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

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)


Oil filter

Welded-pipe exhaust manifold (this is a 'four-legged' assembly that combines the four outlets from the bank manifolds into one pipe)

I am attempting to obtain an estimate of the cost of replacement air starting check-valve components. I doubt the engine would need multi-pass oil or water heat exchangers just to run at idle speed - homemade coolers would probably suffice for display operation. The other items should not be difficult to obtain.

We have been trying to get Dresser-Rand Co. (successor to Ingersoll-Rand) sponsorship to help relocate the engine to an interested club or organization, but at this time we do not have a final answer.

Time is running out, because the LNVA plans to remove the engine from the pump house very soon. If we can secure a new home for the engine, LNVA personnel will perform preservation procedures before the engine is removed from the pump house. The LNVA will cover the crane cost if a transport truck is on-site when the engine is removed from the pump house or when the replacement engine is being installed. Any interested organization should contact me at work (607) 937-2355, or at home (570) 827-3129.
