Scored accumulator bores create loss of clutch pressure or cross leaks.
The accumulator bore sleeves are made from wear-resistant aluminum and the length of the piston-to-pin contact area has been increased to reduce piston cocking and increase sealing surface area.
The accumulator bores on AXOD & E, AX4S channel castings can become scored, which creates loss of clutch pressure or cross leaks. The continuous oscillation of the piston within the bore causes excessive wear. Also a broken accumulator spring can get caught between the piston and the bore causing a deep groove in the casting wall. You can resolve these problems by installing these Sonnax AXOD & E, AX4S accumulator bore sleeve kits.
