Fuel Filter; Blade Overload Shear Bolts - Walker T27i Operator's Manual

T27i

Fuel Filter

Gasoline is extremely flammable and can
be highly explosive. To minimize danger:
● Before servicing the fuel system:
1. Disconnect the spark plug leads.
2. Disconnect the negative (-) battery
cable from battery.
Use only an approved fuel container for
●
gasoline.
● DO NOT allow open flames or sparks
near the machine while performing
maintenance or refueling;
smoke while working with fuel.
● Wipe up spilled gasoline immediately
and completely.
Model T27i is equipped with an in-line fuel filter
between the fuel tank and the fuel pump (low pres-
sure fuel pump). Visually inspect the filter periodi-
cally, and replace the filter yearly. Use Walker P/N
5020-3 or Kohler P/N 24-050-13, 9-12 microns for
replacement filter.
Fuel Filter Location
IMPORTANT: Replace the fuel filter only in a clean
area where the fuel line and connections will not
be contaminated by dust and dirt.
1. Expand and slide clamps on either side of the
filter away from filter and pull fuel lines off filter.

Maintenance Instructions
2. Replace filter, making sure that the arrow on
the filter is aligned with the fuel flow through
the filter.
3. Verify that the fuel lines and clamps are se-
curely attached, and that no fuel leaks are
present.

Blade Overload Shear Bolts

NOTE: Blade shear bolts are not used on belt-
driven decks.
On gear-driven decks, each cutting blade is keyed
to the blade hub by two (2) shear bolts (10-24 x
5/8 in. stainless steel machine screws). These
bolts are designed to shear and protect the blade
drive gearbox from damage if the blade encounters
a shock load.

NOTE: Tightening the 5/8-18 blade mounting nut
to 60 lb·ft (81 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 Sharpen Mower Blades on
page 73 which describes the blade removal and
installation procedure.
After reinstalling the blade, check blade timing (on
gear-driven decks) by moving blades through one
(1) complete revolution. Make sure blade tips
pass clear of each other. If timing is incorrect,
contact your Walker dealer.
