Throttle Valve Handle is the Tamco/Toku service part carried under part number 430126A50. It is part of the operator control on the rock drill. Because it is handled every cycle of every shift, wear here is felt as a vague or sticky trigger long before the machine stops.
The published breakdown lists it on the TJ 20 Rock Drill (RD 40). The tool itself is the Tamco/Toku TJ-20 Rock Drill. Worth matching the reference number on the diagram against your own machine before you order the same part number can sit in more than one position.
The rest of the assembly is on the same breakdown, and every diagram we publish is indexed on the parts diagram library. It ships out of Denver, same day on in-stock orders placed before 4 PM ET.
