I sent the email below out a little while back, just wondering if anyone has any advice? Thanks Rob _____________________________________________ From: Rob Jarratt [mailto:robert.jarratt at ntlworld.com] Sent: 23 July 2011 21:25 To: General Discussion: On-Topic and Off-Topic Posts (cctalk at classiccmp.org) Subject: RD53 Stiction I have an RD53 which is suffering from the sticky bumper problem. Normally I can resolve this with a sliver of paper placed over the sticky bumper. But in this instance it seems the bumper has practically liquefied and I think it has gummed up some of the mechanism. Is it feasible to dismantle the assembly to clean it up? Has anyone ever done this? Any advice? Thanks Rob
