Just got this into shop, blade and swing weak, they work off same section of pump with common pressure relief. Can only build 2045 psi. Won't build enough pressure to open relief. Believe pump to be worn. I would like to know spec to verify. Thanks for any help,
Yanmar vio40 Did you ever fix or replace pump on that excavator? I am in need of one for mine, could you give me a good lead on a rebuilder or manufacturer. matt
