PRIMARY GEAR FRONT FLOATING BUSH 1275cc

This is our racers favourite way of dealing with the worn or troublesome front primary gear bush.(this is NOT the top hat type rear bush)22.5mm wide. PLEASE NOTE: This floating bush is not suitable for early Cooper S primary gears (which have a larger internal diamension), original A+ helical primary gears OR our own straight cut primary gears manufacturered before 2015. They are ok on Minispares manufactured helical gears and straight cut gears after 2015. Ideal for use on the stepped type 1275cc type cranks this bush is fully floating and does not require the extra costs of fitting and machining. Always ensure that the bush buts up squarely to the shoulder with the oil holes in the trough and not on the edge of the stop step, as the oil drain holes can act as cutting tips on the edge of the bush. Remove old bush and clean area with wet and dry, check the inner bush area is not machined on an angle by the oil hole as this will shred the new floating bush, this is how most A plus gears were machined. Remove old bush and clean area with wet and dry, stick in the new oiled bush and you are ready to go. Another product developed by Minispares technical department.
