For sale is a REBUILT OR NEW? BUCKET CYLINDER FOR HITACHI 800 EXCAVATOR. I am not sure if it was used or not, I am guessing it was a rebuilt item. I was told the same by the person at the auction of a bankrupt excavation company. 104" Overall length (+/- 1/2"). Cylinder body is approximately 8-1/2" in diameter (+/- 1/4"). Cylinder is approximately 5-3/4" in diameter (+/- 1/8"). Diameter of through-hole on end of extending cylinder is approximately 5-1/2" (+/- 1/8"). Diameter of through-hole on non-extending part of cylinder body is approximately 5-1/8" (+/- 1/8").
