Need Case Stretcher
Does anyone have a case stretcher that I can borrow or know where I can rent one?
I may have a carrier bearing going bad but cannot get the unit out of the housing to check. Most tool rental houses think I'm from Mars when I ask if they have one, even NAPA didn't have a clue. I may have to build one if I can't find one. Thanks Jeff |
Excuse my ignorance, but what is a case stretcher?

More info...IRS? 9" live axle?
I am also stumped…I receive many email offers to enlarge certain parts, but a "case" is new to me Call Rusty Bayh. (cell: 214.914.9342) He sets up all of the road racing rear ends and Toploaders used in vintage and high horsepower applications. If he doesn't pick up, leave a message. He is an engineer professionally. He might be willing to do a ride-along to help diagnose. Tell him hello for me. Paul May McKinney space |
Well a case stretcher was new to me also. Many of the housings have an interferrence fit between the housing bearing retainer and the carrier. In some housings, the "interferrence" is greater (tighter) than others. Of course, mine being the case!
As for the ride along? Too late, the car is on jack stands, engine and transmission out for a new clutch, drained the housing, axels out and removed the cover and bearing caps. Just cannot get the carrier out! Thanks for the name and contact info, I may need to call for his help if I cannot locate/build the stretcher. Thanks again. |
I would say that you need a little heat in there to get the bearing out. Stretcher?....backyard mechanics??%/

There is such a thing as a case stretcher. I recalled seeing one in my Ford service manual for my '77 F150. In the picture, it's being used on a Dana 44 front axle. It looks like a simple tool that would be easy to make. It's basically a couple of upright bars that fasten to the axle housing, with a crossbar on the top and a turnbuckle on the bottom. The Ford part number is Tool-4000-D. Check with your local Ford dealer. They might be able to help.

Thanks Tom, will do.
Just in case, I bought some angle iron and some bolts. Most of the other items I already have. If FOMOCO doesn't or won't help, I'm in the fab business. I can always take the steel and bolts back. Thanks again. Jeff |
Using a case strecher is the proper way to get the carrier in and out and to preload on the carrier bearings. Probably been 35 years since I used one while working at a Ford dealership. Should be able to pull up procedure on line... Fairly simple in design and to build, but needs to be pretty stout.
