[QUOTE="roblarss, post: 88142, member: 9491"] I just did a rebuild on mine after the charge pump failed. I also rebuilt both of the drive pump sections. The pump will come out as one unit and then it can be taken apart into the different pump sections fairly easily. My drive pumps had wear marks on the valve plates. Now I have a huge difference in pushing power. I got the manuals from the danfoss site. http://files.danfoss.com/documents/11077090.pdf or search for danfoss m91 manual in google for their other manuals Full gasket set was about $200 valve plates about $150 each. Cant hurt to take apart and look. I found it fairly easy and I have never tried to repair any type of hydraulic pump. Could be something as simple as linkages to the swash plate is apart. Some parts can be removed to check while the unit is still installed. I bought parts directly from our local danfoss dealer. [/QUOTE]
