"Big Huskie"

Type -This engine is a semi-high speed, four-stroke cycle engine; L head type with cylinder head removable. Can be supplied in true right and left hand motors.

Cylinders—The cylinders are cast en bloc and have large water spaces around the cylinder walls, properly cooling cylinder and pistons under the most trying conditions. Both cylinder and jacket walls are of extra thickness, allowing for many years of salt water action and the possible regrinding of cylinders.

Pistons—The pistons are of hard gray iron, ground to extremely close limits. They are of liberal length. assuring long service. Each piston is carefully balanced, and fitted with three rings. Piston pin bosses are bushed and fitted with small snap rings to retain the full floating type wrist pin.

Wrist Pin—Of high-grade low carbon steel, hardened and ground to accurate size. Full floating type.

Connecting Rods- Of I beam section, carefully designed for strength and lightness. They are exceptionally long and are fitted with bronze back~ babbitt-lined bushings.

Crank Shaft Main shaft 2-inch diameter, crank pins 2-inch diameter. Crank shaft is perfectly balanced and, together with the perfect balance of all reciprocating parts, makes this motor practically vibration-less.

Base— Sub-Base- Split type. High-grade gray iron casting. Crank shaft bearings are retained in the top base. Large hand hole openings with readily removable covers on side of top base. Bottom base is of good width and extends full length of motor and clutch case.

Bearings—All crank shaft bearings have removable bronze back, babbitt-lined bushings.

Valves -These are of the poppet type, of very liberal diameter and easily removable. Non-corrosive steel.

Valve Gear —Designed for quiet and efficient operation. All parts quickly and easily removable. Rocker shaft, and rocker arms, assembled in one unit. Rocker lifters are of the flat foot type of exceptional width for quiet operation and long life. Valve adjustment easily made by adjusting screw on rocker lifter.

Cylinder Head—The cylinder head is a gray iron casting. Is easily removable. Spark plugs are in the head on admission side.

Admission and Exhaust Manifold Exhaust manifold cast integral with cylinder. Admission manifold cast separate and bolted to cylinder. Admission manifold is hot water jacketed.

Carburetor Down draft. Standard equipment.

Ignition High tension magneto is standard equipment when engine is sold without electric starter or generator. Distributor is standard equipment when engine is sold with electric starter and generator. Magneto can be supplied if double ignition is desired. Magneto price listed on Price Sheet.

Bronze Water Pump—The circulating water pump is of the herringbone geared type, and runs crank shaft speed. Can be quickly removed or installed.

Water Circulation—The cold water coming from the water pump is led into the water jacket. Thence it is circulated around the exhaust and admission valves and is finally taken out of the cylinder head and into the admission manifold jacket and out.

Flywheel —A gray iron casting, machined all over and carefully balanced. Has steel starter gear shrunk
on. Flywheel lock nut is designed for the purpose of pulling flywheel which is bored taper to fit crank shaft.

Reverse Gear —This is our Model YCHS reverse gear. Full floating in gear box and running in a bath of oil. Adjustments easily made through top of gear box.

Lubrication is accomplished through the use of a plunger type oil pump, driven off the cam shaft. The oil is led through the filter and sight feed oiler. The connecting rod and cylinder lubrication is through the splash system, by troughs located in the base. Clutch is oiled separately.

Starter and Generator—The starter is of the outboard barrel type and mounted in flywheel housing. Easily removable. A steel ring gear is shrunk on flywheel. The generator is mounted on a bracket above starting motor and is driven by silent V belt off crank shaft. The mounting is adjustable and readily removable.
