<DIV>List, there are 2 ball and spring assemblies contained in the TR4 Purolator
Oil Control Head. I understand the function of the adjustable assembly. I don’t
understand the function of the non-adjustable ball and spring assembly. What
function does it serve? Might it be a relief valve for an over pressure within
the filter and if so does it somehow result in limiting full flow thru the
filter? <BR>I seem to recall reading about how the control head works a number
of years ago but can’t find that article now.</DIV>
<DIV>Thanks,</DIV>
