Note: The 1U-9600 Welding Group (60 Hz) is not sold in Europe. The 1U-9601 Welding Group (50 Hz) is sold in Europe only. The 1U-9601 Welding Group (50 Hz) can replace the 1U-9600 Welding Group (60 Hz).
5. Apply weld (A) to each of the pin bore. Refer to Illustration 1 in Image1.8.1.
Note: Before you begin to weld on the pin bore, preheat the metal to 95 degrees Celsius (203 degrees Fahrenheit).
6. Apply multiple welds (B) to the length of the pin bore. The welds must connect the welds which outline the pin bore. Refer to Illustration 1 in Image1.8.1.
Note: Allow the welds to slowly cool. Repair any welds by removing the existing weld. Apply a weld to the area which is being repaired. Before you begin welding again, you must preheat the pin bore.
7. Machine the welds to the dimensions shown below according to the model.

Protecting the Welds:
New welds must be painted. Paint will protect the welds against rusting. Paint the welds with an authorized Caterpillar paint. The paint will help prevent rust from forming on the new welds. Refer to the following instructions for preparing the welds for painting and for painting the welds.
Finishing the Welds and Painting the Welds:
1. Protect all finished bores. Cover the bores in order to prevent paint and other material from entering the bores.
2. Grind all the welds to a smooth finish.
3. Remove any spatter from the surrounding areas around the welds.
4. Shot blast the welds and surrounding areas prior to painting.
5. Paint the welds with a paint that is approved by Caterpillar.
6. Remove all protective outer coverings from the bores.
7. Inspect the grease passages for obstructions before you install new bearings. If the grease passages become blocked, the grease which is used to lubricate the bearings will not reach the bearings. Failure to lubricate the bearings will result in damage to the bearings.
