Example) Measured value D
= 37.100 mm
Measured value D2 = 37.010 mm
Overlap value ‘U’
= 0.090 mm
If overlap value ‘U’ is out of standard,
machine the basic bore for the valve
seat ring.
8. Turn over the cylinder head.
9. Remove the tensioning head (4) and valve seat
ring (2) with drift (14 mm) and removal tool.
10. Clean the basic bore of valve seat ring.
11. Measure the basic bore diameter (D2) and outer
diameter (D) of the new valve seat ring (standard
size).
12. Calculate the overlap value ‘U’ (D - D2).
- Measure machined basic bore and outer
diameter ‘D’ of valve seat ring (repair size).
- Measure the overlap ‘U’
13. Clamp the cylinder head with clamping device.
14. Machining basic bore for valve seat ring (repair
size).
Notice: Maintain minimum value of ‘B’.
- Machine the basic bore.

Overlap U
= 0.120 mm
The basic diameter D2 must be
machined by 0.020 mm in order to get
the required overlap value.
