Stud Extractor
I'm looking to buy a stud extractor/installer. Can anyone advise on which type to get? I usually use the old two nut method but wanted something to speed things up a bit. It's not necessarily for broken studs, just a quicker way of removing/replacing any stud.

Re: Stud Extractor
I have a set of these Mart, they work really well. Self grip rollers so they don't damage anything unless the stud is seized. https://www.ebay.co.uk/itm/233340606311 ... SwO3Vde7Bb

Re: Stud Extractor
Thanks Tony
I was looking at these:-

...but I thought they would probably chew up the stud? OK for broken studs though.
I have now ordered a set like yours.

Re: Stud Extractor
I have both types; the concentric roller type are best, but if the stud has any resistance to being removed, they each can flatten the threads. If I have any aspiration to re-use the studs I'll double nut them.
The cam type needs space to operate and can be awkward on a sprint head as the cam bearing cap bolt heads are in the way of its locus.

Re: Stud Extractor
Arrived today and I immediately used them on a couple of O/Ds I'm rebuilding for a club member. I wish I'd got a set years ago.
Something else I should have bought years ago arrived today as well, a cordless ratchet.

Re: Stud Extractor
I just bought a cheap cordless 3/8 drive ratchet as well off ebay.
I went to see Dan Brown at the weekend to get the clutch changed on MSO, just getting all the tunnel bolts out is worth it alone, great bit of kit.

Re: Stud Extractor
I didn't know AC Delco made power tools Mart?
They made some good batteries back in the day. I remember my Dad's old 1990's Vauxhall having a Delco 'freedom' battery and it was never replaced in the 10+ years Dad kept the car.
A useful tool I'm sure - enjoy!

Re: Stud Extractor
I've just been stripping down another Sprint engine and was using the new cordless ratchet. Why oh why have I waited this long to get one,
especially on all those sump bolts.

Re: Stud Extractor
Hi Mart, apart from the obvious not needing an airline or compressor whats the benefit of having a codeless one?

Re: Stud Extractor
It wasn't necessarily the "cordless" part, just having a power ratchet at all has made things easier/quicker.
