(LH Bushing End) Proper Alignment of Master Links at Assembly
Incorrect rotational alignment of master links can lead to a loss of the torque that is applied to the master link bolts and loosening of the master link bolts. This can occur when a portion of the torque that is applied to secure the master link bolts is also required to rotate a poorly aligned master link part.Refer to Illustration 1.
Illustration 1 g01395445
(1) Incorrect rotational alignment of master linkCondition of Tooling
Illustration 2 g01395502
(2) Press tooling that contacts the linkTooling that contacts the link (2) should be maintained in good condition. This may require periodic machining to ensure that the surfaces that contact the track components are flat.
Illustration 3 g01395579
(3) Press (saddle)Saddle (3) should be maintained toproperly align the pins and bushings with tooling (2) at setup. A badly worn saddle (3) may require shims to be placed between the bushing and the saddle to align with tooling (2) at setup.Alignment of Tooling
Proper alignment of the tooling for the press with the track components is a critical part of the process for track assembly. Proper alignment of the track components to the tooling for the press ensures the safety of the assemblers and the quality of the assembled track.
Illustration 4 g01395905
Center a pin and a bushing in forward saddle (4), and a bushing in rear saddle (5). Refer to Illustration 4.
Apply the hold-down tool for press (6) to the components in the saddle. Refer to Illustration 4.
Move the tooling for the press inward toward the components in the saddle.
Adjust the tooling for the press to align the tooling accurately with the components in the saddle.Preparing the Master Link
Illustration 5 g01395969
Bolt the mating parts of master link (7) and master link (8) together with correct master link bolts (10) and the required number of washers to duplicate the thickness of a track shoe (9).Note: The washers that are recommended for use in this application are commonly used for mounting rollers and idlers. Refer to Table 1 for the correct master link bolts and the correct number of washers that are required to duplicate the thickness of a track shoe.
Always use both halves of the master links and bolt both halves together. This will require maintaining sufficient parts on hand.
Since maintaining spare parts for the master links will facilitate this installation, Table 5 provides the master link part numbers for D8, D9, D10, and D11.
Illustration 6 g01397227
Apply approximately 200 N m (150 lb ft) of torque to the master link bolts to secure the washers and the master link (segments) together. A standard 1/2 inch air wrench will function adequately. Refer to Illustration 6.Installation of the Master Link (Bushing End)
Illustration 7 g01397490
Align the tooling for the press. Refer to "Alignment of Tooling". Position the bolted master link on tooling (11).
