How to put the spring back into your cylinder head
Rebuilding your John Deere, Deutz or Perkins cylinder head? Here is a no-cost way to extend valve spring life. Simply polish each end of the valve spring in a figure-eight motion with 200-grit emery paper. This cross hatching helps to hold the oil to the metal surface increasing the effectiveness of the lubrication. This works especially well on cylinder heads with two sets of valve springs (inner and outer) such as some Perkins marine engines and John Deere engines. On Continental flathead valve springs remember that the coils once polished must be placed with the end with the tightened windings pointed down toward the oil pan.
