Fuel Filter - Model MT and MTL
Models MT and MTL are each equipped with an in-
line fuel filter. Visually inspect the filter periodically,
and replace the filter yearly.
Fuel Filter Location
IMPORTANT: Replace the fuel filter only in a clean
area where the fuel line and connections will not be
contaminated by any dust and dirt.
1. Expand and slide clamps on either side of the
filter away from filter and pull fuel lines off filter.
2. Replace filter.
Fuel Filter - MTEFI
Model MTEFI is equipped with a high-volume, high-
pressure, 10-15 micron, in-line fuel filter. Replace-
ment of this filter is recommended every 1500 hours
of operation or more frequently under extremely
dusty or dirty conditions. Because the MTEFI has a
pressurized fuel system, fuel filter replacement
should be done by a Walker dealer or authorized
Kohler service dealer.
Blade Overload Shear Bolts
NOTE: Shear bolts are not used on the DSD52 or
DSD62 mower deck.
The cutting blade is keyed to the blade hub by two
(2) shear bolts (10-24 x 5/8 in. stainless steel ma-
chine screws). These bolts are designed to shear
and protect the blade drive gearbox from damage if
the blade encounters a shock load.
Cutting Blade Shear Bolts
NOTE: Tightening the 5/8-18 blade mounting nut
to 60 ft-lb (81.3 N
⋅
m) is also important for proper
shock load protection. It is important to not over-
tighten the mounting nut since this defeats (over-
rides) the function of the shear bolts.
If these bolts shear, remove the blade and install new
bolts. Refer to CHECKING/SERVICING in this sec-
tion for Sharpen Mower Blades which describes the
blade removal and installation procedure.
DANGER
Gasoline is extremely flammable and can
be highly explosive. To minimize danger:
•
Use only an approved fuel container for
gasoline.
•
DO NOT allow open flames or sparks
near the machine while performing main-
tenance or refueling; DO NOT smoke
while working with fuel.
•
Wipe up spilled gasoline immediately
and completely.
