The Clarke model numbers reflects the base engine type, number of cylinders, cooling system, approval listing,
manufacturing location, emissions code and a power rating code.
Example: C18H0-UFAC28
• C = Caterpillar base engine
• 18 = base engine displacement (18.1 liter)
• H = Heat Exchanger cooled (R = Radiator)
• 0 = Non-Hazardous Location
• UF = Underwriters Laboratories Listed/ Factory Mutual Approved, (NL = Non-Listed)
• A = Manufacture Location (United States)
• C = Tier 2, D = Tier 3, A = Non-Emissionized
• 28 = Power Rating Code
Safety, Caution and Warnings
ATTENTION: This engine has components and fluids that reach very high operating temperatures and is
provided with moving pulleys and belts. Approach with caution. It is the responsibility of the builder of the
machine using a Clarke engine to optimize the application in terms of maximum end user safety.
Basic Rules
The following recommendations are given to reduce the risk to persons and property when an engine is in
service or out of service.
Engines must not be used for applications other than those declared under “Scope of Supply”.
Incorrect handling, modifications and use of non-original parts may affect safety. When lifting the engine, take
care to use suitable equipment to be applied to the points specially provided as shown on the appropriate
Engine Installation Drawing. Engine weights are shown in Figure #1-2
Figure1-2
Figure #1-3 shows the typical lifting arrangement of a bare engine. Note the lifting points on the engine are for
lifting the ENGINE only. Caution, when lifting, lift point should always be over the equipment Center of Gravity.
Figure #1-4 shows the typical lifting arrangement of a base mounted engine and pump set when the base (or
module) is furnished with lifting holes.
When Clarke furnishes the base (or module) for the engine and pump set, the combined weight of the engine
and base (or module) will be indicated on the unit. Caution, when lifting, lift point should always be over the
equipment Center of Gravity.
