22. Install knock sensor.
● Install knock sensor so that connector faces front of engine.
● After installing knock sensor, connect harness connector, and
lay it out to rear of engine.
CAUTION:
● Do not tighten mounting bolts while holding connector.
● If any impact by dropping is applied to knock sensor,
replace it with new one.
NOTE:
● Make sure that there is no foreign material on the cylinder
block mating surface and the back surface of knock sensor.
● Make sure that knock sensor does not interfere with other parts.
23. Install followings in reverse order of removal.
How to Select Piston and Bearing ABS00FPI
DESCRIPTION
*For the service parts, the grade for fitting cannot be selected between a piston pin and a connecting rod.
(Only 0 grade is available.) The information at the shipment from the plant is described as a reference.
● The identification grade stamped on each part is the grade for the dimension measured in new condition.
This grade cannot apply to reused parts.
● For reused or repaired parts, measure the dimension accurately. Determine the grade by comparing the
measurement with the values of each selection table.
● For details of the measurement method of each part, the reuse standards and the selection method of the
selective fitting parts, refer to the text.
HOW TO SELECT PISTON
When New Cylinder Block Is Used
Check cylinder bore grade (“1”, “2”, or “3”) on rear side of cylinder
block, and select a piston of the same grade.
NOTE:
Piston is available with piston pin as a set for the service part. (Only
“0” grade piston pin is available.)
