REFLECTOR: Franklin Oil temp and flow data

[Brian Michalk]

Has yours always been this way?  I found this thread from a Maule owner:

-------------
Update! I pulled the bypass plate off and tore it apart. I found that 
the plunger on the relief side is scarred and would not freely fall out 
on its own without a little persuasion. Also there is a washer located 
between the end cap and the spring. Am I thinking right that a washer in 
this position would give more pressure?? Should I remove the washer and 
check pressures? Now I am in need of some parts mainly a new gasket. I 
believe I can clean the plunger up with a piece of Emory cloth. It's not 
too bad. Any advice on anything would greatly be appreciated. Not to 
many maule gurus let alone franklin guys in my neck of the woods.

I have taken mine apart, years ago to reverse engineer it.  I don't 
recall any sticking parts.
