Hydraulic oil foams when lowering bucket

Post by Bill Walter » Thu Mar 02, 2006 7:35 am

What would cause the hydraulic oil to foam and overflow the reservoir when I lower the bucket on my 831 loader. Any help on this would be appreciated

Sounds like it's sucking in air some place and aerating the hydraulic fluid badly. See any leaks in the hydraulic system anywhere at all?
