Rear End Flange Nut and Cotter Pin

[Conn47D24]

A little help ( again ) please all.

 

 

I rebuilt the rear axel this winter.  Bearings, seals, etc.  All set to install on new springs, and forgot I never finished one thing.

 

The Nut on the Flange needs a cotter pin.  However this nut and pin are set in the reccess of the flange.

 

1. How tight do I set this nut?

 

2. HOW DO I GET A COTTER PIN IN THERE?

 

Thanks in advance.

One of my books shows the "Rear axle drive pinion flange nut" as being torqued to 180 minimum.

 

I slightly bent a cotter pin so that it was in a curve and was able to feed it into the hole on the shaft. At least that is what I remember but it has been a lot of years since I did it.

Shop manual calls for " pre-loading" the bearing.  Show a special tool and gauge which I wouldn't know how to use if I had it.

 

 

I'll work on the cotter pin idea though !

I pre-curve the cotter pins...and install them once the nut has been torqued to at least a minimum of 180 foot lbs.

I use a service tool to hold the companion flange to make these kind of jobs easy. Shown is the tool on a M-5 transmission flange.

That reminded my how I torqued that nut: I had some scrap 5/16" or so thick steel bar which I drilled some holes to match a couple of the bolt holes on the flange and used it to hold the flange in place while I torqued the nut. I needed something to keep the flange from turning when I couldn't use the brakes, etc. to hold thing still.

 

 I hadn't seen that factory tool but the temporary tool I made looked close enough to what you show to trigger that old memory.

Another pic of the service tool at the diff pinion flange to give ideas for fabbing up as mentioned...

The other end of that tool looks like it has a specific purpose as well. It's used for ???

thanks.  Tool gets used for nuts on both ends of the driveshaft.
