200 BENCH PROCEDURES
Page 5-3
When the entire block must be counterbored, cut
the deepest bores first. This way, the tool can be
adjusted to the lowest depth and used for all
cylinders, ensuring uniform depth on all cylinder
counterbores.
3. Position the tool in the cylinder bore by
backing the depth-set collars (5 and 16) off
and lowering the cutter plate (13) into the
counterbore to center the tool.
4. Secure the cutter plate to the cylinder block
with four M16 x 2 x 90 hex-head capscrews
(3) and special washers (4) from the
counterbore tool kit PT2210.
5. Cross-torque the capscrews to 30 lb-ft
(41 N
폷
m) using torque wrench J 24406 or
equivalent.
Lift T-handle (2) slightly (so cutter plate is not in
contact with the counterbore) and rotate the
mainshaft (15) counterclockwise to ensure cutter
plate turns freely without binding. If necessary,
loosen the capscrews and relocate the tool.
6. Using the counterbore tool T-handle (2),
raise the cutter plate approximately 1/2 inch
(12.7 mm) from the counterbore ledge.
7. Using hex key wrench PT2210-14 (18), turn
the cutter bit adjusting screw (10) clockwise
until the cutter bit contacts the counterbore
ledge. Do not touch the counterbore wall.
8. Back off the lower depth-set collar (16) and
lower the cutter plate until the cutter rests on
the ledge.
9. Rotate the lower depth-set collar down until
the collar contacts the main housing.
10. Rotate the collar an additional five
increments: 0.005 inch (0.127 mm). Each
graduation of the collar is one-thousandth
(0.001) of an inch (0.025 mm). This will lift
the cutter bit 0.005 inch (0.127 mm) off the
counterbore ledge, allowing an accurate
setting of the cutter bit.
It may be necessary to use a flashlight to see the
cutter bit adjusting screw.
11. Using hex key wrench PT2210-14 (18), turn
the cutter bit adjusting screw clockwise until
the cutter bit rests on the counterbore ledge.
12. If the cutter bit will not adjust, adjust the
lower depth-set collar (16) 0.005 inch
(0.127 mm) more and recheck cutter bit
hold-down screws for looseness.
13. Zero the depth-set collars:
a.
Back off the lower depth-set collar (16)
and carefully lower the cutter plate (13)
into the bore and allow the cutter to rest
on the counterbore ledge.
b.
Rotate both depth-set collars (5 and 16)
down until the bottom collar contacts
the main housing (8).
Do not force the collar beyond this point, as it will
lift the cutter plate and prevent an accurate zero
reading.
14. Set the depth of the cut. Determine the final
depth of the cut and back off the top depth-
set collar accordingly. Each increment on
the depth-set collar increases the depth of
the cut by one-thousandth (0.001) of an inch
(0.025 mm). Tighten the thumbscrew (17) on
the upper collar (5) securely.
