NOTE:
Use a high quality detergent engine oil with API classification SF, SG, SH, SJ or higher for gasoline engines.
See Briggs and Stratton Vanguard Model 2900000 Service Manual for further information regarding
oil recommendation.
Using multi-grade oils (5W-30, 10W-30, and 10W-40) may increase oil consumption. If multi-grade oil is used, check
the oil level more frequently.

If the plug is oily or has carbon built up on it, clean the plug using a high flash-point solvent and a wire brush or
other suitable tool.
3.
If the spark plug electrodes are corroded or damaged, or if the insulator is cracked, replace the plug with an
OEM replacement.

Spark Plug Torque: 180 in-lb (20 Nm)
SPARK PLUG GAP INSPECTION
1.
Measure the gap with a wire-type thickness gauge.
2.
If the gap is incorrect, carefully bend the side electrode with a suitable tool to obtain the correct gap.

Spark Plug Gap: 0.030 in. (0.76 mm)
GEARCASE LUBRICATION
NOTE:
Dispose of used oil according to the environmental laws and regulations for your area.
LUBRICATION LEVEL CHECK – FRONT DIFFERENTIAL AND REAR TRANSAXLE
1.
The front differential is equipped with two oil port plugs (1 and 2)
. When the vehicle is on a
level surface, use the level indicator hole (upper plug) (1) as a lubricant level indicator. Lubricant level should
be even with the bottom of level indicator hole (1).
