8. Turn over the cylinder head.
9. Remove the tensioning head (4) and valve seat ring
(2) with drift (14mm) and removal tool.
10. Clean the basic bore of valve seat ring.
11. Measure the basic bore diameter (D2) and outer di-
ameter (D) of the new valve seat ring (standard
size).
12. Calculate the overlap value ’U’ (D -- D2).
Overlap Value ’U’
0.068 -- 0.100 mm
Example) Measured value D = 37.100mm
Measured value D2 = 37.010mm
——————————————
Overlap value ’U’ = 0.090mm
If overlap value ’U’ is out of standard, machine the
basic bore for the valve seat ring.
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.

-- Measure machined basic bore and outer diame-
ter ’D’ of valve seat ring (repair size).
-- Measure the overlap ’U’.
Overlap ’U’ (D--D2)
0.068 -- 0.100 mm
Example) Measured value D = 37.600mm
Measured value D2 = 37.480mm
——————————————
Overlap value ’U’ = 0.120mm
The basic diameter D2 must be machined by
0.020mm in order to get the required overlap value.

15. Hang the cylinder head (1) to the lifting device and
heat in a water tank to approx. 80_C.
16. Cool down new valve seat ring (2) into the cooling
box with liquidnitrogen.
Notice
Do not touch the cooled valve seat rings with hand.

17. Drive in new valve seat ring (2) with a proper wood-
en drift.
18. Install the valve guide (3) with a proper drift and as-
sembling tool.
Notice
The valve guide must be driven in from the cylinder
head cover.
Drift (Intake) 8mm
Drift (Exhaust) 9mm
19. Machine the valve seats.
