Cylinder head
103
The Cylinder head of the MTD engine can be removed
without removing the engine from the application.
To remove the cylinder head:
NOTE: If possible, It is recommended that the machine be
positioned on the bench so that the cylinder head
is vertical for removal. See Figure 9.1.
NOTE: This position provides easy access to most service
points, yet prevents undue oil spillage.
NOTE: Do not store the engine in this position for a long
period of time. The oil will seep into the breather
chamber.
NOTE: It is not absolutely essential to remove the fan
shroud, but taking the engine cover off, if
equipped, will ease access to some components.
1. Disconnect and ground the spark plug high tension
lead.
2. Remove the spark plug using a 13/16” or 21mm
wrench. See Figure 9.2.
3. Rotate the crankshaft until it is at TDC of the com-
pression stroke by following the steps described in
the valve lash section of Chapter 1: Introduction.
4. Remove the four screws securing the valve cover
using a 10mm wrench. See Figure 9.2.
