REASSEMBLING THE CYLINDER BLOCK 

(Refer to component part illustration for disassembly and 
reassembly) 

ADVICE: 
* Carefully clean all parts to reinstall. 
* Before reassembling parts, coat all sliding and rotating 
surfaces with fresh engine oil. 
* Replace any linings or oil seals with new parts

. 

 

1.  REINSTALL THE CYLINDER BLOCK OIL JET 

 

 

 
 
 
 

2.  REINSTALL THE INJECTORS AND CHECK 

VALVES 
 

a.  Make the needle of the injector coincide with the cylinder 

block needle hole. 
 

b.  Reinstall each injector with its check valve. Reinstall the 

four injectors and check valves. 
 

Recommended tightening torque:25 N.m (260 kgf.cm) 

 

 
 

3.  REINSTALL CRANKSHAFT BEARING SHELL 

BEARINGS 
 

a.  Make the rib in the shell bearing coincide with the 

corresponding groove in the cylinder block and reinstall 
the five top shell bearings. 
 
 
 
 
 
 

b.  Make the rib in the shell bearing coincide with the 

corresponding groove in the bearing cap, then reinstall 
the five lower shell bearings
