Cylinder sleeves are largely used by cast iron castings and aluminium engine blocks manufacturers to repair damaged and worn out products. To save the engine block, one must install a repair sleeve if a cylinder is cracked, or has intense taper wear, or damaged, and bore out the damaged cylinder. For restoration of cylinders to like-new dimensions, one can re-sleeve all the engine cylinders in the blocks (in case all the cylinders are drastically worn).

The major benefit to sleeve rather than to bore out the cylinder and install oversize rings and pistons is that it saves cost as you don’t need to replace the rings and pistons. Moreover, several blocks manufactured at foundries are too thin and thus can’t accommodate overboring without cylinder sleeves.

Sleeves components offer vast number of advantages when it comes to high performance applications. One can easily increase the engine’s displacement for heavy wall casting block by boring the cylinders to oversize or by using a stroker crank.

Stroker cranks are famous in the market as they require lesser modifications. When the person is building a high revving performance engine, he may require raising the bore size instead of depending on increased stroke to generate more power. In case you want to install dry sleeves in the block to raise displacement, you can eliminate excessive metal prior running out of block to support the bigger cylinder sleeves.

Things To Consider For Installing Dry Sleeves-

  • Determining the interference to fit the application
  • Smooth finishing inside the bore
  • Torque plates usage to minimize cylinder bore distortion

Way To Install Sleeves:

  1. Chill or freeze the sleeves
  2. Preheat the block
  3. Place the sleeves inside a household deep freeze
  4. Pack them with dry ice or spray liquid nitrogen
  5. Push the sleeve into place and use a mandrel for it

In this way the installation of cylinder sleeves gets completed.
