1D-186 Engine Mechanical: For F9Q Engine

4) Install bearing cap referring to connecting rod and

bearing cap referring to Step 9) of “Installation” under
“Piston, Piston Ring and Connecting Rod Removal
and Installation: For F9Q Engine”.

5) Remove cap, and using a scale (1) on gauging

plastic envelope (2), measure gauging plastic (2)
width at the widest point (clearance).
If measured clearance is out of specification, use a
new connecting rod bearing.
After install new bearing, recheck clearance.

Connecting rod bearing clearance
0.027 – 0.086 mm (0.00107 – 0.00338 in.)

6) If clearance can not be brought to its specification

even by using a new connecting rod bearing and/or
replace crankshaft.

Piston Protrusion

1) Install piston and connecting rod assembly to

cylinder block referring to Step 1) through 9) of
“Install” under “Piston, Piston Ring and Connecting
Rod Removal and Installation: For F9Q Engine”.

2) Using special tool and dial gauge, measure piston

protrusion at specified position (2) as shown in figure
when piston (1) reaches top dead center. Repeat this
procedure with each piston.If measured protrusion is
out of specification, proceed to next step.

Piston protrusion
“a”: 0.50 – 0.62 mm (0.0197 – 0.0244 in.)

3) Check connecting rod length referring to

“Connecting Rod and Related Parts Specification
(for Reference)” under “Cylinders, Pistons and
Piston Rings Inspection: For F9Q Engine”.If
connecting rod is normal, proceed to next step.

4) Replace piston (1) as follows in order to adjust piston

protrusion to specified value.
a) Remove piston, and measure the following

specification.
• Piston pin hole diameter “b”
• Distance “c” between top of piston and top of

piston pin hole

b) Obtain distance “d” between top of piston and

center of piston pin hole by formula below.
“d” = “b” / 2 + “c”

c) Using piston protrusion “a” measured at Step 2),

obtain adjusting distance “e” by formula below.
“e” = “d” + 0.56 mm (0.0220 in.) – “a”
Example:
When distance “d” of removed piston is 47.026
mm (1.85142 in.), and measured piston
protrusion “a” is 0.45 mm (0.0177 in.)
Calculated adjusting distance “e” = 47.026 mm
(1.85142 in.) + 0.56 mm (0.0220 in.) – 0.45 mm
(0.0177 in.) = 47.136 mm (1.85575 in.)

d) Select new piston so that distance “e” is within

range of distance “d” of new piston.

NOTE
Piston class (1) is marked on piston top as
shown in figure.

e) Replace piston with selected piston.
f) Check piston protrusion, again.

Removal

1) Remove piston and connecting rod referring to

“Piston, Piston Ring and Connecting Rod Removal
and Installation: For F9Q Engine”.

2) Remove heat exchanger referring to “Heat

Exchanger Removal and Installation: For F9Q
Engine in Section 1E”, if necessary.

3) Loosen main bearing cap bolts in numerical order as

indicated in figure, and remove them.

4) Remove main bearing cap No.1 using special tool as

follows.

Special tool
(A): 09917–56510

a) Install special tool to main bearing cap No.1 (1).
b) Pull out main bearing cap No.1 from cylinder

block by tightening bolt (2) of special tool.

Installation

NOTE

• Use new bearing cap bolts. They are

deformed after tightening once because
they are plastic deformation tightening
bolts.

• All parts to be installed must be perfectly

clean.

• Be sure to oil crankshaft journals, main

bearings and thrust bearings.

• Main bearings and bearing caps are in

combination sets.
Do not disturb such combination and make
sure that each part goes back to where it
came from, when installing.
