Claim 1:
2. The torque tool apparatus of claim 1, wherein the torque head assembly comprises:
two matching torque force plates, each having a matching first plurality of force plate bores at one end and a matching second plurality of force plate bores at the other end; and
a torque plate having a first end with a first plurality of torque plate bores aligned with the first plurality of force plate bores, and a second end defined by a frustoconical-ovoid-shaped aperture having a flat narrow end, a pair of opposed outward-extending sides, an ovoid rib conjoining the pair of outward-extending sides, and a reinforcing collar at a midpoint of the ovoid rib, the reinforcing collar provided with a threaded bore in communication with the frustoconical-ovoid-shaped aperture; and
a bolt for threadable engagement with the threaded bore in the reinforcing collar;
whereby the torque plate is demountably engageable between the two torque force plates by aligning the first plurality of bores, inserting at least two bolts therethrough and threadably engaging two nuts therewith;
wherein the torque head assembly is demountable engageable with the torque tool hydraulic cylinder aligning a rod eye of the torque tool hydraulic cylinder with a selected pair of second bores and inserting a clevis pin therethrough;
whereby a hexagonal hydraulic cylinder piston-retaining nut of a hydraulic cylinder in need of service, is demountably engageable with the torque head assembly by positioning two sides of the hexagonal piston-retaining nut between the pair of outward-extending sides of the frustoconical-ovoid-shaped aperture and threadably engaging the bolt with a third side of the hexagonal piston-retaining nut.
