But perhaps unnoticed in all of this is the potential damage to vehicles that have been subjected to high waters, not enough to ruin engines and vehicle interiors, but high enough to cause unseen damage.
In particular, the differentials of rear wheel or 4 wheel drive vehicles are subject to drawing in water through vent holes that can quickly cause premature failure of gears, bearings, and seals.
In order to accommodate the ever-changing air pressures within differential housings, they typically have a mushroom-shaped breather vent located on top of the axle housing. This allows the axle assembly to "breathe," allowing air to flow in and out as internal pressures change.
The problem is, when water is mid-wheel deep, or when driving through flooded areas, water can enter the axle housing through this vent. And when water enters the differential area, it can quickly compromise the lubricating qualities of the gear oil, which is especially critical given the very high loads experienced by the meshing gears. The result can be costly gear damage, as well as the onset of rust, which can quickly degrade the lifespan of gears, bearings, and seals.
Penray has introduced a special cleaning agent for just such situations, Penray's 7612 Crankcase and Differential Cleaner, which is specially compounded to remove moisture and other contaminants from differentials and engine crankcases.
The product is simple to use. When cleaning differentials, simply drain or suction about 12 fluid ounces of lubricant from the differential, add Penray's new Crankcase and Differential Cleaner, and roll the vehicle forward and backward 20 to 30 feet to distribute the product throughout the inner workings of the differential. Then drain and refill with the appropriate lubricant such as Penray's Synthetic Gear Oils #3532 and #3632.
Once deep waters have receded, the use of this new Penray differential cleaner will cleanse the entire differential mechanism, assuring a long and trouble-free service life.
