Big ray Posted January 20, 2012 Share Posted January 20, 2012 We have removed the pump and found that the diaphram is u/s, we have tried removing the diaphram in the usual way, i.e. pushing in against the spring and turning...... but all to no avail, are we doing something wrong, or is it just a little stiff???? Help. Quote Link to comment Share on other sites More sharing options...
Adrian Barrell Posted January 20, 2012 Share Posted January 20, 2012 They can be difficult to remove, you have to push down and then tip it towards the mounting flange to get it to unhook. Quote Link to comment Share on other sites More sharing options...
Big ray Posted January 20, 2012 Author Share Posted January 20, 2012 Thank you Adrian, we will try that, we did not want to go blindly battering on. Regards. Ray Quote Link to comment Share on other sites More sharing options...
kpu121265 Posted January 20, 2012 Share Posted January 20, 2012 If i remember rightly (the last time i did one was at the side of the road in Normandy, 2004), the diaphrapm operating 'rods' have a vertical slot cut in them, you have to push down and away so to speak - which means you need to fiddle a bit to work out where the slot is. If it is any help, i can scan and post the page from the parts list if Stu gives it back..... Ken Quote Link to comment Share on other sites More sharing options...
