API SA Greases There are several differentials for the 10-bolt rearend. The program will work in standard U.S. customary units (inch) or SI (metric) units. That’s usually proven when used in high-performance, high-horsepower applications. Nickel and Graphite The user must have all suggested values checked by a qualified engineer for accuracy and applicability prior to implementation.
RECOMMENDED ASSEMBLY TORQUES Class 10.9 ISO Metric Coarse Pitch Bolts & Screws Bolt Tension Recommended Corresponding to Assembly 65% of Proof Load Torque kN Nm 7.67 8 10.9 13 19.8 32 31.3 63 45.5 109 62.1 174 84.5 270 103 371 132 528 164 722 190 914 248 1339 303 1817 To convert kN to lbf: Multiply kN by 224.809 To convert Nm to lbft: Multiply Nm by 0.737562 371 2449 441 31173 … Two 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. We'll send you the most interesting Chevy Hardcore articles, news, car features, and videos every week. 0.75 1.5 The below estimated torque calculations are only offered as a guide. 30 Rightfully so, because when comparing the 10 and 12-bolt units, it’s definitely the more durable of the two. HYTORC LoaDisc® & TS 801 Spray 36 Compare These Parts Talk to the Experts. The control arm-mounting ears on top of this 7.5 rearend denotes it is usable for any 1978-’88 GM A or G-body intermediate like a Cutlass, Monte Carlo, El Camino, Malibu, Regal, or Grand Prix. No, Lubricant ? Originally, gear ratios ranged from 2.41 through 4.10. That way, you don’t unknowingly spend money on something you really do not want. 0.5 Portland Bolt provides anchor bolts and nonstandard construction HYTORC Bolt Patterns Four Machine. This is done to allow a safety buffer so that the bolt does not get too close to the proofload value. ":"&")+"url="+encodeURIComponent(b)),f.setRequestHeader("Content-Type","application/x-www-form-urlencoded"),f.send(a))}}}function B(){var b={},c;c=document.getElementsByTagName("IMG");if(!c.length)return{};var a=c[0];if(! Chat Products to Compare (max of 3) X. 3 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. But, did you know there is more than one style of 10-bolt rearend? Ford 8" (Drop Out) 12 to 14 in-lbs. While the 10-bolt rearend’s lineage can be identified by the code stamps, which are usually on the passenger’s side axle tube, there are literally hundreds of potential codes for the three different 10-bolt rearend housings. For bolting specifications that do not have a published proofload, it is usually calculated at 92% of minimum yield strength.
We will safeguard your e-mail and only send content you request. A bolt pattern is arrangement of bolted joints, typically four or more, that connect two or more components together. Help is just a click away! 10 (function(){for(var g="function"==typeof Object.defineProperties?Object.defineProperty:function(b,c,a){if(a.get||a.set)throw new TypeError("ES3 does not support getters and setters. The 8.5-inch 10-bolt rearend was used in cars and trucks over a wide range of years. Please use the data from the program as a guideline only* This program will not produce appropriate results if you are dealing with non-standard flanges, or metal-to-metal machine or structural joints or where extreme temperatures or other unusual operating conditions or materials are being used. Due to many variables that affect the torque-tension relationship like human error, surface texture, and lubrication the only way to determine the correct torque is through experimentation under actual joint and assembly conditions.
