TomB Posted February 4, 2013 Share Posted February 4, 2013 Just a quick couple of vernier questions prior to changing the timing belt. 1) Should I 'zero' the vernier callipers so that there is no camshaft adjustment, change the belt and reset them by just turning the cams to where they were prior to disassembly, or do I need to borrow the dial gauges etc and retime them? or 2) Can I simply lock the pulleys with the cam locking tool and reassemble without messing with the timing? or 3) is it so easy to check the adjustment, its worth doing anyway while Im doing the belt to make sure they havnt slipped?

Mankee Posted February 4, 2013 Share Posted February 4, 2013 Hi Tom. This topic cropped up recently: http://blatchat.com/t.asp?id=225657 What cams are you running? I found that even totally standard cams benefitted from some timing tweaks after changing the belt and fitting verniers. Link to comment Share on other sites More sharing options...
TomB Posted February 4, 2013 Author Share Posted February 4, 2013 Hi Mankee, Im running the standard Supersport cams, and the verniers are already fitted. Im just wondering if there are any special considerations beyond those in a Haynes or similar manual where standard pulleys are assumed, where Verniers are fitted. Thanks for the link, more or less answers my query Edited by - TomB on 4 Feb 2013 13:49:35 Link to comment Share on other sites More sharing options...
Leadership Team SLR No.77 Posted February 4, 2013 Leadership Team Share Posted February 4, 2013 Tom, check the timing, change the belt, re-check the timing and adjust as necessary. I have gauges and mounting brackets if you want to borrow them. Stu. Link to comment Share on other sites More sharing options...

John Vine Posted February 4, 2013 Share Posted February 4, 2013 Well, if all you really want (or need) to do is change the belt, your option #2 will work just fine. But if you want to be sure that the timing is as good as it can be, do the before/after checks as well. If you're ever down Dorset way, I could lend you the dial gauges and mounts I used when I fitted verniers to my old SS-R. JV Link to comment Share on other sites More sharing options...
Englishmaninwales Posted February 4, 2013 Share Posted February 4, 2013 Tom Method 2 will 'do' but the crank cambelt sprocket is a lousy fit and you will loose the 'exact' timing that you had prior. If you want to borrow my dial gauges and mounts to do the job or bring your car here just let me know. Malcolm Link to comment Share on other sites More sharing options...
