A note about the various springs used in the driver adapters for the DTT meters. The spring
for #66620 adapter is black but is smaller than any of the other springs. It is also shorter than
any of the other springs.
There have been 2 versions of the #66618 adapter supplied with the DTT-100. The spring
supplied with the current version is black and larger than any of the other springs.
Spring #66614 which is gold, or yellow, and spring #66616 which is black, have similar inside
diameters. Spring #66616 will be a larger wire diameter but may be shorter than the gold
(yellow) spring.
It is normal for the adapter to occasionally become unscrewed or disassembled during
use. Refer to the drawing below for proper assembly rather then relying on the
creativity of individuals. All ASG DTT driver adapters using springs, regardless of
torque range or size, have similar parts and will be assembled in the same order.
It may be possible to extend the life of the bearing set (#2) after a groove appears on
the two races they may be turned over to provide a fresh surface. If the balls or rollers
in the center section are damaged replace the whole assembly
Lubricate #1, #2 & #5 as needed
with molybdenum grease
Inspect the thread on #1 and #5
periodically. Make sure the thread
turns smoothly. After 2500 cycles
check for wear and replace if
needed.
Clean, inspect and lubricate #2
After
2500 cycles. Replace if bearing is
not turning smoothly.
Replace #4 after 100,000 cycles
