To determine wear limits, Premier created Wear Gages that help judge the useful life of couplings /pintle hitches and drawbar eyes. Available as a complete kit or individually, these gages are easy to use and are a must for Maintenance Managers and safety personnel.
In accordance with Premier and the Federal Motor Carrier Safety Regulations, these were designed to identify wear at the critical percentages of 18% and 20%, by measuring the cross-section of coupling hooks (horn) and drawbar eye loops. 18% wear indicates that the product should be replaced as soon as possible. At 20% wear, the product is no longer in usable condition and must be taken out of service immediately, and replaced.
The latch gage bar measures the gap space between the top of the coupling hook and the closed latch. If the 3/8” latch gage bar can pass between this region, then the latch components should be considered worn past safe limits and replaced.Please note that these wear gage specifications are in accordance with Premier Mfg. Co. and the Federal Motor Carrier Safety Regulations (refer to other manufacturer’s specifications for wear limits on their products).
