Section5:
Before inspecting, ¢meaning o r servicing the machine, shut off engine, wait for all moving parts to come
to a ¢ompmete stop, disconnect spark plug wire and move wire away from spark plug. Remove ignition
key, if so equipped,
Failure to follow these instructionscan result in serious persenam injuryor propertydamage.
Tighten Bolts and Nuts
Checkfor loose or missing hardware
every ten (10) operating hours. Failureto
tighten or replacefasteners can cause
poor performance, equipment damage or
oii leakage. See your Parts Cataiog for
complete fastener descriptions.
Most hardware on your tiiier is visibie.
Payparticuiar attention to hardware
shown in Figures5-1,5=2, 5=3and 5=3A.
1. Checkthe transmission pulley
mounting bolt (Figure 5-1). If the washer
behind the boit head is ioose, the boit
needs tiglrtening. To do this, first insert a
punch or thick screwdriver into the hole
next to tire bolt and wedgethe tooi
against the side of the motor mount
casting. This immobilizes the pulley while
you tighten the bolt.
2. Cireckjam nut on ieft side of neutral
plunger assembly(Figure5-2). If loose,
immobiiize bolt head with one wrench and
useanother wrench to tighten the nut=
3. Checkthe three rear bearing cap
screws under the depth regulator
mounting bracket (A, Figure5-3). If any
is ioose, it can cause an oil leak or drive
shaft end play.
4. Checkthe five bolts securing the tiller
housing cover to the Ieft side of the trans-
mission (B in Figure 5-3). Gear oil can
leakfrom a ioose housing cover. To
reachthe boits, remove the ieft side tine
hoider. See Bnto TineMaintenancein this
Section for tine holder removal directions.
5. Check both swing-bolts (C, Figure5=3)
that connect the power unit transmission
to the tine attachment. Both bolts should
be checked every 2-1/2 hours of
operation, if ioose, wear can occur on the
locating pin on tlre power unit, and cause
enlargement of the locating hole in the
tine attachment. Using a torque wrench,
tighten these bolts to 70-to-80 ft.-ibs.
6. Checkthe iocknut that fastens the
shifting iinkageto the eccentric shifting
lever (D, Figure5-3). Do not tighten the
Iocknut against the eccentric lever, it
should be very close to, but not touching
the iever.
7. Checkthe four bolts and nuts securing
left and right tine holders to the tine shaft
(Figure 5-3A).
Figure 5=1: Check bolt on transmission pulley.
JNtPORTANT: Give screws or bolts tlrat
go into the transmission housing a
coating of non=hardening gasket seaiant
to prevent gear oil from leaking.
Tiller Lubrication
Proper Iubrication of tire tiIIer's mechani=
cai parts is an essential part of good
maintenance. Lubrication should be done
after every ten (1O)hours of operation.
Use ordinary motor oii (#30 weight or
lighter) where oii is specified. Use a
quaiity grease with a metai iubricant
where grease is recommended (regular
grease is acceptable). Do not over
lubricate. If there is a buiid-up of dirt,
remove the build-up and re-apply oil or
g tease.
