A A timing cover protects parts such as the timing belt, timing chain, and gears inside of your vehicle. They are made from either plastic, metal, or a combination of synthetic materials. In modern vehicles, the covers are designed to What is a Compression Test? Browse other content. Smoke from engine or exhaust Inspection.
Oil level is low Inspection. That is because honing creates small crosshatches in the surface of the cylinder, to allow the wall of the component to retain oil and provide lubrication for the piston ring. Even though the instructions for the new piston may specify that honing your cylinder is required, you can also manually check and see if your cylinder requires it. Simply deglaze the cylinder with hot water and SOS pads to thoroughly clean it, and then look inside.
If you can still see the original hone marks cross-hatching then you likely will not need to hone the cylinder. Skirt coatings not only protect the pistons, but also allow for tighter clearances, between the piston and cylinder. As a result, this will reduce piston rocking and blow-by. When measuring piston ring end gap, check the gap with the piston rings; at the top and the bottom of the bore. If the bore has taper the end gap will be; larger at the top and smaller at the bottom.
The ends of the ring may hit each other causing the ring to bind and scuff. Cylinders that have more than. Installation is very important. One of the most common installation errors is; installing one or more rings upside down.
This will usually deform the ring, which can affect ring rotation and seating. So, always use a ring expander. Position the ring on the expander and expand it. Just enough, to fit on the piston. Do not over extend the ring.
Always check ring groove depth, to make sure the rings are the correct ones for the piston. Always measure, piston ring end gaps; to make sure the rings fit the grooves and cylinders correctly. During installation piston rings may become damaged. Check the under side of the ring compressor for damage. Finally, adequate ring and cylinder lubrication is essential for; proper ring seating and protection when the engine is first started.
Above all, scrubbing out the cylinders with hot soapy water; after the block has been honed is an absolute must. Consequently, this will help to remove all the abrasives and other contaminants; that can damage new piston rings.
