How should you check and install piston rings before engine assembly on Chevrolet Astro?

Upon preparing to fit new piston rings, the gaps should be checked on the ends; the piston ring side clearance must have already been checked. Take piston /connecting rod assemblies and new ring sets and arrange them in the form of the piston and cylinder for the end gap measurement and further engine assembling. Place the first ring in the first cylinder-it must be parallel to the cylinder wall; to do this, push the piston with the first ring near the bottom of the cylinder. For the purpose of determining the end clearance the feeler gauges are inserted between the ends of the ring until the required gauge width is attained provided the ring is square to the cylinder bore. The feeler gauge should be placed between the two rings, it should be a tight fit; then check the measurement with the specified measurement. If the gap is small, it has to be increased so that the ring ends do not come in contact with each other during the running of an engine which is dangerous. Cautiously, file off the ring ends outside the inward to make the gap wider. End gap carries no ill-effects unless the figure crosses 0.040-inch so look at the rings again if these need correction. Perform the same for the other rings in the first cylinder and the other cylinders, where rings, pistons and cylinders must be numbered. After the inspection of the ring end gaps, place the rings on the pistons, and the first one is the oil control ring, which is made up of three members. Insert the spacer/expander into groove, make sure that any anti-rotation tang has been placed into the hole drilled. Sometimes it is possible to damage the piston ring using the piston ring installation tool hence this lower side rail should be installed without using this tool then install the upper side rail in the similar manner. Following the installation of the three oil ring components, make sure that both of the side rails will rotate freely in the groove. Thereafter, place the middle ring with the stamped mark facing upwards and as earlier noted, the procedures for inserting the ring may vary depending on the manufacturer. Insert the piston ring with an installation tool it is placed into its middle groove, the identified mark should be up most of the piston. Last, place the top ring referring the position of the mark upward and one should be very careful on the difference between the rings of the middle and the top rings. Follow the aforementioned process to all the pistons and rings which are left.

Chevrolet Astro Piston Ring

The Piston Ring in Chevrolet Astro vehicles is used to seal the combustion chamber thereby facilitating a proper burning of the fuel air mixture while at the same time preventing gas loss and controlling the consumption of engine oil. These types of rings are ordinary circular cross-section rings mainly produced from cast iron or steel, they are intended to have minimal friction as well as the ability to seal sufficiently to retain functionality and prolong the life of the engine. Through out the years, Chevrolet Astro has used traditionally autos' cast iron piston rings as well as today thinner models. New frame additions have incorporated improved slim rings, for instance 1mm top and second rings that minimise friction and improve the sealing of frames. These thin piston rings are coated with plasma-moly or chrome and its uses are to enhance the durability as well as heat resisting capability.

Each OEM Chevrolet Astro Piston Ring we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
