size=2 face=Arial>I am surprised with the number of comments this topic has
attracted. I am in the process of rebuilding a 29D series AH 3000 engine and
purchased vernier cam gears from AH Spares some months ago. The engine is not
finished yet but the AH Spares cam gears are well made and I thought I would
list the reasons why I bought them. My situation might not apply in all cases
but it is one perspective:</FONT></SPAN></DIV>

<DIV dir=ltr align=left><SPAN class=041513615-08072017><FONT color=#0000ff
size=2 face=Arial>The engine was in poor condition and is undergoing a full and
complete rebuild but every indication is it led a hard life and was not well
cared for. The condition of the original cam chain and gears was unknown
and new replacement parts are not expensive compared to the cost of the
rebuild.</FONT></SPAN></DIV>

<DIV dir=ltr align=left><SPAN class=041513615-08072017><FONT color=#0000ff
size=2 face=Arial>The original cam has been reground to the BJ8 profile which
changes the duration and the lift. Once the cam is changed or modified vernier
cam gears are almost a must to get accurate cam timing no matter what the
desired timing is.</FONT></SPAN></DIV>

and this will affect the valve timing as well.</FONT></SPAN></DIV>

size=2 face=Arial>The professional engine builder I am working with has rebuild
many AH engines and can attest to the benefits of optimising the cam timing
which can only be done with adjustable gears. My car will be a daily driver but
will have more HP than stock.</FONT></SPAN></DIV>

[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><BR><BR>_______________________________________________<BR>Support
