Remove the connecting rod using a T20-Torx wrench. The Torx screw is located at the bottom of the connecting rod. Slide the rod off the bearing and check for wear and tear on the piston ring. Slide the cylinder sleeve out from the top of the endbell housing. [pdf]

FAQS about How to remove the connecting rod of a screw air compressor

How do you lubricate a rotary screw air compressor?

Lubricated rotary screw air compressors must use oil to lubricate the screw, which may cause the lubricating oil to contain some fine dust or iron filings. These impurities will reduce the quality of the lubricating oil.

How do I remove the connecting rod?

REMOVING THE CONNECTING ROD [top] 1. Remove the manifold cover. Remove the retaining screw. Lift the manifold cover away from the unit. 2. Remove the pump assembly from the tank. Remove the front retaining screw. Remove the rear retaining screw. Slide the pump assembly to the side. Lift the pump assembly away from the tank.

How do you remove a retaining rod from a pump?

Remove the connecting rod assembly. Insert a screwdriver between the spokes of the pulley and the side of the connecting rod to prevent the assembly from spinning. Use a Torx driver to loosen the retaining bolt. Remove the retaining bolt. Slide the connecting rod assembly out of the pump housing.

How do you install a compressor head?

Align the valve plate assembly (and cylinder gasket) with the compressor pump. (The cylinder gasket and the exposed valves should be facing the cylinder-side of the pump.) Align the head gasket with the valve plate assembly. Install the cylinder head. Install the head bolts.

How do you connect a compressor pump?

Reconnect the rear (white) wire to the field terminal. Align the feet on the compressor pump with the grooves in the housing and slide the pump fully into position within the housing. Reconnect the front (yellow) wire to the field terminal. Reconnect the ground (green) wire to the pump and secure it with the screw.

How do you repair a compressor pump?

Rebuild the compressor pump. Align the cylinder gasket with the valve plate assembly. (The gasket should be seated against the side of the valve plate that contains the exposed valves). Align the valve plate assembly (and cylinder gasket) with the compressor pump.
