3. Determine the thickness of the adjuster as follows.
1) Measure the thickness of the removed adjuster
with a micrometer.
2) Calculate the thickness of a new adjuster.
Calculation
TA: Thickness of new adjuster
M: Valve clearance measurement.
TO: Thickness of the removed adjuster
For intake side: TA=TO+(M–0.15) mm
For exhaust side: TA=TO+(M–0.25) mm
Select a new adjuster whose thickness is as
close to the estimated value as possible.

alphabet letter (sometimes printed) and one
numeral letter, top priority is given to the one
alphabet letter and one numeral letter.

16. Use TECH2 to rewrite injector data to ECM.
For rewriting method refer to section “Data
Programming in Case of ECM Change” of 6E 4JX1
engine driveability and emissions in this manual.
NOTE:
1) On completion of servicing, bleed air from the
engine inside fuel passage by means of the priming
pump. (The priming pump should be operated more
times than in the case of conventional engines.)
2) As air is in the oil rail, it takes more time to start the
engine. Rough idling may occur while the air is
being bled completely after starting the engine, but
it does not indicate trouble.
The air will be bled and normal engine status will be
reached while the vehicle is driven for about 5 km
or engine is operated for about 5 minutes at 1500 to
2000 rpm.
3) The injector spare part will be provided for group
number B1, B2 and B3 only.

Set the dial indicator as shown in the illustration and
measure the crankshaft thrust clearance.
If the thrust clearance exceeds the specified limit,
replace the thrust bearing as a set.
Standard : 0.04 – 0.20 mm (0.0016 – 0.0079 in)
Limit: 0.30 mm (0.0118 in)2. Main bearing clearance
1) Remove the main bearing caps in the sequence
shown in the illustration.
Arrange the removed main bearing caps in the
cylinder number order.
2) Remove the crankshaft. Remove the main
bearings.
3) Clean the upper and lower bearings as well as
the crankshaft main journal.
4) Check the bearings for damage or excessive
wear.
The bearings must be replaced as a set if
damage or excessive wear is discovered during
inspection.
5) Set the upper bearings and the thrust washers
to their original positions. Carefully install the
crankshaft.
6) Set the lower bearings to the bearing cap
original position.
