Stuck Main Shaft on 12A
Posted: Mon Jan 29, 2024 4:59 pm
Good afternoon all,
I, like many before me... have a stuck main shaft in my 12A (disassembling everything else went well enough, minus the cracked cast iron inner hub... grrr). Because of this I decided to take the main shaft out (continuing to use the 3-jaw puller would've finished the job and it stopped moving anyways) and press it out with the 100T. Here's the problem... now the bearing is stuck.
I do believe by biggest issue is that the little allen-key / hex combo on the underside of the snout broke clean off (bearing retainer, correct?). I swear I just looked at it and it fell off. Its hardened steel and drilling it out went nowhere.
I've given it a good soak in penetrating fluid, and used a small slide hammer - but she's not budging.
Thoughts?
Also, I could quite easily braze the hub crack, good idea or am I asking for trouble? For the most part, parts for 12A's seam to be available hey?
Thank you!
Cheers,
