SECTION 5- LUBRICATION SYSTEM
These engines use a Pressurized Lubrication Sys-
tem. A rotor-type oil pump pushes oil through
galleries machined into the crankcase. Openings
in the galleries permit oil to lubricate critical
engine components. The center oil pickup ensures
proper lubrication at operating angles up to 30°.
Two types of Pressurized Lubrication Systems are
used on these engines, depending on the engine

In the Pressurized Spray Lubrication System, the
oil pump delivers oil to the main crankshaft and
camshaft bearings at approximately 5 PSI. Lubri-
cation for the connecting rod journals is provided
by oil sprayed from two small holes drilled in the
camshaft. See Figure 5-1.

KT17 Series II and KT19 Series II engines have a
Full-Pressure Lubrication System that delivers oil
to
the crankshaft, camshaft, and connecting rod
journal bearings at approximately 25-50 PSI (see
Figure 5-2). A pressure relief valve, located in the
engine crankcase behind the closure plate, limits I
the maximum oil pressure in the system (See
Figure 5-3). A 1/16" NPTF pipe plug in the #1
crankcase side (PTO end) is removable to permit
installation of an oil pressure gauge (See Figure
5-4).
