Spring - Stihl 064 Service Manual

STIHL 064, 066
Pressing home rewind spring with press
disk 5910 893 5100
- The replacement spring is supplied with
spring housing ready for installation. It
should be lubricated with a few drops of
STIHL special lubricant (see 12.2) before
installation.
- Position the replacement spring with
spring housing (bottom plate must face
up) in the fan housing. Make sure the
outer spring loop engages the recess in
the fan housing.
Important: The pads on the spring
housing mean that a certain resistance has
to be overcome when in stalling the spring.
Apply pressure evenly over the whole
surface of the spring housing to prevent it
being twisted.
Important: If the rewind spring pops out
and uncoils during installation, it must be
refitted in the spring housing as follows:
Top:
Position of outer spring loop
a = 25 mm (1")
Bottom:
Fitting rewind spring with aid of wooden
assembly block 1108 893 4800
- Position the outer spring loop
about 25 mm (1") from the edge
of the spring housing.
- Refit the rewind spring in the
spring housing in the counter-
clockwise direction, starting from
the outside and working inwards.
Note: The wooden assembly
block can be placed over the
spring housing to simplify refitting.
