are essential for operations in re- mote locations such as in Alaska.

The entire package of the Traktor is factory assembled on an alumi- num "Skid Pak," an integral base section that can be welded directly into a boat, becoming the middle section of the boat's bottom.

The Hurth transmission is a

HBW 450 equipped with a positive- ly driven, mechanically operated helical gearing system. The 3:1 gear box allows the Traktor to operate at 600-rpm shaft speed for midrange performance. The HBW also per- mits direct reversing for back flush- ing the jet drive.

The Traktor's cartridge-type thrust bearing package is designed to have life of more than 10,000 hours and can be replaced in less than 30 minutes—in the water— with no special tools. And the 11 impeller blades can be replaced in- dividually. Damaged blades can be replaced with minimal downtime.

Quiet Cove Enterprises of Ana- cortes, Wash., has built the first production model of the Cummins- powered Traktor, the Kodiak King, which will operate in the Kodiak area salmon and herring fisheries.

Quiet Cove has orders for four more

Cummins-powered Traktor-pro- pelled skiffs, all for the Southeast

Alaska salmon fisher.

Besides commercial fishing, Mr.

Hill sees potential applications for the Cummins-powered Traktor Jet in other types of vessels, such as shallow-draft tour.

Cummins Announces Availability

Of New XA' Series Diesel Engines —Literature Available—

Cummins Engine Co., Inc., which acquired majority ownership of

Onan Corporation in early 1986, re- cently announced an agreement with Hawker-Siddeley and Onan

Corporation whereby Cummins will assume responsibility for the Onan

L series diesel engines. Under this agreement, which covers only the L series diesel engines and not the gasoline models, the engine will be designated the Cummins A series.

With the addition of the A series,

Cummins power range will be ex- panded to 41 horsepower on the low end. This enables Cummins to offer diesel power for a wide variety of applications requiring from 41 to 9,000 horsepower.

The A series is strategically im- portant to Cummins in three areas: 1) Automotive: Since the A series has a small package size and the capability to run at 3,600 rpm, it provides an excellent alternative for customers who have traditionally used gasoline engines, but who want the fuel savings and durability of diesel. In essence, the A combines the strengths of both the gasoline and diesel engines. 2) Industrial:

Cummins is encouraging the world- wide industrial OEM's to standard- ize on Cummins throughout their product range, but to date have not been able to offer a cost-effective engine at the low end. The A series fills this void. 3) New markets: The

A series also provides entry into sev- eral new markets: ground support, welders, lift trucks, and mobile re- frigeration. Cummins thinks this engine will be particularly strong in the U.S. mobile refrigeration mar- ket.

The Cummins A series engine family consists of three-, four-, and six-cylinder naturally aspirated models, as well as a six-cylinder tur- bocharged model. Plans are also in place to develop a four-cylinder tur- bocharged model. These engines, which are smaller than the Cum- mins B series, offer a wide power range of 41 to 120 hp at 3,600 rpm (compared to the B series automo- tive rating of 105 to 186 hp at 2,800).

The A is designed as an in-line, four-stroke, water-cooled engine and employs an indirect injection system.

This new engine family, which began production in September 1981, was designed to provide op- timum application flexibility, in or- der to serve various markets. It was released in 1987 by General Motors as a special equipment option in the

P-40 stripped chassis, and began production in the Ford E350 stripped chassis in Venezuela in

January 1988, and will begin in the

U.S. in March 1988. It is also used in generator sets, marine auxiliary pro- pulsion, small industrial equipment, and automotive repower applica- tions.

The Cummins A engine will con- tinue to be manufactured at Onan's

Huntsville, Ala., manufacturing fa- cility. Product development will re- main in Fridley, Minn. Marketing and aftermarket support will be transferred to Cummins marketing, parts and service groups in Colum- bus.
