OIL FILTER WRENCH

B: INSTALLATION

1) Apply a thin coat of ATF to the oil seal part of
new ATF filter.
2) Install the ATF filter. Turn it by hand, being care-
ful not to damage oil seal.
3) Tighten the ATF filter using ST.
Calculate the ATF filter tightening torque using fol-
lowing formula.
T2 = L2/(L1 + L2) × T1
T1: 14 N·m (1.4 kgf-m, 10.3 ft-lb)
[Required torque setting]
T2: Tightening torque
L1: ST length 78 mm (3.07 in)
L2: Torque wrench length
Example:

NOTE:
Align the ST with the torque wrench while tighten-
ing the ATF filter.
