Subject: [Healeys] Vernier timing gears<br>
<br>
Hello,<br>
<br>
I am getting back to my Healey 3000 engine rebuild after two <br>
years. I bought the Roller master vernier timing gear set from
Moss at <br>
that time. I have previously used the Roller Master gear set
with <br>
multiple key ways to adjust the cam timing with no problems on
other <br>
rebuilds. What I don't like about this set is that the cap
screws used <br>
to clamp the vernier gear to the hub are not very robust.
Working in <br>
aviation I have AN-4 bolts that I can replace the cap screws
with and <br>
safety wire them to prevent slippage. Has anyone using this
kit had <br>
problems? I could keep the cap screws and Loctite them. This
is a <br>
street car, not a race car. Pictures are one bolt installed
and the <br>
hardware side by side.<br>
<br>
Wayne<br>
