Removal Procedure
1. Measure dimension ’A’.
Limit142.5 mm
2. Clamp the cylinder head with clamping device.
3. Cut groove into the valve seat ring so that dimension
’C’ is approx. 2mm and dimension ’E’ is approx.
6mm.
4. Remove the cylinder head from the clamping device
and place it onto wooden blocks.
5. Remove the valve guide (3).
Drift (Intake) 8mm
Drift (Exhaust) 9mm
6. Insert the tensioning head (4) and extracted wedges
(arrow) by turning the bolt (5).
Notice
Carefully tighten the bolt (5) otherwise the valve
seat ring in the cylinder headwill be excessively ten-
sioned.
7. Lock the bolt (5) with nut (6).

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’.

-- 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.

Checking and Machining
1. Clean the valves and do visual check.
Valves with wobbled valve disc, with worn or scored
valve stem should be replaced.
2. Measure valve disc height ’h’.

3. Machine the valve.
Notice
Pay attention to setting angle ’a’.
4. Measure radial runout between valve stem and
valve seat.

5. Clean the vales, valve seats and valve guides.
6. Coat the valve stem with oil and insert it into valve
guide.
7. Insert the valves (1) into the valve guides according
to marking.
8. Measure amount by which the valve arrears ’a’.
Arrears ’a’0.1 -- 0.7 mm
Notice
If out of standard, replace the valve seat ring.
9. Measure camshaft cam basic diameter (w).
Diameter ’w’38±0.2 mm
or 37.6±0.2 mm
10. Measure distance ’z’ (cylinder head cover parting
surface -- valve stem).

OM600 ENGINE MECHANICAL 1B3 -- 131
D AEW OO M Y_2000
11. The distance ’x’ (camshaft basic bore -- valve stem).
’x’ = ’z’ -- ’y’.
Determine the valve to use according to this mea-
surement (See ’matching valves’)
Example) Measured value ’w’= 38.2 mm
Measured value ’z’ = 36.5 mm
—————————————
Value’y’ =15.5mm
’x’ = 36.5 -- 15.5 = 21.0mm
In this case according to ’Matching valves’ table, the
installed valve may be used.
