aahhhhhhhhh!!!carrier pin??????????

[mudrat]

ok heres the deal installing 4.56 ring and pinion in my 8.25 all went well until we tried to put the pin in and the ring gear teeth are over the hole where the bar goes through the carrier by about an 1/8th of an inch. i was told by randys ring and pinion that with the factory 3.55's that were in there originally that i would not need a new carrier.has anyone ran into this?it seems like they would have mentioned if it would be a problem. also i have heard of a c-clip eliminator kit but dont know who sells it or if this will even fix the problem

Some people grind a tooth down to get the pin in. Or you can grind one side of the pin, which is what I did.

There's also a special crosspin available with notches cut in it, but the notches weaken it quite a bit. No other carrier is necessary for the 8.25. The best way to go about it is index the ring gear to the carrier so the least amount of gear tooth is in the way, then grind it down.

we thought about grinding down the pin but it looks as if it is chromed or something and worried about the strenght or corrosion.what did you use a angle grinder?

 

[mudrat]

what is the best way grind the pin or grind the teeth?it seems like grinding the teeth would weaken that tooth,but grinding the bar would cause slop.what do you mean by index the ring to the carrier

NONONONO not the pin, the ring gear teeth.
Depending on where you bolt the ring gear to the carrier, relative to the crosspin aka pinion shaft hole, the teeth may be more or less in the way of sliding the pinion shaft out. Bolt it down in a position where the teeth are mostly out of the way and grind the excess off. You have to do it, no big deal.

Diff gears are a sliding-contact gear set. There's never only one tooth in engagement and they slide in and out of mesh, so it's no big deal for one or two teeth to have a small amount missing, especially all the way in @ the toe side of the gear.

thanks jjacobs and xjohnny now i can move forward hopefully at a higher rpm

I've done a combo of both grinding on my 8.8, don't worry about corrosion, it's bathed in oil...
