Analysis identifies critical leak

A CMI Soil Stabilizer plays a critical role in Nick Savko & Sons’ daily operations. “The CMI soil stabilizer is extremely important to our fleet because it enables us to continue our work regardless of the ground and weather conditions,” says Savko. “Without it, a simple thunderstorm could set our project back two or three days — and that’s not something we like to have happen.”

The soil stabilizer undergoes routine oil analysis sampling via the Mobil Monitor EM/PA II used oil analysis program. In a recent test of one of the samples, Brandt noticed the presence of unusually elevated levels of copper, sodium and potassium, tell-tale signs of glycol in the engine. If left unchecked, the leak could lead to a catastrophic engine failure.

Understanding the potential consequences of the glycol leak, Brandt immediately notified Savko of his concern for the condition of the machine.

“To rebuild that engine in-frame would have cost Nick Savko & Sons upwards of $13,500, plus an additional $10,000 for 10 days of lost production and $10,000 per week for a temporary replacement,” says Brandt. “We felt an immediate need to notify Savko so the team could react and prevent any further damage to the equipment.”

ExxonMobil recommended a pressure test of the cooling system on the cylinders in order to locate a possible seal leak. The pressure test was executed and the leak within the cylinder was located and repaired. Once the repairs were completed, the machine was drained, flushed and refilled with new Mobil Delvac heavy-duty engine oil, and returned to full working order.

“The personal attention ExxonMobil provided not only saved our company more than $25,000 in repair and lost production costs, but also helped preserve the excellent reputation of Nick Savko & Sons for on-time project completion,” Savko says. “Each year, more than 85 percent of our sales come from repeat business due to our ability to meet deadlines and deliver on-time results. The reliability of our equipment plays a major role in maintaining that level of service.”
