I replaced the bronze filter, not the issue evidently. The old one looked to be in good shape. Any other ideas before I go to the stealer ship? Any chance it is the bypass valve or am I way off base?

I was told all the filters were replaced about 10 hours ago, and they do look new. I'll check them tho. It's not just trying to spin, it's turning at all, makes a whining noise and just won't go. Goes forwards and backwards with no problems.

Well I got a new filter in it. Didn't fix my problem tho. Any other ideas? Bypass valve maybe? More serious issues? Thanks Mike

Ahh. Makes sense. Thanks to you both. I'll give it a shot.

That was one of the things I was considering but wouldn't that affect the drive in all directions? That and the by-pass valve. Like I said it will go good in forward and reverse but it wont with one side going forward and one side going reverse. Could it be the replenishing valve?s? But again...

I have a 1980ish bobcat 630. It is new to me and I am a skidsteer noob. It runs great and functions fine for about 15 minutes or so. Once good and warm it starts to hesitate to turn and eventually won't turn at all. Makes a loud whining noise when trying. I have the manual and it looks like it...

Hi new 630 bobcat owner here. I see on the maintenance chart inside the motor door that my (1980ish) 630 bobcat is supposed to use 10w-30 or 40 oil in the hydraulics and it specifically says NOT to use hydraulic fluids. Can anyone confirm this is right? The bobcat dealer I spoke with said to...

Id love a copy of the 630 manual too please. [email protected] Thanks
