D**L
all fit well and saw oiler now works properly
Akl the parts matched and fit correctly except for the "E" clip which was significantly too small. I used the old one plus I maintain stock of assorted E clips so this was not a negative for me.
L**S
Did not work
Back lip of oil pump not thick enough, that means the oil drive spring sets to low and will not engage drum
