Hi All Can anyone tell me if the boom cylinders have a replaceable bush at the top pivot point where the boom pin is? The parts diagram shows a bush at the bottom pivot but not at the top. Also, has anyone fabricated their own replacement pins to save paying for genuine ones? I'm in Australia and we pay around 3 times the price for parts here. Finally, I also need to replace my boom cylinder seals. Apparently for the LX565 there are 2 types of cylinders - a retaining ring gland type or a threaded ring gland. Is there any way to identify which one I have without pulling it apart? My LX565 is one of the older ones but I don't know which year it is.
