ebinmaine 72,424 #1 Posted May 3 I have a 1978/9 C141 Automatic parts tractor that I'm trying to remove and save the well known stubborn rock shaft from. This machine is VERY rusty. I got the left side step off, outer sheet metal. Worked at getting the hydraulic cylinder off. It was frozen solid to the step support rod. That's done. I now have the rock shaft pins out and it's floating between the steering tower sides. What's the best way to free up the two pieces of the rock shaft? 1 Share this post Link to post Share on other sites
MainelyWheelhorse 1,461 #2 Posted May 3 @ebinmaine some favorite type of penetrant and heat possibly? Usually just the penetrant works for me. Once it gets worked in it might loosen things up. 2 Share this post Link to post Share on other sites
SylvanLakeWH 28,325 #3 Posted May 3 Big penetrating juice Bigger hammer Biggest heat Repeat... (I know, it's not a haiku ) 5 Share this post Link to post Share on other sites
squonk 43,734 #4 Posted May 3 (edited) Since it's a parts tractor that's rusty, cut the rock shaft out of the tower. Get it in a vise and heat / quench it. Might take a couple tries. I watched Taryl's video and have done it a few times and am amazed on how well it works. Edited May 3 by squonk 4 1 Share this post Link to post Share on other sites

Never removed one so I never paid attention to what they were made of. Just a warning about heating cast parts 3 Share this post Link to post Share on other sites
gwest_ca-(File Mod) 11,449 #10 Posted May 4 Can you cap/plug the two pin holes on the bottom so penetrant can be applied there also? 1 1 Share this post Link to post Share on other sites

I haven't actually purchased it myself in yeeeeaaars. The cylinder bottles I had/have are all older ones I've inherited. What's the hottest one can get for a small hand torch nowadays? 1 Share this post Link to post Share on other sites
squonk 43,734 #18 Posted May 4 I bought a small Oxy /Acetylene torch set from Horror Fright about 4 years ago. About $350 and have only used it a few times but enough to need to get the tanks refilled. YES they are cheaply made. YES the tanks are expensive to refill. BUT the time and aggravation they have saved me getting something apart, bending some thing or brazing some tinwork together has been worth the cost. 3 Share this post Link to post Share on other sites

"Eric and BBT's Tractor and Stove Restoration" I had commercial accounts even before I got my DBA years ago. Pretty easy. Or does Maine really restrict such activity? Here I walk into Air Gas with an empty tank and they give me a full one. all they need is a name on the ticket. Edited May 4 by squonk 3 Share this post Link to post Share on other sites

When I was working at Napa we had all kinds of customers with accounts and we were an AirGas exchange station. Farmers or Joe Blow off the street. I opened an account without any business records or tax exempt status. I only got my DBA when the work I was doing at night got so big I had to work out of another shop. All kinds of folks came into the store with accounts with no business license or Tax I.D. 2 Share this post Link to post Share on other sites
953 nut 59,774 #23 Posted May 4 In Florida and North Carolina you can exchange oxygen, acetylene or the CO2/Argon cylinders without any paperwork other than cash or credit card. I got rid of the 20CF oxygen/10CF acetylene tanks years ago. The cost to fill them was too high for what you were getting. I now have the 80/40 sizes, the cost per exchange has gone up quite a bit but is much less than the cost per CF of the little ones. Those little tanks always seemed to run out at the worst time. 3 Share this post Link to post Share on other sites
squonk 43,734 #24 Posted May 4 I got used to the little tanks when I had to rope them up to the roof all the time or when needed the torch in a kitchen to repair refrigeration equipment. Had spare bottles on the truck. Nitrogen was the worst. We went through that stuff like water 3 Share this post Link to post Share on other sites
