Komatsu d31e-18 hydraulic problem

Jwbell ยท 2016-07-24 22:01

Komatsu d31e-18 blade leaks down slowly. Blade also leaks back when pushing at an angle or side to side. Dozer was just bought, has small fluid leak around spool valves under the levers. Would this cause the problem since blade leaks back in all 3 directions? Or where should I look first? Thanks.
