BMW M2 M3 M4 F8x S55 Engine Crank Hub Issue !
CRANK TECHNICS CRANK HUB KIT FOR ALL BMW WITH S55 ENGINE M2C / M3 / M4 WITH CAPTURE PLATE
ISSUES RELATING TO THE STANDARD THREE-PIECE CRANK HUB ON THE S55 ENGINE ARE WIDELY KNOWN
BUT THESE ARE FULLY ADDRESSED WITH THE INSTALLATION OF THE CRANKTECHNICS PERFORMANCE ONE-PIECE BILLET CRANK HUB AND CAPTURE PLATE.
THE OE UNITS FRICTION PLATE ARE KNOWN TO SLIP, CAUSING THE TIMING TO ALTER ENOUGH THAT PISTON-TO-VALVE CONTACT CAN OCCUR
AND IF NOT TOTALLY STANDARD AND WITHIN THE WARRANTY PERIOD, LEAVES OWNERS WITH A VERY EXPENSIVE REPAIR BILL!
WE KNOW OF THIS PROBLEM ONLY TOO WELL, HAVING EXPERIENCED THIS ISSUE TWICE OURSELVES, SO WE WERE COMMITTED TO DEVELOPING A PRODUCT THAT WOULD
ENSURE OWNERS OF STANDARD POWER OUTPUTS HAVE COMPLETE PEACE OF MIND, AS MUCH AS THOSE THAT WISH TO INCREASE THE POWER AND TORQUE OUTPUT WITHOUT
HAVING TO WORRY; CRANKTECHNICS HAVE ENGINEERED THE MOST COMPREHENSIVE SOLUTION ON THE MARKET AND AT ONE OF THE MOST COMPELLING PRICE POINTS.
THE CRANKTECHNICS PERFORMANCE ONE-PIECE CRANK HUB IS MACHINED FROM BILLET EN36 THAT'S BEEN HEAT-TREATED WITH A 0.75MM CASE HARDENING
MAKING IT INCREDIBLY STRONG AND DURABLE.
THE ONE-PIECE DESIGN ENSURES THE FRICTION PLATES CAN'T SLIP AND WITH A NEW CRANK BOLT TIGHTENED APPROPRIATELY, THIS ALONE DELIVERS A SUBSTANTIAL
IMPROVEMENT IN RELIABILITY VERSUS THE OE VERSION.
FOR THE ULTIMATE SOLUTION, WHICH THEN ALSO REMOVES THE POSSIBILITY FOR THIS BOLT TO BE ABLE TO LOOSEN, WE'VE ENGINEERED AN ADDITIONAL BILLET ALUMINIUM
CAPTURE PLATE THAT SECURELY HOUSES THE WHOLE HEAD OF THE CRANK BOLT, MAKING IT IMPOSSIBLE FOR IT TO COME UNDONE.
CAREFUL DESIGN HAS ALSO ALLOWED US TO DEVELOP A SOLUTION THAT'S EASY TO INSTALL COMPARED TO SOME OTHER PRODUCTS AS THERE'S NO DRILLING OR
MODIFICATION REQUIRED TO THE OE CRANKSHAFT, WHICH SAVES YOU TIME AND ULTIMATELY MONEY, TOO.
THE ACHILLES HEEL OF BMW’S S55 (F8X M2 COMPETITION/M3/M4) IS THE CRANK HUB.
FROM FACTORY, THE CRANK HUB AND ASSOCIATED TIMING/PUMP DRIVE SPROCKETS ARE ALL SEPARATE PIECES ONLY HELD TOGETHER WITH FRICTION APPLIED BY A LARGE CENTRAL BOLT.
WITH AGGRESSIVE DRIVING AND/OR TUNED ENGINES WITH INCREASED TORQUE OUTPUTS
THE TIMING CHAIN SPROCKET CAN SLIP ON THE HUB
OR THE HUB ITSELF CAN SLIP CAUSING RUNNING PROBLEMS, ENGINE DAMAGE OR CATASTROPHIC ENGINE FAILURE.
THE TIMING SPROCKET IS NOW A SINGLE PIECE WITH THE HUB, AND THE HUB USES SPLINE LOCK TECHNOLOGY TO POSITIVELY LOCK THE HUB TO THE CRANK.
UNLIKE RIVAL PRODUCTS, NO DRILLING OF THE CRANKSHAFT IS REQUIRED.
