Used by Service Engineers, Repairmen, Crankshaft Grinders, Production Supervisors, and
Quality Control Inspectors, DIATEST Crankshaft Gauges measure the WEB DEFLECTION
of crankshafts in:-
Ready-to-operate engines or compressors.
Assembled engines or compressors, with connecting rod in place.
Assembled engines or compressors, with connecting rod removed.
Dismantled crankshafts, between centres.
DIATEST Crankshaft Gauges are sturdy in design and furnished with hardened gauging points.
They are ideally suited to rugged working conditions.
DIATEST Crankshaft Gauges are supplied in Sets consisting of a dial gauge unit with
spring-loaded (live) gauging point and a full set of gauging extensions and fixed gauging points
to suit ranges stated. The Sets come in fitted hardwood cases.
Set	Range (distance between webs)	Dial grad.
KP-150	45 to 150 mm	0.01 mm
KP-300	60 to 300 mm	0.01 mm
KP-500	60 to 500 mm	0.01 mm
KP-150-Z	1.75 to 6”	.0005”
KP-300-Z	2.36 to 12”	.0005”
KP-500-Z	2.36 to 20”	.0005”
Sets KP-300 and KP-500, and Sets KP-300-Z and KP-500-Z use the same box, and their
component parts are interchangeable. Extensions to increase the range of Set KP-300
(KP-300-Z) to 500 mm (20 in.) are available separately. Sets KP-150 and KP-150-Z use a different
dial gauge unit which is not interchangeable with the two larger sets.
Given the care normally accorded to inspection equipment, the only maintenance DIATEST Crankshaft
Gauges require to provide many hours of trouble-free service is a few drops of a light, resin-free oil
spread on the live gauge point.
The DIATEST Crankshaft Gauge converts to a CYLINDER GAUGE by means of a set of ball-nosed
anvils and cap, available as an accessory.
