P-300 Gage

Your new P-300 Gage is a hand-held comparator-type gage which uses probes to measure the clearance between valve stems and guides (see Figure 1). It will gage reamed, honed, knurled, or bronze insert guides. Any desired diameter within the range of the probe used can be set into the gage.

1. DIAL INDICATOR - Reads in .0002" (0.005 mm) increments over or under the set diameter. Each numeral marks .001" (0.05 mm); total range of dial is .015" (0.37 mm).

2. GAGE BODY - Incorporates probe adapter for seating and holding probe.

3. ADJUSTMENT SCREW - Used to "zero" gage when setting; operated with Wrench, Item 9.

4. RETRACTING LEVER - Depress to reduce gage point diameter when inserting probe in setting fixture, valve guide, or when making readings at various points along valve guide.

5. T-HANDLE - Used for holding and balancing gage when measuring valve guides.

6. PROBE LOCKING SCREW - Securely holds probe; loosen and tighten with Wrench, Item 9. 7. PIVOT BEARINGS - Self-locating design assures repeatability in readings.

8. SUPPORTING FOOT - Provides a rest point in conjunction with T- Handle to support gage.

9. 1/8" (3 mm) HEX WRENCH WITH KNURLED KNOB - Has rounded knurled handle; used for locking probe in place and adjusting gage to desired setting.

10. .050" (1,25 mm) HEX KEY WRENCH - Used when servicing Retracting Lever.

Gaging Probes

Each probe is self-contained but can be disassembled for service (see Figure 2). When assembled to Gage Body and correctly set with a master of known size, a probe will gage any diameter within its design range (refer to Table 1).

1. GAGING POINTS - Opposed Points are long enough to bridge the grooves in knurled guides and give accurate measurements in all types of guides.

2. HEAD - Ground diameter gives proper seat in P-300 Gage. Flat on Head assures correct installation. Countersink opposite flat provides positive locator for Probe Locking Screw (Item 6, Figure 1).

3. WEDGE - Transfers size from Gaging Points to Gage.

4. 5/64" (2 mm) HEX KEY WRENCH - Used for servicing probe.
