Öhlins Shock Absorbers Type CCJ for Short Track Racing Owners Manual

Introduction

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 thatyou have decided to fit with Öhlins suspension.

Before installation

Öhlins Racing AB can not be held responsible for any damage whatsoever to suspension or 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.

Öhlins Shock Absorbers Type CCJ Design

The CCJ shock absorber is of a mono tube pressurized model, using a piston with shims to control the damping (fig. 1). The CCJ shock absorber can be fitted with an internal dividing piston (fig. 2) or an external reservoir with a dividing piston (fig. 3) , keeping the gas separated from the shock absorber fluid. This prevents the risk of cavitation that can wear out internal components and cause inconsistent damping. It also eliminates aeration of the damping fluid, which also causes inconsistent damping. It improves the cooling, since the fluid is in direct contact with the outer tubing. It gives more consistent damping, regardless of the shock absorber’s working temperature, and it makes the shock absorber last longer.

The internal pressure is balanced to cope with temperature build up and to prevent any chance of cavitaion, yet reducing the fluid compressibility and the friction from the pistons and the shaft seal.

The CCJ shock absorber can be delivered in three different lengths to fit into different competition classes and is designed to be used as a coil over suspension unit when fitted with spring seats and adjusters. The new Öhlins shock absorbers are built to perform and endure. They are easy to set up and to sort out. Thanks to the design of the main body they are also easy to maintain and to rebuild. All Öhlins shock absorbers are built with a desire to win and with precision that ends up in quality, a quality you can see and feel.

The flow through the piston and is regulated by a rebound shim stack and a compression shim stack (fig. 4). The main piston (fig. 5), is specially developed for oval track racing. Thanks to the shape of the apertures in the piston the damping force builds up rapidly. The result is excellent short stroke/high force performance. The shim stack’s resistance to opening is decided by the quantity, thickness and diameters of the shims (fig. 6), and are carefully chosen to make each shock give optimum results.
