Usage:
PR-1000 (5XC) Cold Planer
Description of Change: A new exhaust valve with a chrome-plated stem has replaced a former exhaust valve on the above machine. The new chrome-plated stem increases the wear life for the valve and cylinder head valve guide.
Illustration. 119-6772 Exhaust Valve: (A) Weld joint. (B) Length is chrome-plated.
Adaptable To: The new 119-6772 Exhaust Valve with chrome-plated stem cancels and replaces former 9N-5125 Exhaust Valve within 7C-0106 Cylinder Head Group.
NOTE: The chrome-plating (length "B") is visible on the stem. However, the plating hides the weld joint (A) between the chrome-nickel alloy head and the steel stem. The head, facing, and stem on the new exhaust valve are made of the same materials as for the former exhaust valve.
The PR-1000 (5XC) Cold Planer is powered by the 3208 (79V) Engine that has valve guides machined into the iron cylinder head casting. The 119-6772 Exhaust Valve is effective with the 3208 (79V25097-Up) Engine and adaptable to first production of all earlier 3208 (79V) Engines.
