Item 24 - Fan Hub
If the fan bearing hub assembly is provided with a grease fitting, use a hand grease gun and lubricate the bearings with
one shot of Texaco Premium RB grease, or an equivalent Lithium base multi-purpose grease, every 20,000 miles
(approximately 700 hours).
Every 4000 hours, clean, inspect and repack the fan bearing hub assembly with the above recommended grease.
At a major engine overhaul, remove and discard the bearings in the fan hub assembly. Pack the hub assembly, using new
bearings, with Texaco Premium RB grease or an equivalent Lithium base multi-purpose grease.
Item 25 - Thermostats and Seals
Check the thermostats and seals (preferably at the time the cooling system is prepared for winter operation). Replace the
seals if necessary.
Item 26 - Blower Screen
Inspect the blower screen and gasket assembly every 1,000 hours (30,000 miles) and, if necessary, clean the screen in
fuel oil and dry it with compressed air. Install the screen and gasket assembly with the screen side of the assembly toward
the blower. Inspect for evidence of blower seal leakage.
