I can稚 tell you what it痴 for, but it is an aircraft part. Problem is, I can稚 get a new bearing, but I need the bearing removed to mag particle inspect the shaft. We need to be able to inspect and reuse the bearing. The lead time to get a new certified bearing is almost a year.
Cost of tools isn’t an issue. The customer will pay for it.
No loophole that I have ever seen to buy parts from an unapproved vendor that hasn’t gone through the procurement process to properly certify the part meets specification.
I am not happy that I have been asked (told) to do this by the muckety-mucks on high to get these planes in the air.
There is a contract with a vendor to build new units, but they wont deliver for another year. This is a stop-gap measure to “overhaul” these things as best I can.
I have a full machine shop, so I think my plan today will be to make a bearing separator out of delrin so I don稚 damage the shaft.
In combination with heat/cold I think that gives me the best chance of getting the bearing to move a little so that a thin collet type puller can get behind the inner race and put it off.
You're doing A&P work and asking for help on a tractor forum? My motto here is if I can't fix it I'll smash it!
I own an aerospace certified machine shop, and you are correct, being able to purchase from a new supplier that is not on an approved vendor list is a no-no. However, if I was doing this repair, I would elevate the situation within my customers chain of command and let them know that destroying the bearing is almost a given and that there needs to be an alternative course of action.

I have a problem I have thus far been unable to figure out and I知 wondering if one of you can give me an idea how I can remove this bearing without causing any damage to either the bearing or shaft.

The space between the bearing and splined area is so small a standard bearing separator can稚 fit between the bearing and splines.
I broke one bearing trying to hold it in a vice so I could press out the shaft.
The bearing is a press fit on the shaft and it took a about half a ton of pressure to get the inner race of the broken bearing off the shaft.
Is there a special tool that could help me?
