S630D hydraulic HELP!!!

[LarryP]

OK I changed the oil and cleaned the filter, at the bottom of the reservoir, and the front bucket lift is very week. Is there anything else that I can do before I have to work on the hydraulic pump. If this is my only option is there rebuild kits out there or do I have to buy a new or rebuilt pump?

Thanks for the help

Is is "weak" or "slow"...? ("bucket" slow could be loader control assy)

Does your 3-pt work ok? (if so then pump is good, unless you have an aux. pump for loader)

I just purchased some Satoh manuals... I believe I have something on the Bull model... and the S630 should be the same... I'll follow-up later for ya...

Page 1 of Hydraulic Troubleshooting for S630...

(appears to be the same Hyd. pump as my S650, but engine mounted instead... very expensive OEM ~~ $1200...?, replacement elsewhere about $350... not something to guess on... I've never seen a rebuilt kit avail...{maybe 20 years ago though} /forums/images/graemlins/blush.gif)

(I'll u/l other 2 pages later...)
