Tighten Bolts and Nuts
Checkfor loose or missing hardware
every ten (10) operating hours. Failureto
tighten or replacefasteners cancause
poor performance, equipment damageor
oii leakage. Seeyour PartsCataiogfor

Most hardwareon your tiiier isvisibie.
Payparticuiar attentionto hardware
shown in Figures5-1,5=2, 5=3and 5=3A.
1. Checkthe transmission pulley
mounting bolt (Figure5-1). If the washer
behind the boit headis ioose, the boit
needstiglrtening. To do this, first insert a
punch or thick screwdriver into the hole
next to tire bolt and wedgethe tooi
against the sideof the motor mount
casting. This immobilizes the pulleywhile
you tighten the bolt.
2. Cireckjam nut on ieft side of neutral
plungerassembly(Figure5-2). If loose,
immobiiize bolt headwith onewrench and
useanother wrench to tighten the nut=
3. Checkthe three rear bearingcap
screws underthe depth regulator
mounting bracket (A, Figure5-3). If any
is loose, it cancause an oil leak or drive
shaft end play.
4. Checkthe five bolts securing thetiller
housingcover to the Ieftside of the trans-
mission (B in Figure5-3). Gearoil can
leakfrom a Dose housing cover. To
reachthe boits, removethe ieft side tine
hoider. SeeBnto TineMaintenanceinthis
Sectionfor tine holder removal directions.
5. Checkboth swing-bolts (C, Figure5=3)
that connectthe power unittransmission
to the tine attachment. Both bolts should
becheckedevery 2-1/2 hours of
operation, if ioose, wear canoccur on the
locating pin on tlre power unit, and cause
enlargement of the locating hole in the
tine attachment. Usinga torque wrench,
tighten these bolts to 70-to-80 ft.-ibs.
6. Checkthe iocknut that fastensthe
shifting iinkageto the eccentric shifting
lever (D, Figure5-3). Do not tighten the
Iocknut againstthe eccentric lever, it
should be very closeto, but not touching
the iever.
7. Checkthe four bolts and nuts securing
left and right tine holders to the tine shaft
(Figure5-3A).

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 lubrication of tire tilIer's rnechani=
cal parts is an essentialpart of good
maintenance. Lubrication should be done
after everyten (1O)hours of operation=
Useordinary motor oii (#30 weight or
lighter) where oii is specified. Usea
quaiity greasewith a metaiiubricant
where greaseis recommended(regular
grease isacceptable)=Do not over
lubricate. If there is a buiid=upof dirt,
removethe build=upand re=applyoil or
