diesel2607 Report post Posted February 10 Hi I have a 2012 evo and after a trial today I noticed I have a fair bit of play in the swing arm if I lift the rear wheel it goes up about half an inch to an inch on would say and clunks Do you think this would be solved by changing the swing arm bearings I am grateful for any advice Quote Share this post Link to post Share on other sites
section swept 3 Trials Bikes Report post Posted February 10 Thats wheel lift and sounds more like suspension linkage wear. Swing arm play is side to side and if you had an inch play you would be wobbling about alot. Get someone to do the moving while you have a good look....its what most of us would be doing....sounds harsh but not meant to be🙂👍 Quote Share this post Link to post Share on other sites

Thanks I am sure it is the dog bones and suspension knuckle how is best to go about getting the swing arm off i will order the bearings and try and do the job myself about £70 for the bearings i have seen Quote Share this post Link to post Share on other sites
cangy1000 Report post Posted February 10 I did my 4RT recently. I got it sat on a sturdy stand, if you can strap the bike to the stand all the better. Take lots of pics on your phone as you disassemble. Good luck Quote Share this post Link to post Share on other sites
fantic240motor Report post Posted February 10 I own a 2012 300 4T and went through the same thing when I bought it last summer. If you have the bike on a stand and get someone to gently move the rear wheel up and down while you closely inspect the linkage you may find the play is in the delta link/pivot. A millimeter play there seems to translate to 10mm at the wheel. The bolt holes aren't bushed so nothing to replace other than the pivot. When I had the pivot removed I discussed bushing the bolt holes with an engineer friend of mine to reduce the tolerance to a minimum. It is possible but I needed to refit the pivot to ride the bike that weekend and I've not bothered since. New original ones are available as is a copy by CSP for around £90. I replaced all the swingarm and linkage bearings, top hats and seals including bottom shock bearing that come in the kit. They were all a little rusty but there wasn't play in any of these parts so this didn't help the rear wheel movement. Yours may be in other parts, just sharing what I found...

2stroke4stroke Report post Posted February 11 You may as well clean and grease the swingarm bearings while you're at it. However, you may well find that the lack of play there is due to a build up of crud and the bearings are siezed/rusted and need replacement. Quote Share this post Link to post Share on other sites
mcman56 Report post Posted February 11 You should definitely include checking and greasing the swing arm bearings. They don't use a lot of grease from the factory. All Balls sells a swing arm bearing kit. Quote Share this post Link to post Share on other sites

huski Report post Posted February 16 Have you tried heating it up?You can get a ton of pressure with a vice,never had to use a press yet after getting the part hot enough you have to use gloves Quote Share this post Link to post Share on other sites

huski Report post Posted February 19 You need a proper engineering workshop vice,mine has 4" wide jaws and opens about 5".Ive had it a good 30 years and it's still fine.Its worth paying out for a good one ,made by Record .Theres some on an auction website at the mo Quote Share this post Link to post Share on other sites
