I was putting seals in a pair of JD loader cylinders for a customer today. It is on a 30 HP or so newer (3 years old) compact tractor. The pistons on both cylinder rods were able to move bout 1/2 inch back and forth. there was also no apparent seal between piston and rod so oil could somewhat easily move between the two sides. I have had plenty of cylinders apart but have never seen this (piston always tight on rod and usually some sort of o ring sealing between rod and piston. Does anyone know why they would be designed this way? There were threads down past the face of the piston and the nut was only turned on far enough to allow this 1/2 inch movement. The one nut was finger tight but the other had red loctite on it. Any Ideas?
Thanks,
Andy
