Stud extractor recommendations.
« on: 02 April 2019, 08:37:28 PM »
In the next week or so I'll need to replace the exhaust studs on my Triumph. The nuts will be a nightmare to get off, having been in place for over 20 years. The stud threads are corroded so figured on changing them all, whilst the exhaust is being repaired. A Beta 8mm roller stud extractor has caught my eye. Does anyone have any experience of this type of tool or any success stories with any alternative. Thanks in advance.

Dont envy you with this task. Plenty of release agent on them for a few days first. Used several types of stud removers over the years, none stud out for me. Just as much success with two nuts locked together on the stud, if youve a welder, you could try tacking the nuts on and using them to unscrew, sometimes the burst of heat helps free off the studs

Thanks agricola, the welded nut is an option as the threads don't look too clever, but have not had the time to examine properly. Was hoping there was some magic tool out there, that I'm not aware of, that has a good success rate, maybe used with an impact driver/air wrench.

But really Robbo, how bad are they ? maybe run the bike to get it hot then use that freeze and crack stuff. so big temp difference. do the studs need doing? or just got to get nuts off ?

Deadeye had good luck with an impact driver and a stud extractor. He gave a link in post 49 on this thread http://foc-u.co.uk/index.php/topic,5990.25.html
I printed out DUDE'S instructions...even on paper they are pretty confusing...Has he been INGESTING some MIND ALTERING substance......???

The adjustable extractor that Deadeye used is a consideration. The Beta one comes in individual sizes. At least I've got a few options now for when I do get the time to get this done.

did a full set of exhaust studs i used a decent pair of mole grips and a medium size hammer--gently rock the stud whilst tappingthe end with the hammer dont be afraid to give them a good crack your going to replace them anyway--always had 100 percent success rate with this method --

Thanks Dinger and jimjenko for your suggestions. I'm only at the daily squirts of Plusgas stage at present, but now have a good few options to try. Thank you all.

I'll post the pictures of the exhaust studs I had to get out when I get home, but use plus gas type stuff, then when you are ready, give each stud a good whacking, put the barrel/roller extractor on and they should come out. I would recommend removing the rad completely and anything else that interferes with the swing of the hammer. I got every one out except the one I didn't smack, I had to drill and tap that one.

Well to make matters worse,as my bike is a very early one, although the studs are 8mm, the nuts could be either 12 or 13mm spanner wise. They're not in a good way so have got a set of hammer on nut extractors from Screwfix. Yes, definately remove the rad as hammers and motorbikes are not a good combination. Got some decorating to get finished, then this task will have my undivided attention. The photos would be helpful if it's not a problem. Thanks :thumbup . What make of stud extractor did you use?

I used a cheap Lazer one from eBay. Worked perfectly. I will put the photos on, they are already on here actually, just don't know where. It looked like the bike had been kept at the bottom of a salt mine.

Thanks again BB, the Lazer is very similar to the Beta one I'd read about. When I get started, if I remember, I'll take some pics to plot the progress.....or lack of :lol .

Made a start on removing the headers from my Triumph. Fortunately after a good Plus gassing on the lower radiator fixings, the rad came off relatively easily. Made a start on the header bolts with the Erbauer nut and bolt remover set. Was well impressed with that and have got 4 of the 6 nuts off complete with the studs. It looks as though the spanner size, beneath all the rust, is 10mm, which is very small for an 8mm stud. I might struggle with the remaining 2, as the smallest remover socket in the set is 10mm, but tomorrows another day. Don't want to get too confident yet.

And all the studs came out except the one i didnt clout with a hammer. There were some that had wasted away on the diameter so that they were only half what they should have been. They still came out.

Thanks for posting the pics BB, very similar to my scenario. Got 4 out complete with studs, but failed with the other 2 having to resort to the Dremel. Not able to do the back to back nut trick as threads too badly corroded. Last question hopefully,did you use a dedicated sized extractor or one like Laser do that covers something like 6 to 12mm. Just wondering if that would be better as the 8mm stud, isn't 8mm any more, if you see what I mean. :lol

I used a barrel and cam type from Lazer. Only cheap but worked a treat.

Ordered a Neilsen extractor which covers sizes 6 to 13mm. Off to the exhaust guy tomorrow to get a quote for the repair.

Just a quick update. Extractor arrived today, out to the garage and both studs out within 5 minutes......phew. Off to the exhaust guy tomorrow to collect that, so somethings gone right for me for once.
I decided on an adjustable extractor as couldn't be certain an 8mm socket/roller type would fit firmly enough due to the studs being rusted. The one I bought resembles a drill chuck so the harder you try and undo the stud, the tighter the jaws grip it.
Thanks Billy Balthorpe for posting the pics and for all your advice, whacking the engine with a hammer took a leap of faith though :lol:thumbup :thumbup
