Cylinder block sleeving is one of the basic stages of engine major repairing. It supposes cylinders boring, and installing new sleeves (bushings) that serve as cylinder block walls.
The conventional way of installing repair bushings is the method of 'hot sleeving' – it involves heating the cylinder block in a kiln simultaneously with cooling a sleeve in liquid nitrogen to provide interference fit.
The given procedure is rather labor intensive, it requires using a lot of equipment. However, there is an effective alternative for ‘hot sleeving’: it is press fitting.
To provide a regular process of installing sleeves by using a press,
A layer of dray lubricant reduces friction at press fitting, protects against forming scuffing on the mating surfaces.
MODENGY A-MOLY is applied onto the sleeves surfaces by the method of spraying out of an aerosol can. After solvent evaporating, powder of molybdenum disulfide remains on the parts which provides effective separation of the surfaces.
When cylinder block sleeving has completed, it is recommended to blow the parts to remove excess of the dry lubricating material.
Use of MODENGY A-MOLY enables to abandon using the labor-intensive process of sleeving by the ‘hot’ method, to provide high efficiency to the process of press fitting the sleeves.
