Broken bolt

[bobk]

Right so the bearing went on the needle carrier on the baler .
Easy enough to replace the bearing , 2 hole 40mm bore pillar block , however one of the bolts has broken off and it's captive nut ,

Any ideas , ?

Drill the guts out?
Heat the housing and weld a nut to the broken stud?

It's broke off flush with the nut inside the baler

Not the easiest place to take a photo let alone get it out

Drill, PlusGas and a quality extractor tool.

Guessing you wont want to spend 100 quid on a Rigid/Snap on extractor set then.....

I'd put a washer round it to protect the parent metal. Spot of weld in the centre. Keep spotting until you get a nice dome that a m12 or m14 nut will sit on. Then weld nut to dome. Should turn out when it cool

Just cut a hole in the side, cold chisel may remove the captive nut. If me I would just cut it out and weld a fresh bit of plate with captive nut welded in situ and then clean up the welds with a flap disc. Sometimes you can bugger about for hours drilling them out only to bugger up the threads in the nut. Depends if you can weld?

Access is terrible , not too bad to get at the bolt but very tight to cut a piece out of the side .
My initial thought was to weld the bottom of the bearing casing to the frame , but I would like to do it properly if poss

Get a left hand 10 mm bit and drill it out, if you are lucky it will drive it through

This above is good,

Failing that get a good drift and flog it to break the weld on captive nut, and replace with a Rivet nut

What's a rivet nut ?

What's a rivet nut ?

Like a heavy rivet with a thread down the middle. Great for light fixings, panels etc.

These were fairly tight to get out , I'm thinking a stud extractor won't hack it .
Your suggestion about welding it up is feasible but it's broken below the thread of the nut .

weld the center of the washer
