Cub Cadet 1535 - Air Cleaner Servicing

filter should be changed at every oil change interval.
The filters can be obtained through your Cub Cadet
dealer under Part Number KH-52-050-02; this is the
only approved filter due to the pressure specifications
required for the 15-HP engine.
To change the oil filter first remove the right side
panel. Drain the oil from the engine by removing the
drain plug. Before the filter is removed, clean the out¬
side surface and mounting base of the filter. From the
operator’s position, turn the filter counterclockwise
using an automotive type filter wrench to loosen.
Before installing the new filter, apply a coating of oil on
the filter gasket. Thread the filter on by hand until tight
enough to seat the gasket. Loosen the filter.
Retighten the filter an additional one-half turn.
Replace oil drain plug and follow "FILLING THE
CRANKCASE” instructions. Check for oil leaks.

SERVICING PAPER CARTRIDGE
This engine is equipped with a dry-type air cleaner
element, which should be checked every 100 oper¬
ating hours and replaced if dirty. It should be checked
and if necessary replaced more often under extremely
dirty, dusty conditions. Do not wash element in any
liquid or attempt to blow dirt off with air hose as this
will puncture filter element. Carefully handle new ele¬
ment — do not use if gasket surfaces are bent or
twisted. Check the following when installing a new
element: (See Figure 34.)
1. Backplate must be flat on gasket of carburetor
elbow. Replace backplate if bent or cracked.
2. Gasket surfaces of element must be flat against
backplate and covered to seal effectively.
3. Seal on cover must be in place to reduce noise
and vibration of the cover. Vibration can cause
stud hole in cover to enlarge, thus permitting dirt
to enter carburetor.
4. Wing nuts must be finger tight — do not over¬
tighten.
Properly cleaned and installed air cleaner elements
are the best guarantee to continued long and satisfac¬
tory engine life.
