To Change Engine OIL, Lubrication | Craftsman 917.28991 specs

NOTE: The original equipment battery on

your tractor is maintenance free. Do not attempt to open or remove caps or covers.

Adding or checking level of electrolyte is not necessary.

TO CLEAN BATTERY AND TERMINALS

Corrosion and dirt on the battery and termi- nals can cause the battery to "leak" power.

1.Remove terminal guard.

2.Disconnect BLACK battery cable first then RED battery cable and remove battery from tractor.

3.Rinsethe batterywith plain waterand dry.

4.Clean terminals and battery cable ends with wire brush until bright.

5.Coat terminals with grease or petroleum jelly.

6.Reinstall battery (See "REPLACING BATTERY" in the SERVICE AND AD-

JUSTMENTS section of this manual).

TRANSAXLE COOLING

Keep transaxle free from build-up of dirt and chaff which can restrict cooling.

TO CHANGE ENGINE OIL

Determine temperature range expected

before oil change. All oil must meet API

service classification SG-SL.

•Be sure tractor is on level surface.

•Oil will drain more freely when warm.

•Catch oil in a suitable container.

1. Remove oil fill cap/dipstick. Be careful not to allow dirt to enter the engine when changing oil.

2.Remove yellow cap from end of drain valve and install the drain tube onto the fitting.

3.Unlock drain valve by pushing inward slightly and turning counterclockwise.

LUBRICATION

Only use high quality detergent oil rated

with API service classification SG-SL.

Select the oil's SAE viscosity grade according to your expected operating temperature.

NOTE: Although multi-viscosity oils (5W30, 10W30 etc.) improve starting in cold weather, they will result in increased

oil consumption when used above 32°R Check your engine oil level more frequent- ly to avoid possible engine damage from running low on oil.

Change the oil after every 50 hours of op- eration or at least once a year if the tractor

is not used for 50 hours in one year, Check the crankcase oil level before

starting the engine and after each eight

(8)hours of operation. Tighten oil fill cap/ dipstick securely each time you check the oil level.

4.To open, pull out on the drain valve.

5.After oil has drained completely, close and lock the drain valve by pushing inward and turning clockwise until the pin is in the locked position as shown.

6.Remove the drain tube and replace the cap onto the end of the drain valve.

7.Refill engine with oil through oil fill dip- stick tube. Pour slowly. Do not overfill.

For approximate capacity see "PROD-

UCT SPECIFICATIONS" section of this manual.

8.Use gauge on oil fill cap/dipstick for checking level. Insert dipstick into

the tube and rest the oil fill cap on the tube. Do not thread the cap onto the

tube when taking reading. Keep oil at "FULL' line on dipstick. Tighten cap onto the tube securely when finished.

ENGINE OIL FILTER

Replace the engine oil filter every season or every other oil change if the tractor is used more than 100 hours in one year.
