John N. Packard Posted May 24, 2002 Share Posted May 24, 2002 I'm trying to remove the differential universal joint flange on my '54 Packard Patrician. Any suggestions as to how to bust the nut loose that holds it to the pinion shaft? Thanks!<P>jnp Link to comment Share on other sites More sharing options...
fordee9r (Ron Springstead) Posted May 24, 2002 Share Posted May 24, 2002 Hey John,<BR>In my shop we use a good quality impact wrench and an impact socket. If things get stubborn, we let the compressors pump up to their maximum of 150 psi, make sure the gun is freshly oiled and set at its maximum torque setting and try again. Usually this is all it takes.<BR>If you don't have the luxury of this in your home shop, I guess I'd try everything I could think of to keep the rear wheels from turning (emergency brake, etc.) and have at it with a breaker bar and a length of pipe!

Guest Posted May 25, 2002 Share Posted May 25, 2002 use a LARGE (crescent or pipe) wrench on the pinion yoke to hold it while turning the nut. Think of the pinion yoke as a large square nut. Place the daigo wrnch on it. If the nut is real tight u mite need to use a 3/4 drive socket and breaker bar. If its a round flange then u will probably need to use a pipe wrench on it.

John N. Packard Posted May 26, 2002 Author Share Posted May 26, 2002 Well, I've tried both suggestions with no success!. Put some WD-40 on it and will let it sit overnight. I guess I'm getting weak in my old age. I used a 3/4 inch breaker bar and an extension pipe. Held the yoke with a wrench and extension pipe against the floor of the garage. It just will not break loose. The impact wrench made a racket but didn't budge it either. I could only get 120 psi. <BR>jnp Link to comment Share on other sites More sharing options...
Guest Posted May 26, 2002 Share Posted May 26, 2002 check the manual to make sure its NOT a left hand thread or something. Should NOT be a left hand thread tho. Link to comment Share on other sites More sharing options...
Guest Randy Berger Posted May 26, 2002 Share Posted May 26, 2002 John, I emailed you with a picture of Packard's joint flange tool to give you an idea how they did it. I like the impact gun at full throttle - it was the only way to loosen my vibration damper bolt. <BR>YFAM, Randy Berger Link to comment Share on other sites More sharing options...
John N. Packard Posted May 28, 2002 Author Share Posted May 28, 2002 Got the nut off today! A little more WD-40 and a longer extension pipe broke it loose. The pinion seal is replaced and the yoke flange reinstalled. Thanks for your help!<BR>jnp Link to comment Share on other sites More sharing options...
Guest Posted June 6, 2002 Share Posted June 6, 2002 did you use a beam torque wrench before removing the nut to observe the rotating torque? after replacing the seal you torque the nut until the rotating torque is matched.<BR>saves crushing the bearings balls into the race.
