Too much technology lols.......Naaa of course it possible,but ive never seen this system on a flywheel before,only on the thousands of crappy cars Ive had to work on every year....lols.....From what i can see, the circlip issue isnt really important. Seemingly the circlip doesnt hold the plate on,it holds the nut/cam in the flywheel assy,which is not going to help with timing,infact I doubt it even needs to come out. Your really just looking to remove the cover plate so you can do your timing accurately yes?. The diagram Gizmo supplied does not show the cover plate and washer,which to me means the circlip is underneath the Cover,NOT holding it on. Have you tried to use the screws to push the Alloy housing and washer up over the nut shaft as yet? what was the result? Sorry its frustrating,as i know i can work it out if i had it in my hands. Give both ways a try and see what how it goes.
