jonny.k Posted January 5, 2015 Share Posted January 5, 2015 Been having problems with my sons Virus 2, It keeps eating diffs. I've replaced the centre diff (after it stripped a tooth) with a new one, That's been on a week, and now the front and rear have gone. I stripped them down and there's no oil or grease left in them, Just a silver layer of metal slime all over them. Also i've stripped the new centre diff down and that has no lube in either, (Even though the seller said it's pre lubed). So i've now got to order 2 new diffs and some lube as well,, So what lube do the Ansmann diffs use? Quote Link to comment Share on other sites More sharing options...
jordan_bench10 Posted January 5, 2015 Share Posted January 5, 2015 Team associated diff oil is the best ive found or hpi Sounds like the diffs werent shimmed properly and its ate its way through em already Quote Link to comment Share on other sites More sharing options...
Anthoop Posted January 5, 2015 Share Posted January 5, 2015 As above really... Grease will be fine in a differential but oil can change the characteristics of the diff. action and thus the handling of the vehicle. Gears in general wear quickly due to them not being meshed correctly. Quote Link to comment Share on other sites More sharing options...
Wrighty8766 Posted January 5, 2015 Share Posted January 5, 2015 If I were you I would upgrade to hyper 7 diffs, the centre one can be had on eBay for around Quote Link to comment Share on other sites More sharing options...

jonny.k Posted January 6, 2015 Author Share Posted January 6, 2015 I forgot to mention that my lad said that it seemed as if the front wheels were spinning faster than the rears, and the front tyres would wear out faster than the rears too. Could this be due to different lubes in the front and back diffs? Or possibly someone who had the Virus 2 before me, fitted different ratio diffs..

Wrighty8766 Posted January 6, 2015 Share Posted January 6, 2015 That's just how centre diffs work, you can tune it by using different viscosity oils in the centre. Is it brushless or nitro? Quote Link to comment Share on other sites More sharing options...
jonny.k Posted January 6, 2015 Author Share Posted January 6, 2015 It was Nitro, but i converted it to brushless when i bought it as a roller.. Quote Link to comment Share on other sites More sharing options...
Wrighty8766 Posted January 6, 2015 Share Posted January 6, 2015 You need to thicken the oil in the centre diff then, it will need the old grease cleaning out and then try some 60k silicone diff oil Quote Link to comment Share on other sites More sharing options...

neil.b Posted January 6, 2015 Share Posted January 6, 2015 Are you sure you have the same ratio gearing fitted front and rear? If not then it will be winding the centre diff up and prematurely wearing it out. Quote Link to comment Share on other sites More sharing options...
jonny.k Posted January 7, 2015 Author Share Posted January 7, 2015 I don't know if they are the same ratio yet, I haven't counted the teeth. I did wonder that myself. Thanks for the links folks, those Hyper spares are cheaper than the Ansmann virus ones... Quote Link to comment Share on other sites More sharing options...

Thanks for the links folks, those Hyper spares are cheaper than the Ansmann virus ones... they are also much better quality and durability Edited January 7, 2015 by Wrighty8766 Quote Link to comment Share on other sites More sharing options...
jonny.k Posted January 8, 2015 Author Share Posted January 8, 2015 Do the Hyper diffs come pre shimmed and pre lubed? Quote Link to comment Share on other sites More sharing options...
Wrighty8766 Posted January 8, 2015 Share Posted January 8, 2015 Do the Hyper diffs come pre shimmed and pre lubed? They come greased but not shimmed, to be honest they don't really need re shimming, I have ran standard hyper diffs on 4-6s brushless for 12+ months without any issues The minimum thing you will get away with doing is cleaning out the centre diff and filling it with 40-60k diff oil, just make sure it all turns freely without any notchyness Quote Link to comment Share on other sites More sharing options...
SirusDviruS Posted January 11, 2015 Share Posted January 11, 2015 The diff in my virus 2 (bought new) were bone dry, luckily I stripped it down after running in and filled with diff oil. I had no further problems after that. Naughty of annsman really. Quote Link to comment Share on other sites More sharing options...
