Dampner out of wack

I'd be interested to hear how you used your dial indicator. You cannot just "look for" the highest point of the piston, as it's nearly stopped for a few degrees at TDC

What you must do is use the indicator the same way as you would a piston stop.........that is, stop the piston at an arbitrary point BTDC, mark the damper, then stop the piston on the way down at the same height ATDC and make a second mark. Your true TDC is halfway between the marks

If you are simply looking for "highest point" with an indicator it could easily be "off" that far by your method.

Also, it just might be that the piston rocking a little in the bore will add a tiny amount of "Murphy" into the equation..............

Yes, I am going to do the 30 degree stop on both sides of the dampener and see where it lands. I do not have a timing tape. What can you suggest as a measuring device between the two marks?

I have very little overlap showing on the dampener but from what I am reading the dial indicator isnt accurate enough to show the correct amount of overlap.......this has me confused...... a precision measuring device that is showing me ( in the thousands of an inch ) the amount of overlap as I look at the dial isnt accurate enough?

I can literally see the dial indicator rise with the piston, I can see the overlap with the dial indicator ( and it is very minute ) and of course I can see piston drop.

Again I will put together the piston stop/set up the dial indicator as you suggest and measure it this way over the weekend at the latest ( cause what do I know ) but I am going to be shocked if it shows me a different location on the dampener than what I have showing here now.

Suggestions on a temp. timing tape would be appreciated.

I guess maybe I need to invest in one of those stick on deals but for the time being I do not have one.
