A method of repairing a chain can include aligning a bore of an outer chain link with a bore of an inner chain link, inserting a pin through the aligned bores, the pin having a thread end opposite a head end, engaging a multi-jackbolt tensioner with the thread end of the pin, the multi-jackbolt tensioner having a plurality of fasteners, advancing each of the plurality of fasteners to press on the outer chain link, and forming an interference fit between the pin and the outer chain link at the bore of the outer chain link from the advancing of the fasteners.

A wedge driver and method therefor is presented. A wedge driver can be operably coupled to different ends of a link joiner to drive a wedge therebetween to form a single link. The wedge driver can also drive the wedge out of the link joiner. The present disclosure provides the benefit of allowing the safe and effective removal of the link joiner by preventing violent or forceful decoupling of a link joiner. The wedge driver can include a trunk, a first prong, a second prong, a bolt, and a driver. The driver can be spring enabled, such that the driver can recede into the trunk as the bolt egresses the trunk. A bolt of the wedge driver can push a driver out of the trunk to axially drive the wedge into (or out of) a link joiner without rotating the wedge.

Described herein are examples of chain pullers, which may include a first arm, a second arm, a first linkage, a second linkage, and an actuator. The first arm may include a linkage end and an engagement end. The second arm may include a linkage end and an engagement end. The first linkage may include a proximal end connected to the first arm and a distal end connected to the second arm. The second linkage may include a proximal end connected to the first arm and a distal end connected to the second arm. The actuator may have a first end connected to the first arm and a second end connected to the second arm. The first arm, the second arm, the first linkage, the second linkage, and the actuator may be configured such that when the actuator is actuated, a distance between the engagement ends is changed.
