Re: Is there a specific way to weld spider gears?
Yes.....well, in my mind anyway.....and it's pretty cluttered in there so watch your step.
Around here it's called a Fozzy Locker. There are several ways to do a Lincoln Locker, but there are a lot of guys on the island running the Fozzy and I've yet to here about problems with it.
Obviously a proper locker would probably be better, but if your on a budget, this is the way to go. A Fozzy Locker is created by welding the spaces in between the side gears teeth, but leaving a few open on each side of each gear. This allows for a very small amount of movement. In my case the fellow who welded my gears left about an 1/8" of movement in the gears. This translates to a little over 3" of movement at the tire (30" real diameter tire).
I have a couple pictures of the gears after welding, but no scanner. Maybe I'll get a friend to scan them sometime next week. If you do it, make sure you've figured out how to do it right before pulling out the MIG!
This worked great in my Dana30 front on a '77 CJ5, and I'm thinking of doing the rear of my '87 Samurai now. I know several people who run these front and rear on daily driver hardcore rigs without problems.
Like I said, probably better off with a real locker, but I'm too cheap![img]/wwwthreads_images/icons/smile.gif[/img]
The alternatives are:
1) Weld the side gears to the spider gears (quazi mini-spool).
2) Weld the side gears to the spider gears, then to the carrier (quazi full spool).
3) Buy a mini-spool (stronger than the weld, and cheap enough if you can find one for the Dana30)
4) Buy a full-spool (stronger than all above, if you can find one)
Personally I prefer a little bit of movement in the gears. Just don't be gunning it before the gears load up or you might grenade them (although I had to do that a couple times to extract a 5000 lb Landcruiser from a bolder infested river bed, and I "didn't" break anything).
