Troy-Bilt 664DM, E666MM manual Check Transmission Gear Oil Level, Attach Wheel Gear Lever

Incorrectcable adjustment could cause the wheels and tines to rotate unexpect- edly. Follow adjustment procedures carefully. Failure to do so could result in personalinjury or propertydamage.

4.Checkfor correct spring/cable tension as instructed in Section5, Checkingand Adjusting Forward Clutch Belt Tension.

5.When tension is correct, tighten the two jam nuts (B) securely.

STEP 5: CHECK TRANSMISSION

GEAR OIL LEVEL

The transmission was filled with gear oil

at the factory. However,be sure to check the oil level at this time to makecertain it

is correct.

IMPORTANT:Do not operatethe tiller if the gear oil level is low. Doing so will result in severedamageto the transmis- sion components.

1. With the tiller on level ground, pull the

Depth Regulator Lever (R, Figure 2-13) backand then slide it to the second notch

from the top. NOTE:If the lever does not move, lift the tine hoodflap and look for a

plastic tie securing the lever in place. Cut and removethe tie.

2.Removethe oil level check plug (M, Figure2-10) on the left-side of the trans- mission. (Due to dried paint on the plug threads, it may require some force to

removethe plug the first time.) The gear oil level is correct if oil starts to flow out

of the hole as the plug is removed. If so, securely reinstall the plug.

Figure2-11: Addinggearoil.

(b)If adding only a few ouncesof gear oil, use API rated GL-4 or GL-5 gear oil having a viscosity of SAE140, SAE85W- 140 or SAE80W-90. If refilling an empty transmission, use only GL-4 gear oil having a viscosity of SAE85W-140 or SAE140.

(c)Usinga clean funnel, slowly add gear oil until it flows from the gear oil level check hole (N, Figure2-11).

(d)Reinstall and tighten securely the gear oil fill plug (M, Figure2-10).

STEP 6: ATTACH WHEEL GEAR

LEVER

1.Insert the Wheel GearLever (P, Figure 2-12) up through the slot in the control panelthat is labeled"WHEELGEAR."

2.Insert two #10-32x 1/2" round head

screws down through the "+" marks on the control paneldecal and securely attach the wheel gear mounting bracket using two #10 Iockwashersand #10-32nuts.

3.Usea small board to tap the Wheel GearLever knob securely onto the lever.

4.Securethe wheel gear cable and the reverseclutch control cableto the left- side handlebarwith two plastic ties (S, Figure2-13) locatedabout two feet apart. Snip off any excesstie length with scissors.

positive terminal to help protect it from corrosion.

3.Removethe hex bolt and hex nut from the negativecable (heavy blackwire).

4.Removethe black plastic cover from the negativebattery terminal and attach the negativecableto the negativebattery terminal (-) with the bolt and hex nut.

IMPORTANT:

•If the battery is put into service after the date shown on top of battery, chargethe battery as instructed in the Maintenence section of this manual prior to operating the tiller.

STEP 8: CHECK AIR

PRESSURE IN TIRES

3.If oil does not flow from the check hole, add oil as follows:

NOTE:Do not use automatic transmission fluid or motor oil in the transmission.

(a)Cleanareaaround the fill hole (N, Figure2-11) and unscrew gear oil fill plug.

STEP 7 ATTACHING THE BATTERY

CABLES (MODEL E666M)

The positive battery terminal is marked Pos. (+). The negative battery terminal is marked Neg. (-).

1.Removethe hex bolt and hex nut from the positive cable (heavy red wire).

2.Removethe plastic cover from the positive battery terminal and attach the positive cableto the positive battery ter- minal (+) with the bolt and hex nut. Make certain that the rubber boot covers the

Usea tire pressuregaugeto check the air pressure in both tires. Deflateor inflate both tires equally to between15 PSI and 20 PSI). Besure that both tires are

inflated equally or the unit will pull to one side.

STEP 9: CHECK HARDWARE

FOR TIGHTNESS

Inspect the hardware on the unit and tighten any loose screws, bolts and nuts.
