guide

Measure the clearance between the valve guide and valve stem.
If it exceeds the limit, replace the valve guide or valve, or both.

Standard value:

Intake 0.020 - 0.047 mm (0.0008 - 0.0018 inch)
Exhaust 0.035 - 0.062 mm (0.0014 - 0.0024 inch)

Limit:

Intake 0.10 mm (0.003 inch)
Exhaust 0.15 mm (0.005 inch)

VALVE GUIDE REPLACEMENT PROCEDURE

1.

Using a press, remove the valve guide toward the cylinder
block.

Do not install a valve guide of the same size again.

2.

Rebore the valve guide hole of the cylinder head so that it fits
the press-fitted oversize valve guide.

Valve guide hole diameters

0.05 oversize: 11.050 - 11.068 mm (0.4351 - 0.4357
inch)
0.25 oversize: 11.250 - 11.268 mm (0.4430 - 0.4436
inch)
0.50 oversize: 11.500 - 11.518 mm (0.4528 - 0.4535
inch)

Protrusion

3.

Press-fit the valve guide until it projects by the specified
amount.

Protrusion: 16.7 - 17.3 mm (0.66 - 0.68 inch)

NOTE:

When press-fitting the valve guide, work from the

cylinder head top surface.

NOTE:

Pay attention to the difference in length of the

valve guides. [Intake side: 45.5 mm (1.79 inches);
exhaust side: 52.5 mm (2.07 inches)]

NOTE:

After installing the valve guides, insert new

valves in them to check for smooth operation.

2.

Rebore the valve seat hole in the cylinder head to a selected
oversize valve seat diameter.

Intake seat ring hole diameters

0.3 oversize:
36.30 - 36.33 mm (1.4292 - 1.4301 inches)

Exhaust seat ring hole diameters

0.3 oversize:
32.30 - 32.33 mm (1.2717 - 1.2726 inches)

3.

Before fitting the valve seat, either heat the cylinder head up
to approximately 250°C (482°F) or cool the valve seat in liquid
nitrogen, to prevent the cylinder head bore from galling.

4.

Using a valve seat cutter, correct the valve seat to the
specified width and angle.
