I recently picked up an Atlas 7B shaper, Serial Number 12297, that seems to be in reasonably good condition, but it spent a long time sitting oily in a wood shop. And was used with some sort of coolant that appears to have polymerized. There have been a number of minor problems I've dealt with with (new gib for the tool slide, new brake pulley), but I have now run into an impasse.
Before I start using the machine, I want to clean, check, and re-lube the rolling element bearings on the bull gear and pinion shaft. I'm into the feed and ratchet assembly on the bull gear shaft, and cannot remove the collar S7-114 that is in front of gear S7-86. I really need to remove the gear(which doesn't appear to be original) as one of the screws that holds the S7-64 bearing plate in place backed out and got caught on the back of the gear.
I've tried penetrating oils of various sorts, heat, padded locking pliers, etc. with no success. Is the S7-114 collar just a plain shaft collar or are there threads or something I'm missing? I don't want to get too forceful in that area due to the Zamak parts, but if it is a simple collar, I may just cut it off and make a new one. Or perhaps use a small bearing splitter?
Advice from someone more experienced with these machines would be appreciated.
