  • Page 37 CAUTION: When testing Alternator/Charging System: DO NOT disconnect positive lead(s) from the battery while the engine is running. With the engine stopped, disconnect lead(s), then perform test and stop engine before re-connecting. Connecting or disconnecting while the engine is running will send a voltage surge through the regulator, causing damage.
  • Page 38 350 Milliamp Charging System (+) POSITIVE LEAD CHECKING THE SYSTEM: The battery must be in the circuit to perform the test properly. Set the voltmeter to the 0-20 D.C. volt scale. Connect a voltmeter across the battery. The voltmeter should read battery voltage.

  • Page 56 Transaxle Troubleshooting In-Line Shift Models (i.e. 800, 820, 915, 920, 930 MST) Transaxle troubleshooting can be a mystery to many technicians, but by using a common sense approach that most technicians use for engine troubleshooting, the mystery will disappear and be replaced with confidence, skill and eventually, mastery of transaxle service.
  • Page 57 Hard Shifting Transaxles and Drive Belts Often hard shifting is blamed on an internal problem in the transaxle. To determine if the problem is transaxle or equipment related make these simple checks. 1. Turn the unit off so that all power is removed to the transaxle 2.
  • Page 58 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.

  • Page 61 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.
  • Page 62 TECUMSEH 2-CYCLE ENGINE OIL REQUIREMENTS The proper type and ratio of two cycle oil is critical to long life and low maintenance of the engine. The use of non certified oils and improper mix ratio’s can cause severe engine damage and possibly void warranty consideration.
