Repair Instructions

Transfer Oil Level Check

S5JB0A3316033

1) Lift up vehicle and check oil leakage.
2) Remove oil level/filler plug (1) and check oil level is 

between 0 and 10 mm (0 and 0.394 in.) from the 
lower end of oil level / filler plug hole (2).
If oil level is not in the range, add specified oil up to 
plug hole.

Transfer Oil Change

S5JB0A3316034

1) Before changing or inspecting oil, be sure to stop 

engine and lift vehicle horizontally.

2) Check leakage.

If leakage exists, correct it.

NOTE
Whenever vehicle is hoisted for any other 
service work than oil change, also be sure to 
check for oil leakage.

 

3) Remove oil filler plug (2).
4) Remove drain plug (1), and drain oil.
5) Apply sealant to thread of drain plug (1), and tighten 

it to specified torque.

“A”:  Sealant 99000–31260 (SUZUKI Bond 
No.1217G)

Tightening torque
Transfer oil drain plug (a):  23 N·m (2.3 kgf-m, 
17.0 lb-ft)

6) Pour new specified oil up to lower end of oil level / 

filler plug hole (3).

NOTE
It is highly recommended to use API GL-4 
75W-90 gear oil.

 

Transfer oil specification
: API GL-4 (For SAE classification, refer to 
viscosity chart [A] in figure.)
