I recently built a crated JM284LE with a ZL20 FEL. Everything went well - I evan gave it a drive around before putting the FEL into place and snapping it all into the quick snap fittings.
This is when the problems started!! After few minutes of running and a raise and lower of the FEL - "CRACK" the hydraulic pump split open and oil everywhere and the motor stalled /forums/images/graemlins/shocked.gif
Not being one for hydraulics /forums/images/graemlins/smirk.gif I quickly installed another new pump - "CRUNCH" the hole thing split and destructed again /forums/images/graemlins/mad.gif and this time I did not evan raise or lower the FEL - only turned the power steering??.
On further investigation I have discovered that the "male" quick connect on the FEL line has some pitting and damage around it, was more difficult than the others and seemed ? loose when snapped together- it also seems to be older that the rest as it was installed with thread sealant tape??
My question: /forums/images/graemlins/grin.gif Was it possibe that this fitting caused the snap coupling to not work properly - hence a build up of pressure in the pump and no immediate safety valve between pump and FEL to avoid the destruction of the pump??
Any advice please - As I am rather nervous about installing another pump and going for it again??? <font color="blue"> </font> bradsan@bigpond.com.au
