Year
Volvo Engine
Adjust valves on the VE D7C and the D12 engine every
12 months, regardless of mileage. Preadjust the D7C
engine initially at 6 to 8 months. Preadjust the D12 at 3
months. See engine manual for specifications and
procedures.
Every:
Two Years
Engine Coolant
Engine coolant needs to be changed every two years
unless the maximum mileage has been reached before
that. See specification section for each engine manufac-
turer’s mileage recommendation.
Caterpillar: Coolant Extender Added
If using long-life coolant in a Caterpillar engine, add
coolant extender every second year.
Clutch Hydraulic Fluid
Change the hydraulic fluid in the hydraulic system for the
clutch. The clutch hydraulic system fluid collects moisture
from the air and will eventually hold enough moisture to
affect the metal surfaces in the system unless removed.
Drain fluid by removing the lid for the fluid container and
then drain through the bleed fitting on the clutch slave
cylinder into a container.
Use bleeder tool 999 6928 to refill the hydraulic system
with new fluid. Use fluid to specification DOT 4.
Fan Hubs
Check clutch lining condition and thickness every
80,000 km (50,000 miles). Use lining wear gauges
where applicable.
Inspect engagement mechanism for air leaks.
Every:
Two to Three Years
Air Dryers
The exchange interval of the air dryer cartridge is heavily
dependent on how often the compressor cycles off and
on and if the climate is hot and moist or cool and dry.
Do not use a dryer cartridge for more than three years. It
may have to be changed before that. If a lot of fluid is
collecting in the wet tank, then the desiccant in the dryer
may be saturated and needs to be changed.
