If it takes a 1/2-inch wrench to remove it, it’s an 8.2. (e in b)&&0
The 8.2-inch 10-bolt has a smooth, round, lower-case area (no cast-in protrusions), with an 11-inch cover that has a diagonal protrusion at the top.
If it takes a 5/16-inch wrench to remove it, it’s an 8.5. This is done to allow a safety buffer so that the bolt does not get too close to the proofload value. Low Profile, LoaDisc ? HYTORC offers the latest hydraulic bolting technology with unique patented benefits that provide industry-leading safety and accuracy. * SAE J429 grade 8 bolts do not exceed 1-1/2″ diameter. HYTORC Sales & Service . 38 Values calculated using industry accepted formula T = KDP where T = Torque, K = torque coefficient (dimensionless), D = nominal diameter (inches), P = bolt clamp load, lb. Follow along as our employee Zach installs a GM 10 bolt rebuild kit from Motive Gear. 150 46 pressure wax as supplied on high strength nuts) = .10, hot dip galvanized = .25, and plain non-plated bolts (as received) = .20. 58 Moly / lead oxide / graphite 16 30 There is a difference, but you can’t see it unless you set both units on their side, and then measure the distance from that surface to the face where the ring gear attaches.
But, did you know there is more than one style of 10-bolt rearend? Although the 7.5-inch 10-bolt closely resembles the 8.5-inch housing, you can positively identify the Chevy 7.5-inch rearend by measuring it. 20 8 Inside, the ring-gear bolts are the same as the 8.5 corporate unit, but the pinion-shaft diameter measures 1.438 inches.

There were an untold number of 8.2-inch axle assemblies built, and although it is only marginally stronger than the 7.5-inch rearend, it does have some aftermarket support. Instead of using a C-clip to hold the axle in the housing, these axle assemblies use bolt-in axles, much like an 8.2 BOP rearend. Inside the 8.2-inch 10-bolt, the ring-gear bolts have 9/16-inch socket heads with 3/8-24 left-hand threads.

54 6 to 7 in-lbs. These protrusions are larger than those on the 7.5 rearend. 60 ft-lbs. There are several differentials for the 10-bolt rearend. With the exception of truck differentials with 30-spline axles, and those carrying 2.41 and 2.73 gears (series two), the differentials will support all gear ratios without having to change carriers. 14 The distance between the lower center bolt on the cover and either adjacent bolt is 3 3/4 inches. The 8.5-inch 10-bolt also shares the same pinion shaft diameter as the more expensive 12-bolt.
600 900 Randy Bolig has been working on cars and has been involved in the hobby ever since he bought his first car when he was only 14 years old. 26 10 Most 8.2 factory covers also have the strange protrusion at the top. The easiest way to tell the difference is by looking at the brakes. These have been around since 1975, and were installed under cars, small trucks, and vans up to the 2005 model year.
Torque calculations are based on the simplified formula explained in the current version of ASME PCC-1, Appendix K. As gasket load requirements for standard flanges generally fall within the mid-range of the bolt loads, gasket stress has not been used to calculate torque values. The bolt is stressed up to the proofload value, and if there is no deformation, elongation, or fracture, then the bolt is deemed to have passed. The below estimated torque calculations are only offered as a guide. Like most 10-bolts, the axles are held in place by C-clips on the inner end of the axles. This is an 8.2 BOP axle. ANSI B16.5
The program will work in standard U.S. customary units (inch) or SI (metric) units. However, the gears will not interchange with a Chevy 8.2. 60 ft-lbs. There is an anomaly to the “corporate” 8.5-inch axle assembly that was used in some 1971 and 1972 Buick, Oldsmobile, a few 1969 through 1972 Pontiac vehicles, as well as the 1970 through 1972 Monte Carlo. No, Lubricant ? .
