A master link for a track chain is disclosed. The master link may include a first portion that abuts a first face of the link, a second portion that abuts a second face of the link, a first bore located on a first end of the link, a second bore located on a second end of the link, and a material located between the first portion and the second portion and extending between the first bore and the second bore. The material may create a separation between the first portion and the second portion to facilitate placement of the first bore and the second bore around outer diameters of corresponding mating members of a track chain. The material may be removable to remove the separation from between the first portion and the second portion.

Provided is a crawler pad with improved durability for preventing foreign materials from coming through between crawler pads, greatly improving the strength of steel cores and improving the integrity of a pad body and a steel core. In the prior one, the typical crawler pad had a problem that its life time keeps shortened because foreign materials such as sands, etc. penetrate through into the space between neighboring crawler pads, and the rubber-made pad body was damaged. Foreign material prevention stops are formed on with protruded from the front and back surfaces of the ground contact part, and function to firstly prevent foreign material from coming into space between two neighboring pad bodies, and overlap inclines are formed on the front and the back lower surfaces of the pad body respectively with inclined downwards so as to be overlapped with those of neighboring another pad body and thereby to form an overlap region and secondly prevent foreign material from coming into.

A method of servicing a track chain assembly includes loosening a fastener to reduce a clamping force of a track link body on a track bushing. With the clamping force reduced, the method includes rotating the track bushing from a first position wherein a worn side of the track bushing faces a drive sprocket to a second position wherein an unworn side of the track bushing faces the drive sprocket. Once the track bushing in the second position, the method includes tightening the fastener to increase the clamping force on the track bushing. The method can be performed while leaving the track chain in place on a track machine.
