Further, the example system determines a sparse stereo disparity (760) between the left- edge digital image and the right-edge digital image, determines measurement data related to the GET and also determines a wear level or loss for the at least one GET based on the measurement data.

A ratio of the cavity diameter (D302) to the first threaded hole diameter (D304) ranges from 8.0 to 8.15.
A retainer (900) includes a drive portion (902) defining a drive portion outer diameter, and a lug receiving portion with a skirt (904) defining a lug receiving slot (914) that extends partially through the lug receiving portion, forming a first sidewall, a second sidewall, and a catch surface connecting the first sidewall to the second sidewall. The skirt (904) also defines a skirt outer diameter that is greater than the drive portion outer diameter. Also, the drive portion (902) has a hook tab (908) that extends from the drive portion (902) and that is spaced away from the skirt (904) a minimum distance.
A shroud (62) for a track shoe grouser protector (36) includes an elongate shroud body (92) having weld holes (108) formed in a first shroud leg (72) and a second shroud leg (74) attached to a base (70) in the elongate shroud body (92). The shroud (62) may have a fore to aft profile having the form of a flat-crowned arch with the shroud legs (72,74) flared outward to form a grouser opening (76) for positioning the shroud (62) upon a track shoe grouser (30) in a ground-engaging track system (14). An inventory of shrouds (100) includes long shrouds (62) and short shrouds (62,462) positionable in a plurality of different assembly combinations to shield grousers (30) in track shoes (26) having a range of sizes.
A valve for controlling a hydraulic cylinder on a work machine may include a raising position configured for placing a pump in fluid communication with a cap end of the hydraulic cylinder. The valve may also include closed center position configured for closing off fluid communication to the cap end line and the rod end line. The valve may also include a lowering position configured for placing the pump in fluid communication with the rod end of the hydraulic cylinder. The valve may also include a snubbing position configured for placing the cap end in restricted flow fluid communication with the tank and for placing the rod end in restricted flow fluid communication with the tank.

A wear part removal system (200) includes a handle (204), a positioning system (218) configured to control an approach angle (402, 406) of the wear part removal system (200) to a wear part (104), a clamping system (210) that includes a plurality of clamps (212) and that is configured to clamp the wear part (104), a contact component (216) configured to contact a portion of the wear part (104), and a vibrator device (214) configured to generate a vibratory force that is to be transmitted to the wear part (104).
An onboard track machine wear measurement system (300) has an ultra-sonic probe (302) that is attached to an undercarriage (114) of the machine (100) that is disposed adjacent a track chain assembly (126), and a controller (304) that is in communication with the ultra-sonic probe (302). The controller (304) is configured to determine the thickness of a load bearing wall of a track component (200) of the track chain assembly (126).
A track chain assembly (126) includes a first track pad (200, 200a) including a first pair of lugs (232, 234) defining a gap (236) therebetween, and a second track pad (200, 200a) including an intermediate lug (230) disposed in the gap (236). The first pair of lugs (232, 234) and the intermediate lug (230) each define a concentric bore (206, 206a), defining an axis of rotation (132) for a pinned joint (138) of the track chain assembly (126), and the concentric bore (206, 206a) of one of the first pair of lugs (232, 234) is in communication with the gap (236) with a first blend (238) disposed axially between the gap (236) and the concentric bore.
