Installation 

  1.  Install piston with con-rod by inserting with engine oil. 

  2.  Coat piston rings with engine oil and compress with 

piston ring compressor. 

 

Important! 

Installation position: 

Arrow / notch on piston head on timing side of engine 

Beads on con-rod on clutch side 

 

 

 
 

 

 

Torque-Angle Method 

Piston to cylinder block. 

Con-rod bearing cap to con-rod-35N

⋅m (3.5 kgf⋅m) +45° to 60°

 

Important! 

Use new bolts. 

 

 

Installation 

  1.  Install oil pan and cylinder head according to the 

corresponding operations. 

  2.  Install sealing Gasket or replace if damaged. 

  3.  Install camshaft housing to cylinder head. 

  4.  Install cylinder head according to the corresponding 

operation. 

 

 

 

 

 

Con-Rod 

Removal 

  1.  Remove piston with con-rod according to the 

corresponding operation. 

  2.  Disassemble con-rod piston assembly by pressing out 

piston pin, using 5-8840-0468-0. 

 

 

Installation 

  1.  Slide guide drift (5-8840-0468-0) in horizontal position 

through piston and con-rod as far as side plate stops. 

  2.  Tighten bolts evenly so that the piston rests flush on the 

rear plate. 

  3.  Remove centre piece from guide drift and insert piston 

bolts (lubricated) into guide drift.

  4.  Heat a new con-rod to 280

°C in the oil bath. 

  5.  Install the con-rod to the piston and insert the piston pin.

 

 

Important! 

Since the con-rods have no weight balancing studs, re-working 

is not possible. 

Exchange con-rods in sets only. 

Installation position, beads on con-rod point to the flattening on 

the piston pin eye. 

Firmly seated piston pin cannot be pushed in. Carry out 

installation quickly. 

 

 

 

 
 
 
 

 

Piston Rings 

Removal 

  1.  Remove piston with con-rod according to the 

corresponding operation. 

  2.  Remove piston rings using commercially available ring 

installer or piston ring clamp pliers. 

 

Clean 

Piston ring grooves - ground piece of old piston ring
