SystemOne? WORN LINK BOXES
With the introduction of SystemOne? it may be necessary to replace a link box before the entire link assembly has reached its 100% total wear life. The following tables provide you options on which link box you should use to best match the wear on the link assembly. By selecting the correct link box, it will help maintain the benefit of a smooth ride and fine grading capabilities. It is recommended that if the link assembly is greater than 40% worn, then you should replaced with a 70% worn link box.
