bestrial Posted November 17, 2014 Report Share Posted November 17, 2014 hello I need your experiance about the different part number and the solutions (if you have something) The part number for Marzzochi is BT20000153011 and the diameter of the seal is skf 40x52 25x9,8. It is different of the older models. I can not find this here in Greece.....is this so special ? Quote Link to comment Share on other sites More sharing options...
wobblenorbed Posted November 17, 2014 Report Share Posted November 17, 2014 Can I ask why you need to change it? Some problems can be sorted by tightening the retainer spring around the neck of the seal. Make sure you clean under the seal first.( i use wonder wipes for this) Quote Link to comment Share on other sites More sharing options...
lineaway Posted November 18, 2014 Report Share Posted November 18, 2014 Think you have too many numbers. Sounds like a 40x52x8 will work fine. Quote Link to comment Share on other sites More sharing options...
bestrial Posted November 18, 2014 Author Report Share Posted November 18, 2014 I have to change because one of them destroyed from a scratch on the tube....Thanks for your tip. The numbers is on the seal and I write them as I saw Quote Link to comment Share on other sites More sharing options...
