5-2 Inspecting the waste oil pump
{1) Disassemble the waste oit pump and check for spring
breakage or vane damage when there is an extreme
drop in discharge volume, and replace
if
necessary.
(2) Replace the oil seal
if
there is excessive oil leakage
from the handle shaft.
{3}
Replace the impeller
if
there is an excessive gap
between the impeller and the covers on both sides
of casing. This wilt cause a drop in discharge volume.
(4)
The hose coupling is coated with adhesive and screw·
ed in
It therefore cannot be disassembled
