DESCRIPTION
GENERAL The vVaukesha 190, 185, 180 series engines are of overhead valve, wet
sleeve construction, all incorporating the same general design features. The 190 and 185 models are six-cylinder engines; the 180 model is a four-cylinder engme.

These engines are designed to give extended service life without specialized or unusual maintenance techniques. Clean oil in the proper quantity; clean, soft, cooling water; and regular attention to such items as air cleaners, spark plugs, fuel strainers, and oil filters will insure continued reliable performance.
CRANKCASE For maximum rigidity and accurate bearing alignment, the crankcase
and cylinder block is cast as a single unit. Bearing cross walls and water baffles are generously filleted and heavy top diaphragms and bottom

flanges locate and support the cylinder sleeves. The sleeves are exposed to cooling water for practically their entire length and are sealed with two rubber rings at the lower end and the cylinder head gasket at the top. No special tools are needed for installation or removal of these sleeves.
CRANKSHAFT The crankshafts used in the 190, 18j and 180 series engines are heat
treated and precision ground steel forgings. These shafts are fully balanced both statically and dynamically. The mirror finished crankpins and main bearing journals are held to extremely close tolerances to accommodate precision bearing shells without the necessity for field fitting.
It is important that the owner be acquainted with the several types of crankshafts from the standpoint of ordering service parts. All crankshafts used in recent Model 190 oil field engines are drilled for pressure lubrication to the connecting rod lower end bearings. Other 190 series engines are equipped with a metered jet lubrication system and incorporated oil transfer recesses in the main bearing journals but are not drilled. This is discussed under OILING SYSTEM.
All crankshafts used in the 185 and 180 series engines are equipped with oil transfer recesses for metered jet lubrication. Current production 185 and 180 engines employ counterbalanced shafts with 2;i" diameter crankpins. A very large number of engines have, however, been built with a conventional crankshaft and 2" diameter crankpins. It is possible to convert an earlier engine at time of overhaul to accommodate a counterbalanced shaft, but this change will probably require some minor reworking of the crankcase for clearance, plus replacement of the connecting rods, connecting rod bearings and pistons.
BEARINGS Precision type copper-lead bearings permit replacement without line
boring. The flanged upper and lower halves of the center main bearing absorb thrust loads on the 180 model and since it is also of the precision type, no special end-play adjustments are required. The same thing applies to the #3 bearings in the 185 and 190 engines. A steel-backed, babbitt-lined bushing supports the gear end of the camshaft. A pre-sized service bushing is available for replacement. Piston pins are full-floating in bored, s teel- backe d bronze bushings in the rods.
GOVERNOR
A self-contained, gear-driven governor is mounted within the 'Sear cover and a small project- Sectional View - Governor
WAUKESHA MODELS 190, 185, 180 7
ing housing. This governor is of the familiar two-weight, centrifugal type, and requires no adjustment other than establishing the desired high idle speed. _-\ screw type surge adjustment is also provided.
If it is desired to change the governor response to adapt to the engine load, repositioning of the governor spring end in the holes to"wards the end of the governor lever will provide slower governor response and less tendency to surge. Conversely, moving the spring end closer to the lever pivot will provide faster governor response but may increase the tendency to surge. After any movement of the governor spring end, it is necessary to adjust the spring tension by use of the adjusting nut to maintain the desired high idle speed.
IGNITION Ignition may be with either a fixed-timing, vertically or flange-mounted
magneto, or with a distributor and coil. With the exception of the flangemounted magneto, used on Model 190 oil field engines and which is driven from the engine gear train, the ignition unit is driven by a spline and key on the oil pump drive shaft upper end. Adjustment and timing of these units are discussed under DISTRIBUTOR TIMING, or, MAGNETO TIMING.
CARBURETION For use with gasoline or kerosene, a standard diaphragm-type fuel
pump is used and driven from an eccentric on the camshaft. Carburetors may be for gas only, for gasoline only, or of the gas-gasoline type as specified. Carburetor adjustments are discussed under a separate heading.
WATER PUMP The water pump requires no special lubrication, packing or attention
during its service life. An internal seal is used in combination with a unittype ball bearing and pump shaft to provide a simple, ruggedly constructed water pump.
Water Pump
OIL PUMP A high-capacity, spring-loaded vane-type pump, driven by a spiral gear
from the camshaft provides oil under pressure to the lubricating system of

OILING SYSTEM The oiling system employed on
the Model 190 oil field engines provides full oil pressure to the crankshaft bearings and rods, then meters this oil supply through small pockets in the crank journals to the accessory gears and valve mechanism.
Oil enters the vane or gear pump through the floating oil screen which picks up from the cleaner upper surface of the oil supply. Lea ving the pressure side of the pump vane, the oil passes upward through a passage in the pump support and is forced into the main oil gallery extending the length of the right side of the engine.
At the front of the gallery (gearcover end) a pressure relief valve of the non-adjustable type prevents excessive pressure build-up. Drilled passages conduct the oil from the gallery to the main bearings. The front and rear main bearing crankshaft journals are provided with small pockets which are so aligned as to index with the incoming oil passage and bridge across the journal to an outgoing oil passage. This happens for a brief portion of each revolution of the shaft. Thus, the
