Gromit Posted April 16, 2008 Share Posted April 16, 2008 Well, I've been a bit of a muppet. The inner hub seal was throwing oil all over the brake disk, so I pulled the hub last weekend. In my enthusiasm drilling a hole in the oil seal, I damaged the hub. The hub now has a grove in it, where the oil seal sits, where I caught it with a 3mm drill bit Thinking it'd be fine, I put a new seal in and put it all back together. 3 days later and it's leaking again. So, can i fill the grove with something, epoxy or chemical metal, and sand it down flush and refit a new seal? What would ye recommend?

Jon White Posted April 16, 2008 Share Posted April 16, 2008 Probably be ok to just bung it up with a bit of RTV sealant for the time being and look out for a new 2nd hand hub. Jon Quote Link to comment Share on other sites More sharing options...
Les Henson Posted April 16, 2008 Share Posted April 16, 2008 I would remove the old seal, degrease the groove, fit a new seal, then inject RTV sealant or similar down the groove. Fancy drilling a groove in the hub body - TSK! Les Quote Link to comment Share on other sites More sharing options...
Gromit Posted April 16, 2008 Author Share Posted April 16, 2008 Fancy drilling a groove in the hub body - TSK! Yeah, I know Cheers, for the advice. Will give some RTV a go at the weekend. Will just have to live with the squirrelly braking till then. On the plus side, I'm becoming quite adept at stripping the hub Cheers all!

mmgemini Posted April 16, 2008 Share Posted April 16, 2008 Degrese the hub. Tinmans solder to fill it in. Nice and spoft to get a good finish on. mike Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted April 16, 2008 Share Posted April 16, 2008 Degrease thoroughly and repair with that 'instant metal' stuff, file and sand to shape afterwards.... My god that is a bodge, but it will probably work for a while... Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted April 16, 2008 Share Posted April 16, 2008 I'm a bit lost as to why you'd be drilling a hole in the oil seal? Quote Link to comment Share on other sites More sharing options...
Les Henson Posted April 16, 2008 Share Posted April 16, 2008 You drill a hole in the oil seal to check if there's any oil left in there. If there is, you just put a small self tapper in the hole. I thought everyone did this Les Quote Link to comment Share on other sites More sharing options...
Gromit Posted April 23, 2008 Author Share Posted April 23, 2008 Just an update.The repair seems to have worked. I de-greased the hub and filled the groove with chemical metal. Allowed it to cure, put a bead of RTV and pressed the seal in. 200 miles later and it seems to be holding. Thanks all Quote Link to comment Share on other sites More sharing options...
