How does this pattern look

Pinion depth is a little deep. Pull out .005" and recheck.

Pinion too deep. Are you loading the ring gear when you take a reading? Much easier to spin the pinion with a drill (not an impact, they vibrate to much) while holding load on the ring gear.

No didn’t load the pinion. Turning it by hand. I’ll try that when I get home. Thanks

I just jam a large screwdriver between the case and ring gear (pointing in direction of rotation). I use a ratchet and socket to turn. Just start turning so to spin through the painted teeth.

Ok this looks a little better with a load and using a socket and ratchet.

It’s a tad too deep, but otherwise I’d run it.

It’s to far down the tooth for me. What’s the backlash? Opening the BL should center it more top to bottom of the tooth (not toe to heel). Heel to toe doesn’t look horrible, I like’m a tad deep. The pinion will try to walk out of the gear under load.

 

[74charger07ram]

Backlash is at.007

 

[5.7 hemi]

That’s in the range I try for..... .007-.010.

 

[74charger07ram]

So should I try to go to .008-.009 backlash? Or should I put a thinner shim? I used the original shim that was .070. That would mean taking it all apart including the pinion.

 

[5.7 hemi]

Move the ring away from the pinion, try .005 and check pattern again. If acceptable, check the backlash. If it’s still in range, lock it down and run it.

 

[74charger07ram]

So you're saying to put a .065 shim between the rear pinion bearing cone and the case? Then put it all back together? I would then have to set the backlash and then check the pattern.

 

[5.7 hemi]

No.

This is an 8.25 so I’m not sure if the carrier bearings can be adjusted like an 8.75. I’m guessing not. So I’d take .005 from the drivers side bearing and move it to the passenger side and recheck it.

 

[74charger07ram]

To set pinion depth you change the shim out that is between the outer pinion bearning and the case. The shims range from .061 to .079. Don't know what you mean taking .005 from the drivers side bearing. If you move the whole chunck over .005 you are changing the backlash which should be between .006-.008. There are no shins on the left or right side to change out.

 

[5.7 hemi]

Are there adjusters?

 

[74charger07ram]

Yes, one on the left one on the right. They are threaded. As you turn one it moves the ring gear left or right to get the backlash. Once you get the backlash torque it 70 ft lbs

 

[5.7 hemi]

Ok, loosen one side and tighten the other and check it.

 

[74charger07ram]

Ok I’ll do that when I get home thanks

8.25 is a "in housing" not a "drop out". Pretty much the same thing though with the adjustments. Does yours have the crush sleeve?

Don't know what changes might have been made after this video. (1969)
