Problem:
Misalignment between the 155-0488 Crankshaft Pulley, the 133-7022 Idler Pulley and the two 7E-4839 Pulleys is causing the 162-2742 Belt to fail prematurely.
Solution:
The alignment of the pulleys should be checked and corrected if not within specification.
Illustration 1.
Verify that the grooves of belt (1) are properly seated in the grooves of crankshaft pulley (2). Use a strait edge (X) to check the alignment of crankshaft pulley (2). The outside face of crankshaft pulley (2) should be flush with the outside face of stub shaft (3) within ± 0.05 mm (± 0.02 inch). If crankshaft pulley (2) is found to be out of alignment with stub shaft (3), use the appropriate size and number of washers to correct the alignment.
Illustration 2.
Verify that the grooves of belt (1) are properly seated in the grooves of idler pulley (4). Use a straight edge (X) to check the alignment of idler pulley (4) with stub shaft (3). If idler pulley (4) is found to be out of alignment with stub shaft (3), use the appropriate size and number of washers to correct the alignment.
Illustration 3.
Verify that the grooves of belt (1) are properly seated in the grooves of pulley (5). Use a straight edge (X) to check the alignment of pulley (5) with stub shaft (3). If pulley (5) is found to be out of alignment with stub shaft (3), use the appropriate size and number of washers to correct the alignment.
Illustration 4.
Verify that the grooves of belt (1) are properly seated in the grooves of pulley (6). Use a straight edge (X) to check the alignment of pulley (6) with stub shaft (3). If pulley (6) is found to be out of alignment with stub shaft (3), use the appropriate size and number of washers to correct the alignment.
