Sleeve/5-piece bolt removal

Here is a quick overview of how to remove a 3/8" sleeve bolt also called a 5-piece bolt. These can be finicky to remove, and require additional tools. New bolts are much easier to remove than old rusted bolts.

Great video 👍 very helpful. Do you know the TPI for the 5/16 portion of the draw stud? Also, where do you get that draw stud?

The 5/16 section (and cone for 3/8" 5-piece bolts) is 18tpi. I make the draw studs using a drill to spin the tip of a 3/8"x16 double ended manifold stud against an angle grinder, and then use a 5/16 x 18 die to cut threads. its helpful to also grind flats on opposite sides of the stud so you can use an adjustable wrench on to screw the stud on/off couplers or into the bolt sleeve. the studs are available on McMaster www.mcmaster.com/90281A644/ or amazon www.amazon.com/gp/product/B000CZ3JWY/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&psc=1

I need to remove one expansion bolt from the Transmission Mount, since I want to replace that mount. In the car 2003 Chevy Cavalier, the Transmission Mount is attached to the subframe with 3-4 usual bolts and one expansion bolt, which is located at the center of the mount. No films about that process in details, but I saw one film where the author broke that expansion bolt on Chevy Transmission Mount. Please could you tell if the procedure of the removal of the expansion bolt on a car would be the same, as in this film? Do I also need those special tools to remove it? I have a Shop Manual for that car, and on the replacement of the Transmission Mount they don't say about any special tools, just say: Remove the Expansion Bolt, then remove other bolts. I would appreciate any opinion on this matter. Thank you for the great film.

Sorry, I’m not familiar with expansion bolts in automotive applications, but I’d guess this process would further damage the car. You might check out the South Main Auto channel. He has lots of good videos and I’d guess one covering what you need.

@@westernadventureinstructio9227 Thank you very much for the attention to my question. During my research on this question I found out that the Expansion Bolt on Chevy Transmission Mount is a type, which is cold Pipe Bolt. From Ebay they wrote me that no special tools needed, just a regular wrench. They also advised to relieve the stress from the Transmission before dealing w/that Bolt, then it is kind of easier to remove it. If you look at that bolt you see a head of the seemingly usual bolt, like for 10 mm socket, not a nut, which you can remove. But it is sitting inside of the black plastic well. The film, which points on the problem can be found if to type on YT "2003 chevy cavalier engine transmission mount". It is a film of the author Efurd Garage, he explains the problem, and you can briefly see that bolt. It is the only film on YT which addresses the problem. The author corrected the broken bolt w/welding, I don't do welding and won't be able to correct it that way. I feel that the Chevy is the only car w/that type of attachment of the Transmission Mount. I find it is very and very rare thing: Expansion bolts in automotive applications. Thank you again for your concerns and advise w/South Main Auto channel. I'll check, and hope to get another piece of some info on this question. The project seems to be an interesting indeed.
