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 INDICA

TOR - 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. SUPPOR

TING 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.
