of the rods and guides valve
(Tab. 8.10)
.
If the diameters don't correspond to the values indicated, replace
the valves or guides.
The
MAX
allowed value of wear for
D and E
is 0.10 mm.
Observe values G from surface F when assembling guides H
(Tab. 8.10) .
Important
ï‚·
Carry out the measurements in different points to detect
any ovalisation and/or concentrated wear.
