Take out the grease fitting instead? On a side note, had an old Deere 450 Dozer with a stuck track adjuster, same type but bigger. Wouldn’t take grease. Took it off and put it in the hot water parts washer at work. 1/2 hour later heard a loud bang. Split the side of the cylinder wide open from the grease inside expanding when it got hot because it couldn’t extend due to rod being seized.
