Have a siezed pin on the trim ram on my DPH-A. They can be pigs to get out but with effort, penetrative oil and rotation they shift. Got one drive off ok, but one pin on the other drives refuses to come out. Cannot rotate it even with the usual clandestine tools, wedges and knocking sticks. It's an older pin as well without the hex head making it substantially more difficult.
So question - anyone used an induction heater? Seems safer than naked flame. Also would you heat the pin or the housing? I would have thought you would heat the housing and then try and drive the pin out whilst the housing is hot. But I've also heard that if you heat the pin and let it cool naturally, it shifts the corrosion a bit a you have a casting and stainless pin with differing expansion rates, allowing you to drive it out cold.
