5、ised 2010-05Reaffirmed 2016-05 Superseding J371 MY2010 Drain, Fill, and Level Plugs for Off-Road, Self-Propelled Work Machines RATIONALE J371 has been reaffirmed to comply with the SAE five-year review policy. FOREWORD Plugs are extensively used in off-road, self-propelled work machines as defined i

6、n SAE J1116. Loss of these plugs, stripping of the threads, or failure to tighten because of difficulty in finding the right tool can result in serious damage and/or increased down time. All the plugs listed are nominal inch sizes pending the development of metric plug standards. 1. SCOPE This SAE R

7、ecommended Practice applies to off-road, self-propelled work machine categories of earthmoving, forestry, road building and maintenance, and specialized mining machinery as defined in SAE J1116., 1.1 Purpose The purpose of this document is to standardize and, therefore, minimize the number of sizes

8、and types of drain, fill, and level plugs required. It also establishes types and sizes of pipe thread and straight thread plugs requiring commercially available hand tools for removal and installation. It is not intended to establish dimensions and materials. 2. REFERENCES 2.1 Applicable Publicatio
