* Please consult LORD engineering for application review,
approval and availability.
Prolonged exposure to temperatures in the 0°F range and
below produces a signifi cantly reduced slip torque prior to
driveline warm-up. This condition may result in the coupling’s
inability to transmit adequate drive torque for applications
experiencing unusual cold temperature related parasitic
loading.
Blind assembly style with a notched periphery provides
trouble-free, sliding assembly on fl ywheel drive pins when
bolted access is not possible. Outer member is a composite
material.

Bushing type SK or equivalent.
See detail drawings by part number for tolerances.
Pilot diameter tolerances are + .000/ -.005 in for -A Series
diameters and + .005/ -.000 in for -C Series diameters.
Tapered.
Refer to SAE J620c for fl ywheel numbers 6-1/2, 10, 11-1/2,
16; to SAE J927a for numbers 60, 80, 100, 120, 160. See
Tables 5 and 6.
Unless otherwise noted:
.xx dim ± 0.030 in (± 0.762 mm)
.xxx dim ± 0.015 in (± 0.381 mm)
It is advisable to refer to drawing of coupling before
ordering since it is not practical to show all details in this
