stepdown driveshaft repair

Unknown

I replaced my transmission mount this weekend and decided to replace the center driveshaft mounts and carrier bearing. I have removed the driveshaft(s) and center support (carrier) bearing from my stepdown all in one piece. (I thought I had seen a post regarding this previously, but couldn't find it through the seach tool.)



Can someone tell me how to seperate them and remove the carrier bearing? Also, is 88506 the correct Napa part number for that bearing? Any help you can give me would be appreciated.



Thanks, Terry

Terry, have you been to Ken Cates' fine Hudson StepDown webpage at http://members.aol.com/stepdown53/STEPDOWNPG.html .



I do NOT know if he would answer your question there, and with any luck someone will place an answer on this thread soon. But in the meantime, if you have not been to Ken's site, you just might find your answer there.

Here are the part numbers for the bearings.



'48-'52 All Exc Pacemaker and Wasp use #88506



'50-'52 Pacemaker and Wasp use #88107



'53-'54 All Exc Jet use #88107



I am not totally sure about the above infomation. So here are the dimensions of the bearings. You can measure yours and pick the right one.



#88506

ID 1.1811 inchs

OD 2.4409

Width 0.9449 inchs



#88107

ID 1.3780 inchs

OD 2.8346

Width 0.9843 inchs

Terry, The main thing to pay attention to is the orientation of the front half of the driveshaft to the rear half of the shaft. It must go back in the same orientation (or Phase) if not, it will vibrate badly. Mark it somehow before you disassemble it.
The rear half of the driveshaft will slide off the splines of the front half, behind the carrier bearing, then there is, I believe, and I may be wrong about this as it has been several years since I replaced mine, a locking collar on the bearing. Loosen the collar and the front shaft should slide out. Pay attention to which side the collar is on, Front or Rear of the bearing. I hope this helps.

Remove the sliding sleeve nut just behind the bearing which will allow the bearing to be removed. There is a snap ring on both sides of the bearing. Remove these and it can be pressed off.

Terry, to remove the bearing, first remove the one bolt that holds the cast iron bearing housing to the stamped steel bracket that's supported by the rubber cushions. Then you can work with the bearing housing a bit easier. You have to remove a snap ring that holds the bearing in place, then press the bearing out of the casting. If you don't have access to a press, you may be able to tap the bearing out, taking care to avoid cocking it in the housing. For such purposes I keep a collection of short lengths of iron pipe, in various diameters.

Jon, Mars55, Bob, thanks for the response and information. The two pieces would not separate last night, but I didn't get aggressive with it either. Thought I would ask first. I thought the back half should slide off the splines but wasn't sure. I will try to "encourage" it to come apart tonight.



I have looked at, and used Ken's website info more than I care to think about lately, but didn't see anything about the driveshaft, other than the tip on the carrier bearing.



The driveshaft has been modified (different engine) in the past and is well marked for re-alignment. (I've already been down that road.)



Thanks again,

Terry

I know, if I just would have had you installed those vent windows last week I wouldn't have started this project! I'll probably be draggin' this driveline over to you too.



Uncle Josh, Park W... thanks for the info.

With a little "encouraging" I was able to separate the two pieces, and removed the carrier support unit.



Thanks everyone, for your advice.

resurrecting this thread from the dead......

I just took my '50 Club coupe out for a test drive after swapping the motor and overhauling the tranny.....I'm getting a noticeable vibration when I hit about 30-40mph.  I was assuming it was worn u-joints but I saw this thread and it mentioned the two shafts are phased together.  Well, when I removed my front shaft I had just dropped it without marking anything, is there a way to determine that it is 'in-phase' before I start ordering parts that I may not need?  Are there any markings on the shafts?

Lol...yup, that'll do it! I'll make sure they are all in alignment from front to back. Thanks Ken!
