Such hydraulic type stays can be either for both-side or one-side installation:
• Hydraulic type stays for one-side installation have two oil chambers (one on
each side of the piston) and provide in this regard a ‘damping effect’ in both
directions.
• Hydraulic type stays for both-side installation have an oil chamber on one
side of the piston and an air chamber on the other side. The air chamber
provides little to no damping effect.
The two general arrangements for both stay types are shown below in Figure 6-7
and Figure 6-8.

Figure 6-8 General arrangement of hydraulic type stays for both-side installation
NOTE
The selected hydraulic type stays must be suitable for one-side instal-
lation on the engine. The suitability of one-side installation must be con-
firmed by the hydraulic type stay supplier.
