New Oil Cooler And Hose Improves Routing{1374}

Usage:

416B (8SG, 8ZK),
426B (5YJ),
428B (7EJ),
436B (6MJ),
438B (3KK) Backhoe Loaders

Description of Change: A new oil cooler and hose are used. The inlet on the new cooler is now located closer to the edge of the cooler and requires the use of a new hose. The new hose is shorter to accomodate the new cooler. The location of the new inlet and hose change is to improve reliability by providing better routing.

Adaptable To: The new 119-6254 Oil Cooler Core Assembly is a direct replacement for the former 4P-3382 Oil Cooler Core Assembly. The new cooler assembly requires a new 117-8263 Hose Assembly which replaces the former 9R-9096 Hose Assembly.

This change is effective with 416B (8SG5130, 8ZK2236), 426B (5YJ1429), 428B (7EJ2641), 436B (6MJ621), 438B (3KK1086) Backhoe Loaders and is adaptable to all earlier machines.
