    Abstract: An adapter (500) includes a first leg, a second leg (522), and a throat portion (526)at least partially define a slot (530) that defines a projection (548) at the closed end (532) of the slot (530) that includes a flat middle portion (554) straddled laterally by a first arcuate portion (556) and a second arcuate portion (558), defining a lateral middle portion width (560). A projection protruding distance (606) is measured along the direction of assembly (536) from the closed end (532) of the slot (530) to the flat middle portion (554). The projection protruding distance (606) ranges from 0.8 to 1.2 multiplied by the lateral middle portion width (560).

    Abstract: Track pad (200) includes a first link member (228) that extends upwardly from the shoe member (208) including a first lug member (230) extending from the first link member (228) in a first direction, as well as a second lug member (232) and a third lug member (234) both extending from the first link member (228) in a second direction opposite of the first direction. The track pad (200) also defines a first side cavity (240) that extends from the first lateral end (216) toward the second lateral end (218), jogging from the front end (220) toward the rear end (222) along the track chain traveling direction (210), and downwardly toward the ground engaging surface (204).

    Abstract: A filter element (200) includes a bottom open end (222) joined to a center tube (206) opposite the top open end (220). The bottom open end (222) defines a radially outer surface (232) and a radially inner surface (234) that is in communication with the central reservoir (204) of the filter element (200). A locking feature (236) is disposed proximate to the bottom open end (222). The locking feature (236) includes an entrance slot (238) that is disposed on the radially inner surface (234) of the center tube (206) extending axially from the bottom open end (222).

    Abstract: A filter element (200) includes a bottom open end (222') joined to a center tube (206, 206') opposite the top open end (220'). The bottom open end (222') defines a radially outer surface (232) and a radially inner surface (234) that is in communication with the central reservoir (204) of the filter element (200). A first locking feature (236') is disposed proximate to the bottom open end (222'). The locking feature (236') includes an entrance slot (238') that is disposed on the radially inner surface (234) of the center tube (206, 206') extending axially from the bottom open end (222'). A similar or identical second locking feature (236'') is disposed proximte to the top open end (220').

    Abstract: In one aspect, an unloaded annular flexible seal (124) is provided for use in a seal assembly (106) configured to receive an end of a conduit (106) and to provide a seal between the conduit and a flange (100) of a machine (1). The seal includes a seal base (154) having an inner surface (158), an upper surface (160), an outer surface (162), and a lower surface (164). The seal also includes a seal leg (156) having an inner surface (170), an upper surface (172) extending from the inner surface of the seal base, an outer surface (166) extending from the lower surface of the seal base, and a lower surface (168). A surface area of the outer surface of the seal leg is greater than a surface area of the lower surface of the seal leg.

    Abstract: A sealed and lubricated rotatable track engaging element (130) includes a roller (32) and a roller shaft (38) extending through the roller (32) to support the roller (32) for rotation about a major axis (36). A first thrust surface (46) is fixed relative to the roller (32), and a second thrust surface (48) is fixed relative to the roller shaft (38). A seal cavity (44) extends between the roller (32) and the roller shaft (38) and is formed in part by each of the first thrust surface (46) and the second thrust surface (48), and a thrust washer stack (50) is within the seal cavity (44) and trapped between the first thrust surface (46) and the second thrust surface (48). The thrust washer stack (50) includes an inner thrust washer contacting the roller (32) to rotate at a first fractional speed of a speed of rotation of the roller (32), and an outer thrust washer contacting the inner thrust washer and the collar (68) to rotate at a second fractional speed that is less than the first fractional speed.

    Abstract: A retainer sleeve (70) for use with a lock (60) in a ground engaging tool (10). The retainer sleeve may include an outer skirt (73) extending around a retainer axis (75), where the outer skirt may include an outer surface (76) formed to mate with a lock cavity (43) of the ground engaging tool. The retainer sleeve can further include an inner skirt (74) flexibly connected to the outer skirt via a lower bend (71). The inner skirt may be formed to rotatably receive an outer surface (66) of the lock. The retainer sleeve may also include a detent projection (77) extending radially inward from the inner skirt with respect to the retainer axis and formed to engage a detent recess (67) of the lock to releasably hold the lock.
