Melling Cylinder Sleeves, Manufactures centrifugal cast iron cylinder liners to tolerances as small as one half of one thousandth of an inch, on modern CNC equipment. Our centerless OD grinding process guarantees a part that is perfectly round and to exact size specifications. The material used in Melling cylinder liners offers a Brinell hardness of 241-293, and machines easily with strength and durability similar to that of ductile iron.

Melling Cylinder Sleeves stocks sleeves for a wide range of the most popular automotive applications, as well as sleeves for compressors, lawn care equipment, agricultural applications, and oil field equipment. Melling Cylinder Sleeves offers liners with a broad range of bore diameters, starting as small as 2” up to a very large 8.50” bore, and finished lengths ranging from 1/8” up to 24”. Sleeves are available in 3/32” and 1/8” wall for bore diameters up to 5-1/8”. Bore diameters larger than 5-1/8” are stocked only with 1/8” wall thickness. Melling Cylinder Sleeves also offers 1/16” and 2mm wall thickness’ for limited applications.

Melling Cylinder Sleeves can also make sleeves for custom applications. If you don’t see what you are looking for in our catalog give us a call. Low volume, high volume, honed or semi-finished it doesn’t matter we do it all. Melling Cylinder Sleeves can make a sleeve to your exact specifications and in less time than you think.

Expansion Plugs are a new product to the Melling line. We have a full supply of standard freeze plugs as well as our new "vented" plugs. See our catalog page to request a copy of our new Expansion Plugs catalog.

Melling oil pumps provide dependable performance every time in every application. Every pump is engineered, manufactured and assembled to the highest material and production standards. Manufacturing processes include state of the art CNC machines and the latest phosphate coating processes.

Melling high pressure oil pumps can aid in increasing the amount of oil pressure in engines with low oil pressure. Melling oil pumps provide dependable performance every time in every application. Every Melling high pressure oil pump is engineered and assembled to the highest production standards from high quality materials. All Melling high pressure oil pumps use the latest in gear and gerotor technology to provide the highest level of quality and performance. Gears are machined to close tolerances to ensure proper engine pressure and correct, efficient pump operation. End plates are precision ground for maximum ware resistance. Every Melling oil pump is individually tested for pressure and flow under conditions designed to duplicate actual engine operating conditions.

Listed below is a group classification for the custom (or high) performance camshafts listed in this catalog - (the durations shown are based on .050 cam lift). The descriptions within each group show the characteristics of the cams in that group as well as any recommended modifications to the car or engine that will help get the desired performance. Good idle quality. Low RPM torque and mid range performance. Will work with stock or slightly modified engine. Manual or auto transmission.

CLASS I (200° - 215°) Good idle quality. Low RPM torque and mid range performance. Will work with stock or slightly modified engine. Manual or auto transmission. Possibly lower vacuum than stock.

**CLASS II (215° - 230°)**Fair idle quality. Good low to mid range torque and horsepower. Will work with stock or modified engine. Manual or auto transmission. Possibly lower vacuum than stock.

**CLASS III (230° - 245°)**Rough idle quality. Good mid to high RPM torque and horsepower. For use with manual or high stall auto transmission. May need improved carb, exhaust and ignition systems. Comination street and d rag. Will have lower vacuum than stock.

CLASS IVRough idle quality. Mid to high RPM torque and horsepower. For serious racing. Need proper selection of rear axle ratio and improvements in carburation and exhaust systems. For use with manual transmission or automatic with a very high stall converter. Will not have enough vacuum for power accessories.

Melling Select Performance recommends using MELL-LUBE Engine Assembly Lube to prevent scoring or galling during engine start-up. MELL-LUBE also contains corrosion inhibitors to prevent rust and pitting to new engines. MELL-LUBE is not for use on cylinder walls or piston rings. MELL-LUBE now has 1,400 PPM zinc for better protection.

Always install new lifters (followers) with a new camshaft. Installing used lifters with a new camshaft can cause premature failure of both the camshaft and the lifters.

Do not allow the engine to run under 1500 RPM for the first 20 minutes. The first few minutes of the engine operation are the most critical and tests have shown that if there is no metal pickup or spalling during this period, the camshaft will wear as long as the other engine components.

With performance camshafts - usually you will have to advance the distributor timing (on the vibration damper) more than stock specifications.

When installing any high performance or racing camshafts into an engine, check to make sure there is adequate clearance between the valves and pistons and also make sure the valve springs do not compress solid.

On all engines equipped with roto-coils or valve rotors in either the intake or exhaust positions check for possible coil bind. You might have to change the valve spring and retainer - (using aftermarket high performance valve springs is an alternative).

Melling Cylinder Sleeves, Manufactures centrifugal cast iron cylinder liners to tolerances as small as one half of one thousandth of an inch, on modern CNC equipment. Our centerless OD grinding process guarantees a part that is perfectly round and to exact size specifications.

• Universal flanged sleeves provide extra insurance against sleeve movement in performance applications
• Reduce the critical factors that secure standard liners such as press fit, cylinder ledge at bottom of bore, and heat expansion rates of metals.
• Flange counter bore thickness in block can be machined .002 less to provide extra sealing against the gasket and head from the flange sleeve.
• Bore can be up to .060 bigger than standard and still have 3/32” sleeve wall.

Melling has a line of valve springs for common performance circle track and drag racing applications as well as some custom valve springs.
