Is it possible for a 190xt to move forwards and backwards under its own power if the hydraulic pump is completely shot and not working? mine is moving backwards and forwards but I don't have any other hydraulic functions Is there a diagram of how to line up the flow divider on the back of the series 3 pump? Thanks

Which pump do you have? At what rpm is the problem at?

There is a 2 section with a priority flow divider and a 3 section which supplies steering and power pressure from one section.

If you have pressure to the power director you should have steering.

On the flow divider pump at very low rpm, there may not be enough flow for the hydraulics.

Have you tried the position control to see if it will lift?

You need a service manual to troubleshoot the problem.

the only manual I have is a reproduction that says it covers the series 3 but it only shows 1 style of pump like my 67 190XT has. My series 3 has the early 200 style pump I took the pump off and apart and found the main shaft gear spins loosely on the shaft and is all discolored I assume it got pretty hot
