I have the same issue and have stipped it down to a point but am unable to stip the fron of completley. Have taken the fron off but there is still the internal front piece holding on to the fron of the drum which is stopping me fromgetting in to pully system to grease.
How do youget tht off. I have removed the 4 bolts but it will not lift and can not see anymore bolts / screws holding it in it just will not lift out
