REPAIR INSTRUCTIONS

Be sure unit is vertical, so that the countershafts will not fall out when the case is removed.

40.Using a hoist and chain, remove the rear case from the main case. Only the rear case should be lifted, not the output assembly. If necessary, tap on the end of the output shaft to loosen it from the case. Lift only the case, not the compound gear set or mainshaft and synchronizer assembly.

41.For the extended output shaft transmissions: T313–T318(21)(L21)(LR21), using a hoist and suitable output yoke retaining nut with welded strap, lift and remove the synchronizer and output shaft assembly.
