Useful Information On The Available Types Of Piston Ring Compressors

When pistons are installed, the first step would be to clean the cylinder bores with a lint-free, clean towel and apply a tiny amount of standard (non-synthetic) oil to the walls. It would be useful to oil the piston rings and wrist pins too. There is a cautionary deliberation here, though. The piston doesn’t have to be drenched in oil. You only need enough oil to lubricate the rings when they pass through a piston ring compressor.

Types Of Piston Ring Compressors

Generally speaking, you get two standard types of ring compressor formats available for purchase on the market. Expander types which are clamped over a piston to fasten it in place or a tapered job where the rings are gradually tightened when a piston gets pushed through it into a bore. In both cases, the idea is for the compressor to be coated with oil (it mustn’t be dripping wet). Turn the crankshaft for the crank rod journal to be at the top center for a piston that you are installing. The piston/ring compressor combination must be placed over the cylinder bore and ensure that the piston is correctly oriented. For the most part, the piston can be hand-pushed in. In other instances, a light tap with a dedicated piston hammer’s handle will do the job. If excessive force is required, it indicates that the oil ring is not installed properly.

Expansion On Piston Ring Compressors

Band-style adjustable ring compressors are at the lowest end of the scale. The assemblies are fabricated for expanding to fit the most standard commercial and automotive engine bore sizes (Expanding from 3.5 inches to 8.00 inches). You can visit this website to find out more about the best piston ring compressor for your needs. There are more examples available, which range from 2.125 inches to 5.00 inches in diameter. The kind of ring compressor is low-priced (under &15), but they are considered to be slightly shaky to use. The sharp walls of the band clamp can nick your fingers if you are not cautious. You get ring compressors that are designed to work with a dedicated band clamp for every cylinder bore. A set of pliers must be used for attaching the band clamp, which permits you to grip the compressor while tapping the piston into the bore.

Using Tapered Ring Compressors For Making Piston Installation A Little Easier

A less complicated method of installing pistons is by using a tapered ring compressor. The ring compressor gets machined from aluminum with an internal tapered shape. This permits rings to gently compress when the piston is tapped (or pressed) into the cylinder bore. Some of the more superior examples come with a positive grip on the exterior surface, which makes it possible for you to hold the compressor firmly as the piston is worked into the bore. Many tapered designs are internally honed to size. Some are hard anodized for endurance. The disadvantage of a tapered ring compressor is the necessity for a different compressor for every bore size that you are working with.
