Guffin Posted December 24, 2005 Share Posted December 24, 2005 I am trying to remove the drive shaft from the pinion shaft on a -53 rear end to put on my 40-56s. I can' even get the rivet out which is the first thing to do. Please, someone who has done this, help me.Jan Link to comment Share on other sites More sharing options...
old-tank Posted December 25, 2005 Share Posted December 25, 2005 After filing or grinding the peened end of the 1/4 inch pin use a hardened flat nose punch with a BIG hammer. Be sure everything is supported so you don't bend the pinion shaft or driveshaft. There is probably a way to do this with a press also.After you get the pin out you will find that the driveshaft is pressed onto the pinion shaft. I made a tool to remove and replace and can post pictures if needed.Good LuckWillie Link to comment Share on other sites More sharing options...
Guffin Posted December 25, 2005 Author Share Posted December 25, 2005 Thank you Willie. After grinding off the peened end I cant se the contour of the pin! It seems to fit so snug so I can't where the pin is. I will try to etch with something.On the new diff the driveshaft is cut so I can use an standard puller. To take the old driveshaft off I should appreciate if you could post some picture of your tool. I guess I have to use some heat to get it off??Jan Link to comment Share on other sites More sharing options...
Bhigdog Posted December 25, 2005 Share Posted December 25, 2005 vinegar is a good etchant, I wouldn't go overboard on the heat, no more than 150 deg. C. Link to comment Share on other sites More sharing options...
old-tank Posted December 25, 2005 Share Posted December 25, 2005 Hit the other end of the pin real hard a few times and that should reveal the pin on the other end. Use heat only as a last resort on these parts.Willlie Link to comment Share on other sites More sharing options...
old-tank Posted December 25, 2005 Share Posted December 25, 2005 (edited) These pictures will only be meaningful if you have your parts exposed like Jan.These are 1955 parts, but others should be the same. The puller was made from a spare torque tube. I cut off the flanges at both ends and then cut the front flange in half. The pieces of the front flange fit in the groove at the end of the driveshaft. The puller is set up in the pictures to install the driveshaft, but can be easily set up to pull.As you can see all that is needed in addition to the flanges is is some threaded rod, nuts and washers.I will loan the puller to BCA members on this board.puller1 puller2 puller3puller4Willie Edited January 19, 2011 by old-tank outdated link (see edit history) 1 Link to comment Share on other sites More sharing options...
Guffin Posted December 25, 2005 Author Share Posted December 25, 2005 Isn't the stress taken up by the bearings, or do I misunderstand the function? Is this OK for the bearings. Nice and clear photos, Willies.Another question: How tight should the differential adjusting nut be?Jan Link to comment Share on other sites More sharing options...
old-tank Posted December 25, 2005 Share Posted December 25, 2005 Jan, you are right that forces are directed through the bearings, and although I have never had a problem does not mean that there never will be a problem.The big nut on the pinion is described as a lock nut and although it preloads the bearings it is not an adjusting nut. Torque from 1955 manual calls for 150 ft lbs minimum. The pinion sleeve lock screws are torqued at 35-40 ft lbs and the nuts on the screws are at 12-15 ft lbs. I recheck the torque on the pinion sleeve lock screws after installing the driveshaft on the pinion shaft.Willie Link to comment Share on other sites More sharing options...
Guffin Posted December 26, 2005 Author Share Posted December 26, 2005 I finally managed to get out the pin after drilling part of it out. The pin came out bent so the hole was not straight!? After getting out the pin it was easy to take off the stump of the drive shaft with a puller. I will make a puller similar to your's, Willie, to take off the drive shaft that is now in the car. I think using a puller is the only way to take it off.Thanks for the help.Jan Link to comment Share on other sites More sharing options...
