other sites More sharing options...
7 wonders of the world Posted July 6 Share Posted July 6 The alloy hubs need a gentle waft with a blow torch and the outer races will drop out and the the ones drop in. Avoid tapping them out as you risk galling the alloy. 1 Link to comment Share on other sites More sharing options...
StevehS3 Posted July 6 Share Posted July 6 I was wondering if it was really necessary to remove the outer race. These days is the race matched to the bearing? Link to comment Share on other sites More sharing options...
