Okay... First post - be gentle!
I've recently purchased an old EX200-2. It is still fully functional, however the boom cylinder moves around 2cm before 'engaging', implying that the pin and/or bush are worn well beyond tolerance.
I'm attempting to replace the bushes and pins on the boom cylinders (the pin that connects the boom to the frame). I've removed the retaining/stopper pin and managed to move the main pin around 1-inch using a pry bar. Beyond that point it appears to be stuck! I'm using a pry-bar with a 1m pipe on the end to move the pin and it moves nicely until it hits some sort of catch at the 1 inch point... I've had a second person slowly move the boom cylinder in and out while I'm hanging off the pin with no joy.
The workshop manual was not-so-helpful, with the instructions summerised in a single step: "Remove rings, stopper pins and, pin"... There don't appear to be any special tools.
Has anybody experienced this before? Advice?
Regards,
