Bearing
Make sure the bearings roll freely and are free from noise, pit-
ting and cracks.
Main Oil Pump
1. Check the inner and outer circumference, tooth face, and side-
face of the inner and outer gears for damage or abnormal wear.
2. Measure the side clearance between the main oil pump housing edge and the inner and outer gears.
3. Make sure the side clearance is within specification. If the mea- surement is out of specification, replace the inner and outer
gears with new ones as a set. Refer to TF-165, "
Main Oil Pump"
.
Sub-oil Pump
1. Check the inner and outer circumference, tooth face, and side-
face of the inner and outer gears for damage or abnormal wear.
2. Measure the side clearance between the sub oil pump housing edge and the inner and outer gears.
3. Make sure the side clearance is within specification. If the mea- surement is out of specification, replace the inner and outer
gears with new ones as a set. Refer to TF-165, "
Sub-oil Pump" .
Control Valve
Check resistance between the terminals of the clutch pressure
solenoid valve, 2-4WD shift solenoid valve, clutch pressure
switch, line pressure switch and the transfer fluid temperature
sensor. Refer to TF-90, "
COMPONENT INSPECTION" (clutch
pressure solenoid valve), TF-94, "
COMPONENT INSPECTION"
(2-4WD solenoid valve), TF-107, "COMPONENT INSPECTION"
(clutch pressure switch), TF-110, "COMPONENT INSPECTION"
(line pressure switch) and TF-104, "COMPONENT INSPEC-
TION" (transfer fluid temperature sensor).
