I am having some confusion about purchasing the correct hydraulic orbital motor for my Case 190.  I have attached two photos.  The motor that is on my case 190 which has hydraulic breaks.  The break has 4 bolts that seam to attach onto the motor.  The recommended replacement motor by Char-Lynn, 101-1072-009 appears to have no bolts to attach the hydraulic break.  THE PROBLEM IS... the replacement motor does not have the 4 bolts for the break.  It that the correct motor or is there another motor.

Are you sure your drive motor bad? If so pull your brake assembly off measure the flat on motor contact Char-Linn see if the will give dimensions of flat. If the same any good machine shop can drill and tap the holes for you. If you have a hydraulic shop close they might be able to rebuild your motor.

Just to recap the issues.  The Hyd. pump was replaced about a year ago with fresh rotella 15w40.  The oil reservoir is filled to proper amount.  The tractor has more power in reverse than forward.  When going up a hill in forward the tractor stops moving without the motor bogging much.  The control valve linkage travels fully in and out.  All bolts on the hyd. motor are tight.  Help, Help, before I spend $340 on a new hyd. motor.

 

FYI the model pump installed- Concentric/Haldex High Performance Gear Pump — .61 Cu. In., Model# WP09A1B100L03BA102N.

I'm no hydraulic man but lose of power in a motor usually oil by passing the geroler and you would think it be both forward and reverse that would lose power. I'd pull the TCV spool look at o rings see if that's where the oil is by passing. Make sure spool is free of scratches and is tight fit.
