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.

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.
