An Extension Assembly Arm is used during service procedures to remove and install the final drive assembly into the track roller frame. It is used with an overhead hoist or equivalent lifting device, allowing the final drive and extension arm to be lifted and positioned as a single controlled unit. The arm supports holding the final drive assembly in a horizontal position, which is required due to close tolerances between the mounting diameters and the track roller frame bores.Attributes:• Supports removal and installation of the final drive.• Extra mounting holes allow the final drive to be rotated to any desired angle.• Maintains stable positioning during alignment work.Applications: An Extension Assembly Arm is used to lift, remove, and install the final drive assembly into the track roller frame, maintains horizontal alignment during handling to support accurate installation at the mounting location.
