Re: Torque specs

G'day all, especially Randy, I have been pulling a reasonable number of 55-56 trans apart lately and encountering a lot of stripped threads in the housing to casing area. It is not usually a problem unless it is the bolt (56) or two bolts (55) which are pressurised. I helicoil the failed threads and have no problem attaining the 55-60 lbs, although I opt for the 55 lbs setting on my recently re-calibrated Warren & Brown torque wrench. On the housing bolts I have no problem with the lower Packard factory torque setting as once you install the vertical lower housing attachment bolts, they almost negate any torsional stress on the periphal housing bolts. I appreciate that the factory specs appear to be inconsistent but I have run into trouble before trying to second-guess Packard engineering. I suppose it depends on your faith in Packard engineering.
