ARM ASSEM. (INLET) 7W7556 - Caterpillar

All Engines In All ApplicationsDescription of Change: A nylon seal is now used in place of the former aluminum seal to seal all critical components, such as governors, fuel systems, timing access bolts, etc. The 8S7115 Lockwire is still used. The nylon seal is self-locking and secures the ends of the lockwire. See illustration. The wire in the aluminum seal could be pulled out of the aluminum and reinserted in the seal if the seal was not tightly crimped. This nylon seal is installed by Caterpillar at all factories. It is yellow and has CAT imprinted on the seal. See first chart.
New, nylon self-locking seal for critical areas. No dealer or customer's code is on seals installed at the factory.Adaptable To: NACD Dealers Only. The new seal(s) and the 8S7115 Lockwire can be used as direct replacements for the former seal and lockwire. No sealing tool is required. Simply put both ends of the 8S7115 Lockwire in both grooves around the arrow-shaped lock, and push the lock firmly inside the seal cavity. See illustration. Part numbers of the former seals and sealing tools are listed in the chart.
