9.

Compress the valve springs using the valve lifter.
Remove the valve collets, valve spring retainers and valve
springs.

NOTE:
Before removing the valves and the valve stem seals, it is
vital to measure position “H” of one of the old seals in rela-
tion to the cylinder head using valve seal drift [KV113B0180
(Mot. 1511-01) (commercial service tool) or equivalent tool].

10. Install the push rod (A) of valve seal drift [KV113B0180 (Mot.

1511-01) (commercial service tool) or equivalent tool] on the
valve stem seal. 
NOTE:
The inner diameter of the push rod must be identical to that
of the valve. In addition, the bottom of the push rod must
come into contact with the metal upper section of the valve
stem seal.

11. Install the guide tube (B) over the push rod until the guide tube

comes into contact with the cylinder head, locking the push rod
with the knurled wheel. 

12. Remove the guide tube assembly plus push rod, being careful

not to loosen the knurled wheel.

13. Remove the valves and valve guide seals using the valve seal

remover [KV113B0090 (Mot. 1335) (commercial service tool) or
equivalent tool].

ASSEMBLY

1.

Install new valves and grind them gently into their respective
seats. Clean all the parts thoroughly, mark them for identification
purposes, then carry out the refitting operation.
Lubricate the inside of the valve guide.
• It is imperative to fit the valve stem seals using valve seal drift

[KV113B0180 (Mot. 1511-01) (commercial service tool) or
equivalent tool].

NOTE:
Do not lubricate the valve stem seals before fitting them.

2.

Place the valve in the cylinder head.

3.

Place the barrel of valve seal drift [KV113B0180 (Mot. 1511-01)
(commercial service tool) or equivalent tool] over the valve stem
(the inner diameter of the barrel must be identical to the diame-
ter of the valve stem).

4.

Keep the valve pressed against its seat.

5.

Place the valve stem seal (not lubricated) over the tool barrel.

spring compressor.

11. Install the valve collets using tweezers.

12. Install in the reverse order of removal after this step.

Cleaning

INFOID:0000000010282102

• It is very important not to scratch the gasket faces of any aluminum components.
• Use suitable tool to dissolve any part of the seal which remains stuck to the metal surface.
• Apply the dissolving product to the part to be cleaned, wait approximately 10 minutes, then remove it using a

wooden spatula.

• Wear gloves while carrying out this operation.
• Do not allow this dissolving product to drip on to the paintwork.
• Great care should be taken when performing this operation, to prevent foreign objects from entering

the pipes taking oil under pressure to the camshafts (pipes in both the cylinder head and its cover)
and the oil return pipes.

INSPECTION AFTER REMOVAL

Cylinder Head Distortion

NOTE:
When performing this inspection, cylinder block distortion should be also checked. Refer to 

EM-356,

"Cylinder Block"

.

1.

Wipe off engine oil and remove water scale (like deposit), gasket, sealant, carbon, etc. with a scraper.

CAUTION:

Use utmost care not to allow gasket debris to enter passages for engine oil or water.

2.

At each of several locations on bottom surface of cylinder head, measure the distortion in six directions
using straightedge and feeler gauge.

• If it exceeds the limit, replace cylinder head.

Cylinder Head Height

Measure the height of cylinder head (H).

Valve protrusion

Check the valve protrusion using dial gauge stand set [KV113B0040
(Mot.251-01) (commercial service tool) or equivalent tool] and dial
gauge stand set [KV113B0050 (Mot.252-01) (commercial service
tool) or equivalent tool] as shown.
