FUEL FILTER
Air Bleeding
EBS00BLB
After fuel filter is replaced and after fuel system components are
removed/installed, bleed air from fuel path as follows:
1. Move priming pump up and down to bleed air from fuel path.
2. When air is bled, pumping of priming pump becomes heavy stop
operation at that time.
3. Crank the engine until it starts. Do not crank the engine for more
than 30 seconds.
4. If the engine does not starts, stop cranking and repeat step 1
above.
5. If the engine does not operate smoothly after it has started, race
it two or three times.
6. If air cannot be bled easily (pumping of priming pump does not become heavy), disconnect feed-side of
hose between fuel filter and electronically controlled fuel injection pump. After that, operate priming pump
and confirm that fuel comes out.
CAUTION:
Prepare a tray to collect fuel. Prevent fuel from adhering to rubber parts, especially the engine
mount insulator.
Draining Water from Fuel FilterEBS00MRU
1. Prepare a tray at the drain hose open end.
2. Loosen drain cock, and operate priming pump to drain water
from fuel filter.
CAUTION:
●Water in filter is drained with fuel. Prepare larger capacity
pan than fuel filter volume.
●Drained water is mixed with fuel. Prevent fuel from adher-
ing to rubber parts such as engine mount insulator.
3. After draining, close drain cock by hand.
CAUTION:
If drain cock is tightened excessively, it may be damaged
and fuel will leak. Do not use tools to tighten drain cock.
4. Bleed air in fuel piping. Refer to FL-16, "
Air Bleeding" .
5. Start engine and check for fuel leakage.

CLUTCH AND BAND CHART
●*1: Operates when overdrive control switch is set in “OFF” position.
●*2: Oil pressure is applied to both 2nd “apply” side and 3rd “release” side of band servo piston. However, brake band does not con-
tract because oil pressure area on the “release” side is greater than that on the “apply” side.
●*3: Oil pressure is applied to 4th “apply” side in condition *2 above, and brake band contracts.
●*4: A/T will not shift to 4th when overdrive control switch is set in “OFF” position.
●: Operates.
●A: Operates when throttle opening is less than 3/16, activating engine brake.
●B: Operates during “progressive” acceleration.
●C: Operates but does not affect power transmission.
●D: Operates when throttle opening is less than 3/16, but does not affect engine brake. Shift positionRever
