Bandit 1590xp bottom feed roller bearing on hydro motor side. any advice on how to get the pin out that connects hydro motor to feed roller shaft? to make matters worse, the last time this pin was replaced they welded it in. i plan on repacing feed roller so only need to salvage pump side. someone told me i can cut the coupler just on the motor side of pin to remove pump/motor from coupler. thanks for any help!!
