The oil filter is a small, full-flow cartridge type and is provided with a
relief valve.
●
When changing oil filter, refer to
Oil Pump Inspection
EBS00GUL
Using a feeler gauge, check the following clearances after the pump is disassembled.
Standard clearance:
Unit: mm (in)
●
If the inner rotor tip clearance (1) exceeds the limit, replace
rotor set.
●
If pump body to outer rotor clearance and side clearance (2)
or (3) exceed the specification, replace oil pump assembly.
