Maxilube Systems Operation

      The patented Maxilube System can be operated by a push button remote switch, an on/off switch at the drivers seat/helm station or simply by turning the ignition switch to the "ON" position. This first position activates the pre-lube cycle of the oil lubrication pump. This oil pump timer is designed to run the pump for 1 minute. After this lubrication cycle is completed, the engine is now ready to be started. The engine has now been pre-lubricated, eliminating the "Dry Start" wear condition that is common to all engines. "Dry Start" wear accounts for 53 - 80 percent of all engine wear and is no longer a problem. Once the engine has been started and is running, the engine’s oil pressure pump takes over to lubricate the engine’s internal moving parts. The bypass oil filter heating element, located on top of the oil filter housing, is activated when oil pressure reaches 5 psi. raising the evaporation chamber temperature to 195 degrees which starts the process of eliminating the harmful liquid contaminates, fuel, water, and anti-freeze. A cotton fiber filter medium neutralizes acidity found in the oil. Flow rate of oil after warm up is regulated at 6 gallons per hour. This 1 micron oil filtration system offers superior cleaning properties not found in any other system in the marketplace. This "bypass" filtration system operates as an addition to the engine's full flow oil filtration system whenever the engine is running and does not affect oil pressure. Oil analysis is prescribed at the normal oil filter change indicating the condition of the oil as well as engine wear patterns and takes less than 2 minutes to perform. At engine shut down an automatic timer for the lubrication pump is again activated, providing post lubrication protection for 3 minutes then shuts off automatically. The oil initially enters the bottom of the bypass filter by way of a "T" fitting in the oil pressure sender path and returns via gravity to the crankcase. The electronic oil flow sensor, located down stream of the discharge flow returning to crankcase, sends a signal to an LED display panel indicating proper flow operation. The heater element sensor allows for indication and measurement of electrical current to be recognized on the display panel also. When oil flow has been interrupted or electrical current has been compromised on the heating element, an indicating LED informs the operator to "check oil flow" or "check heating element" needs addressing. The system is working properly when the operator sees both display LED’s "ON" before start up. As soon as oil pressure exceeds 5 psi. the heating element LED turns "OFF" indicating proper heater activation. After the engine is started, the oil flow indicator LED also turns "OFF" indicating a positive flow condition. The display lights will automatically turn "ON" a short time after shut down and post lubrication is completed. The automatic cycle repeats every time the engine is operated.

Filter Specifics

Why a bypass system is needed...

Newer engines, designed to meet strict emission regulations, generate greater amounts of soot in the oil. This soot, along with other solid contaminants, fuel, and water, cannot be effectively and completely removed by full-flow filters alone. This means, without a bypass filtration system designed to remove these contaminants, the oil will become dirty much faster — accelerating engine wear and requiring it to be changed more frequently.

How it works...

Contaminated oil enters through the metering jet at a slow measured flow rate.

The oil then passes through the replaceable filter element, where total base number (TBN) additives are replenished and the unbleached, CGP® treated, long-strand cotton fibers, tightly compressed to resist channeling, remove contaminants down to less than one micron, while neutralizing acids and sulfur compounds.

The filtered oil then enters the heated evaporation chamber, where fuel and water are evaporated and immediately vented.
The clean oil is then gravity-fed back to the sump. The puraDYN® bypass oil filtration system does not affect the engine’s oil flow or pressure.

It does not replace the conventional full-flow filtration system - it enhances and works in conjunction with it.

Installation Notes...

The unit is installed downstream of the existing full-flow filter. Contaminated oil, with abrasive particles, soot, liquids and oxidation by-products known as gum and/or varnish, enters the unit through a small metering jet under pressure supplied by the engine's pump. The metering jet prevents any drop in oil pressure and slows the oil down to a low, measured flow rate of six to eight gallons per hour.

Oil passes through the replaceable filter element where the TBN additives are maintained by the patented time-release additive package, while the long-strand cotton fibers trap solid particles down to below 1 micron and neutralize acid and removes sulfur compounds. In addition, puraDYN® filter elements with their optional process for chemical grafting, CGP®, can double the life of the replaceable filter element. The filtered oil then enters the puraDYN® heated evaporation chamber where fuel and water are evaporated and immediately vented. After the dangerous contaminants are removed, the clean oil is gravity-fed back to the engine.
