Sa250 shunt coil problem

[connor5231]

I have an sa 250 code #8306 and was pressing out a shunt coil and busted the iron core piece that sits inside the coil. It’s broke bent and pretty chewed up on the side that fits into the housing. The housing is fixable I just need to replace the piece that the coil sits on. Asking for some advice before I try to rebuild it thanks in advance

A photo would help.
It maybe a simple problem but a set photos would show how to replace the part.

Yes, I also have no idea of its dimensions and can't suggest where to get a replacement; is it solid iron? The cores used on AC transformers use special high-silicon steel, but if yours is a DC coil, you may want an alloy that retains magnetism.
It may take a few days, but you should get some responses from members who know both the equipment and the electronics and may even know where to get what you need.

There are a couple vendors for parts I think, Bills Repair maybe? They might even have used piece.

Will be a pain to find.
You need find someone parting the SA250 and hope they have a good one or repair the one you have.

Hoping I can straighten it out, clean it up re weld it and if it fits back in Never see it again. Not sure how exact the core needs to be so it might work fine

Did you press that out or beat it out with a sledge hammer?

I agree with Sberry on checking with Bill's Welder Repair or other well known repair/parts vendors for a used piece. You're dealing with a core-to-armature clearance that the deformation may create a significant problem.

A simple fixture and 20T press makes the job much easier and damage free.
