8. Retract the die by lifting up on the control handle.
(See figure 2-C)
9. Separate the collar from the tubing. Remove tooling
and return to the storage area.
USING THE DOMING DIE TO FINISH TAlLPlPE ENDS -
For a more finished look on tailpipe ends, you may use
the DOMING DIE to slightly dome the ends. To properly
do this, follow these simple steps. (See chart on page 12
for typical end finishing illustrations.)
1. Retract the swager cylinder completely by lifting the
valve handle up.
2. Install the DD-134/212 tool on the ST-1 adapter
attached to the end of the cylinder shaft.
3. Install the required HAC adapter collar around the
tubing and position within the swager clamp blocks.
4. Leave the maximum amount of tubing extended
beyond the inside edge of the adapter collar as
possible. This will keep any slight clamp marks that
may occur away from the end of the taiIpipe which
is usually exposed as it is installed on the vehicle.
(See figure 3-C)
5. Snug the collar back into the clamp blocks by gently
pushing back on the collar assembly.
6. Slowly, while depressing the valve handle down,
move the shaft forward until the tool contacts the
tubing. Be sure that the tool is centered with the
tubing.
7. Slowly, move the tool forward until the desired finish
is achieved. (See figure 1-A)
8. Retract the die by lifting up on the control handle.
Separate the collar from the tubing. Remove tooling
and return to the storage area.
USING THE HCT-214/212 - This tool is for making head-
er flanges or “collectors” on 2-1/4” and 2-1/2” pipe ends.
This eliminates the need to purchase a collector when
installing header type manifoIds. Not included in stan-
dard tooling packages.
IMPORTANT NOTE:
When making a manifold flange, it is necessary to first
install the pipe flange or clamp around the tube prior to
finishing the ends.
To properly produce a header collector using the optional
HCT-214/212 tool follow these simple steps. (See chart
on page 12 for typical end finishing illustrations.)
1. Retract the swager cylinder completely by lifting the
valve handle up.
2. Install the HCT-214/212 on the ST-1 adapter attached
to the end of the cylinder shaft.
3. Install the required HAC adapter collar around the
tubing and position within the swager clamp blocks.
4. Leave at least 4” of tubing extended beyond the
inside edge of the adapter collar. (See figure 2-A)
