Specifications:

Hydraulic Oil Pressure Test Gauge Set – A & D Type, J Type, or LH Type Laycock de Normanville Overdrive, functionally equal to / better than Churchill L.188, and Churchill adapter L.188-2, [BL tool 18G251 and 18G251E (LH)] which have long been out of production and are very rare.

The oil pressure gauge is the key tool for Laycock de Normanville Overdrive problem diagnosis and repair.

The oil pressure gauge is the key tool

for Laycock de Normanville Overdrive

problem diagnosis and repair.

The Gauge Set Consists of:
  • Custom machined steel fitting to replace the operating valve plug. (A & D Type)
  • Custom machined steel fitting to connect to the test port near the solenoid (J Type)
  • Custom machined steel fitting to replace the relief valve plug (LH Type)

  • 0 > 600 PSI – 2.5 inch diameter pressure Gauge – liquid (glycerin) filled, which helps absorb vibration and pressure spikes, increasing the service life of the gauge. The dampening action of the liquid also reduces pointer flutter and lubricates the internal parts of the gauge.

    The allowable operating/ambient temperature range for the glycerin is -4F to 140F (-20C to 60C).

    Gauge: 304 stainless steel case, polycarbonate window, black finished galvalume pointer, galvalume dial (white background with blue and black markings), brass movement, phosphor bronze bourdon tube.

  • Associated brass connecting fittings. (A & D Type)
  • High pressure 3000 psi hose and brass connecting fittings (J & LH Type)
