[QUOTE="Tazza, post: 13423, member: 82"] Ok, more piccies. This is the pump before, still all greasy... [IMG]http://users.tpg.com.au/tazza_/751/hydro/152_5246.jpg[/IMG] Here is the problem, note the charge line was burnt up in the fire and this is carbon from the burnt rubber. This has gone throughout the entire system. Its even in the drive motors! [IMG]http://users.tpg.com.au/tazza_/751/hydro/152_5249.jpg[/IMG] Swash plate is on the left still attached to the valve, part of the rotating group is on the right. [IMG]http://users.tpg.com.au/tazza_/751/hydro/152_5254.jpg[/IMG] Swash plate again, note the black crud, this is carbon from that rotten hose! [IMG]http://users.tpg.com.au/tazza_/751/hydro/152_5257.jpg[/IMG] Pistons from the rotating group, plus the bits that allow it all to pivot. [IMG]http://users.tpg.com.au/tazza_/751/hydro/152_5258.jpg[/IMG] Rotating group all ready to install, just needs those 3 pins and that cupped *thing* seen in the photo above. This is the hardest piece of all to install as it moves around on you. Using thick grease here sure does help.
