A large number of electrical components can be damaged very quickly using improper procedures and certain alternator components can be damaged by procedures that would not affect a D.C. generator. Observe the following to prevent unnecessary damage.

  1. Be sure that negative post of all batteries is grounded. This precaution should also be observed when connecting booster battery and charger.

  2. Never short across any alternator terminal.

  3. Never attempt to "polarize" alternator.

  4. Always disconnect all battery ground connections before removing or replacing any electrical unit.

  5. Never operate an alternator with an open circuit. Be sure that all leads are connected and tightened before starting the engine. Also, be sure that battery cables are not corroded or otherwise damaged leaving an open connection when engine is running.


The clutch can be unbolted from the flywheel and removed after tractor is split as outlined in paragraph 123. Loosen cap screws attaching pressure plate (5-Fig. 135) to flywheel gradually and diagonally across clutch to prevent distortion of pressure plate. Remove pressure plate and clutch disc (3) from flywheel.

Renew clutch disc if linings are loose, excessively worn, contaminated with oil or if there are signs of overheating due to clutch slippage. If there is evidence of oil or grease on clutch slippage, inspect engine and transmission oil seals for leakage and repair as needed before installing new clutch. On models with hydraulically actuated clutch linkage, the clutch release bearing slave cylinder is also a possible source of oil leakage.

    Didn't even tell me how to drain the radiator.
    December 13, 2015
    I ordered this book because I couldn't find a petcock to drain the antifreeze. If it doesn't have one and you have to remove the radiator to drain it , the book should say so or show you where the drain is.
    Maybe I will use the book for another refrence some day.

    Had the repair information I was looking for. You will have to be a mechanic to understand but I work on my own tractor most of the time so this was very helpful. I am needing to work on the front hub of my 6635. So far, this has given me what I needed, especially for the price.
