A repair axial bearing system includes an arcuate rail coupled to a support, one or more bolts protruding upward from a raised portion coupled to a supported member, and a lever plate including at least one low friction bearing pad mounted in the lever plate. A first new bearing surface is formed on the arcuate rail. A second new bearing surface is formed on the at least one low friction bearing pad. The one or more bolts are tensioned with bolt tensioners to press the lever plate against the raised portion. The axial bearing system can include a hydraulic cylinder to slide the second bearing surface over the first bearing surface. The repair axial bearing system can be used to supplant a damaged axial bearing positioned between an FPSO and a turret.

An engine piston wrist pin installation tool, kit and method provide the ability to install a piston in an engine block while the corresponding piston rod is assembled to the crankshaft. The wrist pin aperture is first aligned with an access hole provided on the engine block, which may be performed by using a tapered alignment tool provided in the tool kit. A mounting flange configured for bolting to preformed holes in the engine block is first attached over the access hole, the alignment performed, and a tool including a cylindrical sheath that holds a wrist pin clip compressed and a rod that holds the wrist pin and clip is slid through a locking collar of the flange and secured in place. The rod is then pressed through the sheath to extend the wrist pin and wrist pin clip into the piston until the wrist pin clip snaps into place.

A bearing assembly includes a support ring, a plurality of bearing-element carrier members coupled to the support ring, and a plurality of superhard bearing elements having a lateral periphery extending between a base and a superhard bearing surface. At least one superhard bearing element of the plurality of superhard bearing elements is attached to each of the plurality of bearing-element carrier members. A bearing apparatus includes a rotor, a stator, and a bearing assembly. A method for assembling a bearing assembly includes attaching at least one superhard bearing element to each of a plurality of bearing-element carrier members and coupling the plurality of bearing-element carrier members to a support ring.

The tool is designed to carried out maintenance operations on a bearing assembly comprising a bushing split into at least two shells; the maintenance tool comprises a device arranged to act on and rotate the bushing shells. In particular, the device comprises a slide and a pin; the slide has a hole transversal to its sliding direction and the pin is slidably mounted inside the hole and protrudes from the hole; in a first operating position the pin acts on a shell and in a second operating position the pin does not act on any shell. The method provides to rotate the bushing shells without rotating the supported shaft, and to carry out maintenance operations on a shell at a time while leaving the shaft supported by the other shell.

An oil filter adapter provides lubrication delivery for lubricating an engine bearing provides high reliability through an externally-supplied lubrication. The oil filter adapter may be supplied as part of a kit including a lubrication delivery tube for supplying the external lubrication to a mounting flange of the bearing.

A bearing assembly is disclosed having a wearing surface formed from an alloying including tin, a wear material configured to be contacted by the wearing material during use, and the wear material having a smoothed surface. A method of providing superlubricious performance of a bearing assembly is also provided.
