631D, 633D, 637D TractorsA new procedure is used to tighten the flywheel housing bolts. This will prevent leaks at the gasket between the flywheel housing and the cylinder block. If oil leaks have been a problem at this location on an engine, the installation of a new gasket and use of the new tightening procedure will stop the leaks. Do not use a gasket sealer with the gasket. The gasket sealer can cause the gasket to become soft and the result is another oil leak. Make a note of the new procedure in your Service Manuals until the Service Manuals are changed.
