2006 New Holland L170 w/pilot controls hydrostatic pump issue

[BennySeigel]

New to site. We have a 2006 New holland L170 skid steer, flex plate couple between engine and pump spun out. When it did it buggered shaft on pump. Its the aa20vg45dgm2/10r pump, took awhile to locate the exact shaft bearing and seal but we did. We removed the 4 bolts one the right hand rotary pump keeping assembly together sitting upside on table slid shaft out of piston assembly then proceeded to remove snap rings and seal, replaced shaft seal and bearing. Reassemble slid back into piston assembly flipped back over stand on shaft. Proceeded to reinstall assembly back into pump with the slide long in towards the pump aligned with groove. Bolted back on and reinstalled engine. Started machine and as soon as it started the left side immediately creeped forward. Shut off. Blocked machine. Started up again. With seat belt unhooked and not touching controls left wheels creep forward. Unlocked and used pilot hand controls to operate drive hoes forward and faster than right side and creeps in reverse and doesnt stop at neutral. Removed engine and assembly again looking for errors. Can anyone provide insight on this situation of whats wrong? seams like its not finding neutral.
