Ingersoll Rand — Mounting the Winch
Installation · Winch mounting
From a Ingersoll Rand service manual — check it applies to your exact model before use.
Before you start
- If mounted inverted, the motor case must be rotated to position the vent cap at the top
Procedure
- Inspect the winch for possible shipping damage before installing.
- Mount so the drum axis is horizontal and the motor vent cap is not more than 15 degrees off top vertical center.
- The winch mounting surface must be flat to within 1/16 inch (2.0 mm); shim if necessary.
- Use 5/8 inch (16 mm) Grade 8 or better mounting bolts with self-locking nuts or nuts with lockwashers.
- Tighten mounting bolts evenly and torque to 220 ft lbs (30.4 kgm) for dry thread fasteners.
- If plated, lubricated or thread locking compound is used, torque to 170 ft lbs (23.5 kgm).
- Maintain a fleet angle of no more than 1-1/2 degrees between the sheave and winch.
- Do not weld to any part of the winch.
