The old Eaton is ready to go in - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Got her all cleaned up and painted. I rebuilt the carrier with new bearings as the old ones were barrel shaped. Its a 5.14 geared detroit locker unit. The date stamp on the ring gear looks to be 1958. The housing itself is 1960 vintage from a 3/4 ton fleetside which is why theres no spring pads on it. The 1960 it came from had coils too but the trailing arms were spaced about 4 inches wider than my 68's so I had to cut the pads off. I'll bolt it in place with new spring pads and weld them on the tube after I set the pinion angle and center the axle. The Locker works perfectly. I cant wait to try it. 5.14 sounds like a steep gear but it shouldnt be too much with the 32 inch tires. I'll have to try the old tape a hundred to the dash trick.

5:14's, Wow! I guess you won't be driving to North Bend again anytime soon...

looking good I dont think you could break one of those rearends with a sledgehammer, I tried for two years. But they weigh more than any rearend I ever had to move around. Wonder what they weigh. Track opens in a month!

That damned loaded carrier has got to be 180 lbs by itself. The housing doesnt seem to be any worse than a 9 inch ford and the brakes make up the rest . I'd say at least 350 total although it may be a bit more. When I bought it I know two of us lifted it in the back of my truck and that guy was a big Mofo . I had to act like one.

Hey Mike, Let us know how it launches!

CE20934 · 03-22-2003, 07:02 PM

The center section is 140lbs. Exactly.

After it fell on my hand, I was curious. Only 10lbs lighter than my trans. Gotta love cast iron!

mikep · 03-22-2003, 08:19 PM

Just took it for a little trip down the road. Didnt seem all that obnoxious but I only went 40 mph. Little chirping from the tires going into a corner after a stop as you'd expect from a locker. I'll let you know more tomorrow after I hook up the rear brakes. Damned line twisted off at the hose so I have to cut the line and put a new end on it in the morning. I also have to shorten the panhard bar. The dana one was too short and the one from the '60 was a few inches too long .

That sounds awesome, man you sure know your stuff

5.14s demand respect, you better get some smokey burnout pics on here soon

mikep · 03-23-2003, 12:27 AM

I have every intention of doing just that!

UNCLEBOB · 03-23-2003, 01:28 AM

How long does the panhard bar need to be I have one on my corporate axle I took out, its yours if it will work.

mikep · 03-23-2003, 02:34 AM

Thanks UncleBob but I already got mine cut and welded up.

I must say that the dana 60 that came out of my truck was one that I have nerve seen before. Its marked 60-3E on the front and on the bottom and has the panhard bar mount cast into the housing center section....weird.

72chevyLWB · 03-24-2003, 10:53 PM

Hey, you should show us proof of the locker!!!!!!!! Come on you know you want to.

mikep · 03-24-2003, 11:30 PM

I'm kind of babying it until I can find a slightly longer rear driveshaft. Ive got about an inch and a half engagement on the splines at the carrier bearing which is less than I'd like. seems the eaton is a good bit shorter front to rear. the smoke show will have to wait till this weekend when I hit the boneyard for a longer shaft although I did try it out this morning at 5 AM in the work parking lot. the tires were still smoking when I parked it . looked pretty damned cool
