EN40B Steel Crankshaft with 12 bolt Flange & Full Lip Seal

Steel crankshaft for TR 4 cylinder engines. Made in the UK from EN40B steel billet. It is fully cross-drilled so the oil ways run end to end. The rear crankshaft flange has a 12 bolt fixing and accepts a full circle lip seal for improved oil-retention. We also offer a range of steel flywheels to suit this crankshaft for both standard and up-rated size 8.5" / 215mm clutches and 7.25" /184mm race clutches.
