Merc Big end needle rollers
Hi,
Im just piecing together the last few bits for my 2.5 build. I have a new set of pro marine 4039 rollers to suit the metal cage big ends however the needle themselves are around .010” shorter than the original ones. When I install them they have a bit more movement over the standard rollers. Has anyone else come across this before?
