2. Check forscratches andseizure. Ifseizure isfound, hone
it.
• Ifcylinder blockorpiston isreplaced, matchpiston grade

3. Measure pistonskirtdiameter.
Piston diameter "A":
Refer toSDS (EM-161).
Measuring point"a"(Distance fromthebottom):
Refer toSDS (EM-161).
4. Check thatpiston-to-bore clearanceiswithin specification.
Piston-to-bore clearance"B":
0.015 -0.035 mm(0.0006 -0.0014 in)
5. Determine pistonoversize according toamount ofcylinder
wear.
Oversize pistonsareavailable forservice. RefertoSDS (EM-

6. Cylinder boresizeisdetermined byadding piston-to-bore
clearance topiston diameter "A".

7. Install mainbearing capsandtighten boltstothe specified
torque. Thiswillprevent distortion ofcylinder bores.
8. Cut cylinder bores.
• When anycylinder needsboring, allother cylinders must
also bebored.
• Donot cuttoo much outofcylinder boreatatime. Cutonly

Install crankshaft andmain bearing capsandtighten bolts
to the specified torque.

• Apply newengine oiltobolt threads andseat surface.
• Prior totightening bearingcapbolts, placebearing capin
its proper position byshifting crankshaft inthe axial direc-
tion.
• Tighten bearing capbolts gradually intwo orthree stages.
Start withcenter bearing andmove outward sequentially.
• After securing bearingcapbolts, makesurecrankshaft
turns smoothly byhand.

3. Measure crankshaft endplay.

Crankshaft endplay:
Standard:
0.060 -0.180 mm(0.0024 -0.0071 in)
Limit: 0.3 mm (0.012 in)
If beyond thelimit, replace thrustbearing witha

new one.

4. Install connecting rodbearings inconnecting rodsandcon-
necting rodcaps.

• Confirm thatcorrect bearings areused. Referto
"Inspection" (EM-52).
• Install bearings sothat oilhole inconnecting rodaligns with
oil hole ofbearing.
• Apply engine oiltobolt threads andbearing surfaces.

5. Install pistons withconnecting rods.
a. Install themintocorresponding cylinderswithTool.

• Becareful nottoscratch cylinder wallbyconnecting rod.
• Arrange sothat front mark onpiston headfaces toward

angle wrench. Ifan angle wrench isnot avail-
able tighten nutsto23 to28 N'm (2.3to2.9 kg-m,
17 to21 ft-Ib).

6. Measure connecting rodside clearance.

Connecting rodside clearance:
Standard:
0.200 -0.470 mm(0.0079 -0.0185 in)
