Installing

– Before installation, coat the
knurled area of the new pin with
Loctite 243, b 13.
– Position the new pin in the bore
so that the knurling on the pin
meshes with the existing knurling
in the bore. Turn pin back and
forth as necessary.
– Carefully tap home the pin
squarely from the outside
inwards, in direction of cylinder.
