Re: 1995 V4 115 hp Johnson piston clearence to bore
I dont know how you can get interferance between the piston and the bore...pistons dont get bigger over time and bores dont get smaller over time!I have a 1995 115 and its manual....they had two different models that year. on my model a 60 degree looper the book does not specify the spec you asked for. there is a standard manufacture bore dia. of 3.5995-3.6005. they give some specs on the piston...its cant taper more than .002, it cant be out of round by more than .004, and the dia measure at two places 90 degrees apart cant vary by more than .003
they say the bore cant be OVERSIZE more than .004
thats a lot of over lapping dimensions...... they also give a ring end gap.....which is important
i dont know for sure, but I would suspect the crossflow motors have similar tolerance....even if the measurements are different.
