Bore Gauge with Box Sleeve Height and Counter Bore Gauge for All Diesel Engines Bore Gauge Range 0-1.00" Graduation 0.001" Reading 0-100

6434 With box Sleeve Height & Counter Bore Gauge For All Diesel Engines Bore Gauge Range 0-1.00" Graduation 0.001" Reading 0-100 The 6434 1-Inch Dial Indicator Sleeve Height and Counter Bore Gauge is designed for use with all diesel engine makes and models.It provides precise measurements for cylinder sleeve height, counterbore depth, piston-to-deck clearance, valve protrusion, and true dead center.Suitable for applications in automotive repair, aerospace maintenance, marine engineering, and heavy machinery diagnostics.This bore gauge features a measurement range of 0-1.00 inches with 0.001 inch graduations and a 0-100 dial scale for accurate and repeatable readings around the entire bore, supporting consistent engine assembly.The kit includes: 4374 Dial Indicator (0-100 scale), 4375 Base, 4377 Flat Anvil, 4378 Pointed Anvil, Hex Wrench, and a rugged carrying case.The self-centering base allows for quick and accurate alignment.The rotatable bezel with clamp enables easy zeroing.Interchangeable anvils—flat and pointed—are included to support different measurement tasks.Use the pointed anvil for cylinder sleeve height and the flat anvil for counterbore depth.The gauge can also measure piston-to-deck height and valve protrusion.To use, insert the indicator into the base and lightly secure the set screw.For counterbore depth, use the flat anvil; for sleeves with coining beads, use the pointed anvil.Place the gauge on a flat and zero the indicator by rotating the bezel.With a clean deck , take direct measurements to the counterbore shoulder and sleeve protrusion height.For engine blocks with open water jackets, the indicator can be reversed in the base, allowing measurement across cylinders up to 5-1/2 inches in diameter for both sleeve height and counterbore depth.
