In Reply to: Removing the #546 Yoke and #547 Spring posted by Dave(CO) on May 16, 2019 at 13:54:20:
Sorry, but not that simple. You have to un-screw the yoke from the draft control plunger which is inside the spring and it is pinned to the internal hydraulic linkage. Usually firmly rusted threads from 70 years of rusting. Generally oxy/acety heat required to remove. Too much force and you will damage the hyd linkage. Might want to re-think, "just how bad do I want to remove that?".
