I have a 616 in which I installed a hydrostat in this weekend. It now won't go up inclines and it did before. I put a new hydrostat belt on it a few months ago and I struggled getting it on. This morning I finished up the hydrostat install and had no problem putting the belt back on it. Now it squeals going up inclines. I'm thinking it could be the belt install? Any suggestions is greatly appreciated.
have you purged them properly ?
Engine running as low as possible , wheels off the ground bypasses open the do slow forward & reverse movements with the lap bars .
Might take several hours to get all the air our .

The levers, rods , nuts whatever you move when you want to push the mower
That diverts the oil from the pump back to the sump bypassing the motors
To remove the air there must be nothing to put a load on the motors so they can spin freely under the influence of air alone .
If there is a load on the wheels then all that happens is the air in the cylinders compresses a bit then expands so it never goes away so the oil never replaces it
There are no seals inside a hydro drive so the whole shooting match relies on the viscious friction of the oil.

So the bypasses are open when there's no load on the wheels but the wheels are turning because they're off the ground? Sorry I'm a little confused.
Yes exactly right
Wheels off the ground and as you work the lap bars from full forward to full reverse the wheels will become more responsive as the air is expelled till eventually you can not stop them by dragging your foot on the wheels
The engine must be running very slow to avoid foaming the oil

Awesome! Thank you so much. Since this will apparently take awhile, I'll do it this weekend. Thanks again, I'll let you know how it goes.
Dust is the enemy of hydros , so not unless you are doing this is a very clean garage & the underside of the mower is spotless
You are not really changing the volume all you are doing is getting the oil on the bottom & the air on the top

Ok good. Like I said, since this will be time consuming I'm going to do this over the coming weekend. How often should I move the levers back and forth slowly?

Good morning, I didn't get a chance to work on my mower this past weekend but I do have another question for you. Do you have anything that explains how to adjust the levers? I know it's in the linkage but I can't seem to get them right.
