Introduction

The 142-1664 Adjustable Lifting Bracket Group is a "C"-style lifting device. The lifting bracket is used to remove and install heavy parts and assemblies for a wide variety of applications.

The following features provide maximum versatility:

• Internal threaded rods adjust extension arms to achieve center of gravity.

• Asymmetrical, adjustable lifting bracket can be oriented with either arm in the upright position.

• Additional adapters increase versatility and eliminate the need for multiple lifting brackets.

• 151-2816 Handling Plate (6), 2H-3744 Grade 8 Bolts (2 qty) (7), and 5P-8250 Washers (2 qty) (8) are required to attach the lifting shackle to extension arm (2) .

NOTICE
Failure to follow the instructions or heed the warnings below could result in injury or death. Verify that the load to be lifted does not exceed the specified capacity. Measure the length of extension at A and B, and match with the chart. Always use the lower of the two capacities. Always adjust the arms to the shortest usable length. Refer to the service manual for specific applications. Do not adjust under load. Inspect the condition of the lifting bracket group prior to use. Lubricate as necessary.

Optional Adapters

Optional adapters can be used to make this tooling more versatile.

Hardware used to attach adapter plates and bracket assemblies must meet or exceed 10.9 Metric or Grade 8 (English) specifications. Always use hardened flat washers, and tighten all hardware to the correct torque value for the fastener size.
