2. Foldthe top section of the assembly
backward (2, Figure 5-16). Guidethe
cables carefully while folding. Besure
not to bend, pinch, or stretch the cables.
IMPORTANT:To avoid damageto cables,
always fold the top section of the
handlebarassembly backwardand the
bottom section forward.
3. Still supporting the handlebar
assembly with one hand, loosen the two
lower handlebaradjustment knobs
(3, Figure 5-16) just enoughto dislodge
both handlebarstruts (L, Figure5-17)
from the slots (K) in the wheelbracket
assembly.
NOTE: The handlebar height could inad-
vertently change if the lower adjustment
knobs are loosenedexcessivelyduring
this step.
4. Carefullyfold the bottom section of
the handlebarassembly forward overthe
engine (4, Figure 5-16). Guidethe cables
carefully while folding. Besure not to
bend, pinch, or stretch the cables;also,
keepcablesaway from muffler-- the
outer cable covering can be burned if the
engine is still hot.
5. To unfold handlebarassembly,
perform folding steps in reverseorder.
PINIONGEARSERVICE
The mower drive wheels (rear wheels)
each contain a pinion gear. This gear
transfers drive power to the wheels which
propels the mower forward. It is very
important to keepthese internal parts
clean. The following procedure explains
how to disassemble, clean and reassem-
blethe mower drive wheels. Conductthis
maintenanceon the pinion gears after
every 50 operating hours.
Figure5-18: Drive wheel assembly.
Tools and Materials
• 9/16" Socketand Ratchet
• Small Snap-Ring Pliers
• Cleaning Rags
Procedure
NOTE: This procedure is done only on
the drive wheels (rear wheels).
1. Placea sturdy, stable block under the
mower to elevatea rear wheel off the
ground.
2. Usea 9/16" wrench to removewheel
assembly (A, B, C,D, E,Figure 5-18).
3. Removesnap-ring (J, Figure5-18)
from axle.
4. Removeshim(s) (I, Figure5-18). The
number of shims vary from mower to
mower. Put them nextto the snap-ring.
5. Pull off pinion gear (H, Figure5-18).
6. Removedrive pin (G, Figure5-18).
7. Remove plastic washer/seal
(F, Figure5-18).
8. Thoroughly cleanoff debris from the
drive pin, axle, hole in axle (for drive pin)
and the washer/seal.
9. Reinstall washer/seal (F,Figure 5-18).
Besure to install flat side of washer
against bearing(mower deck).
10. Insert the drive pin (G,Figures5-18)
into the hole in the axle.
NOTE: The pin should slide freely within
the hole.
11. Thoroughly cleanpinion gear,
including surface areaand cavity.
12. Slidethe pinion gear (H, Figure5-18)
onto the axle with the cavity toward the
mower. Pressthe gearfirmly against the
washer/seal (F, Figure5-18). Be certain
that the gear isflush against the surface
of the washer/sealand that the
washer/seal is flush against the wheel
mounting bracket.
18. Slidethe shims (I, Figure 5-18) onto
the axle and against the pinion gear. Be
sure to install the same number of shims
as were removedfrom the unit.
14. Install the snap-ring onto the axle
(J, Figures 5-18) and into the groove in
the axle. Pullthe pinion gear outward to
besure that the snap-ring seats properly.
NOTE: If you can't get the snap-ring into
the slot in the axle, press the pinion gear
more firmly against the washer/seaL Do
not leaveoff shims.
15. Insert wheel screw (A, Figure
5-18) through wheel (B), flat washer (C),
center hole in wheel shield (D), and
spacer (E). The wheel shield has a double
edge on the rim. Position this side
toward the wheel.
16. Align pinion gear with the hole in the
wheel shield. At the same time, align the
wheel screw with the welded nut on the
wheel bracket and tighten securely.
