Darbone85737 Posted October 6, 2014 Report Share Posted October 6, 2014 I had previously asked about a part number for the shaft seal and you all came to my aid. Thanks I have the seal. Now- I'm unable to get the nut off the transmission output shaft to get to the seal.. I'm using my air impact tool with a 11/4 socket and it doesn't budge. I soaked it in Blaster and tried heating with a propane torch. Nothing. Any hints or tricks as to how to get the nut off would be appreciated. Once again thanks for the help. I'm hoping someday I'll learn enough to help someone else out Larry Quote Link to comment Share on other sites More sharing options...
suntennis Posted October 6, 2014 Report Share Posted October 6, 2014 If you are using a air impact wrench, did you try increasing the psi to the wrench? I had a problem once trying to remove a head bolt and tried to tighten the bolt then remove it. For some reason this allowed me to remove the bolt. If the transmission is still in the car, you would want to have reverse or first gear selected. Quote Link to comment Share on other sites More sharing options...
Darbone85737 Posted October 6, 2014 Author Report Share Posted October 6, 2014 Thanks for the response Transmission is out of the car. I just rebuilt the engine and it's now back in waiting for the transmission to join it. I can put enough tension on using the emergency brake lever to keep the shaft from spinning. I have 110 psi out of the compressor. Quote Link to comment Share on other sites More sharing options...
DJ194950 Posted October 7, 2014 Report Share Posted October 7, 2014 Sorry, but have to ask, what is an 11/4 socket? Does whatever socket your using fit tightly on the nut? Is the Impact wrench new or old? Try tightening the nut first (as per suntennis) which will help break the old rust etc. loose and put some oil into the impact wrench before use. Just holding the drive line flange with a rag as tightly as possible should do the job as long as your 1/2" impact is not worn out.

Darbone85737 Posted October 7, 2014 Author Report Share Posted October 7, 2014 The nut is 1 1/4 inch and the 1 1/4 inch socket fits tightly on the nut. The impact wrench is a couple of years old but maybe I'll borrow one from a friend just to see if that helps. I did try a quick tightening just to make sure tit wasn't a left handed thread. Didn't make a difference Thanks L Quote Link to comment Share on other sites More sharing options...
james curl Posted October 7, 2014 Report Share Posted October 7, 2014 You will need around 120 psi in air pressure to drive a 1/2" impact at high torque. Be sure that your compressor has enough capacity with out running low on air pressure. My compressor does not have enough capacity to run mine for more than one wheel before it has to build back up. Some air tools need and use a lot of cfm to work as designed so it might not be your impact wrench. Quote Link to comment Share on other sites More sharing options...
casper50 Posted October 7, 2014 Report Share Posted October 7, 2014 try a breaker bar. Quote Link to comment Share on other sites More sharing options...
Darbone85737 Posted October 7, 2014 Author Report Share Posted October 7, 2014 I'll try stepping up the psi. If that fails I'll try the breaker bar. Quote Link to comment Share on other sites More sharing options...
Solution Darbone85737 Posted October 7, 2014 Author Solution Report Share Posted October 7, 2014 Got it done. Brought the transmission to a friends auto shop. Zipped it right off using his air wrench. I think the problem was lack of CFM. Lesson learned and thanks for the help L. Quote Link to comment Share on other sites More sharing options...
Don Coatney Posted October 7, 2014 Report Share Posted October 7, 2014 Glad you got it. Not only is CFM an issue but volume is an issue as well. I added an air reservoir to my compressed air system and it makes a big difference in oomph when running air tools. Quote Link to comment Share on other sites More sharing options...
Darbone85737 Posted October 7, 2014 Author Report Share Posted October 7, 2014 Transmission seal has been removed. Pulled the rear flange and drum with puller, took out the old seal and replaced with new. Took about 1/2 hour. This is why there was always a small pool of gear oil underneath and why the emergency brake never worked. 1 Quote Link to comment Share on other sites More sharing options...
