LOCATI G TOP DEAD CE TER (TDC)
Locating and knowing your engines true TDC is very important, and is crucial to
engine performance. With the DELKRO Space-N-Time tool you can achieve true
TDC
, which will allow you to optimize your camshaft, breather gear, and ignition timing
to achieve maximum performance from these components.
DIAL I DICATOR METHOD WITH CYLI DER HEADS I STALLED - Using
one of the dial indicator adaptors screwed into the spark plug hole rotate the engine
clockwise until the front cylinder piston is approximately a ½” before TDC. Now install
the dial indicator into the adaptor until it gently touches the piston. Next, continue to
rotate the flywheel assemble clockwise, watching the movement of the dial indicator
needle. The dial indicator needle will continue to advance and then stop and start to
reverse its movement. True “TDC” has been achieved at the point when the dial
indicator needle has stopped its advancement and started its reversal. Set the DELKRON
Space-N-Time degree wheel to zero (0) at this time.

DIAL I DICATOR METHOD WITH CYLI DER HEADS REMOVED – Using
the cylinder hold down knobs gently secure the front cylinder to the crankcase. Install the
DELKRON Space-N-Time dial indicator cylinder bridge over the top of the cylinder with
the dial indicator installed in the bridge. Slowly rotate the flywheel assembly clockwise
until the deck of the piston contacts the dial indicator probe. Now continue to rotate the
flywheel assembly clockwise watching the movement of the dial indicator needle. The
