A method of manufacturing an engine connecting rod includes mounting a rod on a first mount configured to rotate, mounting a cap on a second mount configured to rotate, positioning a spindle head such that a tool of the spindle head contacts a first connecting end of the rod, machining the first connecting end by spinning the first mount, machining the first connecting end by moving the spindle head, positioning the spindle head such that the tool of the spindle head contacts a second connecting end of the cap configured to be coupled to the first connecting end, machining the second connecting end by spinning the second mount, and machining the second connecting end by moving the spindle head. The spindle head is moveable in a first direction extending between the first and second mounts, a second direction perpendicular to the first direction, a third direction perpendicular to the first and second directions, and rotatable about an axis.

A method for repair of a cylinder block including a water ferrule having damage in an area proximate to the water ferrule is disclosed. The repair method includes removing material from the area containing and surrounding the damage. The method also includes providing a counter bore sized to surround the removed material. The counter bore is configured to define a seat at the one end of the water ferrule. A sealing member is aligned and introduced into the seat of the counter bore. The method includes aligning a stepped insert coaxially with the sealing member and the seat. The method also includes a step of introducing the insert into the seat of the counter bore to form an interference fit therewith. The method further includes providing a seal formed by a combination of the sealing member and the insert within the seat of the counter bore.

A method of manufacturing an engine block is disclosed. In one embodiment, the method includes providing an engine block including a cylinder bore and a top deck with a head face including a predetermined surface roughness. The method also includes masking the cylinder bore with a masking plug, the masking plug being located at a predetermined insertion distance measured from a masking plug outer surface to the head face. The method further includes applying a corrosion resistant coating to the top deck over the head face and machine finishing the engine block including the coating to the engine block specifications.

A method of increasing oil pressure in a heavy duty truck engine lubricating system is provided. The lubricating system comprises an oil pressure regulating assembly mounted in an oil filter base and having a main spring to regulate oil pressure, and a high pressure relief valve assembly mounted in the oil filter base and having a peak clipping spring to relieve oil pressure when the pressure exceeds a specified limit. The method includes the steps of replacing the main spring with a replacement main spring having a higher spring constant and replacing the peak clipping spring with a replacement peak clipping spring having a higher spring constant. A replacement kit for increasing oil pressure is also provided.

Embodiments of an oil pump for an engine have an increased pump capacity while maintaining or marginally increasing the overall physical size of the pump. In some embodiments, this increased capacity is reflected in a pump length efficiency ratio, which compares an effective gear length (L) of first and second pump gears used in the oil pump, to an effective housing length (L). The effective housing length (L) is a longitudinal distance between surfaces on opposite ends of the oil pump that must be maintained for the oil pump to fit into an available space. Accordingly, the pump length efficiency ratio indicates how much of the effective housing length (L) can be occupied by the gears. Alternatively, the pump capacity is measured using an output flow efficiency ratio, which compares a theoretical pump flow (F) at a given gear speed (S) to the effective housing length (L) of the pump.

A method for manufacturing an engine block includes removing material from the top deck of the engine block surrounding a first opening to create a first recessed area, placing a first seal within the first recessed area, positioning a first insert within the first recessed area and against the first seal. The method may also include removing material from the top deck of the engine block surrounding a second opening to create a second recessed area that at least partially overlaps the first recessed area, placing a second seal in the second recessed area and positioning a second insert within the second recessed area and against the second seal.

A method for manufacturing an engine block, such as for an internal combustion engine, includes a step of removing material from a top deck of the engine block surrounding a cylinder bore to create a first removal area. Material is also removed from the top deck of the engine block surrounding at least one fluid passage to create a second removal area. An insert is positioned within a recessed area defined by the first removal area and the second removal area.
