*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.

Use Wood’s Sure-Grip®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 catalog.
