stuessenhigh Posted July 10, 2005 Report Share Posted July 10, 2005 I THINK some people just buy a new "dog-bone" with the bearings in it already dont they??...I heard its not TOO mUCH more..and the dog bone is often bashed about which makes getting them out even harder??

charliechitlins Posted July 10, 2005 Report Share Posted July 10, 2005 Heat the dogbone and tap the bearing race out using a socket (as close to the size of the hole as possible) and a hammer. I sit them atop a bench vise and open the jaws enough to leave room for the bearing to come out the bottom. Quote Link to comment Share on other sites More sharing options...
beta boy Posted July 11, 2005 Author Report Share Posted July 11, 2005 (edited) i take it the needles arent suppost ot fall out i must off been cause they where very worn and rusty. my dog bones dont have a scratch on em dont think the bike has ever been used on rocks the bash plate is in very good condition Edited July 11, 2005 by beta boy Quote Link to comment Share on other sites More sharing options...
charliechitlins Posted July 11, 2005 Report Share Posted July 11, 2005 Right. It's not impact. If they get dry and crusty enough, they will just drop out. Fortunately, after doing them once or twice, you'll be able to service them quickly. By the 3rd time, you should have it to about 30 minutes.

pandelboy Posted July 11, 2005 Report Share Posted July 11, 2005 Get a larger socket than the outside diameter of the bearing and another that will fit through the dog bone where the bearing sits and push the old bearing out. put the whole assembly into a vice and press the old one out and use the same procedure to put the new one back in, cushty!!! nice and carefull as they are soft cage bearings. Use water resistant grease when putting everything back together. ps... it helps if two people are involved one to hold the lot still in the vice to start and then the other to operate the vice.

neonsurge Posted July 11, 2005 Report Share Posted July 11, 2005 i take it the needles arent suppost ot fall out i must off been cause they where very worn and rusty. Sounds like my old '99 270TXT. When I stripped it all down to grease everything up, the linkage bearings (and bushes) just disintegrated into rusty dust when I removed the bolts. Guess that accounted for the 20mm of play in the rear suspension! Rather than wrestle with pressing new bearings into the old dogbones etc., I bought a new pair of dogbones with the bearings already installed. Including assorted other linkage bits and pieces it cost around Quote Link to comment Share on other sites More sharing options...
jtt Posted July 11, 2005 Report Share Posted July 11, 2005 I also use pandelboy's "vise-press" method. It's nice and smooth and you can use the same technique to press in the new one. I have an alergic reaction to hammers Quote Link to comment Share on other sites More sharing options...
elvis Posted July 11, 2005 Report Share Posted July 11, 2005 When I changed them on my 02 sherco I took the bearing to a local bearing company where they made me new ones and also supplied the sleeves to match. Not sure how much they would cost from gasgas but if I remember correctly I paid only a few pounds for both bearing and sleeve. Hope this may save you a few quid Quote Link to comment Share on other sites More sharing options...
