Troy-Bilt 664D-Pony manual Maintenance, Check For Oil Leaks, Transmission Gear Oil Service

18Section 5: Maintenance

WARNING

Before inspecting, cleaning or servicing the machine, shut off engine, wait for all moving parts to come to a complete stop, disconnect spark plug wire and move wire away from spark plug. Remove the key from the keyswitch on units so equipped.

Failure to follow these instructions can result in serious personal injury or property damage.

CHECK FOR OIL LEAKS

Before each use, check your tiller for signs of an oil leak – usually a dirty, oily accumulation either on the unit or on the floor where it has been parked.

A little seepage around a cover or oil seal is usually not a cause for alarm. However, if the oil drips overnight then immediate attention is needed as ignoring a leak can result in severe transmission damage.

If a cover is leaking, try tightening any loose screws or bolts. If the fasteners are tight, a new gasket or oil seal may be required. If the leak is from around a shaft and oil seal, the oil seal probably needs to be replaced. See your autho- rized dealer or contact the factory for service or advice.

IMPORTANT: Never operate the tiller if the transmission is low on oil. Check the oil level after every 30 hours of operation and whenever there is any oil leakage.

TRANSMISSION GEAR OIL SERVICE

Check the transmission gear oil level after every 30 hours of operation or whenever you notice any oil leak. Operating the tiller when the transmission is low on oil can result in severe damage.

A. To Check Transmission Gear Oil Level:

1.Check the gear oil level when the trans- mission is cool. Gear oil will expand in warm operating temperatures and this expansion will provide an incorrect oil level reading.

2.To check the gear oil level (and to add oil, if necessary), refer to “STEP 5: Check Gear Oil Level in Transmission” in Section

2of this manual.

B. To Drain and Refill the Transmission:

The transmission gear oil does not need to be changed unless it has been contami- nated with dirt, sand or metal particles.

1.Prop up the left side of the unit so that it will be securely supported when the left side wheel is removed. Remove the left side wheel by removing the wheel mount- ing hardware.

2.Unscrew the plastic gear oil fill plug from the top of the transmission.

3.Place a clean pan below the transmis- sion drain plug (see Figure 5-3) and remove the drain plug. The oil will start flowing out of the drain hole (it may flow slowly, especially in cold temperatures).

4.Remove the transmission gear oil level check plug that is located a few inches above the left side wheel shaft.

5.When the oil stops flowing, tilt the transmission forward to drain oil from the rear of the transmission.

6.After draining the oil, clean the threads of the drain plug, apply a non-hardening removable gasket sealant to the threads, and securely reinstall the drain plug.

7.Using a clean funnel, slowly add SAE

140or SAE 85W-140 weight gear oil (with an API rating of GL-4 only) to the transmission. The transmission holds approximately 3-1/4 pints (52-54 ounces). Tilt the tiller slightly backwards to make sure the gear oil reaches the rear (tine) end of the transmission. Stop adding gear oil when it begins to flow from the oil level check hole on the side of the transmission.

8.Securely reinstall the oil level check plug.

9.Securely reinstall the gear oil fill plug on top of the transmission.

10.Reinstall the wheel and remove the prop.
