[QUOTE="BigEd, post: 67083, member: 161"] The instructions supplied by Roy Cross for using the jig are posted below. I thought that I had already posted these but on a quick check I can't see them in this thread. I am getting ready to catch a plane for a short break to see my brother in Spain so my time is a bit limited at the moment. I may have some more clutch shoe information. While I'm away I will try to find any extra information that I may have on my laptop or in "the cloud". [CENTER][SIZE=6][B]Vincent Clutch Plunger spring setting fixture[/B][/SIZE][/CENTER] If the intention is to fit new linings, the old linings and rivets should be removed now. [SIZE=1] [/SIZE] If the existing linings are to be used then a hole to clear half inch diameter needs to be drilled through the lining of each shoe to access the screw C12. Since this hole needs to be in line with the plunger and thus tangential to the lining it is best machined with a slot drill in a milling machine. However, if only hand tools are available it is probably best to drill a pilot hole through the lining which is then opened out with a rotary file. The adjusting screw C12 and the old springs are removed and a check made to ensure that the plunger is able to move freely. New springs PD27 and OP11 are fitted and the screw C12 replaced. The clutch shoe is then located on the half inch diameter spigot in the center of the fixture. The directional arrow cast in the side of the shoe should point anti clockwise with the plunger against the three eighth diameter pillar bearing the same part number as the shoe. The shoe should now be rotated to depress the plunger against the pillar and the screw C12 screwed in or out until the five sixteenth diameter toggle link hole in the end of the shoe is approximately aligned with a similar sized hole in the fixture with the springs fully compressed. Put a dab of paint on the end of the screw to lock it in position. If you now have to fit new linings my recommendation is to forget the rivets and send the shoes and the new linings to “Saftek” and get them to bond the linings to the shoes. With a file chamfer the outer ends of the new linings before assembly. [I]Roy Cross[/I] 29.10.2007 [/QUOTE]
