1. Disassemble the waste oil pump and check for
spring
(Figure 8-11, (5))
breakage or vane
(Figure 8-11, (7))
damage when there is an
extreme drop in discharge volume. Replace
damaged components, if necessary.
2. Replace the oil seal
(Figure 8-11, (3))
if there is
excessive oil leakage from the handle shaft
(Figure 8-11, (4))
.
3. Replace the impeller if there is an excessive
gap between the impeller and the covers on
both sides of the casing. This will cause a drop
in discharge volume.
4. The hose coupling threads are coated with
adhesive when installed. It cannot be removed
from the body.
