CYLINDER AS-MASTER 5V4003 - Caterpillar

A new 8T1000 Electronic Position Indicator Group is available for use in calibrating, monitoring and testing fuel injection pumps. The new group is a battery operated, precision linear measuring gage with a digital readout and storage memory. The storage memory will record the minimum, maximum and difference values of the measurement being taken. It replaces mechanical dial indicators and allows readings to be taken in applications where mechanical dial indicators would fail, such as rapidly changing dynamic readings. The indicator and probe are designed with special electronic filtering to eliminate "gage flutter" and allow monitoring of the fuel injection pump rack position on an operating engine. Fuel settings can be monitored while the engine is operating under load. Static fuel settings can also be taken. The new group will give either inch or metric readings.
8T1000 Electronic Position Indicator Group.The 8T1000 Electronic Position Indicator Group can also be used on fuel equipment test benches as a permanent installation, for testing and calibrating fuel injection pumps. The indicator group has a "floating" zero. By pressing a touch switch, the display can be set to zero anywhere in the measurement range of the probe. The display will then show the distance and direction the probe shaft moves from this zero position.
The standard 8T1002 Probe, part of the 8T1000 Electronic Position Indicator Group, has a 25.4 mm (1.00") measurement range. It has a 9.52 mm (.375") diameter mounting stem and a 19.0 mm (.75") body diameter that allows it to be mounted and used with standard dial indicator fixtures and accessories. Extension cables allow the indicator group to be used from remote locations.
The Tool Announcement gives additional information and features for the 8T1000 Position Indicator Group. Special Instruction SEHS8623 gives information on the use, calibration and operation of the 8T1000 Electronic Position Indicator Group.
