Open carrier ? Should be easy to find close by . I thought Dr Diff had them but didnt find any on his site.

 

Is it a open differential? I have a few hundred. PM me your address, I’ll mail you one.

 

I swear it was Cass that made a high strength replacment for them .

 

Cone or clutch? Dr Diff sells new spider gears with the shafts for the Dana clutch type. $175.00

 

I got a set maybe, just pay shipping. It was a bare carrier so I dont know what model it came out of.

[FOR SALE] - 8.75 open spider and side gears

 

I believe the OP has a spicer style sure grip unit.

Is the one of the 4 pinion gears that broke? How did you break it?

Please post up a picture of the whole unit but I’m guessing it’s this style.

If its the cross style as above mine may not work. Does anyone know if the spider gears are different between SG's and opens? This is a (broken spider gear) clutch type.

 

Yes. All three, open , cone, clutch type use different spider gears and they do not interchange.

Are the crosspins in ramp to ramp?

 

The ends of the cross pins have a rounded side and a ramped side. The case halves have only a ramped side, the other side being empty. In order for the unit to work, the ramps have to be facing eachother.
When you apply power to the pinion, it turns the case. But with the wheels tied to the road, the sidegears resist the turning. This causes the ramps on the case to ride over the ramps on the crosspins, forcing the spider gears into the side gears, which squeezes the clutches together and thereby clamping the whole thing solid, depending on how the unit is set up.

So, in your pics; it looks to me like the ramps are not oriented correctly, which is why I asked.

In Pishta's post, #11, they appear to be correct

 

The V of the shafts go towards the V in the case halves. One faces down one faces up. Simple enough.
