dhr5050 0 #1 Posted October 29, 2017 Hello everyone Below is a picture of a stud I can't remove. I was wondering if anybody has had this problem and how they dealt with it? Also, I think this is the 7/16 stud ( #104842)..not completely sure though because I can't find any pictures of it anywhere other than some detail lacking diagrams Share this post Link to post Share on other sites
daveoman1966 3,612 #2 Posted October 29, 2017 First, buy the penetrant oil named FREE-ALL. Kinday pricey, but works well. Spray generously onto threads and let soak a couple hours...spray again if wanted.. 2nd...use a pair of LOCKING vise grip pliers on the short stub, as close as possible to the crankshaft. LOCK THE PLIERS as TIGHT AS POSSIBLE. Then, give the locked-on pliers a WHACK to 'impact' the stud, hoping to break it loose. If that fails, try again, but this time...USE A HOT WRENCH to heat up the END of the crankshaft...thjen whack the pliers again. (You should wrap a wet rag around the crankshaft up against the block to spare the bearing and seal from heat.) If all that fails, cut the bolt off flush and drill a 5/6-3/8 hole in the center of it...at least 1" deep. Then get the EZ-outs ready and try that. 4 Share this post Link to post Share on other sites

gwest_ca-(File Mod) 10,503 #4 Posted October 29, 2017 You can also eliminate all those parts that push the pto bell out if you replace the outer pto shaft in the outer bearing to a newer design that used 2 snap rings - one each side of the bearing. Then the pto lever and rod will pull the pto out. Pto shaft item 33 2 snap rings item 34 If you do this just cut the broken stud off flush. http://www.partstree.com/parts/toro/mowers-lawn-garden-tractor/31-12k801-312-8-toro-312-8-garden-tractor-1990/pto-clutch-and-control/ Garry 3 4 Share this post Link to post Share on other sites

Searcher60 208 #6 Posted October 30, 2017 If you have to ask, then apparently you do not have the tools or experience in removing these. Take it to a machine shop, they can get it out without damage to crank. 2 1 Share this post Link to post Share on other sites

If you have a bolt/stud broken off close to, or just below the face of a casting, etc, find a washer with a hole the size or slightly smaller than the bolt, hold it over the bolt, then hit it with the mig. The washer should stop you welding the bolt to the casting. Then hold a nut, a half / thin nut is best, over the washer / bolt and fill the centre of the nut with weld. This usually puts enough heat into the assembly to allow you to crack it free. Good luck 3 1 Share this post Link to post Share on other sites

Considering none of us were actually born with all the knowledge needed to perform these repairs, all our tractors would be sitting in a shop. You had to learn too. Excuse me if Im wrong, but' I also thought learning & teaching each other about our tractors was the sole purpose of these type websites anyway, maybe even save them from Americas scrap heap but I guess you don't understand that idea? 3 Share this post Link to post Share on other sites

Agreed. I dont mind giving out suggestions. Not my junk they're working on! Plus, some of you guys have GREAT ideas that I can tuck away in my "maybe there's a better way " file 😎 1 Share this post Link to post Share on other sites

123GO 78 #13 Posted July 20, 2019 Well' I certainly wasn't aiming high for everyone, by all means it was a single shot. I agree "Sole" purpose was strong because your right we all enjoy each other's daily dose of BS here too. Fwiw- I took my today, kick'n back watching tv (Blazing Saddles) due to rain and wth its a Saturday. All good for now, unlocked unloaded. Sorry folks..lol 1 Share this post Link to post Share on other sites
