I am in need of a replacement e-unit drum for my PW 681 engine. I have heard that some of the plastic in the newer e unit drums are prone to warp from the heat and some have issues with extra plastic flashing near the 'gear teeth'. I am afraid to buy one on-line (ebay or parts guys) not knowing if it is a good one or a cheaply made one.
Can anyone recommend a good e-unit drum, or does anyone have a NOS/used one they can sell me that is in good shape?
Thanks,
Andy
