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.
