\'Fozzy\' lockers and 4 X-Gears in the differential.

I've researched the 'Fozzy' locker thing. This trick involves running two weld beads, 180 degrees apart on the differential side gears. This allows each of the side gears to rotate '100 and some degrees' relative to each other before it 'locks'. This play allows the differential to remain open on large radius turns, and improves driveability as compared to a welded diff or spool. It also allows the front hubs to be locked and unlocked without binding, according to what I read. It sounds cool! Except it won't work well with four X-gears, like the older Samurai, will it? If you have two X-gears, like the newer Sammy or a Heep, you get the full 100 plus degrees before the lock-up. With four X-gears, you'd get half or less than half as much differential action before the welds on the side gears hit the X-gears. Does this sound right?

Re: \'Fozzy\' lockers and 4 X-Gears in the differential.

On 02/20/2004 there's a post about a soft-welded Samurai differential that uses four weld beads on the side gear instead of welding the side gears to the X-gears. This is not actually a 'Fozzy' locker. It does not look like you turn a 4 X-gear differential into a 'Fozzy' at all. Is this right? When I say X-gears, I mean spider gears.

Lead the stock Samurai carrier. It allows for a little bit more play than a spool or welding it and if you don't like it you can heat up the lead and pour it back out of the carrier. It does take a little bit of use for the rear to loosen up.

Re: \'Fozzy\' lockers and 4 X-Gears in the differential.

That's the post I'm talking about...thanx for bringing it forward...I don't know how to do that...This article is title "Welded Differential for the Sammy". It is not a Fozzy at all, there is no differential action left over in this set-up. It's a non-rigid weld, so you have a little play in the axles to lock/unlock the hubs. A Fozzy is done with two spider gears and two weld beads on each side gear. Imagine the spider gears at 12 o'clock and 6 o'clock, the welds would be at 3 o'clock and 9 o'clock. You could leave one tire on the ground, and rotate the opposite tire almost 1/2 of a turn before the spiders hit the weld. When you drive the <nobr><nobr><a class="iAs" style="border-bottom:darkgreen 1px solid;text-decoration:underline;color:darkgreen;background-color:transparent;" href="#" onclick="return kwC();" target="_blank" oncontextmenu="return false;" onmouseover="kwE(event,217917);" onmouseout="kwL(event);" onmousemove="kwM(217917);">vehicle</nobr></a></nobr>, this slack allows for differential action, it allows one tire to move faster than the other one, like an open differential, until the radius of the turn your making in the vehicle is tight enough that the spiders hit the welds. I don't have any idea of how tight this radius would be. If a tire breaks traction, the Fozzy locks up after the tire slips 1/2 a turn relative to the other tire. The Fozzy seems like a really cool idea, but I don't know how they function in real life. They may clunk really bad. And it only works with two spider gears, not four.

Re: \'Fozzy\' lockers and 4 X-Gears in the differential.

Sorry if that didn't help you. I'm pretty sure that this is what's reffered to as a Fozzy because the gears aren't welded solid and there is a small amount of movement allowed, the only difference being the four side gears as opposed to only two in other applications.
FWIW, this site was sent to me as a link marked as a "Fozzy Locker" several months ago.
