Adam, The "this is fixed line" needs to come up to the top of the insulator - the other lines are correct. The insulator doesn't move much but it does move under heavy load and acceleration/deceleration and more so when everything is hot under the bonnet, and the movement will increase slightly as time goes by. It passes the index finger test so it is fine. I would wait until you get it going and then worry about it if it touches - removing the dump to get the mount out would be the only pain.

Hi Terry, I had a look today and i can only just fit my index finger inbetween and once the mount is ground back then there will be a little less room One thing I find a little puzzling is how will these parts come into contact? I've made an image below with lines and text according to what I think moves together - please correct me where i'm wrong. http://sr510.com/gfy/no_fit_text.jpg cheers, Adam ----- Original Message ----- From: "Terry Rudd" <[EMAIL PROTECTED]> To: <[email protected]> Sent: Thursday, June 15, 2006 5:09 AM Subject: RE: shaving the engine mounts? > The top angle photo indicates there isn't a problem as the housing > looks > to > be in a different plane to the mount - Ok, then I looked at the "another > angle" pic and it looks like it could be a problem just like it did in the > first photo - I think visual is the go here.
