Always thought this car had an open rear end until it came apart. Looks like a trac loc. Anybody spot the problem in the pictures? How did something like this come to be?
I don't see a problem, were you having one? When you put one of these together, there is a special tool to set the clutch pack clearance. I borrowed one when I did my trac-loc. Somewhere I made a scaled drawing and put it away for future reference. It must be safe because I can't find it. I don't know what manual I found the special tool in. I just checked a few manuals and the only check they have is after ***embly. You hold one side gear or axle stationary and check the torque to turn the other side gear or axle. With new clutches properly soaked in trac-loc fluid, new clutches should take around 175 ft lb to continuously turn them. With old clutches it drops to a minimum of 75 ft lb.
Yes they did. Maybe that is a Moser or Currie or China copy. When I rebuilt mine I think the clutch pack rebuild kit came with the set tool? Just had a thought; if there are five drive scallops it is a equa-lock predecessor to the Traction-lok which has 4 drive tangs.
It made no noises, just worked like an open rear end. The problem is there are no springs. Clutches look like new since they have never been used. Should be a square block between the spider gears with 4 springs and a plate. This appears to be an open rear carrier half that someone has mated to a trac loc big end half. Is that possible? Can I add the square block and springs to this one or was the other half of the open carrier different than the trac loc?
Yep, I rebuilt my first one, put new clutches and steels in, put it back together. Didn't work, Took it out, checked everything, put it back in. Didn't work, Took it out. Carried the center section into performance transmission place and asked what was wrong. He told me nothing - except I don't know what I'm doing. I paid for him to re***emble it as long as I could watch.
I think what you have is an Equa-lock differential not a Trac-lock. It used a bellville spring/washer to apply pressure to the clutches.
The block in the center isn't the main spring, looks like you are missing the Bellevue spring plus there are 5 drive scallops so it is not a traction loc. If there are five drive scallops it is a equa-lock which is a Ford and predecessor to the Traction-lok which has 4 drive tangs. Rare 4 pinion, most were 2.
That looks like an aftermarket trac loc, OEM Ford carrier has two small countersink screws that hold the halfs together untill the ring gear is installed.
The ring gear half is stamped C6AW 4205-B, and no it doesn't have the 2 screw holes. That's why I'm suspecting it was a regular Ford open that someone slapped on a trac loc big end thinking that would "convert it". But I don't know.
Ford made an early and late traction enhancer that looked similar. Yours could be the earlier one….or not! The earlier ones used larger diameter clutch plates. Yours appears to be “ shiner” than most of the ones I encountered, so it also could be aftermarket , as mentioned! Bones
Great picture. Thanks! Different machining on the face shows me I don't have a standard carrier. So I'm back to not knowing what the hell I have. And why it has a donut between the spiders instead of a square block with springs.
You can buy the "block," springs and spring plate seperate. Is the side gear in good shape? https://shop.broncograveyard.com/Ford-9-Differential-Parts/products/1610/
Side gear looks great. I've found the missing pieces online, I'd just like to be sure they will fit in that housing. I'm thinking now I have an older equa lock housing with an aftermarket trac loc end bolted to it.
