Indexing in this case means aligning the crankshaft in the grinding =
machine so that as the crank is rotated, the journal center is the =
center of rotation. In a four cylinder triump crank journals two and =
three, and journals one and four are in the same plane. So the grinder =
aligns the machine so 1 and 4 are concentric, grinds those two, then =
indexes 2 and 3, and grinds those. In a six there are three sets of =
concentric pairs. Any indexing error means the two journals ground with =
error may reach TDC at a different degree of crank rotation (offset =
horizontally to the main journal plane), or at a different height above =
the center of crank rotation (offset verticallly), or both.=20

SUBJECT: Re: [Fot] TR6 Piston / Head Clearance<br class=3D"">&gt; Hi,<br =
class=3D"">&gt; Where I was going with the query was this: I had a<br =
class=3D"">late block<br class=3D"">&gt; "decked" with the intent of =
making the deck flat.<br class=3D"">The machinist took<br class=3D"">&gt; =
of .032 to accomplish the goal. With a head gasket<br class=3D"">installed=
 and the<br class=3D"">&gt; head torqued, the clearance in the squish =
area is .030.<br class=3D"">&gt;<br class=3D"">&gt; I had initially =
wanted only about .025 removed, but<br class=3D"">we had to shave<br =
class=3D"">&gt; an extra .007 to get rid of the fire ring cuts.<br =
class=3D"">&gt;<br class=3D"">&gt; On initial startup, the motor sounded =
like it might<br class=3D"">be "rattling" and<br class=3D"">&gt; I'm =
trying to figure out why.<br class=3D"">&gt;<br class=3D"">&gt; When I =
used a stethescope on the block, everything<br class=3D"">sounds okay - =
no<br class=3D"">&gt; rapping and the valve train sounds "normal" and<br =
class=3D"">there were no weird<br class=3D"">&gt; sounds coming from the =
crank.<br class=3D"">&gt;<br class=3D"">&gt; I guess where I'm going =
with this is: if piston /<br class=3D"">head clearance is<br =
class=3D"">&gt; too tight, I'll see some sort of indication on the<br =
class=3D"">piston, right?<br class=3D"">&gt;<br class=3D"">&gt; TIA for =
any sage advice.<br class=3D"">&gt;<br class=3D"">&gt; This is my first =
experience "decking" a block. I'd<br class=3D"">like to get it<br =
class=3D"">&gt; right, I don't have the resources to start a new<br =
class=3D"">block from scratch.<br class=3D"">&gt;<br class=3D"">&gt; =
