FUEL RECOMMENDATIONS  
Today’s fuels have a s hort s helf life and it is recommended you buy no more than a two week  
s upply at a time.  
GASOLINE  
Tecumseh Products Company strongly recommends the use of fresh, clean, unleaded regular gasoline in  
all Tecumseh engines. Unleaded gasoline burns cleaner, extends engine life, and promotes good starting  
by reducing the build-up of combustion chamber deposits. Leaded gasoline, gasohol containing no more  
than 10% ethanol, premium gasoline, or unleaded gasoline containing no more than 15% MTBE (Methyl  
TertiaryButylEther), 15% ETBE (EthylTertiaryButylEther)or10% ethanol, can be used ifunleaded regular  
gasoline is not available.  
Reformulated gasoline that is now required in several areas of the United States is also acceptable.  
NEVER USE gasoline, fuel conditioners, additives or stabilizers containing methanol, gasohol containing  
more than 10% ethanol, unleaded regular gasoline containing more than 15% MTBE (Methyl Tertiary Butyl  
Ether), 15% ETBE (Ethyl Tertiary Butyl Ether) or 10% ethanol, gasoline additives, or white gas because  
engine/fuel system damage could result.  
Specialty Fuels : Fuels being marketed for use on small engines can have a significant affect on starting  
and engine performance. Prior to using any specialty fuel, the Reid Vapor Pressure (RVP) must be  
determined. Fuels with a rating ofless than 50 kPa (7psi)should notbe used in summer, and fuelwith a rating  
of 85 kPa (12psi) should not be used during winter.  
Storage: For year round fuel stability in and out of season, use “Ultra Fresh ” part number 730245A.  
FUEL ADDITIVES  
Only fuel additives such as Tecumseh’s fuel stabilizer Ultra Fresh part number 730245A or liquid varieties  
can be used when mixed properly. For winter applications, Isopropyl alcohol fuel dryers may be used in  
the fuel system but must be mixed at the proper ratio recommended by the manufacturer. NEVER USE  
METHANOL BASED DRYERS.

TECUMSEH 4-CYCLE LUBRICATION REQUIREMENTS  
We often get questions from both customers and dealers regarding the type and brand of oil we  
recommend.  
Tecumseh recommends the use of a high quality, brand name petroleum based oil in our engines.  
Very few air cooled engines have any type of oil filtration system, making regular oil changes  
critical to remove impurities from the engine and maximize engine life. Cons ult the operators or  
repair manual for the oil change interval and vis cos ity bas e on equipment operating temperature.

BASIC GEAR DRIVE TROUBLESHOOTING  
Hard Shifting Trans axles and Drive Belts  
Often hard shifting is blamed on an internal problem in the transaxle.  
To determine if the problem is trans axle or equipment related make thes e s imple checks .  
1
2
. Turn the unit off so that all power is removed to the transaxle  
. With the unit off move the shift lever through the shift gate. Movement of the lever should have only  
slight resistance. The shifting effort should be equal when the engine is off and when running. If the  
unit is difficult to shift the problem would be internal and the transaxle would need to be removed and  
repaired  
3
. If the unit shifts with ease, check the following areas that would be equipment related. Check to see if  
the belt is releasing from the pulley on the engine and transmission / transaxle, it may require that the  
belt guides be repositioned. The distance required from the pulley to the guide is typically 1/16" to 3/  
1
6" (1.6 mm - 4.8 mm), always check the O.E.M. specs.  
4
5
. Check to see if the pulley is damaged and may not be releasing the belt.  
. Make sure that the belt is the correct length and type in case it was replaced with a non original,  
possibly more aggressive belt.  
6
7
. Check the brake/clutch pedal to make sure that when the pedal is depressed that the idler pulley is  
releasing the belt tension before it applies the brake. If this does not happen the unit will still be under  
a load and be impossible to shift  
. The final area to check would be for damaged or binding shift linkage.  
Hard s hifting with the engine off could be caus ed by:  
1

4
. Shift linkage out of adjustment.  
. Corrosion in the transaxle or transmission.  
. Damaged shift keys, gears, or shifter brake shaft.  
. Belt guides missing or improperly adjusted (see equipment manufacturer specs.)  
Unit Seems to Slip:

. Check for proper belt adjustment (consult OEM operator’s manual).  
. Check for proper clutch/brake adjustment (consult OEM operator’s manual).  
. Check pulley condition and wheels for sheared or damaged keys.  
. Check drive belt condition, if glazed or worn replace it.

THIS DIMENSION  
VARIES FROM EACH  
MANUFACTURER  
(
1.6 mm - 4.8 mm)  
For proper declutching to occur, it is very important  
that the engine belt guide be set at a predetermined  
gap (set by the manufacturer) and away from the  
belt with the belt engaged.  
With clutch disengaged, it is very important that the  
belt blossoms away from the engine pulley. Belt  
must stop turning before transaxle shifting can  
occur.

VST Hydros tatic Model Troubles hooting  
The information on this page has been provided to help understand the internal operation of the VST. Do not use  
this information to attempt any internal repairs. Tecumseh's current policy on hydrostatic transaxles that have  
internal failures is to replace the complete unit. This has not changed. However, Tecumseh would like to provide a  
failure checklist to assist in making an accurate evaluation of the complete tractor to eliminate any unnecessary  
replacements. Here is a list of items to check and corrective actions to take.  
To properly test the unit for power loss.  
1

3
4
. Allow the unit to cool before trying the following steps.  
. Put the shift lever in a position that is 1/2 of the travel distance from neutral to forward.  
.
Place the tractor on a 17 degree grade.  
. Drive the tractor up the grade (without the mower deck engaged). The loss of power experienced should be  
approximately 20%. This is considered normal. If the loss of power is approximately 50%, this would be  
considered excessive.  
5
. Bring the unit to neutral, shift into forward and note the response. Care should be taken to move the lever  
slowly to avoid an abrupt wheel lift.  
To determine if the problem is with the hydro unit, all external problem possibilities must be eliminated. Here are  
some potential problem areas.  
1
. Overheating: Heat can cause a breakdown in the viscosity of the oil which reduces the pressure used to  
move the motor. Remove any grass, debris, or dirt buildup on the transaxle cover and / or between the  
cooling fins and fan. Buildup of material will reduce the cooling efficiency.  
2
. Belt s lippage: A belt that is worn, stretched, or the wrong belt (too large or wide) can cause belt slippage.  
This condition may have the same loss of power symptom as overheating. Typically, the unit which has a  
slipping belt will exhibit a pulsating type motion of the mower. This can be verified visually by watching the  
belt and pulley relationship. If the belt is slipping, the belt will chatter or jump on the pulley. If the belt is good,  
a smooth rotation will be seen. Replace the belt and inspect the pulley for damage.  
. Leakage: The VST and 1800 Series have two oil reservoirs which can be checked for diagnostic purposes.  
The first is the pump and motor expansion bellows, with a small diameter blunt or round nose probe, check  
the bellows depth through the center vent hole. Proper depth from the edge of that hole is 3-1/4 - 3-1/2  
inches (8.25 - 8.9 cm).  
3
The second chamber is for the output gears including the differential. FIRST make sure the tractor is level,  
then remove the drain/fill plug. NOTE: Some units that do not have differential disconnect will have two  
plugs. We recommend using only the primary plug. With a small pocket rule insert until you touch bottom of  
case. You can then remove it and check for 1/4 - 3/8 inches (6.5 - 9.5 mm) contact, this is full at its 8 oz.  
capacity.  
4
. Low ground s peed: If the linkage is not synchronized to absolute neutral, or the shift lever is not properly  
fastened to the tapered control shaft, full forward travel may not be achieved. This may cause a false  
reading and be misdiagnosed as a low power condition. This also could be caused by the brake not releas-  
ing.  
To determine absolute neutral, the hole in the tapered control shaft must face straight up and down, at this  
point make sure the OEM linkage is in neutral. To properly fasten the control lever to the shaft, torque the nut  
to 25-35 ft. lbs. (34 - 48.3 Nm) of torque with the shaft and the lever in neutral.  
When attaching the shifter arm to the shaft you must prevent any rotation during torquing. This can be done  
by placing a long 5/16 bolt in the hole of the shaft. Hold the bolt until the tapers are locked and the nut torque  
is correct.  
To make sure that the brake is not binding, drive the unit up a slight grade.. Position the speed control lever  
into neutral. The unit should coast backwards. If the unit does not coast back slowly, the brake is not  
released from the brake disk. Adjust the brake linkage to release the brake completely when the foot pedal  
is released.  
5
. Hard to s hift: Typically hard to shift symptoms are not caused by the hydrostatic unit. The shift arm should  
move with relative ease. Approximately 40-50 inch lbs. (4.48 - 5.6 Nm) at the transaxle for foot pedal units  
or 150-200 inch lbs. (16.8 -22.4 Nm) for hand operated units. This varies depending on the type of linkage.  
Binding may occur in the linkage connections due to rust or moisture. Lubricating these connections and  
checking for bent or damaged parts should resolve hard shifting.
