Changing my trans-axle fluid on my cub cadet z-force 17AF3AGV010, one side did remove a little hard but did loosen, other side I thought was starting to break loose but my 1/4" hex socket spun and damaged the inside of the vent cap hole, now my 1/4" is too loose. Has anyone taking these vent caps off this any other tools or techniques? I was thinking maybe heat the vent cap first then try a small pipe wrench or vise grips, maybe buying a bigger hex socket and grind it down, then tap it into the damage cap hole? Any advice would be greatly appreciated...
