Ohlins shock absorber ST 44 Owners Manual
All of Öhlins advanced suspension products are adepted to the brand and model. This means that length, travel springaction and damping characteristics, are tested individually just for the vehicle that you have decided to fit with Öhlins suspension.
Before installation
Öhlins Racing AB can not be held responsible for any damage whatsoever to suspensionor vehicle, or injury to persons, if the instructions for fitting and maintenance are not followed exactly. Similarly, the warranty will become null and void if the instructions are not adhered to.
Tuning the suspension
Road holding qualities
All vehicles are designed with a suspension geometry that includes wheel movemnets and angles. The changing of components can affect this and it is therefore essential that both the rear and the front ends match each other. Changing to Öhlins suspension gives optimum performance only when both the front and the rear suspension interact properly.
Everything must harmonize
Incorrect spring action can affect the road holding abilities in a negative way. This in turn can give a tendency for oversteering or understeering, which could seriously affect the road holding characteristics of the vehicle. Its important that the springs are checked for correct lenght and stiffness when Öhlins shock absorbers are mounted.
Design
The Öhlins suspensions type ST 44 is of the De Carbon type. The fluid is put under gas pressure and the gas and the fluid are kept apart by a separating piston. The gas and the separating piston are fitted in separate fluid reservoir, connected by hose or fixed direct on top of the shock absorber (piggyback). Pressurization of the fluid is made with nitrogen.
The pressurization prevents cavitation of the fluid and the shock absorbing action is therefore more even. The external fluid chambers also contribute to better cooling of the fluid, giving longer service life for both the fluid and components.
Öhlins shock absorbers have integrated temperature compensation. As the temperature increases and the fluid flows more easily the flow is controlled accordingly. The shock absorbing effect is therefore independent of the temperature. Öhlins shock absorbers provide the possibility for adjustment, making them adaptable to most vehicles, drivers and ranges of use.ST 44 models permit individual adjustment of compression damping and rebound damping, and also certain adjustment of the length of the shock absorber. The ST 44 can be equipped with high and low speed compression damping.
