Just a warning if you use one of these tool kits. JCNA's tool program has everything for loan except the cam locking bars, so I purchased the kit pictured here for about $45 delivered. Everything worked fine until I went to tension the chains when I noticed some cam rotation. It turned out the bosses on the bars were too long to totally lock the cams down, allowing a few degrees of rotation. I simply ground these down to .600" (from the underside of the bar to the bottom of the boss) - this got everything locked down properly. Recommend you check this measurement before disconnecting the timing gear if you use this tool.

 

What would be the correct measurement/height on the studs in order for the tool to firmly hold on to the cams?

Thanks for the tip. I'm waiting on this tool to replace chains etc on my XK8

 

E - I'm not certain I understand your question. The vertical distance from the bottom of the bar/flats on the cams to the plane of the head surface the tool bolts to is .600". That's the length of the bosses on the tool I mentioned above - I had to remove 15 thousandths (.015") from the bosses to get the tool to work properly. Hope that answers your question.

 

Thank you Doug, it was what i meant.. now i can doublecheck the measurement on my own tool. :-)
