[QUOTE="davidd, post: 23901, member: 1177"] Follow Len's advice! The timing details are in Instruction Sheet no. 6, I believe, but Len's method obviates the need for the details. Getting the marks right is only important for timing the gears the next time the chest is apart. If you press it in yourself you need to check and probably adjust the timing. Some would say that is necessary even with the cam supplied with the pinion pushed on. In general, the pushrod ends do not match well and for best results you should shape them to the followers and adjusters. You can do it with paste, I use the oil soluble paste. A Vincent man told me recently to chuck the push rod in the drill press and use a cam follower to shape it on low speed with some paste. You can do it without paste by using a diamond stone and just checking for the high spots visually with some magnafication. Keep shaping the shiny spots (high spots) until it is all shiny. This cam indexer was copied from a photo of one used at Harpers, I believe, from Peter Barker. It has two fixed pins (inner and outer) and the one in the middle is spring loaded and disappears in the base. This latter pin engages with the groove in the cam and the outer pin locates the gear in the propper relationship to the gear teeth. You can simply place a correctly indexed cam on the base and mark where the dots should be, lining up the new pinion on those marks. It may be difficult to see, but I have a Comet mark on the left side of the base. David [IMG]http://i1017.photobucket.com/albums/af300/daviddunfey/CamIndexJig.jpg[/IMG] [/QUOTE]
