I just got the rear third welded together for my FJ60. Basically my issue is that the spider gears are slightly off from each other. We tack welded everything together with the pinion pin installed. Then removed the pinon pin and finished. Now it takes a hammer to get the pin all the way in. This could be an issue to remove the c clip and get the axles out later.

My question is this: would there be any problem with sanding down one side only where it goes into the other spider less than a 1/16" to make it drop in?

Thanks for help!:bounce2:
 
If you can get the cross pin in with a hammer, I would leave it like that. Also, if you can get it in, you probably don't need to take off that much material. If you are going to remove material, do it on the spider gears themselves, using a dremel tool or die grinder with a sanding drum, and remove only the minimum amount.
 


why do people weld up the whole set of spiders ?

i know lots of guys who only weld 1 tooth shut on all the spiders to make it give just a little on assembly . plus if thay want thay can go back to open or lunchbox locker later.

also seems much faster to do in the end with 1 tooth spot welded up on all the gears so thay cant rotate all the way only a tiny bit.

You have been reading petersons 4wd.

I'm sure that would work too. But it would also weaken the spiders a that much heat in one spot on heat treated 8620 gear material, I believe would cause stress cracks when it cools. Theres also the binding of the spiders trying to rotate a little then riding up on a gear valley full of weld. Seems like it would pus added stress on the carrier in a place it was not designed to have stress.
 
Back to the thread....
 
Go all or nothing on the weld in my opinion. Don't want a weld to break and #%$# something else up. If I want to go back to being open I will get another third or drive a car.:fuck-you:

After a restless night, a dremel on the spider was what what I woke up with in my head. I can see just enough play to have the axle fall out if I grind on the pinion shaft! Clearance very close on the spider. I don't thing it will take much plus a hammer. Thanks for the confirmation.
 
i dont read those mags anymore.

i go web readin :popcorn: more fun
 
If I welded another Cruiser rear I would disassemble everything clean the spiders good and then spray anti splatter on the axle shafts, pinion shaft and spacer. Then reassemble and tack the spider gears in a few spots. Then let them cool completely, dissassemble again and finish weld.
