peter lena 8,627 #2 Posted October 22, 2021 @TJ salyers got a piece of solid round stock that would snug in there ? with internal wall support on that stub , a 24" pipe wrench with oil soaking thread area , will probably walk that right out . use pipe wrench tight to base , use a 3 lb hammer , on the center back area of of wrench , one solid hit , with no hammer bounce , will move it , pete 1 Share this post Link to post Share on other sites
oldlineman 1,481 #3 Posted October 22, 2021 You could also use a hacksaw blade and CAREFULLY split the pipe being careful not to cut the block threads and collapse the pipe nipple with a small chisel and small hammer, being careful of the cast iron block. Patiences will be your friend! Bob 1 2 1 Share this post Link to post Share on other sites
lynnmor 7,306 #4 Posted October 22, 2021 (edited) Run a hacksaw blade in and out till you just start to touch the threads, that will weaken the pipe so that it collapses a bit. oldlineman was quicker on the trigger.

8ntruck 7,004 #5 Posted October 22, 2021 If you do cut the pipe, make sure the hacksaw teeth rake the metal chips out of the engine. Maybe some grease on the hacksaw blade to make the chips stick to it would be a good idea, too. 1 1 Share this post Link to post Share on other sites
stevasaurus 22,739 #6 Posted October 22, 2021 Cut the nipple off straight, leaving about 1/2" sticking out. Take a cold chisel and a 2 lb ball peen hammer, place chisel perpendicular to engine and tap firmly with hammer. The nipple will cave in easily and you can turn out with a pair of pliers without ruining threads. Use new nipple to chase threads...turn in and then back out a little at a time (like it was a tap). 5 2 1 Share this post Link to post Share on other sites

Have it sucking the chips out as you cut. 1 Share this post Link to post Share on other sites
Snoopy11 5,714 #8 Posted October 22, 2021 Is that... steel? I'd be welding on it in a heartbeat... LOL Don Share this post Link to post Share on other sites
TJ5208 1,824 #9 Posted October 22, 2021 Yes it is galvanized steel pipe Share this post Link to post Share on other sites
Snoopy11 5,714 #11 Posted October 22, 2021 Yeah, if all else fails, I would weld in a bolt, or a BIG OLE NUT on the threaded pipe, so I could get a socket on it... maybe even some other type of device to get the thing turned out... rather than all the cutting. But... that's just me... Don 1 Share this post Link to post Share on other sites

All different sizes... two of them are well over 100 years old. One from a railroad, late 1800s, one from WW I, govt issue.

stevasaurus 22,739 #13 Posted October 22, 2021 TJ, you could put a chisel on it the way it is and have it out in 1 1/2 minutes. Really easy and the best way to do it. 3 Share this post Link to post Share on other sites

Oh yes, not arguing with you, Steve, I did see your comment above... I just gave input, in case the chisel idea did not work... (I would not cut anything... that close to the engine... for fear of metal shavings... but that is just me... Don 1 Share this post Link to post Share on other sites
stevasaurus 22,739 #16 Posted October 22, 2021 The thing about those nipples, they are usually so thin that a pipe wrench can collapse the metal and rip it and still leave the threads in the engine. When you use the hammer and chisel method, you collapse the threads in the engine enough that they break loose and turn right out. 3 2 Share this post Link to post Share on other sites
JimSraj 429 #17 Posted October 23, 2021 I’d be soaking the threads with a good penetrating oil a number of times a day for a few days to start no matter which of the suggested methods you try. There is a tool called an internal pipe wrench too. Good luck. Share this post Link to post Share on other sites
adsm08 2,057 #18 Posted October 23, 2021 (edited) Well, this doesn't help a lot now since you have it all hacked to bits, but I usually start by melting some anti-sieze into the threads with butane or propane, then I TIGHTEN it an 1/8th of a turn or so. Then I back it out, usually without much of a fight. Edited October 23, 2021 by adsm08 Share this post Link to post Share on other sites
