▁Cl utch ▁installation ▁Currently , ▁three ▁variations ▁of ▁cl utch ▁installation ▁are ▁used . ▁The ▁original ▁design ▁used ▁a ▁concent ric ▁arrangement , ▁where ▁both ▁cl ut ches ▁shared ▁the ▁same ▁plane ▁when ▁viewed ▁per pend icular ly ▁from ▁the ▁transmission ▁input ▁sh aft , ▁along ▁the ▁same ▁centre ▁line ▁as ▁the ▁engine ▁c rank sh aft ; ▁when ▁viewed ▁head - on ▁along ▁the ▁length ▁of ▁the ▁input ▁sh aft , ▁this ▁makes ▁one ▁cl utch ▁notice ably ▁larger ▁than ▁the ▁other . ▁ ▁The ▁second ▁implementation ▁uses ▁two ▁single - plate ▁dry ▁cl ut ches ▁– ▁side - by - side ▁from ▁the ▁per pend icular ▁view ▁but ▁again ▁sharing ▁the ▁centre ▁line ▁of ▁the ▁c rank sh aft . ▁ ▁A ▁later ▁variation ▁uses ▁two ▁separate ▁but ▁ident ically ▁s ized ▁cl ut ches . ▁These ▁are ▁arranged ▁side - by - side ▁when ▁viewed ▁head - on ▁( al ong ▁the ▁length ▁of ▁the ▁input ▁sh aft ▁and ▁c rank sh aft ▁centre ▁line ), ▁and ▁also ▁share ▁the ▁same ▁plane ▁when ▁viewed ▁per pend icular ly . ▁This ▁latter ▁cl utch ▁arrangement ▁( un like ▁the ▁other ▁two ▁variations ) ▁is ▁driven ▁by ▁a ▁g ear ▁from ▁the ▁engine ▁c rank sh aft . ▁ ▁Supp liers ▁ ▁Borg W ar ner ▁Borg W ar ner ▁Inc . ▁supplies ▁wet ▁dual ▁cl ut ches ▁and ▁electro h yd ra ul ic ▁control ▁modules ▁( me chat ron ics ) ▁for ▁these ▁dual - cl utch ▁transm issions ,
