Troy-Bilt 630CN manual Bolotines, B. To Drain the TransmissionGear Oil

WARNING: Beforeinspecting, cleaning or servicing the machine,shut off engine, wait for all moving partsto come to a complete stop, disconnectspark plugwire and move wire awayfrom spark plug. Failureto follow these instructions can result in serious personal injury or property damage.

4.The gear oil level is correct if the gear oil is approximately halfway upthe side of the main drive shaft.

5.If the gear oil level is low. add gearoil as described next. If the gear oil level is okay,securely replacethe oil fill plug.

IMPORTANT:Do not operatethe tiller if the gear oil level is low. Doing so will result in severedamageto the transmission com- ponents.

6.If adding only a few ouncesof gear oil. useAPI rated GL-4or GL-5gearo11having a wscosEtyof SAE140. SAE85W-140 or SAE8OW-90. If refilling an empty trans- mzsszon,use only GL-4gear o11having a viscosity of SAE85W-140 or SAE140. IMPORTANT:Do not use automat=ctrans- mission fluid or motor oil in the transmis- sion.

7.While checking frequently to avoid

overfilling, slowly add gear oil into the oil fill holeuntil it reachesthe halfway point on the drive shaft.

8.Securely replacethe oil fill plug.

B. To Drain the TransmissionGear Oil:

Thetransmission gear oil does not needto bechanged unless it has beencontaminat- ed with dirt sand or metal particles,

1. Drain gasolinefrom the fuel tank or run

the engine until the fuel tank is empty. See "DANGER"statement below.

WARNING: Gasolineis highly flammable andits vapors are explosive. Followthese safety practicesto prevent personal injury or proper_y damage from fire or explosion.

,,Allowthe engineand mufflerto coolfor at least two minutes before draining the tiger'sgasolinetank.

•Do not allow open flames, sparks, matchesor smokingin the area.

•Wipe away spills and pushtiller away from spilled fuel.

•Use only an approved fuel container and store it safelyout of the reach of chil- dren.

•Do not store gasolinein an area where its vapors could reach an open flame or spark, or where ignition sources are present (such as hot water and space heaters, furnaces, clothes dryers, stoves, electric motors, etc.)

2.Drain the oil from the engine.

3.Removefour screws(B, Figure5-2) and removetransmissioncoverandgasket.

4.Removethe left-side wheel.

5.Tiltthe left-side wheel shaft into a drain panand allow the gearoil to drainthrough the top of the transmission.

6.Reinstall the wheel.

7.Install a new gasket (do not reuse old gasket and reinstall the transmission coy- er.

8.Refillthe transmission using GL-4 gear oil ,SAE85W-140 or SAE140L

9.Refillthe engine with motor oil and re- plenish the fuel tank with gasoline.

BOLOTINES

The bold tines will wear with use and should be inspected at the beginning of eachtilling seasonand after every30 oper- ating hours. The tines can be replacedel- ther individually or as acomplete set. See the Parts Lisl pagesfor tine identification and part numbers.

A. Tine Inspection:

With use the tines will becomeshorter. narrower and pointed. Badlyworn tines will result in a loss of tilling depth, and re- duced effectivenesswhen chopping up andturning under organic matter.

B. Removing4nstallinga Single Tine:

1.With the engineshut off and the spark plug wire disconnected removethe two screws IA,Figure5-3), Iockwahers IE)and nuts (B) that attach a single tine to a tine holder. If needed,use penetratingoil on the nuts.

2.When installing a single tine. besureto position it so that its cuttmg edge (sharp) will enter the soil first as the tiller moves forward.

C. Removing4nstallinga Tine Assembly:

1.A tine assemblyconsists of eight tines mounted on atine holder.

2.If removing both tine assemblies mark them "left" and "right" before removal. Removethe screw (C, Figure5-3), lock washer (E_and Iocknut (D/that securethe tine assembly to the tine shaft. If neces- sary, use a rubber malletto tap the tine as- sembly outward off the shaft.

3.Before reinstalling the tine assemo_y,in- spect the tine shaft for rust. roughspots or burrs. Lightly file or sand. as needed. Ap- ply athin coat of greaseto the shaft.

4.Install each tine assembly so that the cutting (sharp) edge of the tines will enter thesoilfirstwhenthetillermovesforward.
