maintenance | by Tom Jackson Y es, they're big, bad and power- ful; but today's diesel engines and hydraulic systems can be silenced by the smallest of particles. An 80,000-pound dozer can cough, sputter and die all because of a few particles no thicker than a human hair damage the fuel injec- tors. A teaspoon of dirt can ruin an engine. And just changing from one attach- ment to another can dump enough polluted hydraulic fl uid into your reservoir to quickly ruin the whole system. Clean is the name of the game today. If you're a fl eet manager or equip- ment owner, your fi rst line of defense against contami- nation is your equipment fi ltration systems – fl uid, air and bulk fuel and hydraulic oils. Here's a look at the lat- est state-of-the-art fi ltration systems and what they can do to protect your equip- ment investments and keep your machines running in the fi eld. BULK Your fi rst line of defense – fi ltration for stored fl uids Diesel fuel and hydraulic oil start to degrade almost from the time they leave the refi nery. Give them a couple months in your storage tanks and they'll be ripe with water, algae and asphaltines that can prematurely clog fuel fi lters and lead to fuel injector problems. Your fi rst line of defense in contamination control should be fi ltering your fuel both as its delivered and as it's being pumped out of your bulk storage tanks. The Donaldson Bulk Fuel and Lube Filtration line, for example, cleans, protects, polishes and removes water from delivered fuel and oil with single–pass effi ciency and high fl ow rates. Breathers that prevent dust and moisture from entering the tanks and fi lters on the exit side give your machines the freshest possible fuel and lube oil.

The Mann+Hummel PreLine series for diesel fuel pre-fi ltration now includes six sizes covering engines from 13 to 611 horsepower. The new PreLine fi lters have a water collection area integrated into the spin-on fi lter housing and come with a hand pump for fi lling the spin- on fi lter with fuel after servicing. The modular product range includes water sensors and diesel heaters for the preliminary fi lter.
