All rights reserved. WISECO PISTONS & PARTS L.A. Sleeve Co. L.A. Sleeve produces a complete watercraft line of two stroke centrifugally spun iron cylinder sleeves. LASCO sleeves with exact port specifications, chrome-moly iron alloy, high tensile strength material provide the rebuilder with ease if installation, trouble free boring and a lasting long life engine. ★ Column Code Explanations: AC – Original cylinder bore is alloy-chrome plated, Nikasil, or electrofused. The cylinder must be bored to accept the new cylinder sleeve. CS – Original block has a cast-in sleeve liner in the cylinder. The cylinder must be bored out to accept the new cylinder sleeve. The cast-in liner will be bored completely out of the cylinder. Do not try to push out the cast-in liner, cylinder damage may be the result. CI – Original block has a cast-in liner in the cylinder. The cylinder must be bored to accept the new cylinder sleeve. When using a CI style sleeve the cast-in liner will not be completely removed. The sleeve is de- signed to insert into the iron lined cylinder. RS – Original block has a replacement sleeve. Heat the cylinder to remove the sleeve. Reheat the cylinder to install the new cylinder sleeve. CC – Original barrel is cast-iron. The cylinder must be bored to accept the new cylinder sleeve. General Rules for Sleeve Installation: These tips are intended to be a guide for installing sleeves into cylinders. There are always exceptions to the rule and care must be taken on special applications. ALWAYS WAIT UNTIL THE SLEEVE ARRIVES BEFORE BEGINNING ANY MACHINE WORK. NEVER ASSUME THAT THE STATED MODEL AND YEAR OF THE CYLINDER IS CORRECT. ALWAYS CHECK TO SEE IF THE SLEEVE PORTS MATCH THE CYLINDER PORTS. 1. Interference fit for cylinder sleeve to aluminum bore is .004. 2. Interference fit for cylinder sleeve to a cast iron bore is .002 to .003. 3. Installation of flanged type sleeves follow the same rules, but the top of the cylinder must have a countersink to the correct depth to accept the flanged sleeve. .000 to .001 interference fit on the flange diameter is recommended. 4. Heating the cylinder for 45 minutes to one hour at 350 degrees to 450 degrees is preferable. 5. The sleeve should slide in very easily when the cylinder is properly heated. Freeze shrinking the sleeve is not necessary. (Some machinists believe this assists installation of the sleeve.) 6. REMEMBER: Rap or press the sleeve down while the cylinder is cooling down. Use a hydraulic press for this procedure. 7. Milling the top deck of the cylinder always adds a quality touch. A caution here, some cylinders may not be able to have the top surface decked. 8. For two-stroke cylinders, blending or matching the aluminum cylinder to the sleeve ports is recommended for proper fuel flow. **See page 186 for more information about sleeves** Piston Wrist Pin Bearing Crank Side/End Rod Bearing Piston Style Model Sea-Doo Stock En- gine Bore x Stroke ★ L.A.
