PRIMARY GEAR FRONT FLOATING BUSH 1275cc

Not for A Plus OR some straight cut. 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

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.

FULLY-FLOATING PRIMARY GEAR BUSH


Countless Mini enthusiasts have been dogged by primary gear bush hassles on 1275-based engines - in particular the one nearest the block (the front one). Worn ones are expensive and difficult to replace for the DIY-er because they need machining to the correct size, a job that needs to be done very accurately - a particular problem for over-seas enthusiasts.

C-AEA3240 - Replacement Fully-floating Primary Gear Bush. For 1275-Type primary Gears only


This bush is made to fit as many known 1275 primary gears - both helical and straight cut - as possible that use the original 22G109 type bush. There may be some exceptions where the manufacturer uses a slightly shallower bush housing
