After finding that Merc dealer wanted $1430 for new pump (part only, Not installed) I found & joined this site looking for a cheaper alternative. I did find cheaper brand new pump $690 + GST from accessparts.com.au
I decided to take the pump apart. Not so hard. Using vice grip pliers I bent the tabs out only a little bit each, The casing pulls straight out & off, Could smell that electrical "burnt" smell. Also could see that 1 armature winding had burnt. I took the armature to Kenshaw electric motors at Cardiff. They sent it away to somewhere in Brisbane & had it rewound. $180 + GST later & I had it back. Put motor back together, bench tested it & it worked. Put pump back in van. Replaced blown 40A fuse. Started motor, selected gear, Great, it moved. Done a few laps of the block, no probs. Changed hydraulic oil Using Penrite LDVS. Took it for a 20km drive changing from 5th to to 6th to 5th to 6th etc alot so pump would be working. No probs. Went to Syd & back this week , No probs. Fixed & happy
Reason pump had burnt out was the Bushing / bearing had seized, I cleaned up shaft & reoiled bushing. Hope this story helps someone else to sort out their problem cheaply.
Its not so hard to take pump out. Just need 8mm & 10mm torx socket , Small torx driver bit set , 10mm open end spanner (wrench for you Americans). Leave pipework connected to pump & undo pipe at other end. Bottom pipe just pulls off fitting
