youve broken a retaining strap for the pressure plate. and the diaphram spring is bent,
i did 3 in my dr30. heaps ghey
pull it out coz it will only get worse. i let it go for a while till it broke the front off my gearbox
ps.... this is if its heaps bad like really shaking hard.
if its just minor like a slight vibration. it should be ok. but ide get it checked.
the cause for vibration is the spring being bent
