• Inspect mating STC® fittings to ensure they are in good condition, clean and free of contaminants, nicks, scratches, flat spots, etc.

• Check the Latch Ring (C) to ensure that it is in proper position in the female STC® connector prior to installation or connection.

• Check the O-Ring (A) to ensure it is not cut or otherwise damaged prior to installation or connection.

• Check the Back-Up Ring (B) to ensure it is not damaged. Verify that it is at the front of the O-Ring groove prior to connection the fitting.

• If any damage is detected on either of the O-Ring, Back-Up Ring or Latch Ring, replace them by following these procedures:

1. Carefully remove O-Ring (A) and Back-Up Ring (B) with an O-Ring pick with out damaging the interior surfaces of the fitting.

2. Inspect the interior surfaces and grooves of the fitting and ensure that they are free of foreign material or nicks, scratches, dents, etc.

3. If undamaged, clean the fitting and install the Back-Up Ring (B) at the front of the O-Ring groove.

4. Install the new O-Ring (A) in the groove behind the Back-Up Ring (B) and inspect to ensure that the O-Ring and Back-Up ring are secure in the groove. Lubricate the O-Ring with clean hydraulic fluid CASE AKCELA NEXPLORE™ FLUID.

For each adjustment operation, select adjusting shims and measure the adjusting shims individually using a micrometer, then add up the recorded values. Do not rely on measuring the entire shimming set, which may be incorrect, or the rated value shown on each shim.

Lubricate the O-ring seals before you insert them in the seats. This will prevent the O-ring seals from overturning and twisting, which would jeopardize sealing efficiency.

Apply a sealing compound on the mating surfaces when specified by the procedure. Before you apply the sealing compound, prepare the surfaces as directed by the product container.;
