MOUNTING GP-ATTACHMENT 9R2961 - Caterpillar

Gauges other than the 6V87 Valve Stem Gauges can be used to measure the valve stems. One example of this is the 652 MJZ Universal Dial Bench Gauge. See the illustration. This gauge can be used with metric plug gauges to check all valve stems in Caterpillar Engines. The plug gauges are used to set the dial indicator to the minimum "use again" dimension. The valve stem can then be put in position under the indicator tip. The indicator will then show if the valve stem is within the "use again" specifications.
