Ingersoll-Rand 8PLVG, One of Only Six Made, at Risk of Being Destroyed


| February/March 2003



Ingersoll-Rand Model 8PLVG

The Ingersoll-Rand Model 8PLVG in its current intallment in Beaumont, Texas. This is one of only six of these huge V-8 engines made.

The engine shown below spent its working life driving a water pump in one of the Lower Neches Valley Authority (LNVA) pumping stations in east Texas. These pumping stations feed water into a canal system to provide irrigation for farms and to provide salinity control in recreational lakes.

This engine is being retired, and the LNVA is willing to donate it to an interested engine organization rather than scrapping it. The PLVG is a power engine version of the model LVG integral engine-compressor. This unit, serial number 8AZ100, was the first of only six 8PLVG engines manufactured. It was shipped from Painted Post, N.Y., on April 20, 1939. The LVG/P was the first vertical cylinder, overhead valve model engine built by Ingersoll-Rand. It has a 14-1/2-inch bore by 18-inch stroke and is rated 650 HP at 300 rpm. The LVG went into production sometime after the 1932 introduction of the smaller model XVG (an L-head engine) integral engine-compressor, and is the model from which the larger Ingersoll-Rand engines evolved. The model letters stand for Large Vee Gas.

My contact at the LNVA says some parts will be robbed from the engine for spares for the other PKVG engines in the plant. The missing items are:

Starting air check valves (for the air to head starting).

Heat exchangers for the oil and water.

Governor (The governor driven gear will go with the engine)
