Insert inlet and exhaust valve seat inserts before pressure testing.
1. Undercool valve seat inserts in liquid nitrogen to -195°C.2. Insert inlet and exhaust valve seat inserts.3. After fixing the valve seat inserts press them for a short moment
on the nut by means of the device 2500.7-92.22.00-02 andtighten them with the torque stated, see below.
4. Checking of the contact face Y2 between inlet valve seat insertand cylinder head.No clearance admissible !
5. Checking of clearance Y1 between exhaust valve seat insert andcylinder head.Admissible clearance 0,4+0,5mm
Pressure test : cooling water chambers 10 bar maintainedover a period of 8 min.
sequence of operations for the insertion of the valve seat inserts
Tighten nut with 50 Nm(pretension 29 kN).Treat thread and surfaceslightly with Molycote paste G.
