Brake Spring Anchor Pin; Hand Guard Pivot Pin - Stihl 088 Owner's Manual

Brake Spring Anchor Pin

- Remove the cylinder - see 4.5.1.
- Remove the chain brake – see
3.3.1.
• Use a suitable punch to drive the
anchor pin out of the crankcase
in the direction of the arrow.
Important! Do not drive out the
pin in the other direction as this
would damage the annular bead
which was formed in the crankcase
bore when the pin was
originally installed.
In such a case neither the new
anchor pin nor the brake spring
would locate properly. Furthermore,
the crankcase could be damaged in
this way and possibly impair correct
operation of the chain brake.

- If the brake spring anchor pin has
been removed, coat the knur-
led area of the new pin with Locti-
te, see 11.2, before installation.
- Position the new pin in the bore
so that the knurling on the pin
meshes with the existing knurling
in the bore.

Carefully tap home the pin
squarely to obtain dimension
"a" = 4.3 - 4.7 mm (11/64").

at exact right angle.
