Valves

Fig. 61

Check valve leakages by pouring gasoline on valve

head. Gasoline must not seep past valve seat.

Valves with burnt heads, excessive scoring and

wear on stem should be replaced.

Check valve seat run out with respect to valve

stem (Fig. 61). If it exceeds specified limit replace

valve. No attempt should be made to straighten

bent valves. If valve is free from any other defects

except worn out seat, then only it can be

rematched on valve grinding machine as follows:

Clamp valve on grindingmachine jaws as close as

possible to valve head.

Adjust grinding angle on graduated scale to

achieve correct valve seat angle.

Feed valve slowly towards grinding wheel until

wheel just touches valve head.

Grind at low feed until valve seat is just clean all

around.

NOTE

After grinding, valve head thickness should not be less

than 0.85 mm.

ValveGuides

In case of valve stem sticking in valve guide bore

or Excessive clearance between them, remove

valve guide From cylinder head using drift (Part

No.2868 5890 06 05). (Fig. 62)

Check the condition of valve guide oil seals.

Check valve guide bore diameter in cylinder head

and if necessary, ream valve guide bore in cylinder

head to next over size. (Fig. 63)
