4. Heat cylinder head to 110 to 130ÉC (230 to 266ÉF) and press
service valve guide onto cylinder head.
Projection ªLº:
10.4 - 10.6 mm (0.409 - 0.417 in)
5. Ream valve guide.
Finished size:
6.000 - 6.018 mm (0.2362 - 0.2369 in)
VALVE SEATS
+Before starting this check, confirm that the dimensions of
valve guides and valves are as specified.
+Apply red lead primer on contacting surfaces of valve seat
and of valve face to examine the conditions of contacting
surfaces.
+Check that the paint on contacting surfaces is continuous
along the entire circumference.
+If there are abnormal indications, grind the valve and check
the contact again. If abnormal indications still persist, replace
valve seat.
REPLACING VALVE SEAT FOR SERVICE PARTS
1. Bore out old seat until it collapses. Boring should not con-
tinue beyond the bottom face of the seat recess in cylinder
head. Set the machine depth stop to ensure this.
2. Ream cylinder head recess for service valve seat.
Oversize [0.5 mm (0.020 in)]:
Intake 30.500 - 30.516 mm (1.2008 - 1.2014 in)
Exhaust 29.500 - 29.516 mm (1.1614 - 1.1620 in)
Be sure to ream in circles concentric to the valve guide
center.
This will enable valve seat to fit correctly.

3. Heat cylinder head to 110 to 120ÉC (230 to 248ÉF) by soak-
ing in heated oil.
4. Sufficiently cool valve seat with dry ice. Force fit valve seat
into cylinder head.
WARNING:
Do not touch cold valve seat with your bare hands.
5. Cut or grind valve seat using suitable tool to the specified
dimensions as shown in SDS (EM-3092).
CAUTION:
Use the valve seat cutter properly. Securely gripping the
cutter handle with both hands, press the cutter down onto
the entire circumference of the contacting surface and fin-
ish cutting at one time. Improper pressing of the cutter or
cutting in several steps may result in staged surface on the
valve seat.
6. After cutting, lap valve seat with abrasive compound.
7. Check valve seating condition. Refer to EM-3053, ªValve
Seatsº.
8. Use a depth gauge to measure the distance between the
mounting surface of the cylinder head spring seat and the
valve stem end. If the distance is shorter than specified,
repeat step 5 above to adjust it. If it is longer, replace the
valve seat with a new one.
Valve seat resurface limit ªLº:
Intake 36.53 - 36.98 mm (1.4382 - 1.4559 in)
Exhaust 36.53 - 37.01 mm (1.4382 - 1.4571 in)

VALVE DIMENSIONS
Check dimensions of each valve. For dimensions, refer to SDS
(EM-3089).
When valve head has been worn down to 0.5 mm (0.020 in) in
margin thickness, replace valve.
Grinding allowance for valve stem tip is 0.2 mm (0.008 in) or
less.
VALVE SPRING
Squareness
1. Measure dimension ªSº.
Out-of-square ªSº:
Limit 1.9 mm (0.075 in)
2. If it exceeds the limit, replace spring.
Pressure
Check valve spring pressure at specified spring height.
Standard:
Free height 43.7 mm (1.720 in)
Installation height 32.82 mm (1.2921 in)
Installation load 184 - 208 N (18.77 - 21.22 kg, 41.4
- 46.8 lb)
Height during valve open 24.82 mm (0.9772 in)
Load with valve open 320 - 360 N (32.65 - 36.73 kg,
71.9 - 80.9 lb)
If it exceeds the standard, replace spring.
VALVE LIFTER
1. Check contact and sliding surfaces for wear or scratches.
2. Check diameter of valve lifter and valve lifter guide bore.
Valve lifter outer diameter:
29.960 - 29.975 mm (1.1795 - 1.1801 in)
