Cylinder Sleeves
Jet Ski Cylinder SleevesSBT's jet ski cylinder sleeves are an economical solution for repairing cylinder blocks back to OEM specifications. Here at SBT, we make our replacement PWC cylinder sleeves from a proprietary cast iron alloy that are centrifugally cast. They are identical to the sleeves used in SBT's remanufacturing process. The purpose of a jet ski cylinder sleeve is to provide a hardened wear surface for the piston rings. As the piston moves in the cylinder, the cylinder walls can become very worn and damaged. If you leave your jet ski and cylinder alone for a while without inspections or maintenance, you could end up with a whole host of problems down the line. These can affect both the cylinder and your engine. Instead of dealing with these problems down the line, consider using a PWC cylinder sleeve that uses hard metal to restore proper clearance to your jet ski’s engine. There are two types of sleeves: centrifugal spun cast iron and poured cast iron. Poured cast iron is simply poured into a cylinder casting mold. This type of jet ski sleeve is usually more prone to weakness and porosity. The spinning method used to create centrifugal spun cast iron draws out impurities and air pockets from the raw casting material's center to the outer surface, which is then removed. The end product is a sleeve that is greater in micro-structure and density. The jet ski sleeve will then withstand greater loads without losing cylindrical roundness or shape. Another advantage of SBT's cast iron sleeves is that they wear longer and are more resistant to overheating. If you’re interested in keeping your PWC and cylinder block longer, then you should head to SBT and get our cylinder sleeves. |
