4. Check crankshaft end play. 

Using a dial indicator, measure the thrust clearance while prying the crankshaft back and forth with a 
screwdriver. 

Standard end play 

0.10-0.28 mm (0.0039-0.0110 in.)

5. Inspect main journals and crank pins 

Using a micrometer, measure the diameter of each main journal and crank p in. 

Main journal diameter: 68.942-68.960 mm (2.7142-2.7149 in.) 

Crank pin diameter: 54.954-54.972 mm (2.1635-2.1642 in.)

CONNECTING RODS 

1. When reinstalling, make sure that cylinder numbers put on the connecting rod and cap at disassembly 

match. When a new connecting rod is installed, make sure that the notches for holding the bearing in 
place are on the same side.  

2. Replace the connecting rod if it is damaged on the thrust faces at either end. Also if step wear or a 

severely rough surface of the inside diameter of the small end is apparent, the rod must be replaced as 
well.  

3. Using a connecting rod aligning tool, check the rod for bend and twist. If the measured value is close to 

the repair limit, correct the rod by a press. Any connecting rod that has been severely bent or distorted 
should be replaced.  

Allowable bend of connecting rod : 

0.05 mm/100 mm (0.0020 in./3.94 in.) or less

Allowable twist of connecting rod : 

0.1 mm/100 mm (0.0039 in./3.94 in.) or less 

CYLINDER BLOCK 

1. Remove gasket material. 

Using a gasket scraper, remove all the gasket material from the top surface of the cylinder block. 

2. Clean cylinder block 

Using a soft brush and solvent, thoroughly clean the cylinder block. 

3. Inspect top surface of cylinder block for flatness. 

Using a precision straight edge and feeler gauge, measure the surface contacting the cylinder head gasket 
for warpage. 

Flatness of cylinder block gasket surface 

Standard: Less than 0.05 mm (0.0020 in.), Less than 0.02 mm (0.0008 in.) /150 x 150

4. Inspect cylinder bore diameter 

Visually check the cylinder for vertical scratches. 

If deep scratches are present, replace the cylinder block.
