How to measure primary chain deflection
Today, I did the complete 5,000 mile maintenance myself. But for what I learned on this forum, I would have never attempted it. Thanks.
I was a bit miffed as to accurately measuring primary chain deflection. I used a steel ruler and marked where it met the primary case, then pushed up. I measured acceptable deflection that way, but I'm sure it's not as accurate as it could be.
Does anyone have a handy way to accurately measure this or do I need to buy the tool from Harley?
Thanks,
JBB

I made this tool for my softail which has the elongated primary chain hole in the cover out of 1/2 wide bar stock, If you have a touring bike , then you would have the large square opening so the tool would have to be marked differently with the scribe marks. It makes the operation such an easy thing to do. All you do is to insert it in the hole and lift up the chain with the tool using the scribe marks at the 5/8 or 7/8 depending if it is hot or cold and line the marks up with the top of the opening in the cover. I hope you can make out the markings on it.
