2.Pin Insertion: Align piston pin with piston bores and connecting rod small end
3.Press Fitting: Using proper mandrel, press pin into position with steady pressure (maximum 5-10 kN)
4.Verification: Ensure pin rotates freely in connecting rod without binding
5.Clearance Check: Verify pin-to-piston clearance (0.002-0.005 mm) and pin-to-rod clearance (0.015-0.035 mm)
Critical Warning:
Never hammer pin into position - use proper press tooling
Always replace piston pins in complete sets per cylinder
Verify pin retention method (circlips/set screws) are properly installed
Check pin end float (0.5-1.0 mm) after installation
Post-installation:
Système d'huile de premier ordre avant le démarrage initial
Follow engine break-in procedure recommended by manufacturer
