Description Reviews OEM MINI Crank Bolt. This should be replaced anytime you remove the crank pulley. This bolt is brand new and comes with thread locker already applied on the M12 x 1.75 threads. But a special step we always do at the shop is to add some red thread locker as well to make sure the bolt does not come back out. Sold individually and you only need one. Will fit gen 1 Cooper or Cooper S (R52, R52, R53). Note: Tq. to 88 ft. lbs.
